9 Managing Software


Note:

Perform these steps in the Enterprise Manager Grid Control console of the earlier release.

To manage information about the location of the core Management Agent software and its associated plug-ins, follow these steps:

  1. In Grid Control, click Deployments.

  2. On the Deployments page, in the Upgrade section, click Enterprise Manager 12c Upgrade Console.

  3. On the Upgrade Console page, in the Select Upgrade Type section, select one of the following. For information about these upgrade approaches, see "Understanding Upgrade Approaches".

    • To upgrade your Enterprise Manager system with downtime (even if you manually install Management Agents), select 1-System.

    • To upgrade your Enterprise Manager system with "near zero" downtime (even if you manually install Management Agents), select 2-System.

    • To upgrade your Enterprise Manager system with downtime on a different host, select 1-System on a Different Host.

    Enterprise Manager Grid Control refreshes the page and displays a table with a list of tasks you need to perform for the upgrade approach you selected.

  4. In the Preupgrade Steps section, from the table, click Manage Software.

  5. On the Manage Software page, in the Agent Upgradability and Target Upgradability pie charts, click the hyperlinks in the respective legends and identify the Management Agents and targets that can be upgraded, and that cannot be upgraded due to unavailability of the Management Agent software or the plug-in software.

  6. In the Provide Software Location section, enter the absolute path to the directory where the core Management Agent software and the plug-in software are present for the required platforms.

    For example, /john/software/oracle/em/.

    And then, click Validate to register that location with the Enterprise Manager system.


    Note:

    • The absolute path you enter must be to a staging location that contains both the Management Agent software and the plug-in software.

      To download the Management Agent software and the plug-ins, follow these steps

      (a) Access the following URL:

      http://www.oracle.com/technetwork/oem/grid-control/downloads/oem-upgrade-console-502238.html

      (b) Download the Management Agent software to an accessible location. Do NOT extract the contents of the software ZIP file. The Management Agent software is platform-specific, so ensure that you copy the software for the platform on which you want to install.

      (c) Download all the required plug-ins to the same location. Plug-ins are generic, so they are common for all platforms.

      Ensure that you download all the plug-ins listed as required plug-ins on the Manage page, whether or not you want to monitor a target with them. You may feel that a few plug-ins are not required because you do not have targets to be monitored by them, but those plug-ins may be required for upgrading your system. Therefore, download all the plug-ins listed on the Manage Software page. Ensure that you download these plug-ins before backing up the database that contains the Management Repository.

    • After registering the locations of the Management Agent software and the plug-in software, if you download some more plug-ins at a later stage in the same or a different location, then register the location of those recently downloaded plug-ins as well.

    • The validation and registration process might take some time to complete, so after you click Validate, wait for some time for the process to end. Once the process ends, you should see a message confirming that the location has been successfully registered.

    • If you plan to install multiple Oracle Management Services (OMSes), then ensure that the location you enter is writable and accessible to all the OMSes.
