Configuration of Sun StorEdge QFS Resource Groups With Oracle 10g R1

If you are using Oracle 10g, Oracle CRS manage RAC database instances. These database instances must be started only after all shared file systems are mounted.

You might use multiple file systems for database files and related files. For more information, see Sun StorEdge QFS File Systems for Database Files and Related Files. In this situation, ensure that the file system that contains the Oracle CRS voting disk is mounted only after the file systems for other database files have been mounted. This behavior ensures that, when a node is booted, Oracle CRS are started only after all Sun StorEdge QFS file systems are mounted.

If you are using Oracle 10g R1, the configuration of resource groups must ensure that Sun Cluster mounts the file systems in the required order. To meet this requirement, configure resource groups for the metadata servers of the file systems as follows:

• Create the resources for the metadata servers in separate resource groups.

• Set the resource group for the file system that contains the Oracle CRS voting disk to depend on the other resource groups.
