About the Oracle Inventory Directory and Installation
The directory that you designate as the Oracle Inventory directory (oraInventory) stores an inventory of all software installed on the system.
All Oracle software installation owners on a server are granted the OINSTALL privileges to read and write to this directory. If you have previous Oracle software installations on a server, then additional Oracle software installations detect this directory from the /var/opt/oracle/oraInst.loc
file, and continue to use that Oracle Inventory. Ensure that the group designated as the OINSTALL group is available as a primary group for all planned Oracle software installation owners.
-
In the path indicated in the ORACLE_BASE environment variable set for the installation owner user account
-
In an Optimal Flexible Architecture (OFA) path (u[01–99]
/app/
owner where owner is the name of the user account running the installation), and that user account has permissions to write to that path -
In the user home directory, in the path
/app/
owner, where owner is the name of the user account running the installation
For example:
If you are performing an Oracle Database installation, and you set ORACLE_BASE for user oracle
to the path /u01/app/oracle
before installation, and grant 755 permissions to oracle
for that path, then Oracle Universal Installer creates the Oracle Inventory directory one level above the ORACLE_BASE in the path ORACLE_BASE/../oraInventory
, so the Oracle Inventory path is /u01/app/oraInventory
. Oracle Universal Installer installs the software in the ORACLE_BASE path. If you are performing an Oracle Grid Infrastructure for a Cluster installation, then the Grid installation path is changed to root
ownership after installation, and the Grid home software location should be in a different path from the Grid user Oracle base.
/u01
, and grant oracle
755 permissions to write to that path, then the Oracle Inventory directory is created in the path /u01/app/oraInventory
, and Oracle Universal Installer creates the path /u01/app/oracle
, and configures the ORACLE_BASE environment variable for the Oracle user to that path. If you are performing an Oracle Database installation, then the Oracle home is installed under the Oracle base. However, if you are installing Oracle Grid Infrastructure for a cluster, then be aware that ownership of the path for the Grid home is changed to root
after installation and the Grid base and Grid home should be in different locations, such as /u01/app/21.0.0/grid
for the Grid home path, and /u01/app/grid
for the Grid base. For example:
/u01/app/oraInventory
, owned by grid:oinstall
/u01/app/oracle
, owned by oracle:oinstall
/u01/app/oracle/product/21.0.0/dbhome_1/
, owned by o
racle:oinistall
/u01/app/grid
, owned by grid:oinstall
/u01/app/21.0.0/grid
, owned by root
/app/
owner, where owner is the Oracle software installation owner. For example:/home/oracle/oraInventory
/home/oracle/app/oracle/product/21.0.0/dbhome_1
