Prerequisites and Limitations for Creating and Managing Oracle Databases on Oracle Exadata Database Service on Dedicated Infrastructure

Review the prerequisites for creating and managing Oracle Databases on Oracle Exadata Database Service on Dedicated Infrastructure.

Before you can create and use an Oracle Database on Exadata Cloud Infrastructure, you must:

  • Provision Exadata Cloud Infrastructure infrastructure
  • Configure a VM cluster
  • Create any required backup destinations

You can create one or more databases on each Oracle Exadata Database Service on Dedicated Infrastructure system. Other than the storage and processing limits of your Oracle Exadata system, there is no maximum for the number of databases that you can create. By default, databases on Exadata Cloud Infrastructure use Oracle Database Enterprise Edition - Extreme Performance. This edition provides all the features of Oracle Database Enterprise Edition, plus all of the database enterprise management packs, and all of the Enterprise Edition options, such as Oracle Database In-Memory, and Oracle Real Application Clusters (Oracle RAC). If you use your own Oracle Database licenses, then your ability to use various features is limited by your license holdings. TDE Encryption is required for all cloud databases. All new tablespaces will automatically be enabled for encryption.

Oracle Database Releases Supported by Oracle Exadata Database Service on Dedicated Infrastructure

Learn about the versions of Oracle Database that Oracle Exadata Database Service on Dedicated Infrastructure supports.

Exadata Cloud Infrastructure supports the following Oracle Database software releases:

  • Oracle Database 19c (19.0)
  • Oracle Database 12c Release 2 (12.2) (requires a valid Upgrade Support contract).
  • Oracle Database 12c Release 1 (12.1) (requires a valid Upgrade Support contract).
  • Oracle Database 11g Release 2 (11.2) (requires a valid Upgrade Support contract).

For Oracle Database release and software support timelines, see Release Schedule of Current Database Releases (Doc ID 742060.1) in the My Oracle Support portal.

Provisioning and Managing Exadata Databases

This topic describes creating and managing Oracle Databases on an Exadata Cloud Infrastructure instance instance.

In this documentation, "database" refers to a container database (CDB). When you provision a database in an Exadata cloud VM cluster, the database includes an initial pluggable database (PDB). For more information on these resource types, see Multitenant Architecture in the Oracle Database documentation. See Exadata Pluggable Database Operations for more information on pluggable databases in Exadata Cloud Infrastructure.

You can create Database Homes, databases, and pluggable databases at any time by using the Console or the Database APIs.

When you add a database to a VM cluster on an Exadata instance, the database versions you can select from depend on the current patch level of that resource. You may have to patch your VM cluster to add later database versions.

After you provision a database, you can move it to another Database Home. Consolidating databases under the same home can facilitate management of these resources. All databases in a given Database Home share the Oracle Database binaries and therefore, have the same database version. The Oracle-recommended way to patch a database to a version that is different from the current version is to move the database to a home running the target version. For information about patching, see Patching an Exadata Cloud Service Instance.

Note

When provisioning databases, make sure your VM cluster has enough OCPUs enabled to support the total number of database instances on the system. Oracle recommends the following general rule: for each database, enable 1 OCPU per node. See To scale CPU cores in an Exadata Cloud Service cloud VM cluster or DB system for information on scaling your OCPU count up or down.

When you create an Exadata database, you can choose to encrypt the database using your own encryption keys that you manage. You can rotate encryption keys, periodically, to maintain security compliance and, in cases of personnel changes, to disable access to a database.

Note

  • The encryption key you use must be AES-256.
  • To ensure that your Exadata database uses the most current versions of the Vault encryption key, rotate the key from the Database Details page on the Oracle Cloud Infrastructure Console. Do not use the Vault service's Console pages to rotate your Database keys.

If you want to use your own encryption keys to encrypt a database that you create, then you must create a dynamic group and assign specific policies to the group for customer-managed encryption keys. See Managing Dynamic Groups and Let security admins manage vaults, keys, and secrets. Additionally, see To integrate customer-managed key management into Exadata Cloud Service if you need to update customer-managed encryption libraries for the Vault service.

You can also add and remove databases, and perform other management tasks on a database by using command line utilities. For information and instructions on how to use these utilities, see Creating and Managing Exadata Databases Manually.

Database Memory Initialization Parameters

  • When creating a container database, the initialization parameter, SGA_TARGET is set by the automation. This will automatically size the SGA memory pools. The setting will vary depending on the size of the database VM total memory. If the VM has less than or equal to 60 GB of system memory, SGA_TARGET is set to 3800 MB. If the VM has 60 GB or more system memory, SGA_TARGET is set to 7600 MB.
  • The database initialization parameter USE_LARGE_PAGES is set to ONLY upon database creation, which will require the use of large pages for SGA memory. If the VM is configured with insufficient large pages, the instance will fail to start.

Customer-Managed Keys in Exadata Cloud Infrastructure

Customer-managed keys for Exadata Cloud Infrastructure is a feature of Oracle Cloud Infrastructure (OCI) Vault service that enables you to encrypt your data using encryption keys that you control.

