Configuring CVM and Oracle service groups manually

CVM and Oracle groups can be configured manually or by using the VCS Oracle RAC Configuration Wizard. This section describes how to manually edit the main.cf file to configure the CVM and Oracle service groups.

 To configure CVM and Oracle service groups manually

1. Log in to one system as root.
2. Save your existing configuration to prevent any changes while you modify main.cf:

   # haconf -dump -makero

3. Ensure VCS is not running while you edit main.cf by using the hastop command to stop the VCS engine on all systems and leave the resources available:

   # hastop -all -force

4. Make a backup copy of the main.cf file:

   # cd /etc/VRTSvcs/conf/config

   # cp main.cf main.orig

5. Using vi or another text editor, edit the main.cf file, modifying the cvm service group and creating Oracle service groups using the guidelines in the following sections.
