IBM i: Preparing to uninstall
You must prepare your system before you uninstall your HCL Digital Experience environment. For example, add passwords to the properties files. You must also decide to keep or discard the database information.
About this task
Important cluster note: You must issue the removeNode command to unfederate a node before uninstalling because HCL cannot uninstall a federated node.
Procedure
- Optional: Make a backup of the HCL configuration. Use
the XML Configuration Interface.Important: If you delete the database, the following information is not backed up and is deleted:
- User attributes that are stored in the database and not in the user registry
- Credential data that is stored in the default vault implementation
- Complete the following steps to remove a node from the
cell in a clustered environment:Note: Removing a HCL node from the cell does not affect the cluster definition that you originally created for your cluster. The cluster definition remains intact even after you remove all HCL nodes from the cell. In addition, removing a HCL node from the cell does not remove the product's enterprise applications from the deployment manager. The enterprise applications remain and continue to be associated with the cluster definition.
- Add passwords to the wkplc.properties, wkplc_dbdomain.properties, and wkplc_dbtype.properties files in the wp_profile_root/ConfigEngine/properties directory. You can also specify passwords on the command line.
- Decide whether to keep your database to preserve HCL information.
- If you keep the database, no further steps are required.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 HCL databases and database tables later with the database software.
- Complete the following steps to remove the information from
the database:
- Stop all the servers. For specific instructions, go to Starting and stopping servers, deployment managers, and node agents.
- Open a command prompt and change to the wp_profile_root/ConfigEngine directory.
- 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.
Note: Some tables remain in the IBM® Java™ Content Repository database. Removing the database removes these tables.
- If you keep the database, no further steps are required.
