So, I am in a major friggin' quandary. Any post to get to use the word quandary. Anyway support recommends I upgrade to 11.5 since one of my computers can't connect to the database on 11.1.2. But, do I wait until v12 is out and just not be able to connect from Computer 1. It seems silly to do the whole upgrade thing, then have to do it again in less than three months. But I don't want to have to use a workaround on computer one that is dangerous the whole time.
