Oracle Cloud Control 12cR2 is installed and merrily monitoring one of the test 11gR2 databases running on HP-UX. I’ll probably leave it like that until I come back from Oracle OpenWorld. I don’t want to change the entire administration and monitoring infrastructure just as I leave for a couple of weeks.
As I’m re-familiarizing myself with the 12c way of doing things, I’ve been wondering if this really is a full “Release 2″ product, or just 12cR1 with Bundle Patch 2. Not surprisingly, one of my readers asked the same question, pointing out the version 22.214.171.124 does not look consistent with a “Release 2″ product, which would typically be 126.96.36.199.
I take Oracle version numbers with a pinch of salt. I’m currently using WebLogic version 10.3.5, which is 11g WebLogic. At least WebLogic 12c has been versioned appropriately.
So why the 12cR2 branding, when 12cR1 of the database hasn’t been released yet? My guess is this is a marketing move for one very specific reason. One of the big marketing messages around Cloud Control was its ability manage clouds and allow you to charge customers based on their resource usage. While speaking recently to a representative of a large oracle customer/partner, I found out this functionality plain didn’t work, at least not with their selection of (latest version) Oracle products.
Assuming Cloud Control 12cR2 is now actually capable of delivering on this promise, that represents quite a big change that’s probably worthy of a re-brand, even if the version number doesn’t warrant it.
Of course, this is all speculation on my part. I’m not using it for managing clouds or charging customers. I’m just a regular DBA who likes to watch the performance page every few minutes while doing my administration in SQL*Plus.
Update: See Hans’ comment about the version number. He’s quite correct that this version falls in line with a new release in the GC/CC universe.
I did an EM Cloud Control 12cR2 installation at work yesterday. The database repository was 188.8.131.52 on HP-UX and the middle tier was installed on RHEL 5.8. The installation was pretty much the same as the 12cR1 version. Over the next few days I’ll be testing out some of the features to decide if we can move across to it permanently.
Today I did two run throughs of single server installations on Oracle Linux 5.8 and 6.3. There are a couple of minor differences, but nothing to worry about. You can see what I did here:
The installations are a little small, so they are not too fast, but it’s good enough to test things out.
Update: It’s been a while since I used the 12c version, so I’ve had to relearn a few simple things. I thought I might as well write the down in case it helps others.
Enterprise Manager Cloud Control 12c Release 2 was released a couple of days ago for all the major platforms. That in itself is not news any more, but the fact we are going to trial it at work as a replacement for our 11g Grid Control installation is.
It’s in my low priority task list, so I’m not sure I’ll get it all sorted before OOW12, but it is something to look forward too. I know it’s tragic, but I’m quite excited.
Question: What happens when 12c Cloud Control runs out of disk space?
Answer: It doesn’t work very well.
I have a 12c Cloud Control installation on an Oracle Linux 6.1 VM and I was pushing an agent to both nodes of an 184.108.40.206 RAC, also on OL6.1 VMs. The agent installation seemed to go fine and the agent upload to CC was fine, but when I tried to discover the database on the nodes it went a bit loopy. After a little messing about I noticed my disk was maxed out on the 12c CC server. Bummer!
So I turned off the VM, added another virtual disk, turned it back on and added the new disk to the existing volume. Bob’s your uncle!
Once Cloud Control was running the database discovery worked fine and it was full steam ahead.
Before I realized my mistake I was starting to think this was OL6.1 related, but as it stands I’ve still seen no ill effects of running Cloud Control or RAC on Oracle Linux 6.1.
I mentioned the day before Open World I put a Virtual RAC on Oracle Linux 6.1 article live. Although the procedure was complete, some of the screen shots were from an old article as I didn’t have time to redo them before my flight. I’ve just run through the procedure again and taken new screen shots. As a result, I’ve allowed the article to display on the front page of the website, which is why you will see it listed as a new article there.
This kinda rounds out the whole Oracle on 6.1 stuff as there has been a single instance installation guide out for ages and more recently the Cloud Control installation, which references it.
Remember, it’s still not certified yet, but it’s coming.
Update: It’s finally certified. See here.
While I was at Open World I tried a few times to get hold of the new Cloud Control software, but the hotel network wasn’t up to the job, so I had to wait until I got home.
The installation is pretty simple compared to previous versions of Grid Control and it installs fine on both Oracle Linux 5.x and 6.x. As always it’s a little greedy on the memory front, with the recommendation for a small installation being 4G for the Cloud Control and 2G for the repository database. That’s not including the OS requirement. On the subject of the repository database, you can use a number of 10g and 11g versions, but anything before 220.127.116.11 requires additional patches, so I stayed with 18.104.22.168.
