Taking the Oracle Service Groups Offline

1. Log in as root user on one cluster system.
2. Take the Oracle database service groups in the VCS configuration offline. For example:
     # hagrp -offline oradb1_grp -sys galaxy
     # hagrp -offline oradb2_grp -sys galaxy
     # hagrp -offline oradb1_grp -sys nebula
     # hagrp -offline oradb2_grp -sys nebula

   These commands take the Oracle service groups, including all their configured resources, offline.

Using the uninstallDBAC Script

The uninstallDBAC script removes packages installed by installDBAC on all systems in the cluster. This script stops VCS and takes all service groups in the VCS configuration offline on each node.

1. As root user, change to the directory containing the uninstallDBAC program.
     # cd /opt/VRTSvcs/install
2. Start uninstallDBAC:
     # ./uninstallDBAC
3. The script begins by referring you to the appropriate chapters in this document and describing the packages it is to remove:
     Thank You for using the VERITAS Database Edition/Advanced
     Cluster. Please ensure that you have read the uninstallation
     chapter (to uninstall from the entire cluster) or the chapter 
     on removing DBE/AC cluster nodes (to uninstall from selected
     nodes) in the DBE/AC Installation and Configuration Guide.
     The following packages will be removed:
       VRTScavf    VRTSdbac    VRTSgab     VRTSglm     VRTSgms
       VRTSllt     VRTSodm     VRTSperl    VRTSvcs     VRTSvcsag
       VRTSvcsdc   VRTSvcsmg   VRTSvcsmn   VRTSvcsor
     The uninstallation procedure is interactive and requires
     responses to queries.
     Continue? [Y/N] :y

   ---

     Note    The following packages (and associated patches) used by DBE/AC are not removed by the uninstallDBAC script: VRTSvxvm, VRTSvmpro, VRTSfspro, VRTSob, VRTSobgui, and VRTSvxfs.

   ---

4. The script lists the systems in order from which it is to remove the packages, and creates files for the logging of the uninstallation activities:
     The packages will be removed on following nodes in the order
      given below:
                   galaxy
                   nebula
5. Note that the installation actions are recorded in a log:
     The output of the operations are temporarily being logged to
         /var/tmp/uninstallDBAC_062403_091711/logfile
6. The script verifies communications between the local system and the remote systems:
     Checking communication with nebula
     Pinging nebula
     Checking remsh connectivity............................... OK
     Communication check completed successfully
7. The script stops VCS and unconfigures DBE/AC drivers on each system:
     Stopping VCS on all systems..
     VCS successfully stoppped on system galaxy
     VCS successfully stoppped on system nebula
   
     Unconfiguring DBE/AC drivers on galaxy
       Unconfiguring CM driver ............................. Done

       Unconfiguring ODM  ...................................Done
       Closing CFS Port .................................... Done
       Closing QLOG Port ................................... Done
8. The script verifies whether the packages to be uninstalled are required or depended upon by other packages. It copies scripts and checks for packages on each node:
     Checking galaxy 
     Checking nebula 
9. The script removes VRTScavf, VRTSglm, VRTSgms, and VRTSodm packages:
   Removing VRTScavf VRTSglm VRTSgms VRTSodm from galaxy
     Removing VRTScavf ...................................... Done
     Removing VRTSglm ....................................... Done
     Removing VRTSgms ....................................... Done
     Removing VRTSodm ....................................... Done

     Removing VRTSglm ....................................... Done
     Removing VRTSgms ....................................... Done
     Removing VRTSodm ....................................... Done
10. The script displays the cluster information and prompts you to indicate that you want VCS packages uninstalled:
      VCS configuration files exist on this system with the following 
      information:
    
            Cluster Name: vcs_racluster
            Cluster ID Number: 7
            Systems: galaxy nebula
            Service Groups: cvm oradb1_grp oradb2_grp
      Do you want to uninstall VCS from all of the systems in this
      cluster? (Y) y
11. The script checks for the operating system level and for system-to-system communications:
      Checking OS version on galaxy ................... HP-UX B.11.11
      Verifying communication with nebula ........... ping successful
      Attempting remsh with nebula ................. remsh successful