The OCI Vault service provides you with centralized key management capabilities that are highly available and durable. This key-management solution also offers secure key storage using isolated partitions (and a lower-cost shared partition option) in FIPS 140-2 Level 3-certified hardware security modules, and integration with select Oracle Cloud Infrastructure services. Use customer-managed keys when you need security governance, regulatory compliance, and homogenous encryption of data, while centrally managing, storing, and monitoring the life cycle of the keys you use to protect your data.

You can:

  • Enable customer-managed keys when you create databases in Exadata Cloud Infrastructure
  • Switch from Oracle-managed keys to customer-managed keys
  • Rotate your keys to maintain security compliance

Requirements

To enable management of customer-managed encryption keys, you must create a policy in the tenancy that allows a particular dynamic group to do so, similar to the following: allow dynamic-group dynamic_group_name to manage keys in tenancy.

Another policy is needed if the Vault being used by the customer is replicated (https://docs.oracle.com/en-us/iaas/Content/KeyManagement/Tasks/replicatingvaults.htm). For vaults that are replicated, this policy is needed: allow dynamic-group dynamic_group_name to read vaults in tenancy

Limitations

To enable Data Guard on Exadata Cloud Infrastructure databases that use customer-managed keys, the primary and standby databases must be in the same realm.

Task 1. Create a Vault and a Master Encryption Key

Create a vault in the Vault service by following the instructions in To create a new vault in Oracle Cloud Infrastructure Documentation. When following these instructions, Oracle recommends that you create the vault in a compartment created specifically to contain the vaults containing customer-managed keys, as described in Before You Begin: Compartment Hierarchy Best Practice.

After creating the vault, create at least one master encryption key in the vault by following the instructions in To create a new master encryption key in Oracle Cloud Infrastructure Documentation. When following these instructions, make these choices:

  • Create in Compartment: Oracle recommends that you create the master encryption key in the same compartment as its vault; that is, the compartment created specifically to contain the vaults containing customer-managed keys.
  • Protection Mode: Choose an appropriate value from the drop-down list:
    • HSM to create a master encryption key that is stored and processed on a hardware security module (HSM).
    • Software to create a master encryption key that is stored in a software file system in the Vault service. Software-protected keys are protected at rest using an HSM-based root key. You may export software keys to other key management devices or to a different OCI cloud region. Unlike HSM keys, software-protected keys are free of cost.
  • Key Shape Algorithm: AES
  • Key Shape Length: 256 bits

Oracle strongly recommends that you create a separate master encryption key for each of your container databases (CDBs). Doing so makes management of key rotation over time much simpler.

Task 2. Create a Service Gateway, a Route Rule, and an Egress Security Rule

Create a service gateway in the VCN (Virtual Cloud Network) where your Oracle Exadata Database Service on Dedicated Infrastructure resources reside by following the instructions in Task 1: Create the service gateway in Oracle Cloud Infrastructure Documentation.

After creating the service gateway, add a route rule and an egress security rule to each subnet (in the VCN) where Oracle Exadata Database Service on Dedicated Infrastructure resources reside so that these resources can use the gateway to access the Vault service:

  1. Go to the Subnet Details page for the subnet.
  2. In the Subnet Information tab, click the name of the subnet's Route Table to display its Route Table Details page.
  3. In the table of existing Route Rules, check whether there is already a rule with the following characteristics:
    • Destination: All IAD Services In Oracle Services Network
    • Target Type: Service Gateway
    • Target: The name of the service gateway you just created in the VCN

    If such a rule does not exist, click Add Route Rules and add a route rule with these characteristics.

  4. Return to the Subnet Details page for the subnet.
  5. In the subnet's Security Lists table, click the name of the subnet's security list to display its Security List Details page.
  6. In the side menu, under Resources, click Egress Rules.
  7. In the table of existing Egress Rules, check whether there is already a rule with the following characteristics:
    • Stateless: No
    • Destination: All IAD Services In Oracle Services Network
    • IP Protocol: TCP
    • Source Port Range: All
    • Destination Port Range: 443

    If such a rule does not exist, click Add Egress Rules and add an egress rule with these characteristics.

Task 3. Create a Dynamic Group and a Policy Statement

To grant your Oracle Exadata Database Service on Dedicated Infrastructure resources permission to access customer-managed keys, you create an IAM dynamic group that identifies these resources and then create an IAM policy that grants this dynamic group access to the master encryption keys you created in the Vault service.

When defining the dynamic group, you identify your Oracle Exadata Database Service on Dedicated Infrastructure resources by specifying the OCID of the compartment containing your Exadata Infrastructure resource.

  1. Copy the OCID of the compartment containing your Exadata Infrastructure resource. You can find this OCID on the Compartment Details page of the compartment.
  2. Create a dynamic group by following the instructions in To create a dynamic group in Oracle Cloud Infrastructure Documentation. When following these instructions, enter a matching rule of this format:
    ALL {resource.compartment.id ='<compartment-ocid>'}

    where <compartment-ocid> is the OCID of the compartment containing your Exadata Infrastructure resource.

