Requirements for Using the Cluster File System

You can store only these files that are associated with Oracle Real Application Clusters on the cluster file system:

• Oracle binary files

• Oracle configuration files (for example, init.ora, tnsnames.ora, listener.ora, and sqlnet.ora)

• Archived redo log files

• Alert files (for example, alert_sid.log)

• Trace files (*.trc)

You must not store data files, control files, or online redo log files on the cluster file system.

The input/output (I/O) performance during the writing of archived redo log files is affected by the location of the device group for archived redo log files. For optimum performance, ensure that the primary of the device group for archived redo log files is located on the same node as the Oracle Real Application Clusters database instance. This device group contains the file system that holds archived redo log files of the database instance.
