D Installing Additional Oracle Management Service in Silent Mode

Oracle recommends you to use the Add Management Service deployment procedure to install an additional Oracle Management Service (OMS). For instructions, refer to Oracle Enterprise Manager Cloud Control Basic Installation Guide.

However, if you have any security restrictions or audit demands in your environment, or if you are not permitted to use Oracle credentials to log in over the network for installation, then follow these steps to manually install an additional OMS in silent, non-interactive mode.

1. If Oracle Software Library is configured on the main OMS, then ensure that it is accessible from the remote host where you plan to install the additional OMS.

   For easy understanding, the main OMS is referred to as primary OMS, and the second OMS you are about to install is referred to as additional OMS in this procedure.

2. On the remote host, perform a software-only installation of the additional OMS as described in Installing in Graphical Mode. Ensure that you install the software binaries in the same middleware location as that of the primary OMS.

3. On the additional OMS, apply all the patches you applied on the primary OMS so that both OMSes are identical and are in sync.

   To identify the patches you applied on the primary OMS, run the following commands from its Oracle home:

   $<OMS_HOME>/OPatch/opatch lsinventory

4. Export the configuration details from the primary OMS. To do so, run the following command from the Oracle home of the primary OMS and pass the location where you want to configuration details can be exported as a file.

   $<OMS_HOME>/bin/emctl exportconfig oms -dir <absolute_path_to_directory>

5. Copy the exported configuration details file from the primary OMS host to the additional OMS host.

6. Copy the configuration details onto the additional OMS. To do so, run the following command from the Oracle home of the additional OMS:

   $<OMS_HOME>/bin/omsca recover -ms -backup_file <absolute_path_to_the_file_copied_in_step4> [-AS_HTTPS_PORT <port> -MSPORT <port> -MS_HTTPS_PORT <port> -EM_NODEMGR_PORT <port> -EM_UPLOAD_PORT <port> -EM_UPLOAD_HTTPS_PORT <port> -EM_CONSOLE_PORT <port> -EM_CONSOLE_HTTPS_PORT <port> -config_home <absolute_path_to_instance_dir> -EM_INSTANCE_HOST <second_oms_host_name>]

7. Configure the Management Agent on the additional OMS host by running the following command from the OMS home:

   $<AGENT_HOME>/sysman/install/agentDeploy.sh AGENT_BASE_DIR=<middleware_home>/agent OMS_HOST=<second_oms_host_name> EM_UPLOAD_PORT=<second_oms_port> AGENT_REGISTRATION_PASSWORD=<password> -configOnly

8. Deploy the required plug-ins on the Management Agent.

   For information about deploying plug-ins, refer to the section Deploying and Updating Plug-ins in the chapter Updating Cloud Control, in the Oracle Enterprise Manager Cloud Control Administrator's Guide.

9. Manually discover the Oracle WebLogic Server target.

   1. Ensure that both the primary and the additional OMSes are up and running.

   2. In the Cloud Control console, from the Targets menu, select Middleware.

   3. On the Middleware page, click EMGC_DOMAIN.

   4. On the EMGC_DOMAIN home page, from the Farm menu, select Refresh WebLogic Domain.

   5. On the Refresh WebLogic Domain page, click Continue.

      Enterprise Manager Cloud Control refreshes the WebLogic Domain and discovers the second managed server on the additional OMS host.

   For information about discovering the other targets, refer to the chapter Adding Targets in the Oracle Enterprise Manager Cloud Control Administrator's Guide.