After creating the dynamic group, navigate to (or create) an IAM policy in a compartment higher up in your compartment hierarchy than the compartment containing your vaults and keys. Then, add a policy statement of this format:

allow dynamic-group <dynamic-group-name>
to manage keys
in compartment <vaults-and-keys-compartment>
where all {
target.key.id='<key_ocid>',
request.permission!='KEY_DELETE',
request.permission!='KEY_MOVE',
request.permission!='KEY_IMPORT',
request.permission!='KEY_BACKUP’
}

If you are using a replicated virtual private vault for the Oracle Data Guard deployment, add an additional policy statement in this format:

allow dynamic-group <dynamic-group>
to read vaults
in tenancy | compartment <vaults-and-keys-compartment>

where <dynamic-group> is the name of the dynamic group you created and <vaults-and-keys-compartment> is the name of the compartment in which you created your vaults and master encryption keys.

To integrate customer-managed key management into Exadata Cloud Infrastructure

If you choose to encrypt databases in an Exadata Cloud Infrastructure instance using encryption keys that you manage, then you may update the following two packages (using Red Hat Package Manager) to enable DBAASTOOLS to interact with the APIs that customer-managed key management uses.

KMS TDE CLI

To update the KMS TDE CLI package, you must complete the following task on all nodes in the Exadata Cloud Infrastructure instance:

  1. Deinstall current KMS TDE CLI package, as follows:
    rpm -ev kmstdecli
  2. Install the updated KMS TDE CLI package, as follows:
    rpm -ivh kms_tde_cli

LIBKMS

LIBKMS is a library package necessary to synchronize a database with customer-managed key management through PKCS11. When a new version of LIBKMS is installed, any databases converted to customer-managed key management continue to use the previous LIBKMS version, until the database is stopped and restarted.

To update the LIBKMS package, you must complete the following task on all nodes in the Exadata Cloud Infrastructure instance:

  1. Confirm that the LIBKMS package is already installed, as follows:
    rpm -qa --last | grep libkmstdepkcs11
  2. Install a new version of LIBKMS, as follows:
    rpm -ivh libkms
  3. Use SQL*Plus to stop and restart all databases converted to customer-managed key management, as follows:
    shutdown immediate;
startup;
  4. Ensure that all converted databases are using the new LIBKMS version, as follows:
    for pid in $(ps aux | grep "<dbname>" | awk '{print $2;}'); do echo $pid; sudo lsof -p $pid | grep kms | grep "pkcs11_[0-9A-Za-z.]*" | sort -u; done | grep pkcs11
  5. Deinstall LIBKMS packages that are no longer being used by any database, as follows:
    rpm -ev libkms

Using the Console to Manage Databases on Oracle Exadata Database Service on Dedicated Infrastructure

To create or terminate a database, complete procedures using the Oracle Exadata console.

To create a database in an existing Exadata Cloud Infrastructure instance

This topic covers creating your first or subsequent databases.

Note

If IORM is enabled on the Exadata Cloud Infrastructure instance, then the default directive will apply to the new database and system performance might be impacted. Oracle recommends that you review the IORM settings and make applicable adjustments to the configuration after the new database is provisioned.
  1. Open the navigation menu. Click Oracle Database, then click Oracle Exadata Database Service on Dedicated Infrastructure
  2. Choose your Compartment.
  3. Navigate to the cloud VM cluster or DB system you want to create the database in:

    Cloud VM clusters (The New Exadata Cloud Infrastructure Resource Model): Under Oracle Exadata Database Service on Dedicated Infrastructure, click Exadata VM Clusters. In the list of VM clusters, find the VM cluster you want to access and click its highlighted name to view the details page for the cluster.

    DB systems: Under Oracle Base Database, click DB Systems. In the list of DB systems, find the Exadata DB system you want to access, and then click its name to display details about it.

  4. Click Create Database.
  5. In the Create Database dialog, enter the following:
    Note

    You cannot modify the db_name, db_unique_name, and SID prefix after creating the database.
    • Database name: The name for the database. The database name must meet the requirements:
      • Maximum of 8 characters
      • Contain only alphanumeric characters
      • Begin with an alphabetic character
      • Cannot be part of the first 8 characters of a DB_UNIQUE_NAME on the VM cluster
      • DO NOT use the following reserved names: grid, ASM
    • Database unique name suffix:

      Optionally, specify a value for the DB_UNIQUE_NAME database parameter. The value is case insensitive.

      The unique name must meet the requirements:

      • Maximum of 30 characters
      • Contain only alphanumeric or underscore (_) characters
      • Begin with an alphabetic character
      • Unique across the VM cluster. Recommended to be unique across the tenancy.
      If not specified, the system automatically generates a unique name value, as follows: 
      <db_name>_<3_chars_unique_string>_<region-name>
    • Database version: The version of the database. You can mix database versions on the Exadata DB system.
    • Database Home: The Oracle Database Home for the database. Choose the applicable option:
      • Select an existing Database Home: The Database Home display name field allows you to choose the Database Home from the existing homes for the database version you specified. If no Database Home with that version exists, you must create a new one.
      • Create a new Database Home: Use this option to provision a new Database Home for your Data Guard peer database.

