Creating a Configuration

Create an OCI Database with PostgreSQL database system configuration.

Important

OCI Database with PostgreSQL provides optimized default configurations out of the box targeting a specific shape. Only advanced users might need to change and manage them. For more information, see PostgreSQL reference manual.

When creating a configuration, select either a fixed configuration or a flexible configuration.

A fixed configuration is associated with specific hardware details, and can only be applied to database systems with hardware configurations where OCPU and memory exactly match those details.

A flexible configuration can be applied to database systems with differing hardware configurations. If a database system uses a flexible configuration, you can update its hardware configuration without the need to change configurations. Flexible configurations let you use integer expressions for some variable values. For more information, see Flexible Configurations and Integer Variables.

    1. Open the navigation menu and click Databases. Under PostgreSQL, click Configurations.
    2. (Optional) In the List scope section, under Compartment, select a compartment.
    3. Click Create configuration.
    4. In the Create configuration window, provide values for the following:
      • Name: Enter a name for the configuration list. Avoid entering confidential information.
      • Description: Enter a description for the configuration list.
      • Configuration shape type: Select either Flex or Fixed. Flexible configurations can be applied to database systems with varying shapes and hardware configurations. A fixed configuration can only be applied to a database system with a specific, fixed shape and matching hardware configuration. For more information, see Supported Shapes.
    5. In the Configure placement and hardware section, provide values for the following:
      • Select a compartment: Select the compartment to contain the configuration.
      • Shape series: Select a processor group.
        • AMD: (Flexible) Standard shapes that use current-generation AMD processors.
        • Intel: (Flexible) Standard shapes that use current-generation Intel processors.
      • Shape name: If using a fixed shape, select the shape of database system that this configuration list can be applied to.
    6. In the User variables (read/write) section, provide the following:
      • Variable name: Select a variable from the list.
      • Variable value: Select or enter a value for the variable.
      Tip

      If the configuration supports flexible shapes, you can use integer expressions for some values. For more information, see Flexible Configurations and Integer Variables.
    7. (Optional) Click + Another variable to add another variable to the configuration list.
    8. Click Create.

  • Use the oci psql configuration create command and required parameters to create a configuration:

    oci psql configuration create --compartment-id <compartment_OCID> [OPTIONS]

    For a complete list of parameters and values for CLI commands, see the CLI Command Reference.

  • Run the CreateConfiguration operation to create a configuration.
