Upgrading JRockit Version For WebLogic Server Instances

Description: This post will show you the necessary steps to replace an old version of JRockit with a newer one.

1. Download the latest JRockit version from Oracle and install it.

2. Shutdown all the WebLogic server instances (E.g. OIM, SOA, AdminServer) and Node Manager processes.

3. Update JAVA_HOME variable in the following files:

• User Bash Profile (E.g. "~/.bash_profile")
• $MW_HOME/wlserver_10.3/common/bin/commEnv.sh
• $MW_HOME/user_projects/domains/<domainName>/bin/setDomainEnv.sh
  (Also modify BEA_JAVA_HOME variable)
• $MW_HOME/utils/bsu/bsu.sh
• $MW_HOME/utils/quickstart/quickstart.sh
• $MW_HOME/utils/uninstall/uninstall.sh

4. Update "javaHome" and "JavaHome" parameters in the node manager properties file.

• $MW_HOME/wlserver_10.3/common/nodemanager/nodemanager.properties

5. Edit OIM design console script to use the new JRockit path.

• $MW_HOME/Oracle_IDM1/designconsole/xlclient.sh

6. Restart the operating system.

7. Validate the new java version is running.

• java -version
• which java
• Check server instances and nodemanager logs to see if correct JRockit version is running

Side Note:
In Unix, you can execute the following command to see if any shell scripts files still reference the old java home path:

# Replace JAVA_HOME with absolute path to java home directory
find . -type f -name "*.sh" -exec grep -il JAVA_HOME {} \;
