Uninstalling Rule Execution Server from a cluster

You can uninstall Rule Execution Server from an existing cluster.

1. Navigate to the profiles/<profile_name>/bin directory.
2. Start the configureDSCluster[.sh|.bat] script with the -uninstall argument.

   The command line is:

   configureDSCluster[.sh|.bat] -dmgrAdminUsername username 
    -dmgrAdminPassword password  -clusterPropertiesFile filePath -uninstall

   • On Windows:

     <WAS_InstallDir>\profiles\Dmgr01\bin\configureDSCluster.bat 
      -dmgrAdminUsername websphere -dmgrAdminPassword websphere -clusterPropertiesFile
      <WAS_InstallDir>\profiles\Dmgr01\bin\rules\configureDSCluster.properties
      -targetNodeName DecisionServerNode01 -dmgrHostName localhost -dmgrPort 8879 -uninstall 

   • On UNIX:
