Manually removing InfoSphere Information Server from the engine tier (AIX Linux)

If you cannot remove suite software by using the software removal program, then you must manually remove files and directories from the engine tier computer to ensure that the product is completely removed. Completely removing this files and directories is important if you plan to reinstall the suite.

Procedure

  1. Back up the computer.
  2. Log in as the root user and complete the following steps to stop and remove services:
    1. Change directories to the installation directory for the InfoSphere® Information Server engine. The default location is /opt/IBM/InformationServer/Server/DSEngine.
    2. Run the following command to source the dsenv file to configure the required environment variables:
      . ./dsenv
    3. Run the following command to stop the engine services:
      ./bin/uv -admin -stop
    4. Change to the InfoSphere Information Server installation directory. The default directory is /opt/IBM/InformationServer.
    5. Run the following command to stop the agents:
      ./ASBNode/bin/NodeAgents.sh stop
    6. Run the following command to determine which startup entries to remove.
      The NodeAgents.sh file is started automatically by symbolic links in the rc directory. AIX® Linux®: The directory is /etc/rc.d.
      find /etc -name "*" -print | xargs grep -i installation_dir
      installation_dir is the directory where you installed InfoSphere Information Server. The default directory is /opt/IBM/InformationServer.
    7. Remove all entries that contain DFDServer, DSEngine, ODFEngine, and ISFAgent.
      Note: To remove DFD from engine tier, the DFD server must be stopped before stopping the node agent.
      Use the following command to stop the DFD server:
      /opt/IBM/InformationServer/ASBNode/CognitiveDesignerEngine/stopCognitiveDesignerServer.sh
      The command must be executed on the engine-tier-system.
    8. Open the /etc/services file, and search for and remove the entry that starts with dsrpc entry. The following example shows what this entry might look like:
      dsrpc 31538/tcp # RPCdaemon DSEngine@/opt/IBM/InformationServer/Server/
         DSEngine
  3. Delete the InfoSphere Information Server installation directory.
    The default directory is /opt/IBM/InformationServer.
  4. Delete the temporary log files for the installation program by running the following command:
    rm -rf /tmp/ibm_is_logs
    Note: If you chose a different directory for the temporary files, delete that directory instead of the default directories.
  5. Delete the InfoSphere DataStage® installation location file by running the following command:
    rm -rf /.dshome
  6. Delete the InfoSphere DataStage log files by running the following command:
    Operating system Command
    AIX
    rm -rf /ds_logs
    Linux
    rm -rf /root/ds_logs
  7. Remove any InfoSphere Information Server users and groups if you are not using them for other purposes.
  8. Restart the computer to ensure that all processes have been terminated.
