RE: Jan 2015 JVM PSU

Creating a database from the standard template, of course, results in the database having JVM.

It is also risk disabling the JVM after the install.

Some export-import notes relating to JVM in the database are 460748.1, 1017276.102, 10191927.1, 1435388.1

Particularly important when you have to support multiple versions (8i to 12c) of Oracle.

Not testing all of your processes - which should discover dependencies - is a bad idea. Not installing unneeded components is definitely a good idea. (Also a requirement for some more stringent audits and certifications.)

I have never encountered data pump export being dependent on the JVM. The only export oddity I've run into is TTS exports pre-11.2.0.3 will fail of xmldb is not installed - but this is not a dependency it's a bug. There's a workaround (exclude=xmlschema) and patches available to fix it. Dependencies should be documented as such; if you find a "dependency" which is not documented then you should be opening a bug against it so that it will either get acknowledged as an explicit dependency and documented, or it will get fixed. That sort of thing is a very obvious bug report since it's so easily reproducible.