        Click Change Database Image to use a desired Oracle-published image or a custom database software image that you have created in advance, then select an Image Type:

        • Oracle Provided Database Software Images:

          then you can use the Display all available version switch to choose from all available PSUs and RUs. The most recent release for each major version is indicated with a latest label.

          Note

          For the Oracle Database major version releases available in Oracle Cloud Infrastructure, images are provided for the current version plus the three most recent older versions (N through N - 3). For example, if an instance is using Oracle Database 19c, and the latest version of 19c offered is 19.8.0.0.0, images available for provisioning are for versions 19.8.0.0.0, 19.7.0.0, 19.6.0.0 and 19.5.0.0.
        • Custom Database Software Images: These images are created by your organization and contain customized configurations of software updates and patches. Use the Select a compartment, Select a region, and Select a Database version selectors to limit the list of custom database software images to a specific compartment, region, or Oracle Database software major release version.

          Region filter defaults to the currently connected region and lists all the software images created in that region. When you choose a different region, the software image list is refreshed to display the software images created in the selected region.

    • PDB name: (Optional) For Oracle Database 12c (12.1.0.2) and later, you can specify the name of the pluggable database. The PDB name must begin with an alphabetic character, and can contain a maximum of eight alphanumeric characters. The only special character permitted is the underscore ( _).

      To avoid potential service name collisions when using Oracle Net Services to connect to the PDB, ensure that the PDB name is unique across the entire VM cluster. If you do not provide the name of the first PDB, then a system-generated name is used.

    • Create administrator credentials: (Read only) A database administrator SYS user will be created with the password you supply.
      • Username: SYS
      • Password: Supply the password for this user. The password must meet the following criteria:

        A strong password for SYS, SYSTEM, TDE wallet, and PDB Admin. The password must be 9 to 30 characters and contain at least two uppercase, two lowercase, two numeric, and two special characters. The special characters must be _, #, or -. The password must not contain the username (SYS, SYSTEM, and so on) or the word "oracle" either in forward or reversed order and regardless of casing.

      • Confirm password: Re-enter the SYS password you specified.
      • Using a TDE wallet password is optional. If you are using customer-managed encryption keys stored in a vault in your tenancy, the TDE wallet password is not applicable to your DB system. Use Show Advanced Options at the end of the Create Database dialog to configure customer-managed keys.

        If you are using customer-managed keys, or if you want to specify a different TDE wallet password, uncheck the Use the administrator password for the TDE wallet box. If you are using customer-managed keys, leave the TDE password fields blank. To set the TDE wallet password manually, enter a password in the Enter TDE wallet password field, and then confirm by entering it into the Confirm TDE wallet password field.

    • Configure database backups: Specify the settings for backing up the database to Autonomous Recovery Service or Object Storage:
      • Enable automatic backup: Check the check box to enable automatic incremental backups for this database. If you are creating a database in a security zone compartment, you must enable automatic backups.
      • Backup Destination: Your choices are Autonomous Recovery Service or Object Storage.
      • Backup Scheduling:
        • Object Storage (L0):
          • Full backup scheduling day: Choose a day of the week for the initial and future L0 backups to start.
          • Full backup scheduling time (UTC): Specify the time window when the full backups start when the automatic backup capability is selected.

          • Take the first backup immediately: A full backup is an operating system backup of all datafiles and the control file that constitute an Oracle Database. A full backup should also include the parameter file(s) associated with the database. You can take a full database backup when the database is shut down or while the database is open. You should not normally take a full backup after an instance failure or other unusual circumstances.

            If you choose to defer the first full backup your database may not be recoverable in the event of a database failure.

        • Object Storage (L1):
          • Incremental backup scheduling time (UTC): Specify the time window when the incremental backups start when the automatic backup capability is selected.
        • Autonomous Recovery Service (L0):
          • Scheduled day for initial backup: Choose a day of the week for the initial backup.
          • Scheduled time for initial backup (UTC): Select the time window for the initial backup.

          • Take the first backup immediately: A full backup is an operating system backup of all datafiles and the control file that constitute an Oracle Database. A full backup should also include the parameter file(s) associated with the database. You can take a full database backup when the database is shut down or while the database is open. You should not normally take a full backup after an instance failure or other unusual circumstances.

            If you choose to defer the first full backup your database may not be recoverable in the event of a database failure.

        • Autonomous Recovery Service (L1):
          • Scheduled time for daily backup (UTC): Specify the time window when the incremental backups start when the automatic backup capability is selected.
      • Deletion options after database termination: Options that you can use to retain protected database backups after the database is terminated. These options can also help restore the database from backups in case of accidental or malicious damage to the database.
        • Retain backups for the period specified in your protection policy or backup retention period: Select this option if you want to retain database backups for the entire period defined in the Object Storage Backup retention period or Autonomous Recovery Service protection policy after the database is terminated.
        • Retain backups for 72 hours, then delete: Select this option to retain backups for a period of 72 hours after you terminate the database.

