Understanding the Oracle Parallel Server Directory Structure

When you install Oracle8i Enterprise Edition and the Oracle Parallel Server Option, all subdirectories are under a top-level ORACLE_BASE. ORACLE_HOME and admin directories are also located under ORACLE_BASE.

UNIX

The following is the hierarchical directory tree of a sample OFA-compliant database for Oracle Parallel Server on UNIX platforms:

$ORACLE_ BASE				`/u01/app/oracle` is the default ORACLE_BASE directory
	$ORACLE_HOME			`/product/8.1.5` is the name of the Oracle home by default
		/bin		Subtree for Oracle binaries
		/network		Subtree for Net8
		/ops		Files necessary for Oracle Database Configuration Assistant
		/opsm		Oracle Parallel Server Management message and TCL files
		/dbs		This is a legacy directory from previous releases. It contains links to initialization files that point to the new location of the initialization parameter files, `$ORACLE_BASE/admin/``db_name``/pfile`.
		...
	/admin			Subtree for Oracle Parallel Server 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

For more information about the contents of the $ORACLE_HOME and /admin directories, see Oracle8i Administrator's Reference for Sun Solaris, HP 9000 or AIX-based systems.

Windows NT

The following is the hierarchical directory tree of a sample OFA-compliant database for Oracle Parallel Server on Windows NT:

x:\oracle_ base				`c:\oracle` is the default ORACLE_BASE directory
	\oracle_home			`\ora81` is the name of the Oracle home by default
		\bin		Subtree for Oracle binaries
		\network		Subtree for Net8 configuration files, including TNSNAMES.ORA, LISTENER.ORA and SQLNET.ORA
		\ops		*.TBL sample files to create raw partitions for the Oracle Database Configuration Assistant
		\database		This is a legacy directory from previous releases. It contains initialization files that points to the new directory location for the initialization parameter files, `oracle_base``\``db_name``\pfile`.
		...
	\admin			Subtree for Oracle Parallel Server 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

For more information about the contents of the ORACLE_HOME and \admin directories, see Oracle Parallel Server Getting Started for Windows NT.
