Prepare to uninstall on Solaris

Before uninstalling the cluster, prepare your system; for example, adding passwords to the properties files and keeping or discarding database information.

To prepare for uninstallation:

You must issue the removeNode command to unfederate a node prior to uninstalling because WebSphere Portal cannot uninstall a federated node.

  1. Optional: Make a backup of the WebSphere Portal configuration using xmlaccess.

    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

  2. In a federated node, run the ./ -force -user user_name -password password task



    , to remove the node from the Deployment Manager cell and return it to a stand-alone appserver.

  3. Add passwords to the,, and files, located in...


    or specify passwords on the command line.

  4. Decide whether to keep your database as is to preserve WebSphere Portal information or perform the following steps to remove the information from the database:

    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 databases and database tables later using your database software.

    1. Run the ./ WebSphere_Portal -username admin_userid -password admin_password from the profile_root/bin directory.

    2. Run...

        ./ remove-schema -DWasPassword=password -Drelease.DbPassword=password -Dcustomization.DbPassword=password -Dcommunity.DbPassword=password -Djcr.DbPassword=password -Dfeedback.DbPassword=password -Dlikeminds.DbPassword=password


        profile_root/ConfigEngine remove all database tables.

      Some tables may remain in the IBM Java Content Repository database. Removing the database will remove these tables.

  5. Optional: To remove a node from the cell:

    Removing a WebSphere Portal node from the cell does not affect the cluster definition you originally created for the cluster. The cluster definition remains intact even after removing all WebSphere Portal nodes from the cell.

    In addition, removing a WebSphere Portal 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.

    1. Click Servers > Clusters > cluster_name > Cluster members, where cluster_name is the name of the cluster, click the server you want to stop, and then click Stop.

    2. Click System Administration > Nodes, select the node containing the server you want to remove from the cell, and then click Remove Node to remove the node from the cell.

      Make sure that you choose the Remove Node option to remove the node from cell and not the Delete option on the Cluster members view. Using the Delete option completely deletes the node, which removes the existence of the server from the deployment manager and does not leave a means for restoring the WebSphere Portal node to a stand-alone system. Using the Delete option can prevent the WebSphere Portal server from working after it is deleted from the cluster. If Remove Node does not successfully remove the node, click Force Delete to remove the node.

    3. Click Save to save the changes made to the cell's configuration.

    4. Repeat the above steps for each node in the cluster and cell that needs to be uninstalled.

    5. Optional: Perform the following steps if you plan to convert the stand-alone server to a working portal:

      1. Edit

      2. Change the value of the CellName property so that it matches the cell name of the node itself.

        • When you remove the node from the cell, the cell name for the node reverts to the cell name that was used before you federated the node.

        • The cell name can be identified by the AppServer_root/cells/cell_name directory on the node, where cell_name indicates the cell to which the node belongs.

      3. Change the value of the ServerName property to the original WebSphere Portal server name.

      4. Ensure that the value of the PrimaryNode property is set to true.

      5. Save changes.
