This section provides a high-level overview of the contents of the VCS configuration file after the SF Oracle RAC installation. Review the configuration file after the SF Oracle RAC installation and before the Oracle installation.
The configuration file includes the following information:
The "include" statements list the various VCS types files (.cf) for SF Oracle RAC.
The files are located in the /etc/VRTSvcs/conf/config directory. These files define the agents that control the resources in the cluster.
The cluster definition, with the cluster name provided during installation (for example, rac_cluster101), includes the names of users and administrators of the cluster. The UseFence = SCSI3 attribute is not automatically present; you must manually add it after the installation.
The main.cf includes the cvm service group. The service group includes definitions for monitoring the CFS and the CVM resources. The CVMCluster agent resource definition indicates that the nodes use GAB for messaging operations.
The cvm group has the Parallel attribute set to 1. This value enables the resources to run in parallel on each node in the system list.