      • Backup Retention Period/Protection Policy: If you choose to enable automatic backups, you can choose a policy with one of the following preset retention periods, or a Custom policy.

        Object Storage Backup retention period: 7, 15, 30, 45, 60. Default: 30 days. The system automatically deletes your incremental backups at the end of your chosen retention period.

        Autonomous Recovery Service protection policy:

        • Bronze: 14 days
        • Silver: 35 days
        • Gold: 65 days
        • Platinum: 95 days
        • Custom defined by you
        • Default: Silver - 35 days
      • Enable Real-Time Data Protection: Real-time protection is the continuous transfer of redo changes from a protected database to Autonomous Recovery Service. This reduces data loss and provides a recovery point objective (RPO) near 0. This is an extra cost option.

  6. Click Show Advanced Options to specify advanced options for the database:

    • Management:

      Oracle SID prefix: The Oracle Database instance number is automatically added to the SID prefix to create the INSTANCE_NAME database parameter. The INSTANCE_NAME parameter is also known as the SID. The SID is unique across the cloud VM Cluster. If not specified, SID prefix defaults to the db_name.

      Note

      Entering an SID prefix is only available for Oracle 12.1 databases and above.

      The SID prefix must meet the requirements:

      • Maximum of 12 characters
      • Contain only alphanumeric characters. You can, however, use underscore (_), which is the only special character that is not restricted by this naming convention.
      • Begin with an alphabetic character
      • Unique in the VM cluster
      • DO NOT use the following reserved names: grid, ASM
    • Character set: The character set for the database. The default is AL32UTF8.
    • National character set: The national character set for the database. The default is AL16UTF16.

    • Encryption:

      If you are creating a database in an Exadata Cloud Service VM Cluster, then you can choose to use encryption based on encryption keys that you manage. By default, the database is configured using Oracle-managed encryption keys. To configure the database with encryption based on encryption keys you manage:

      1. Select Use customer-managed keys. You must have a valid encryption key in Oracle Cloud Infrastructure Vault service. See Let security admins manage vaults, keys, and secrets.
        Note

        You must use AES-256 encryption keys for your database.
      2. Choose a Vault.
      3. Select a Master encryption key.
      4. To specify a key version other than the latest version of the selected key, check Choose the key version and enter the OCID of the key you want to use in the Key version OCID field.
      Note

      The Key version will only be assigned to the container database (CDB), and not to its pluggable database (PDB). PDB will be assigned an automatically generated new key version.
    • Tags: If you have permissions to create a resource, then you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, see Resource Tags . If you are not sure whether to apply tags, skip this option (you can apply tags later) or ask your administrator.
  7. Click Create Database.

After database creation is complete, the status changes from Provisioning to Available, and on the database details page for the new database, the Encryption section displays the encryption key name and the encryption key OCID.

WARNING:

Do not delete the encryption key from the vault. This causes any database protected by the key to become unavailable.

To move a database to another Database Home

This task explains how to patch a single Oracle Database in your Exadata Cloud Infrastructure instance by moving it to another Database Home.

You can move a database to any Database Home that meets at either of the following criteria:

  • The target Database Home uses the same Oracle Database software version (including patch updates) as the source Database Home
  • The target Database Home is based on either the latest version of the Oracle Database software release used by the database, or one of the three prior versions of the release

Moving a database to a new Database Home brings the database up to the patch level of the target Database Home. For information on patching Database Homes, see Database Home Patching and .

  1. Open the navigation menu. Click Oracle Database, then click Oracle Exadata Database Service on Dedicated Infrastructure
  2. Choose your Compartment.
  3. Navigate to the database you want to move.:

    Cloud VM clusters ( The New Exadata Cloud Infrastructure Resource Model ): Under Oracle Exadata Database Service on Dedicated Infrastructure, click Exadata VM Clusters. In the list of VM clusters, click the name of the VM cluster that contains the database you wan to move.

    DB systems: Under Bare Metal, VM, and Exadata, click DB Systems. In the list of DB systems, find you want to access, and then click the name of the Exadata DB system that contains the database you want to move..

  4. Click More Actions, then click Move to Another Home.
  5. Select the target Database Home.
  6. Click Move Database.

  7. Confirm the move operation.

    The database is moved in a rolling fashion. The database instance will be stopped, node by node, in the current home and then restarted in the destination home. While the database is being moved, the Database Home status displays as Moving Databse. When the operation completes, Database Home is updated with the current home. Datapatch is executed automatically, as part of the database move, to complete post-patch SQL actions for all patches, including one-offs, on the new Database Home. If the database move operation is unsuccessful, then the status of the database displays as Failed, and the Database Home field provides information about the reason for the failure.

To terminate a database

You'll get the chance to back up the database prior to terminating it. This creates a standalone backup that can be used to create a database later. We recommend that you create this final backup for any production (non-test) database.

Note

Terminating a database removes all automatic incremental backups of the database from Oracle Cloud Infrastructure Object Storage. However, all full backups that were created on demand, including your final backup, will persist as standalone backups.

You cannot terminate a database that is assuming the primary role in a Data Guard association. To terminate it, you can switch it over to the standby role.

