Updating the JDK after installation

If the Sterling™ Call Center installation directory contains a JDK, you can use the updateJDK tool to update the JDK in the Sterling Call Center run time.

About this task

For example, if you upgrade the JDK to a new version, you must replace the JDK in the Sterling Call Center run time with the new version JDK.

Note:

If your Sterling Call Center installation directory does not contain a JDK, you cannot use the updateJDK tool to update your JDK for Sterling Call Center. Instead, copy the following jar files, which are included in the IBM Sterling Call Center software installer image, to the <JAVA_HOME>/jre/lib/endorsed directory:
- serializer.jar
- xalan.jar
- xercesImpl.jar
- xml-apis.jar
If the endorsed directory is not present in <JAVA_HOME>/jre/lib, create a new directory and name it endorsed.

Procedure

In the <INSTALL_DIR>/bin directory, invoke the following command:
- updateJDK.cmd REPLACE <path to new JDK>
- updateJDK.sh REPLACE <path to new JDK>
where,

<path to new JDK> is the location of the new version JDK.
The updateJDK REPLACE command performs the following tasks:
- moves the existing JDK from <INSTALL_DIR>/jdk to <INSTALL_DIR>/jdk_<timestamp>
  where,
  
  <timestamp> is the time when jdk_<timestamp> is created.
  
  If you want to restore the old JDK for any reason, you can locate the directory at <INSTALL_DIR>/jdk_timestamp.
- copies <path to new JDK> to <INSTALL_DIR>/jdk.
- copies the following jar files into <INSTALL_DIR>/jdk/jre/lib/endorsed:
  - serializer.jar
  - xalan.jar
  - xercesimpl.jar
  - xml-apis.jar
To verify the Java version that Sterling Call Center is using, go to the <INSTALL_DIR>/bin directory and run the ./setupfiles.sh command for Linux or the setupfiles.cmd command for Windows.
