Updating Java in NetBackup

These are my notes on updating the embedded Java in NetBackup. The Symantec NetBackup patches can't keep up with the Java security patches from Oracle. The way to get around this is to use the Java installed on the server instead of the embedded Java in NetBackup. Sometimes System administrators will just link the embedded program to the system program, this is not what I'm doing here. It is similar though, the fix I'm explaining here is supported by Symantec. The examples I give on this post are from a Solaris 10 (x86) server, but the steps below will work on any server that NetBackup runs on. The embedded Java is installed on all NetBackup servers and clients.

First we need to find all the java on the server. Running the commands java -version or which java is not enough. These commands only show the main Java on the server, as shown by the examples below. # java -version
Java version "1.6.0_33"
Java(TM) SE Runtime Environment (build 1.6.0_33-b03)
Java HotSpot(TM) Server VM (build 20.8-b03, mixed mode)
# which java
/usr/bin/java

Use the find command to find all the Java on your server. # find / -name java -type f
/usr/jdk/instances/jdk1.6.0/bin/amd64/java
/usr/jdk/instances/jdk1.6.0/bin/java
/usr/jdk/instances/jdk1.6.0/jre/bin/java
/usr/jdk/instances/jdk1.6.0/jre/bin/amd64/java
/usr/jdk/instances/jdk1.5.0/bin/java
/usr/jdk/instances/jdk1.5.0/bin/amd64/java
/usr/jdk/instances/jdk1.5.0/jre/bin/java
/usr/jdk/instances/jdk1.5.0/jre/bin/amd64/java
/usr/openv/java/jre/java
/usr/openv/java/jre/amd64/java
The last two lines in the above example are the embedded Java in NetBackup.

To find out what version of Java is on the server. Put the path statements above into the terminal with  -version at the end. Like the example below.
# /usr/jdk/instances/jdk1.6.0/bin/java -version
Java version "1.6.0_33"
Java(TM) SE Runtime Environment (build 1.6.0_33-b03)
Java HotSpot(TM) Server VM (build 20.8-b03, mixed mode)

Open the .nbjConf in your favorite editor. # vi /usr/openv/java/.nbjConf
Change the JAVA_PATH to: JAVA_PATH=/usr/jdk/instances/jdk1.6.0/jre/bin/java
If NetBackup uses a different version of Java then the Java installed on your system it will still work for the client. I have tested this with NetBackup 7.1, which was using java 1.6.0_26, and set it up to work with Java 1.5.0_36. The Media server and the Master server need to have the same version of Java in order to work though.

Test Nebackup by performing a backup. If there are no errors then delete the two embedded Java files for NetBackup.
