A
Directory Structure for Real Application Clusters Environments

Appendix A describes the directory structure for Real Application Clusters software environments. Specific topics covered in this appendix are:

• Understanding the Real Application Clusters Directory Structure

• UNIX Directory Structure for Real Application Clusters

• Windows NT and Windows 2000 Directory Structure for Real Application Clusters

Understanding the Real Application Clusters Directory Structure

When you install Oracle9i Enterprise Edition and Oracle9i Real Application Clusters, all subdirectories are under a top-level ORACLE_BASE. ORACLE_HOME and admin directories are also located under ORACLE_BASE.

UNIX Directory Structure for Real Application Clusters

The following is the hierarchical directory tree of a sample OFA-compliant database for Real Application Clusters on UNIX platforms:

$ORACLE_ BASE				/u01/app/oracle is the default ORACLE_BASE directory
	$ORACLE_HOME			/product/9.0.1 is the name of the Oracle home by default
		/bin		Subtree for Oracle binaries
		/network		Subtree for Oracle Net
		/srvm		Server Management message and TCL files
			/admin	clustdb.sql script and initialization parameter files for database creation
		/dbs		This is a legacy directory from previous releases. It contains links to initialization parameter files that point to the new location files, $ORACLE_BASE/admin/db_name/pfile.
		...
	/admin			Subtree for Real Application Clusters database administration files
		/db_name		Database administration files for this database identified by the database name
			/adhoc	Ad hoc SQL scripts
			/adump	Audit files
			/arch	Archived redo log files
			/bdump	Background process trace files
			/cdump	Core dump files
			/create	Programs used to create the database
			/exp	Database export files
			/pfile	Initialization parameter files
			/udump	User SQL trace files

Windows NT and Windows 2000 Directory Structure for Real Application Clusters

The following is the hierarchical directory tree of a sample OFA-compliant database for Real Application Clusters on Windows NT and Windows 2000:

x:\oracle_ base				c:\oracle is the default ORACLE_BASE directory.
	\%ORACLE_HOME%			\ora9.0.1 is the name of the Oracle home by default.
		\bin		Subtree for Oracle binaries.
		\network		Subtree for Oracle Net configuration files, including tnsnames.ora, listener.ora and sqlnet.ora.
		\srvm		\admin subdirectory.
			\admin	The Real Application Clusters script clustdb.sql and initialization parameter files for database creation
		\database		This is a legacy directory from previous releases. It contains initialization files that point to the new directory location for the initialization parameter files, ORACLE_BASE\admin\db_name\pfile.
		...
	\admin			Subtree for Real Application Clusters database administration files
		\db_name		db_name database administration files for the instance identified by sid.
			\adhoc	Ad hoc SQL scripts
			\adump	Audit files
			\arch	Archived redo log files
			\bdump	Background process trace files
			\cdump	Core dump files
			\create	Programs used to create the database
			\exp	Database export files
			\pfile	Initialization parameter files
			\udump	User SQL trace files
