8 Identifying Host for Enterprise Manager Cloud Control


Note:

Follow these instructions only if you are upgrading using the 2-System upgrade approach or the 1-System upgrade aproach on a different host. Perform these steps in the Enterprise Manager Grid Control console of the earlier release.

To identify and provide information about the host where you plan to install Enterprise Manager Cloud Control, 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.

    • 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 Identify Host and Port for New Enterprise Manager System.

  5. On the Identify Host and Port for New Enterprise Manager System page, enter the following:

    • The fully qualified name of the host where you plan to install Enterprise Manager Cloud Control. For example, example.com.

    • The secure port and the unsecure upload port you plan to assign for that Enterprise Manager Cloud Control console. For example, 1768.

      In case of a multi-OMS environment, if the host on which you plan to install Oracle Management Service 12c is managed by a Server Load Balancer (SLB), then select Click if you wish to have Server Load Balancer (SLB) configured for your Oracle Management Service 12c Release 1 (12.1.0.1.0). Then, enter the fully qualified name, and the secure and unsecure upload ports of the host where the SLB is running.


    Note:

    • For 2-System upgrade approach and 1-System upgrade approach on a different host, understandably, the host referred to here is any host other than the one where your existing OMS is running. In a Multi-OMS environment this means that a new virtual host name must be used and a new SLB configuration created for this virtual host name.

    • Ensure that you install Oracle Management Service 12c on the host entered here, and ensure that you use the same HTTPS and HTTP upload ports entered here. In the installation wizard, on the Port Configuration Details screen, enter the HTTPS upload port for the component Enterprise Manager Upload Http SSL Port, and the HTTP upload port for the component Enterprise Manager Upload Http Port.

      If you have already installed Oracle Management Service 12c, then retrieve the values from the emgc.properties file, which is available in the OMS home. For HTTPS upload port, look for the value assigned to the parameter EM_UPLOAD_HTTPS_PORT, and for HTTP upload port, look for the value assigned to the parameter EM_UPLOAD_HTTP_PORT.

    • Once you enter the secure and unsecure upload ports here, avoid changing them once the deployment starts.


  6. In the Configure Postupgrade Tasks section, select one of the following options:

    • Disable automatic DDMP jobs, if you want to prevent the DDMP jobs from running automatically. This option is applicable for 1-System upgrade approach as well as 1-System upgrade approach on a different host.

      If you want to run the DDMP jobs explicitly after upgrading to Enterprise Manager Cloud Control, perform Step (3) as described in Tracking the Status of Deferred Data Migration Jobs—select each component and click Start.


      Note:

      If you disable the DDMP jobs, the ADMP jobs are also disabled by default.

    • Disable automatic ADMP jobs, if you want to prevent the ADMP jobs from running automatically. This option is applicable only for 1-System upgrade approach.

      If you want to run the DDMP jobs explicitly after upgrading to Enterprise Manager Cloud Control, perform Step (3) as described in Tracking the Status of Accrued Data Migration Jobs.

  7. Click Save.

    Enterprise Manager Grid Control saves the information you provided and returns to the Upgrade Console page that shows a list of tasks to perform for the upgrade approach you selected.
