Preparing to uninstall a single server on Linux

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.

About this task

Complete the following steps to prepare for uninstallation:

Procedure

  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 is 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
  2. Add passwords to the wkplc.properties, wkplc_dbdomain.properties, and wkplc_dbtype.properties files, located in the wp_profile_root/ConfigEngine/properties directory, or specify passwords on the command line.
  3. Decide whether to keep your database as is to preserve WebSphere Portal Express information or complete 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 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.sh WebSphere_Portal -username admin_userid -password admin_password from the wp_profile_root/bin directory.
    2. Run the ./stopServer.sh server1 -profileName cw_profile -username admin_userid -password admin_password from the AppServer_root/bin directory.
    3. Run the ./ConfigEngine.sh remove-schema -DWasPassword=password -Drelease.DbPassword=password -Dcustomization.DbPassword=password -Dcommunity.DbPassword=password -Djcr.DbPassword=password -Dfeedback.DbPassword=password -Dlikeminds.DbPassword=password task from the wp_profile_root/ConfigEngine directory to remove all database tables.
      Note: Some tables may remain in the IBM Java Content Repository database. Removing the database will remove these tables.