  1. Open the navigation menu. Click Oracle Database, then click Oracle Exadata Database Service on Dedicated Infrastructure
  2. Choose your Compartment.

  3. Navigate to the database:

    Cloud VM clusters (The New Exadata Cloud Infrastructure Resource Model): Under Oracle Exadata Database Service on Dedicated Infrastructure, click Exadata VM Clusters. In the list of VM clusters, find the VM cluster you want to access and click its highlighted name to view the details page for the cluster.

    DB systems: Under Oracle Base Database, click DB Systems. In the list of DB systems, find the Exadata DB system you want to access, and then click its name to display details about it.

    On the cloud VM cluster or DB system details page, in the Databases table, click the name of the database to display the Database Details page.
  4. Click More Actions, and then click Terminate.

    • Configure automatic backups as needed.
    • Type the name of the database to confirm the termination
  5. Click Terminate Database.

    The database's status indicates Terminating.

    Note

    The database stays in a terminated state with backups listed until all backups are expired.
To administer Vault encryption keys

Use this procedure to rotate the Vault encryption key or or change the encryption management configuration.

After you provision a database in an Exadata DB system or cloud VM cluster, you can rotate the Vault encryption key or change the encryption management configuration for that database.

Note

  • To ensure that your Exadata database uses the most current version of the Vault encryption key, rotate the key from the database details page on the Oracle Cloud Infrastructure Console. Do not use the Vault service.
  • You can rotate Vault encryption keys only on databases that are configured with customer-managed keys.
  • You can change encryption key management from Oracle-managed keys to customer-managed keys but you cannot change from customer-managed keys to Oracle-managed keys.
  • Oracle supports administering encryption keys on databases after Oracle Database 11g release 2 (11.2.0.4).
  1. Open the navigation menu. Click Oracle Database, then click Oracle Exadata Database Service on Dedicated Infrastructure
  2. Choose your compartment from the Compartment drop-down.

Using the API to manage Databases

For information about using the API and signing requests, see REST APIs and Security Credentials. For information about SDKs, see Software Development Kits and Command Line Interface.

Use these API operations to manage databases.

For the complete list of APIs for the Database service, see Database Service API.

Create and Manage Exadata Pluggable Databases

You can create and manage pluggable databases (PDBs) in Exadata Cloud Infrastructure using the Console and APIs.

In this documentation, "database" refers to a container database, also called a CDB. For more information on these resource types, see Multitenant Architecture in the Oracle Database documentation. See Provisioning and Managing Exadata Databases for information on container databases in Exadata Cloud Infrastructure.

Oracle 19c or later databases created in Exadata Cloud Infrastructure include an initial PDB that you can access from the Database Details page in the Console. You can create and manage additional PDBs in the database using the Console or APIs.

  • Backup

    You can take a backup of the PDB optionally during create, clone, or relocate operations when the CDB is configured with the auto-backup feature. The PDB backup destination will always be the same as CDB, and the backups cannot be accessed directly or created on demand. Oracle recommends immediately backing up the PDB after you create or clone it. This is because the PDB will not be recoverable until the next daily auto-backup completes successfully, leading to a possible data loss.

  • Restore
    • Base Database Service / Oracle Exadata Database Service on Dedicated Infrastructure:
      • In place restore: You can restore a PDB within the same CDB to last known good state or to a specified timestamp.
      • Out of place restore: You can restore a PDB by creating a database (CDB) from the backup, then selecting a PDB or a subset of them you want to restore on the new database.
    • Oracle Exadata Database Service on Cloud@Customer:
      • In place restore: You can restore a PDB within the same CDB to last known good state and specified timestamp.
      • Out of place restore: It's not available.

      You can perform an in-place restore when you want to move a PDB back to a specified state or time. Both the CDB and PDB must be up and running and only one PDB can be restored at a time.

      • If you have multiple PDBs in your CDB and want to restore multiple of them to the same CDB, then you could restore each individual PDB, one PDB at a time, from the CDB backup.
      • When the CDB is down, you could restore the complete CDB and all the PDBs in that CDB will also be restored.
      • You could either restore the database to the specified timestamp or to its last known good state.
  • Relocate
    You can relocate a PDB from one CDB to another CDB within the same availability domain (AD):
    • Across compartments, VM clusters, DB system (for BaseDB only), or VCNs (not applicable to ExaDB-C@C). If two different VCNs are used, then both VCNs must be peered before relocating.
    • To the same or a higher database version.

    During relocate, the PDB will be removed from the source CDB and moved to the destination CDB that is up and running. In a Data Guard association, a PDB relocated to the primary will be synchronized with the standby as well.

  • Clone

    A clone is an independent and complete copy of the given database as it existed at the time of the cloning operation. You can create clones of your PDB within the same CDB or a different CDB and refresh the cloned PDB.

