You can manually upgrade the Java Runtime Environment (JRE) for the Commvault software.



The Commvault software is deployed with a long term support release of the JRE. If a newer version of the JRE than the one deployed by the Commvault installer is required, you can manually upgrade it using the procedure described below.



  1. Identify the JRE version to be installed. You must only upgrade to a more recent security or patch version of the currently installed JRE. Do not upgrade to a newer minor or major version, because that is very likely to cause breakages. For example, if JRE 11.0.1 is installed, you can upgrade to 11.0.5, but not to 11.1.0 or 12.0.0.
  2. Go to
  3. Download the OpenJDK file as follows: • Windows: Download the ZIP file. Do not download an MSI file. • UNIX or Linux: Download the tar.gz file.
  4. On the system where you plan to apply the upgrade, stop Commvault services.
  5. Back up and then remove all contents of the current Commvault JRE folder, located at commvault_contentstore_installation_folder\jre.
  6. Extract the contents of the ZIP or tar.gz file to a temporary location, and then move or copy the new JRE contents into the (now empty) Commvault JRE folder.
  7. Verify that subfolders such as \bin and \lib are directly under the Commvault JRE folder.
  8. Start Commvault services.

If any issues are encountered, restore the original version of the JRE that you backed up in Step 5, above, or use the Commvault install media to perform a repair operation.
