As part of the patch installation process, Operations Center automatically backs up all files that are overwritten and places them in a file called patch_filename-rollback.jar, such as 500-201080723-NOC-rollback.jar.
If you decide to remove the changes made by the patch to Operations Center, run this rollback JAR file from the Operations Center root installation directory. The command for running the rollback file is the same as when the patch is installed. For example:
C:/OperationsCenter_install_path>java -jar 500-20100723-NOC-rollback.jar
When multiple rollback patches are applied using the same command, they are applied in the reverse order.
