About VCS service group for Oracle 10g dependencies

Review the information on how to set up VCS to automate the Oracle 10g RAC environment and how VCS manages resources within a cluster.

VCS service group dependencies are based on whether you use the VCS Oracle agent or not. Configuration without the Oracle agent and Configuration with the Oracle agent illustrate the dependencies.

• In a configuration without the VCS Oracle agent, CRS controls the database.

  See Configuration without the Oracle agent.

• In a configuration with the VCS Oracle agent, VCS controls the Oracle database. An online local firm dependency exists between the Oracle group and the CVM group. For more details on service group dependencies, refer to the Veritas Cluster Server User's Guide.

  See Configuration with the Oracle agent.

CRS and Oracle agent might attempt to start the instance at the same time if the database mount is available. To prevent automatic database starting, you must change the Management policy for the database (automatic, manual) to MANUAL using SRVCTL command. The command will change AUTO_START attribute of CRS database and instance resources.

 To prevent automatic database starting

• Depending on the status of the database:
  • If the database is already registered and running:

    To change it to manual execute the following commands as Oracle user:

    $ srvctl stop database -d db-name

    $ srvctl modify database -d db-name -y manual

  • If the database is not registered, use the following command to register database:

    $ srvctl add database -d db-name -p \

    location-of-parameter-file -y manual
