Enterprise Manager Cloud Control 13.3 Silent Upgrade

A few days ago I put out a post called Enterprise Manager Cloud Control 13.3 Vagrant Build. In a comment on that post Dinesh said,

“Would like to see the silent upgrade from oem12c to oem13c upgrade post from you”

I normally try to keep on top of upgrades, so I’ve never done a jump bigger than one version, but I was checking through the documentation, and assuming it’s a supported start version, there isn’t much difference between the upgrades from most versions, so I thought I would give it a go. As I mentioned in the last post, I already had a GUI upgrade article.

I didn’t have a silent upgrade though. I do now. πŸ™‚

In order to try this out I did a Vagrant build of Cloud Control 12cR5, to give me an easy way to get a clean starting point. You can see that here. If you want to practice the upgrade, it’s a really easy way to do it.

I’ve left the agent upgrade using the Cloud Control interface, but there is an example of how to do it silently using WLST here. It’s pretty simple.

So not only did I not expect to be writing that post a few days ago, but I certainly didn’t expect to be writing this one. πŸ™‚

Enterprise Manager Cloud Control 13.3 Vagrant Build

A little short of a year ago I knocked up a Vagrant build to prepare an environment for practising Cloud Control 13.3 installations and upgrades. This just automated the creation of the environment and installation of the database, ready for me to start playing around with the Cloud Control bit. At the time I released these articles.

I didn’t mention anything about the Vagrant build as it didn’t do much more than build the database, so it didn’t seem worth mentioning. It was just a convenience for me.

More recently someone pointed it out on Twitter and I made a note to myself to “finish it off” and make it do a full silent build, then kind-of forgot again.

A few days ago I had a self-induced problem with our Cloud Control server, and I realised I didn’t have the best plan of action for a complete rebuild scenario. I had backups, so I didn’t need to do a rebuild, but that doesn’t stop me wanting to be able to do it, so I did the following things…

I scripted a silent build of the work environment we use. I put together a general article to show how to do a silent build of a simple installation too. If you’re interested you can see it here.

I wrote some EMCLI scripts to do most of the tasks I needed for a complete rebuild. We already use EMCLI for some of the stuff, like jobs, but I filled in the gaps where I had been a bit lazy. Those are all checked into a company Git repo, and they are quite specific to what we need, but there are some basic EMCLI examples available here, if you are interested in getting into EMCLI.

Finally, I made my Vagrant build a fully automated Cloud Control 13.3 build on Oracle database 18c. According to the certification matrix, Oracle 19c is not yet certified for the repository database (but someone on Oracle-L said this certification is imminent). If you are interested in playing around with Vagrant, you can find it here. I’ve managed to get away with 6G of memory, but that makes it chronically slow. The more memory you can throw at it the better. πŸ™‚

I didn’t really expect to be revisiting this stuff a year down the line, but it was born out of necessity, or at least necessity for my peace of mind. πŸ™‚

Oracle Enterprise Manager Cloud Control 13c Release 3 (13.3.0.0) Upgrade

A few months ago I wrote about the installation and upgrade Oracle Enterprise Manager Cloud Control 13c Release 3 (13.3.0.0).

At the time I did a clean install and an example upgrade from 13.2 to 13.3. The idea behind the upgrade was basically to practice what I needed to do at work.

Just before I left for OpenWorld I got our virtualization folks to give me a clone of the production Cloud Control VM and I ran a practice upgrade on that. It’s important to do a “real” run through, as sometimes you hit issues you don’t see when upgrading from a clean installation of the previous version. In the past the upgrade of the clean installation of the previous version has worked fine, but the real upgrade failed the prerequisite checks as some of the agents or plugins were too old. The latest test on the clone worked fine, so we had the green light to do the production upgrade.

Post OOW18, my first job on returning to work was to get Cloud Control upgraded. I repeated the process I had done on the clone and it went fine.

In a funny coincidence, while I was doing the upgrade someone retweeted the blog post from a few months ago. Weird.

As a reminder, here are the 13.3 articles.

Oracle Enterprise Manager Cloud Control 13c Release 3 (13.3.0.0) : Installation & Upgrade

Cloud Control 13c (13.3) was released a few days ago, but from what I can see the documentation hasn’t been made available yet (see update). Despite this I had a go at installing it using the instructions for 13.2, and with a couple of small exceptions it was similar, which wasn’t surprising.Β The upgrade from 13.2 to 13.3 was similar to the previous upgrade from 13.1 to 13.2 also.

I’ve added a couple of articles to the website.

These articles are in no way a replacement for reading the manuals (if there were any), but it will hopefully give you a feel for how easy it can be to get going with Cloud Control.

For the installation article I did the basic setup of the box and the DB using Vagrant. You can repeat the build using my Vagrant setup here if you like.

Note. I used a different database version for the upgrade article to more closely match what I have at work. This was basically a trial run for a work upgrade, although that will probably not happen for a few months because of other priorities.

I will revisit both articles once I get eyes on the documentation. πŸ™‚

Cheers

Update: Thanks to Peter in the comments whoe found the docs here.