    The following types of clones are supported:
    • Local clone: A copy of the PDB is created within the same CDB.
    • Remote clone: A copy of the PDB is created in a different CDB.
    You can perform a remote clone of a PDB from one CDB to another CDB within the same availability domain (AD):
    • Across compartments, VM clusters, DB system (for BaseDB only), or VCNs (not applicable to ExaDB-C@C). If two different VCNs are used, then both VCNs must be peered before cloning.
    • To the same or a higher database version.
    • Refreshable clone: A copy of the PDB is created in a different CDB, and you will be able to refresh the cloned PDB.
      You can perform a refreshable clone of a PDB from one CDB to another CDB within the same availability domain (AD):
      • Across compartments, VM clusters, DB system (for BaseDB only), or VCNs (not applicable to ExaDB-C@C). If two different VCNs are used, then both VCNs must be peered before cloning.
      • To the same or a higher database version.
  • Refreshable Clone
    A refreshable clone enables you to keep your remote clone updated with the source PDB. You can only refresh while the PDB is in mount mode. The only open mode you can have is read-only and refresh cannot be done while it is in read-only mode.
    • A database link user credential is required for creating a refreshable clone.
    • Clone, relocate, and in-place restore operations are not supported in the refreshable clone. Relocate and in-place restore operations are not supported in the source, and the source can only be deleted after disconnecting or deleting the refreshable clone.
    • In a Data Guard association, a refreshable clone cannot be created on standby, but it can be created on the primary. However, the primary will not be synced to the standby.
      Note

      A PDB in standby cannot be used as the source for a refreshable PDB.
  • Convert Refreshable PDB to Regular PDB

    You can convert a refreshable PDB to a regular PDB by disconnecting the refreshable clone (destination PDB) from the source PDB at any time. If the refresh PDB is in a Data Guard association, when it is converted to a regular PDB the PDB will be synced to the standby as part of the conversion process.

  • Open Modes

    On the Console, you can see the open modes of a PDB, such as read-write, read-only, and mounted. If the PDB status is the same across all nodes, the system displays the same status for all PDBs. If the PDB statuses are different across the nodes, the system displays a message indicating on which nodes the PDBs are opened in read-write mode. You cannot change the open mode of a PDB through the API or Console. However, you can start or stop a PDB. Starting the PDB will start it in read-write mode. Stopping the PDB will close it and it will remain in mount mode.

Parent topic: Manage Databases on Exadata Cloud Infrastructure

Limitations for Pluggable Database Management

  • New PDBs created with SQL are not immediately discovered by OCI's control plane and displayed in the Console. However, OCI does perform a sync operation on a regular basis to discover manually-created PDBs, and they should be visible in the Console and with API-based tools within 45 minutes of creation. Oracle recommends using the Console or API-based tools (including the OCI CLI , SDKs, and Terraform) to create PDBs.
  • Pluggable database operations are supported only for databases using Oracle Database 19c and later.
  • PDBs are backed up at the CDB level when using the OCI Console or APIs, and each backup includes all the PDBs in the database. However, the dbaascli utility's dbaascli database backup command allows you to create backups of specified PDBs. See Using the dbaascli Utility on Exadata Cloud Infrastructure for more information.
  • Restore operations are performed at the CDB level when using the OCI Console or APIs. However, the dbaascli utility's dbaascli pdb recover command allows you to restore backups of specified PDBs. See Using the dbaascli Utility on Exadata Cloud Infrastructure for more information.

Creating an Exadata Pluggable Database

You can create a pluggable database (PDB) in Exadata Cloud Service from the OCI Console, or with the APIs and API-based tools (the OCI CLI, SDKs, and Terraform). PDBs must be created one at a time. During the PDB create operation, the parent database (CDB) is in the "Updating" state. Creating a new PDB has no impact on existing PDBs in the database.

        Note

        When you create a new PDB, a local user in the PDB is created as the administrator and granted the PDB_DBA role locally to the administrator.
        To reset the password:
        1. Connect to the container where your PDB exists using the SQL*Plus CONNECT statement.
          SQL> show con_name;
CON_NAME
------------------------
CDB$ROOT

          For more information, see Administering a CDB and Administering PDBs in the Oracle® Multitenant Administrator’s Guide.

        2. Find the administrator name of your PDB:
          SQL> select grantee from cdb_role_privs where con_id = (select con_id from cdb_pdbs where pdb_name = '<PDB_NAME>') and granted_role = 'PDB_DBA';
        3. Switch into your PDB:
          SQL> alter session set container=<PDB_NAME>;
Session altered.
SQL> show con_name;
CON_NAME
------------------------
<PDB_NAME>
        4. Reset the PDB administrator password:
          SQL> alter user <PDB_Admin> identified by <PASSWORD>;
User altered.
    • Source database SYS password: Enter the database admin password.
    • Database link: Enter the user name and password for the database link. Note that the user must be precreated in the source database. The DB link will be created in the destination using that username and password.
    • Take a backup of the PDB immediately after creating it: You must enable auto-backup on the CDB to back up a PDB immediately after creating it. This check box is checked by default if auto-backup was enabled on the CDB.
      Note

      If the checkbox is unchecked, the system displays a warning stating that PDB cannot be recovered until the next daily backup has been successfully completed.
    • Advanced Options:
      • Tags: Optionally, you can apply tags. If you have permission to create a resource, you also have permission to apply free-form tags to that resource. To apply a defined tag, you must have permission to use the tag namespace. For more information about tagging, see Resource Tags. If you are not sure if you should apply tags, skip this option (you can apply tags later) or ask your administrator.
  7. Click Relocate pluggable database.
    Note

    Relocate will incur downtime during the process and that the time required is based on the size of the PDB.

