Support for Oracle RAC is supported on two types of cluster file systems:
Cluster file systems that use the Oracle Solaris Cluster Proxy File System (PxFS)
For general information about how to create and mount PxFS-based cluster file systems, see the following documentation:
Oracle Automatic Storage Management Cluster File System (Oracle ACFS)
For general information about how to create and mount an Oracle ACFS file system, see Creating Oracle ACFS File Systems in Oracle Solaris Cluster 4.3 Software Installation Guide .
For information that is specific to the use of cluster file systems with Support for Oracle RAC, see the subsections that follow.
Types of Oracle Database Files That You Can Store on a PxFS-Based Cluster File System
Types of Oracle Database Files That You Can Store on an Oracle ACFS File System
Optimizing Performance and Availability When Using a PxFS-Based Cluster File System
You can store only these files that are associated with Support for Oracle RAC on a PxFS-based cluster file system:
Oracle Database RDBMS binary files
Oracle Database configuration files (for example, init.ora, tnsnames.ora, listener.ora, and sqlnet.ora)
System parameter file (SPFILE)
Alert files (for example, alert_sid.log)
Trace files (*.trc)
Archived redo log files
Flashback log files
Oracle Grid Infrastructure cluster registry (OCR) files
Oracle Grid Infrastructure voting disk
You can store only these files that are associated with Support for Oracle RAC on the Oracle ACFS file system:
Oracle Database RDBMS binary files
Oracle Database configuration files (for example, init.ora, tnsnames.ora, listener.ora, and sqlnet.ora)
Alert files (for example, alert_sid.log)
Trace files (*.trc)
(Starting with Oracle Database 12c) Data files
(Starting with Oracle Database 12c) Control files
(Starting with Oracle Database 12c) Online redo log files
(Starting with Oracle Database 12c) Archived redo log files
(Starting with Oracle Database 12c) Flashback log files
(Starting with Oracle Database 12c) Recovery files
The 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 RAC database instance. This device group contains the file system that holds archived redo log files of the database instance.
To improve the availability of your cluster, consider increasing the desired number of secondary nodes for device groups. However, increasing the desired number of secondary nodes for device groups might also impair performance. To increase the desired number of secondary nodes for device groups, change the numsecondaries property. For more information, see Device Group Ownership in Oracle Solaris Cluster 4.3 Concepts Guide .
See Creating Cluster File Systems in Oracle Solaris Cluster 4.3 Software Installation Guide for information about how to create and mount the cluster file system.
For the correct options, see the table that follows. You set these options when you add an entry to the /etc/vfstab file for the mount point.

Next Steps
Ensure that all other storage management schemes that you are using for Oracle Database files are installed. After all storage management schemes that you are using for Oracle Database files are installed, go to Chapter 3, Registering and Configuring the Resource Groups.
See Creating Oracle ACFS File Systems in Oracle Solaris Cluster 4.3 Software Installation Guide for information about how to create and mount the Oracle ACFS file system.
