Deinstalling OracleAS Cold Failover Cluster Installations

Oracle Application Server Installation Guide

The installer does not permit custom deinstallation of individual components.

If you are deinstalling an OracleAS Cold Failover Cluster installation:

Stop the clusterware agents or packages that monitor and fail over the 
environment. See your clusterware documentation for details.

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.

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 

Open the file located at ORACLE_
HOME/deconfig/DeconfigWrapper.properties

 for editing.

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%

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 

 to complete the deinstallation.
