This appendix describes the directory structures for Real Application Clusters (RAC) software environments. The topics in this appendix are:

Understanding the Real Application Clusters Directory Structure
UNIX Directory Structures for Real Application Clusters

Understanding the Real Application Clusters Directory Structure

When you install Oracle Database 10g with RAC, all subdirectories are under a top-level ORACLE_BASE. The ORACLE_HOME and admin directories are also located under ORACLE_BASE.

UNIX Directory Structures for Real Application Clusters

Table E-1 shows the hierarchical directory tree of a sample OFA-compliant database for RAC:

Table E-1 Directory Structure for A Sample OFA-Compliant Environment

Root	Second-Level	Third-Level	Fourth-Level	Fifth-Level
$ORACLE_BASE				`/u01/app/oracle` The default ORACLE_BASE directory.
	ORACLE_HOME			`/product/10.1` The default name of the Oracle home.
	`/admin`			Administrative directory.
		`/db_unique_name`		Database unique name, the same as `dbname` when database name is eight or fewer characters in length.
			`/bdump` `/cdump` `/hdump` `/pfile` `/udump`	Dump destinations for database server.
	`CRS Home`			`/crs/10.1` The default name of the CRS home.
		`/bin`		Subtree for Oracle binaries.
		`/network`		Subtree for Oracle Net.
