Preparing to uninstall WebSphere Portal Express

Before uninstalling WebSphere Portal Express, you will need to prepare your system; for example, add your passwords back to the properties files, disable security, and keep or discard database information.

Use the following steps to prepare for the uninstallation:

1. You can make a backup of WebSphere Portal Express configuration using the XML configuration interface (xmlaccess). In addition, you have the option to delete or keep the WebSphere Portal Express database. The following data is not saved by an XML configuration export and will be deleted if you remove the database:

   • User attributes that are stored in the database and not in LDAP

   • Credential data that is stored in the default vault implementation

   • Data that is used by the Document Manager

2. Password considerations: For security reasons, you should not store passwords in the wpconfig.properties, wpconfig_dbdomain.properties, or wpconfig_dbtype.properties file. IBM recommends that you edit each file prior to running a configuration task, inserting the passwords needed for that task. Then, after the task has run, you should delete all passwords from each file. For more information, see Deleting passwords from configuration scripts. Alternatively, you can specify the password on the command line using the following syntax:

   • Linux:

     WPSconfig.sh task_name -Dpassword_property_key=password_value

   • Windows:

     WPSconfig.bat task_name -Dpassword_property_key=password_value

   As with other properties, each password property must have the -D prefix and be set equal to (=) a value. If you have multiple properties in a single command, use a space character between each -Dproperty=value setting.

3. Stop servers if you are running with security enabled. Refer to the specific instructions here for stopping the WebSphere Application Server administrative server, and to these specific instructions for stopping the WebSphere Portal Express application server.

4. Ensure that no other installation or uninstallation is running. Locate and delete the portalinstall.lockfile:

   • Linux:

     /tmp/portalinstall.lockfile

   • Windows:

     C:\Documents and Settings\Administrator\Local Settings\Temp\portalinstall.lockfile
