7.3.4 Check for Previous Oracle Installations on All Nodes
Check that all the nodes where you want to install in a high availability configuration
do not have existing
oraInventory
directories.
Details of all Oracle software installations are recorded in the Oracle Installer
Inventory directory. Typically, this directory is unique to a node and named
oraInventory
. The directory path of the Oracle Installer Inventory directory is
stored in the
oraInst.loc
file.
The existence of this file on a node confirms that the node contains some Oracle
software installation. Since the high availability configurations require installations on
multiple nodes with Oracle Installer Inventory directories on a file system that may
not be accessible on other nodes, the installation instructions in this chapter and
subsequent chapters for high availability configurations assume that there have not
been any previous installations of any Oracle software on any of the nodes that are
used for this high availability configuration. The
oraInst.loc
file and the Oracle
Installer Inventory directory should not exist on any of these nodes prior to these high
availability installations.
To check if a node contains an
oraInventory
directory that could be detected by the
installer:
1.
On each node, check for the existence of the
oraInst.loc
file. This file is stored
in the
/var/opt/oracle
directory.
If a node does not contain this file, then it does not have an
oraInventory
directory that will be used by the installer. You can check the next node.
2.
For nodes that contain the
oraInst.loc
file, rename the file and the
oraInventory
directory. The installer then prompts you to enter a location for a
new
oraInventory
directory.
For example enter the following commands as
root
:
#
cat /var/opt/oracle/oraInst.loc
inventory_loc=/localfs/app/oracle/oraInventory
inst_group=dba
# mv
/var/opt/oracle/oraInst.loc /var/opt/oracle/oraInst.loc.orig
# mv
/localfs/app/oracle/oraInventory /localfs/app/oracle/oraInventory.orig
Because the
oraInst.loc
file and the Oracle Installer Inventory directory are
required only during the installation of Oracle software, and not at runtime, renaming
them and restoring them later does not affect the behavior of any installed Oracle
software on any node. Make sure that the appropriate
oraInst.loc
file and Oracle
Installer Inventory directory are in place before starting the Oracle Universal Installer.
Note:
For an OracleAS Disaster Recovery configuration, the correct
oraInst.loc
file and associated
oraInventory
directory are
required during normal operation, not just during installation.
