Manually removing InfoSphere Information Server from the repository 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 repository 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. If you installed IBM®Db2® database system as part of the InfoSphere® Information Server installation, remove the Db2 database system from the computer on which you installed the repository tier. Removing the Db2 database system automatically removes the metadata repository database and the analysis database.
    1. Log in as the Db2 instance owner. This account is db2inst1 by default.
    2. Drop the databases by running the following commands:
      db2 drop database xmeta
      db2 drop database iadb
      This example uses the default database names: xmeta and iadb. If you used different names, use your database names instead.
    3. If you installed the Db2 database system as part of the installation of InfoSphere Information Server and it is the only Db2 installation, remove the Db2 database system. See the Db2 Information Center for more information on removing the Db2 database system.
    4. Use the following commands to remove any remaining files:
      rm -rf /tmp/db2*
      rm -rf /var/db2
      rm -rf /var/opt/db2
      rm -rf ~db2inst1/db2inst1
      rm -rf ~db2inst1/sqllib
      rm -rf /opt/IBM/db2
      This example uses the default paths and user accounts. If you used different paths and user accounts, use your paths and user accounts instead.
    5. Remove any entries in the /etc/services file that start with DB2_db2inst1 or db2c_db2inst1 where db2inst1 is the name of the instance owner that you used during the suite installation.
    6. If the /etc/inittab file exists and this is the only Db2 database system installation, open the file and search for and remove the fmc entry. The following example shows what this entry might look like:
      #DB2 Fault Monitor Coordinator
      fmc:number:respawn:/opt/IBM/db2/V10.5/bin/db2fmcd
  3. If you used an existing installation of Db2 database system, use the Db2 command prompt to drop the metadata repository database and the analysis database. The default database names are xmeta and iadb.
  4. If you used Oracle database system or Microsoft SQL Server database system to create the metadata repository database and the analysis database, manually drop the databases. The default database names are xmeta and iadb.
  5. Delete the InfoSphere Information Server installation directory.
    The default directory is /opt/IBM/InformationServer.
  6. 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.
  7. 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
  8. Remove any InfoSphere Information Server users and groups if you are not using them for other purposes.
  9. Restart the computer to ensure that all processes have been terminated.
