Note:
■ Ensure that the home directory does not reside in the root or var
file system.
■ The USER-NUMBER must be unique and greater than 100.
■ The GROUP-NUMBER must be the number of the Oracle installation
group.
3.3.5 Identify Required Directories in POSIX
You must identify or create the following directories in the POSIX file system for the
Oracle software:
■ Oracle Base Directory
■ Oracle Inventory Directory
■ Oracle Home Directory
3.3.5.1 Oracle Base Directory
Oracle base directory is a top-level directory for Oracle software installations. Oracle
recommends using a path similar to the following for the Oracle base directory:
/mount_point/app/software_owner
In this example:
■ mount_point is the mount point directory for the file system that contains the
Oracle software. The examples in this guide use
/u01 for the mount point
directory.
■ software_owner is the operating system user name of the software owner
installing the Oracle software.
The components
/mount_point/app represent the operating system part of the path.
Before you start the installation of Oracle Database 11g Release 2, you must create the
operating system part of the path.
