Java & patching on Linux Redhat
Posted on 2012-12-20
I'm trying to work on a stable patching solution for RHEL, all version. One of the things I'm running into is jre patching. Generally, jre when installed is linked to /usr/bin/java. But developer sometimes install their own java version and in their or directory path, where ever that is, and call it via full path from their app. Sure enough, i want to make sure that I one, don't break an app, and 2 don't resolve a security or vulnerability issue because I didn't address all the java versions. Do you have a good way, script, something, that can help me figure out where Java is installed all over my systems, identify the version, and maybe even help upgrade said found version? I know how stupid this question might sound, but it was asked of me and I really can't come up with a clear cut solution. Please help.
