After having a play with Oracle 12c on Windows 8, I decided to give Windows Server 2012 a go. Here is the resulting virtual RAC installation.
As you would expect, much of the process is pretty similar to the 11gR2 RAC installation on Windows 2008.
Windows Server 2012 is a strange beast. The interface is quite similar to Windows 8, which seems strange for a server OS. I’m gradually coming to terms with the Windows 8, so I am not so repulsed any more. That’s not to say I think it is the correct thing for Microsoft to do, but the thought of supporting my family on it is not filling me with quite so much dread now.
I really should get round to upgrading my desktop to Fedora 19, but time has been short.
I finally got my server problems sorted out yesterday, so I was able to do a 12c virtual RAC installation. You can see what I did here:
The setup is pretty much the same as the 11gR2 setup. So there’s no real drama at all.
With the basic installation articles out of the way I can start having a play with the functionality.
I’ve now got 12c running under VirtualBox on my server (Oracle Linux), desktop (Fedora 18), laptop (OS X) and desktop at work (Windows 7). If I can just get it running on my Nexus 4 and Nexus 7…
My initial batch of 12c installations resulted in these two articles.
Judging by my web stats, they’ve proved very popular. According to Google Analytics, there are 3-4 active visitors on them pretty much 24×7.
My progress from there has been thwarted somewhat by technical issues. The server I normally use for my Virtual RAC installations is being a little funky at the moment. Rather than mess about I figured I would just reinstall the base OS. Initially it was running Fedora 18, but I decided to go for Oracle Linux instead. This server is used entirely for running VirtualBox VMs, so stability is more important than being bleeding edge. My desktop is still Fedora though.
The Oracle Linux install was fine. The 6.4 spin of Oracle Linux detected all my hardware, including the RAID stuff, and it installed with no worries. The problem is getting all the VMs back on to it from my backups. It’s taking an age!
Hopefully tonight, or tomorrow I can get back on the case with the 12c RAC installation. Yury from Pythian has already done a run through, which you can see here. There doesn’t seem to be much difference to the infrastructure setup compared 11gR2 RAC, which is good.
As promised in a recent post, I’ve updated the Oracle 11gR2 RAC on Oracle Linux 5 article. It now uses VirtualBox 4.2.6, rather than 3.2.8 as it was before, and Oracle Linux 5.8.
I’ve purposely left it as an 126.96.36.199 installation as you can get this from OTN without needing access to My Oracle Support (MOS). The process works just as well for 188.8.131.52 and I would recommend you use that if you do have access to MOS. Remember, if you are doing the RAC installation on Oracle Linux 6 you are going to need 184.108.40.206, so OL5 might be the right option if you are playing around with this at home with no access to MOS.
I spent today updating my Oracle 11gR2 RAC installation on OL6 article. The original article used an older version of VirtualBox , which meant some of the screen shots looked a little dated. It’s now updated to VirtualBox 4.2.6, so it should be a little less confusing for anyone who is new to VirtualBox.
I’ll probably update the OL5 RAC article some time this next week, since that article uses VirtualBox 3.2.8, which is pretty much ancient history now.
Followers of my blog know I like doing virtual RAC installations.When I do these I’m focusing very much on the Oracle side of things, leaving the virtualization tool to handle the hardware virtualization, like networking and shared disk.
A few weeks ago Gilbert Standen contacted me to say he had done a virtual RAC installation using OpenvSwitch to virtualize the network components. He posted some basic tips. When I mentioned it on G+ and twitter, it generated some interest, so I suggested he write it up with a little more detail. That process has started now on his blog. You can see the first couple of articles here:
He tells me he’ll be adding more details to the posts when time permits.
If you are more focused on the network side of the infrastructure stack I think this is a really interesting proposition and well worth a read.
Some time ago I wrote an article about configuring DNS for the SCAN address in Oracle 11gR2 RAC.
Over the last couple of days one of the Oakies has given me some feedback on the article based on his experiences with Oracle Linux 5.
For my virtual RAC installations I typically do the DNS configuration on the host machine, which is running Fedora. It seems Oracle Linux 5 is a little different. Just to make sure I ran through the setup on Oracle Linux 5 and 6 to see what the score was.
Oracle Linux 6 is pretty much the same as Fedora as far as installation and configuration of BIND is concerned. Oracle Linux 5 (and also RHEL5 I assume) is a little funky in that it doesn’t create the default config files automatically. There are sample files you can use, but they contain a load of crap you don’t need and are missing some stuff you do. The easiest way to get it configured is to install the “system-config-bind” package and start the GUI. This notices you have no config and sets it up for you. You can then exit the GUI and do the manual config as described in the article. Very odd.
I’ve made a note about this in the article, so it shouldn’t trip anyone else up. I’ve also given some examples of the manually adjusted default named.conf files for each distro.
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.
It’s all a bit last minute, but today I decided to do an Oracle 11gR2 (220.127.116.11) RAC installation on Oracle Linux 6.1 using VirtualBox. The 18.104.22.168 patch has fixed all of the installation issues related to RAC on OL6.1, so it was pretty smooth. The procedure can be seen here.
As noted in the article, the screen shots of the GI and DB installers are from an 22.214.171.124 article. I’ll update these screen shots when I get back from OpenWorld. Like I said, it was all a bit last minute. Normally I wouldn’t put an article like this live (and you can see it’s not on the homepage yet), but I get lots of questions about this subject, so I thought I would make it available to make my life easier.
PS. There is no suitable oracle-validated package available for this at the moment, so the prerequisites have to be done manually.
As I’ve mentioned before, I’ve kinda ignored the fact that any operating system other than Linux (specifically Oracle Linux) exists. It’s quite easy to do when you are working with Oracle products and you get to choose your own environment.
As a vague nod to the fact that Windows does actually exist, I’ve finally got round to updating my Windows virtual RAC article.
Windows 2008 is an unusual operating system in some respects. The RAC installation is pretty simple really, but finding some of the config dialogs is a complete nightmare. Chains of menus, dialogs, buttons and hyperlinks to get you to the dialog you need. What’s worse, some of the menus are hidden unless you remember to “Alt” or “Alt+N”. Crazy! If I was using Windows on a regular basis I think I would just memorize all the dialog program names and start them directly from the Run menu. It’s got to be easier than traversing that nightmare. I remember when Windows was considered the easy option. It doesn’t feel like the case anymore.
In related news, yesterday I got an invite from Jeremy Schneider to help out at RAC Attack at OOW 2011. That should be fun. See you there!
