About Java JRE support
The Java LiveUpdate (JLU) agent requires that a minimum version of Java JRE 1.4.2 be installed. NetBackup delivers a Java JRE that meets or exceeds this minimum requirement for most UNIX platforms.
NetBackup does not deliver Java JRE for the Linux IBMpSeries platform. For this platform, the NetBackup installation script attempts to detect an acceptable version of Java JRE. If an acceptable version is detected, the appropriate links are created. If an unacceptable version is detected, the script notifies you.
If the script does not detect Java JRE or an acceptable version of it, you must install Java JRE manually before you install NetBackup. After you have installed Java JRE 1.4.2 or later, you can install the NetBackup client software.
Some NetBackup LiveUpdate versions are not supported for use with some Linux IBMpSeries and IBMzSeries systems. The following table describes which NetBackup LiveUpdate versions can be used on these systems.
Table: Supported versions of NetBackup LiveUpdate for IBMpSeries and IBMzSeries systems
System | Supported in NetBackup 6.5 and 7.0 | Supported in NetBackup 7.0.1 | Supported in NetBackup 7.x |
|---|---|---|---|
IBMzSeries RedHat | No | Yes (see Note 1) | Yes (see Note 1) |
IBMzSeries SUSE | No | Yes (see Note 1) | Yes (see Note 1) |
IBMpSeries RedHat | Yes (see Note 2) | Yes (see Note 2) | Yes (see Note 2) |
IBMpSeries SUSE | Yes | Yes | Yes |
Note 1
Java JRE is delivered with NetBackup for IBMzSeries systems. Under certain conditions, the following error and failure may occur when you upgrade NetBackup clients:
Oct 13, 2010 1:00:37 AM Trying to load jar file from /tmp/ 1286949636653/cryptix-jce-provider.jar Oct 13, 2010 1:00:37 AM IdsEncodingFailed Oct 13, 2010 1:00:37 AM JLUException Nested Exception is: [ java.security.InvalidKeyException ] Illegal key size or default parameters
To correct this problem, you must first install
"unlimited strength jurisdiction policy files"into your NetBackup Java JRE. NetBackup does not deliver Java JRE with these files. They must be downloaded from the IBM website and installed manually in your NetBackup Java JRE location.Next, perform the NetBackup client upgrade procedure again. This upgrade also reinstalls the NetBackup LiveUpdate agent.
Note 2
Before you can use NetBackup LiveUpdate on IBMpSeries RedHat version 4, you must first install IBM JRE version 1.6.
