Remove a Java Runtime

You can delete Java runtimes from a fleet as part of your fleet maintenance.

Note

  • Deletion of Java runtimes belonging to versions JDK 1.3 and earlier will be on a best-effort basis and isn't guaranteed to succeed.
  • The delete operation removes the entire JDK or JRE folder when you delete a Java runtime. Back up any files that you need to keep before you start the delete process.
  • Delete Java runtimes summary window displays applications that were launched during the time-frame selected. There could be running applications still using the runtime at the time of initiating a delete operation.
Follow either of the steps to delete a Java runtime:
  1. Select one or more Java runtime from the Java runtimes table.

    The Delete button is enabled only if one or more eligible runtimes are selected. Checkboxes aren't enabled for OpenJDK runtimes.

    1. Click Delete and the Delete Java runtimes summary window opens. You'll see a message with an archives link to the Oracle Java Runtime Download. You'll also see a Summary table that lists the affected resources, including:
      • Applications: By default, it's sorted by applications, so that the runtimes are presented in the order of least invoked to most invoked in the timeframe selected.
      • Runtime version: Click to open the Details page in a new window.
      • Managed Instances
      • Installations
    2. If you don't want to proceed with the delete operation, click the Cancel button.
    3. Click Delete to proceed with the deletion of the selected runtimes. A work request will be created by JMS for this operation. The progress or status of the operation can be viewed from the Work Request module.
  2. Click Managed instances panel.
    1. Select the required managed instance.
    2. In the Java runtimes installations table, select the Java runtime paths and click Delete.
    3. In the Delete Java runtime installations panel, review the Summary and click Delete.
