Prepare lockbox files for Java upgrade
Before changing the Java version of a node that is running the VxFlex OS Gateway or
AMS of VxFlex OS v2.5 or later, you must prepare lockbox-related files.
About this task
The lockbox in VxFlex OS v2.5 saves files in the Java folder of the VxFlex OS Gateway
and the AMS. These files need to be saved before any Java version update, then
pasted back into the folder.
Procedure
1. From the
java\jre<VERSION>\lib\ext

java/
jre<VERSION>/lib/ext
(for Linux) Java folder, copy these files to a
different folder:

2. Update the Java version.
3. Paste these files back to the folder from where you copied them.
