Sun StorEdge QFS File Systems for Database Files and Related Files

For database files and related files, determine whether you require one file system for each database or multiple file systems for each database.

• For simplicity of configuration and maintenance, create one file system to store these files for all Oracle Real Application Clusters instances of the database.

• To facilitate future expansion, create multiple file systems to store these files for all Oracle Real Application Clusters instances of the database.

If you are adding storage for an existing database, you must create additional file systems for the storage that you are adding. In this situation, distribute the database files and related files among the file systems that you will use for the database.

Each file system that you create for database files and related files must have its own metadata server. For information about the resources that are required for the metadata servers, see SPARC: Resources for the Sun StorEdge QFS Shared File System.

The database files and related files are as follows:

• Data files

• Control files

• Online redo log files

• Archived redo log files

• Flashback log files

• Recovery files

• Oracle cluster registry (OCR) files

• Oracle CRS voting disk
