I am running a server with a global zone and four local zones. The global zone provides the database server, and the four local zones run instances of Tomcat with a client application (different one per zone).
When I built the server, I installed Java 1.6 on the global zone, then created the local zones - so they all have Java 1.6 on them.
Now I need to upgrade to Java 1.8. I have done this on another Solaris server with no zones and have had no problems, but I am wondering how to handle the zones with the upgrade.
I plan to upgrade Java on the global zone, but what about the other zones? I require Java 1.8 on all the zones, which is why I'm upgrading the global zone.
What I'm asking is how to manage the upgrade with the other zones. Do I shut them down first? Are there commands to propogate the new Java version to the other zones once the global zone is done?
I've searched but so far have come up empty. Thanks to all for assistance.