    Click the Change Compartment hyperlink to choose your compartment.

  5. Configure Database Home: Select an existing Database Home or create one as applicable. Note that this field is not available when you create a Database from the Database Home details page.
    • Select an existing Database Home: If one or more Database Homes already exist for the database version you have selected, then this option is selected by default. And, you will be presented with a list of Database Homes. Select a Database Home from the list.
    • Create a new Database Home: If no Database Homes exist for the database version you have selected, then this option is selected by default.
      1. Enter Database Home display name.
      2. Click Change Database Image to select your software version.

        Select a Database Software Image window is displayed.

      3. Select an Image Type, Oracle Provided Database Software Images, or Custom Database Software Images.

        If you choose Oracle Provided Database Software Images, then you can use the Display all available version switch to choose from all available PSUs and RUs. The most recent release for each major version is indicated with a latest label.

        Note

        For the Oracle Database major version releases available in Oracle Cloud Infrastructure, images are provided for the current version plus the three most recent older versions (N through N - 3). For example, if an instance is using Oracle Database 19c, and the latest version of 19c offered is 19.8.0.0.0, images available for provisioning are for versions 19.8.0.0.0, 19.7.0.0, 19.6.0.0 and 19.5.0.0.

  6. Provide the database name: Specify a user-friendly name that you can use to identify the database. The database name must contain only the permitted characters.

    Review the following guidelines when selecting a database name.
    • maximum of 8 characters
    • contain only alphanumeric characters
    • begin with an alphabetic character
    • cannot be part of first 8 characters of a db_unique_name on the VM cluster
    • unique within a VM cluster
    • DO NOT use grid because grid is a reserved name
    • DO NOT use ASM because ASM is a reserved name

  7. Provide a unique name for the database: Optionally, specify a unique name for the database. This attribute defines the value of the db_unique_name database parameter. The value is case insensitive.

    The db_unique_name must contain only the permitted characters. Review the following guidelines when selecting a database name.

    • maximum of 30 characters
    • can contain alphanumeric and underscore (_) characters
    • begin with an alphabetic character
    • unique across the fleet/tenancy

    If a unique name is not provided, then the db_unique_name defaults to the following format <db_name>_<3 char unique string>_<region-name>.

    If you plan to configure the database for backup to a Recovery Appliance backup destination, then the unique database name must match the name that is configured in the Recovery Appliance.

  8. Provide the administration password: Provide and confirm the Oracle Database administration password. This password is used for administration accounts and functions in the database, including:

    • The password for the Oracle Database SYS and SYSTEM users.
    • The Transparent Data Encryption (TDE) Keystore password.

    For Oracle Database 12c Release 1 or later releases, the password for the PDB administration user in the first PDB (PDBADMIN) must be nine to 30 characters and contain at least two uppercase, two lowercase, two numeric, and two special characters. The special characters must be _, #, or -. In addition, the password must not contain the name of the tenancy or any reserved words, such as Oracle or Table, regardless of casing.

  9. Enter the source database's TDE wallet or RMAN password: Password must match the TDE wallet or RMAN password of the source database contained in the backup.
  10. Click Create Backup.

Changing the Database Passwords

To change the SYS password, or to change the TDE wallet password, use this procedure.

The password that you specify in the Database Admin Password field when you create a new Exadata Cloud Infrastructure instance or database is set as the password for the SYS, SYSTEM, TDE wallet, and PDB administrator credentials. Use the following procedures if you need to change passwords for an existing database.

Note

if you are enabling Data Guard for a database, then the SYS password and the TDE wallet password of the primary and standby databases must all be the same.
Note

Using the dbaascli to change the SYS password will ensure the backup/restore automation can parallelize channels across all nodes in the cluster.

To Change the SYS Password for an Exadata Cloud Infrastructure Database

  1. Log onto the Exadata Cloud Infrastructure virtual machine as opc.
  2. Run the following command:
    sudo dbaascli database changepassword --dbname database_name --user SYS

To Change Database Passwords in a Data Guard Environment

  1. Run the following command on the primary database:
    dbaascli database changePassword —dbName <dbname> --user SYS --prepareStandbyBlob true --blobLocation <location to create the blob file>
  2. Copy the blob file created to all the standby databases and update the file ownership to oracle user.
  3. Run the following command on all the standby databases:
    dbaascli database changePassword —dbName <dbname> --user SYS --standbyBlobFromPrimary <location of copies the blob file>

To Change the TDE Wallet Password for an Exadata Cloud Infrastructure Database

  1. Log onto the Exadata Cloud Infrastructure virtual machine as opc.
  2. Run the following command:
    sudo dbaascli tde changepassword --dbname database_name
