Preparing to uninstalling on i5/OS

Before uninstalling IBM^® WebSphere^® Portal Express, you must prepare your system; for example, adding passwords to the properties files and keeping or discarding database information.

1. Optional: Make a backup of the WebSphere Portal Express configuration using the XML Configuration Interface.
   Important: The following information is not backed up and will be deleted if you delete the database:

   • User attributes that are stored in the database and not in the user registry
   • Credential data that is stored in the default vault implementation
   • Data used be Document Manager
2. Decide whether to keep your database as is to preserve WebSphere Portal Express information or perform the following steps to remove the information from the database:
   Note: If you choose to keep the database information, you cannot use it with subsequent WebSphere Portal Express installations although you can still access the information through your database software. Also, if you keep the information, you can always delete the WebSphere Portal Express databases and database tables later using your database software.
   1. Run the stopServer WebSphere_Portal -profileName profile_root -user admin_userid -password admin_password from the wp_profile_root\bin directory.
   2. Choose one of the following options to delete the database information:

      If your database is a...	Then perform the following steps:
      Local DB2 for i5/OS	Run the ConfigEngine.sh -profileName profile_root remove-schema -Drelease.DbPassword=password -Dcustomization.DbPassword=password -Dcommunity.DbPassword=password -Djcr.DbPassword=password -Dwmm.DbPassword=password -Dfeedback.DbPassword=password -Dlikeminds.DbPassword=password task from the wp_profile\ConfigEngine directory to remove all database tables.
      Remote DB2 for i5/OS	Use a 5250 PC session to log on to the system where the remote database exists. Type wrklib prefix* on the command line to display a list of all libraries created for the remote database, where prefix is the prefix for your database name. Type 4 in the Opt field beside each library name that you want to delete and then press Enter.

3. Perform the following steps to remove references to IBM Workplace™ Collaboration Services shared library:
   1. Run the serverStatus.sh server1 -user username -password password task from the wp_profile_root/bin directory to verify that server1 is active.
   2. Run the ConfigEngine.sh -profileName profile_root remove-lwp-shared-library -DPortalAdminPwd=password task from the profiles/wp_profile/ConfigEngine directory.
4. Run the following tasks to stop the server1 and WebSphere_Portal servers:
   1. stopServer server1 -profileName profile_root -user admin_userid -password admin_password
   2. stopServer WebSphere_Portal -profileName profile_root -user admin_userid -password admin_password
5. Verify that there are no other installations or uninstallations running.
