About the NetBackup Java Runtime Environment
Veritas installs a customized version of the Java Runtime Environment (JRE) when you install any of the products shown. The customized version of JRE does not include all the directories that a standard JRE installation includes, such as man and plugin.
Products that install the JRE:
NetBackup master server, media server, or UNIX and Linux client software
NetBackup Java Remote Administration Console
OpsCenter Server or View Builder
Starting with NetBackup 8.3, the Java GUI and the JRE packages are optional for Linux and Windows media servers and UNIX and Linux clients.
As with previous releases, the Java GUI and JRE packages are installed automatically on all master servers because they are required. The Java GUI and the JRE are not part of the default installation on Windows clients. Install the Java Remote Administration Console if you require this functionality on your Windows clients.
The various NetBackup installation methods allow the user the choice to install or not install the Java GUI and JRE packages. More information about installing or removing the Java GUI and the JRE after install or upgrade is available.
See Add or Remove Java GUI and JRE after install.
Previously, the JRE package that is installed with NetBackup or OpsCenter was only updated when you upgraded to a later release of either software. You can use the nbcomponentupdate utility to update the JRE to a supported version for the products shown:
NetBackup master server, media server, or UNIX and Linux client software
NetBackup Java Remote Administration Console
OpsCenter Server or View Builder
Note:
You cannot use this utility to update the JRE for the NetBackup Plug-in for VMware vCenter.
If your system is running NetBackup 8.0 or later, use Table: Location of JRE update utility to determine the location of the nbcomponentupdate utility.

NetBackup Commands Reference Guide
The NetBackup installed version of the JRE is the supported major version for that NetBackup release. Use this utility to update to a minor version of the supported major JRE version. For example, if NetBackup 8.0 installed JRE 1.8.0.31, the supported major version is 1.8. Use this utility to update to JRE 1.8.0.92.
Veritas recommends that you update to another major JRE version only if the JRE vendor declares an end-of-life for the installed JRE version. If the JRE vendor declares an end-of-life for JRE 1.8, which is also the installed JRE version in your environment, update to JRE 1.9.
Close the product, such as NetBackup, before you attempt to update the JRE. If the product is active when you attempt the update, the utility exits with an error message that requests you to close the product.
Caution:
Do not stop the utility while the JRE update is in progress. This action can cause the product that uses the JRE, such as NetBackup, to become unstable.
If there are additional versions of the JRE installed on your system for other applications, the NetBackup JRE does not interfere with them. The NetBackup JRE does not provide integration with web browsers and does not allow Java Applets or Web Start to run. For that reason, the NetBackup JRE cannot be used in a browser-based attack that uses Java Applet or Web Start vulnerabilities.
