Deinstalling OracleAS Cold Failover Cluster Installations
D-4 Oracle Application Server Installation Guide
The installer does not permit custom deinstallation of individual components.
D.3 Deinstalling OracleAS Cold Failover Cluster Installations
If you are deinstalling an OracleAS Cold Failover Cluster installation:
1. Stop the clusterware agents or packages that monitor and fail over the
environment. See your clusterware documentation for details.
2. Then perform the steps described in this appendix.
If you do not take the resources offline, the installer will hang during the deinstallation
because the clusterware agents are trying to fail over the resources.
D.4 Deinstalling OracleAS Single Sign-On Instances in OracleAS Cluster
(Identity Management)
If you have multiple OracleAS Single Sign-On instances installed in a cluster against
the same Oracle Internet Directory and you would like to deinstall some of the
instances but keep others running, perform the following steps before running the
Deconfig tool.
Note that if the OracleAS Single Sign-On instance that you wish to deinstall was the
last instance to be installed against the Oracle Internet Directory, you should not
perform this step. Instead, perform the steps in
Section D.6, "Deinstalling OracleAS
Infrastructure" .
1. Open the file located at ORACLE_
HOME/deconfig/DeconfigWrapper.properties
for editing.
2. Search for the line that begins with "SSO=". For example, the line might look like
the following:
SSO=/OraHome_1/jdk/bin/java -jar /OraHome_1/sso/lib/ossoca.jar deinstall
/OraHome_1 "%OID_USER%" %OID_PASSWORD%
3. Comment out the line by adding a pound (#) character at the beginning of the line.
In the example above, the line would be changed to look like the following:
# SSO=/OraHome_1/jdk/bin/java -jar /OraHome_1/sso/lib/ossoca.jar deinstall
/OraHome_1 "%OID_USER%" %OID_PASSWORD%
After modifying the file, perform the steps in Section D.6, "Deinstalling OracleAS
Infrastructure" to complete the deinstallation.
