Enterprise Manager Cloud Control 12c Release 4 (12cR4) Articles

I’ve started to play around with Enterprise Manager Cloud Control 12R4. The clean installations on Oracle Linux 5 and Oracle Linux 6 were really easy. You can see how I did them here.

I used as the database repository. I’ll probably have a go with a 12c database in future, which is now supported, but my main focus this time was to check out something similar to what I have at work. Forgive my caution, but I’ll not be using 12c database for my EM repository for a while yet. Cloud Control is too important to risk…

I wasn’t going to bother with an upgrade article because  wrote a good blog post about the upgrade here. Whilst going through the upgrade, there were a few things I needed to make extra notes on, since I have an terrible memory, so it ended up as a separate article.

Ultimately, you are going to need to read the upgrade docs because there are lots of caveats to think about, depending on what options you use.

Previous upgrades at work were a pain, but we had a more complicated installation with multiple management servers and a separate database. More recently we switched to running a simple configuration (DB and OMS on the same server) on an Oracle Linux VM. That makes doing a trial run of the upgrade at home a more realistic test. Whether it’s an improved Cloud Control upgrade process or the fact this is a single machine setup, the upgrade was really easy. Now that I’ve practiced the upgrade at home, I’m feeling relatively confident doing the upgrade in production. I’ll probably leave it until I get back from Bulgaria (BGOUG). It’s not really fair to change everything and then leave the country… 🙂
