10 Deinstall the Oracle Database and EMCC

If you only want to remove the JD Edwards EnterpriseOne Domain, refer to the chapter of this guide entitled: Section 8.17, "Removing the JD Edwards EnterpriseOne Domain".

To undeploy the JD Edwards EnterpriseOne Application Pack components, refer to the chapter of this guide enitlted: Chapter 9, "Undeploy JDE AppPack Components".

This chapter discusses these topics:

10.1 Stop the Agent, OMS, and Database Using Line Commands

You should these commands, in this sequence, to stop the Enterprise Manager Agent, the OMS, and the Oracle database using by Enterprise Manager prior to deinstalling any product.

  1. On the machine where the database that is being used by Enterprise Manager is running, stop the database using these commands:

    sqlplus '/as sysdba'

    shutdown immediate

  2. On the machine where the database that is being used by Enterprise Manager is installed, stop the database listener using the lsnrctl stop command. This command is run from the /oracle/home/bin directory. For example, your /oracle/home/bin directory and command line might be:

    /u01/app/oracle/home/bin/lsnrctl stop

  3. Stop OMS using the stop oms command, which stops both the Admin Server and the OMS Server. This command is run from the oms/bin directory. For example, your oms/bin directory and command line might be:

    /u01/app/emgc12/oms/bin/emctl stop oms

  4. Stop the EMCC agent using the stop Agent command. This command is run from the bin directory of the agent installation directory. For example, your /bin directory and command line might be:

    /u01/app/emgc12/agent/agent_inst/bin/emctl stop agent

  5. Verify there no additional Oracle processes are running using this command:

    ps –r | grep oracle

    Note:

    A likely example of an Oracle process that might be running is for the WebLogic Server Node Manager.

  6. Kill any Oracle-based java process which are listed as results from the above command.

10.2 Deinstall the Oracle Database and EMCC Using OUI

You use the Oracle Universal Installer (OUI) to deinstall the Oracle EMCC. This section provides an example deinstall based on the install examples described in the chapters of this guide entitled:

To deinstall the Oracle database and EMCC using OUI:

  1. Change to the oui/bin directory and run the OUI runInstaller.sh script. For example, your oui/bin and command line might be:

    /u01/app/oracle/home/oui/bin/runInstaller.sh

    This image is described in surrounding text.

  2. On Oracle Universal Installer: Welcome, click the Deinstall Products ... button.

    This image is described in surrounding text.

  3. On Inventory, check every checkbox except the checkbox for the Oracle Database Home. For example, do not select this checkbox:

    OraDB11g_home1

  4. Click the Remove button.

    This image is described in surrounding text.

  5. On Confirmation, click the Yes button to deinstall all Oracle components except the database home, which cannot be deinstalled until all other components are first deinstalled.

    This image is described in surrounding text.

    The Remove dialog shows the progress of the deinstallation actions.

    This image is described in surrounding text.

  6. On Inventory, verify the only remaining Oracle products is the Oracle database home. For example:

    OraDB11g_home1

  7. On Inventory, select the checkbox for the Oracle database home and click the Remove button.

    This image is described in surrounding text.

  8. A Warning displays this text:

    Please run the command '/u01/app/oracle/home/deinstall/deinstall' to deinstall this Oracle home.

  9. As instructed in the Warning, open a UNIX console window and issue these commands to change to the /oracle/home/deinstall directory and run the deinstall.sh script:

    This image is described in surrounding text.

  10. The deinstall.sh script launches the Oracle Deinstall and Deconfiguration Tool and displays the following console, where the bolded sections are user prompts. This console listing shows users responses that are applicable for this example. If no reponse is shown in the console session, then the default action is assumed as triggered by the user input pressing of the Enter key. You should refer to the Oracle OEM documentation and provide user responsibles applicable to your installation.
