23 Reconfiguring Oracle Software Library


Note:

Follow these instructions only if you are upgrading using the 2-System upgrade approach.

To reconfigure an upgraded Software Library in a two-system upgrade, perform these steps:


Note:

  • In a one-system upgrade, where the upgraded Enterprise Manager 12c comes up on the same host, reconfiguration is not required as the upgraded Software Library becomes functional when the system starts.

    For a one system upgrade, where the upgraded Enterprise Manager 12c comes up on a different host, all the location(s) configured in the earlier, existing Enterprise Manager system for Software Library should be accessible from the new host.

  • In a two-system upgrade, and sometime in a one-system upgrade on a different host, if the location configured in the earlier, existing Enterprise Manager system is a local file system path, then follow the instructions outlined in the chapter "Upgrading with 1-System Upgrade Approach" for more information.


  1. In Cloud Control, from Setup menu, select Provisioning and Patching and then, click Software Library.

  2. If the Software Library has been upgraded, then on the Software Library home page, the following notification will appear:

    Software Library has been upgraded recently and has not been reconfigured yet. Software Library will be usable only after the reconfiguration has been performed. To initiate the reconfiguration process, click Post Upgrade Reconfiguration.

    Click Post Upgrade Reconfiguration, to reconfigure the Software Library.

  3. On the Software Library Reconfigure Locations page, enter the new file system location that is to be configured, corresponding to the location configured in the earlier, existing Enterprise Manager system.

    Surrounding text describes reconfig_page.gif.

    The archive of the location which was configured for the old Enterprise Manager system must be unzipped in the corresponding location on the new file system. Also, ensure that the new location, and all its unarchived files and directories have read/write permissions for the 12c OMS process owner.

    For example:

    In the earlier, existing Enterprise Manager system, lets assume that the Software Library was configured to use the following file system locations:

    /shared/swlib1
    /shared/swlib2
    

    Figure 23-1 Two-System Reconfiguration

    2-System Reconfiguration

    After an upgrade, on the Reconfigure Locations page, you will see:

    migrated1, /shared/swlib1
    migrated2, /shared/swlib2
    

    where, migrated1 and migrated2 are names automatically assigned to the upgraded locations.


    Note:

    Since the new locations are only reconfiguring the OMS Shared File System storage locations, you must ensure that these new locations are either NFS-mounted shared locations or OCFS2 shared locations.

    You should then provide an alternate file system path for each of the existing locations. For example, as follows:

    migrated1, /shared/swlib1, /vol/newswlib1
    migrated2, /shared/swlib2, /vol/newswlib2
    

    Before confirming this configuration, you must ensure that the new locations have the corresponding back ups of the configured Software Library directories unarchived, which means, /vol/newswlib1 should have the same content as /shared/swlib1, /vol/newswlib2 should have the same content as /shared/swlib2 had when the backup was taken.

    1. Click Validate to submit a validation job that performs exhaustive validation checks on the entities being migrated. Ensure that you track this job to completion. If there are any validation errors, then it will appear on the job step. Some of the common validation errors are:

      - The new location specified for reconfiguration does not exist.

      - The new location specified for reconfiguration does not have read/write permissions for the OMS process owner.

      - The content of the location(s) configured in the old Enterprise Manager Software Library is not restored in the corresponding new location specified for reconfiguration.

    2. After a successful validation, click Confirm to reconfigure the Software Library. A job is submitted which must be tracked to successful completion, following which you should initiate any patching or provisioning tasks.
