Oracle 188.8.131.52 is out, after lots of announcements the product has finally been released. I had just extended my 184.108.40.206.3 cluster to 3 nodes and was about to apply the July PSU when I saw the news. So why not try and upgrade to the brand new thing?
What struck me at first was the list of new features … Oracle’s patching strategy has really changed over time. I remember the days when Oracle didn’t usually add additional features into point releases. Have a look at the new 220.127.116.11 features and that would possibly qualify to be 12c Release 2…
In summary the upgrade process is actually remarkably simple, and hasn’t changed much since earlier versions of the software. Here are the steps in chronological order.
I don’t know how often I have type ./ruinInstaller instead of runInstaller, but here you go. This is the first wizard screen after splash screen has disappeared.
Naturally I went for the upgrade of my cluster. Before launching the installer though I made sure that everything was in working order by means of cluvfy. On to the next screen:
I always install English only. Troubleshooting Oracle in a different language (especially if I don’t speak or understand) is really hard so I avoid it in the first place.
Over to the screen that follows and oops-my SYSDG disk group (containing OCR and voting files) is too small. Bugger. In the end I added 3 new 10GB LUNs and dropped the old ones. But it took me a couple of hours to do so. Worse: it wasn’t even needed, but proved to be a good learning exercise. The requirement to have that much free space is most likely caused by the management repository and related infrastructure.
Back to this screen everything is in best order, the print screen has been taken just prior to the change to the next. Note the button to skip the updates on unreachable nodes. Not sure if I wanted to do that though.
I haven’t got OEM agents on the servers (yet) so I’m skipping the registration for now. You can always do that later.
This screen is familiar; I am keeping my choices from the initial installation. Grid Infrastructure is owned by Oracle despite the ASMDBA and ASMADMIN groups by the way.
On the screen below you define where on the file system you want to install Grid Infrastructure. Remember that for clustered deployments the ORACLE_HOME cannot be in the path of the ORACLE_BASE. For this to work you have to jump to the command line and create the directory on all servers and grant ownership to the GI owner account (oracle in this case, could be grid as well).
Since I like to be in control I don’t allow Oracle to run the root scripts. I didn’t in 18.104.22.168 either:
In that screen you notice the familiar checking of requirements.
In my case there were only a few new ones shown here. This is a lab server so I don’t plan on using swap, but the kernel parameter “panic_on_oops” is new. I also didn’t set the reverse path filtering which I corrected before continuing. Interestingly the installer points out that there is a change in the asm_diskstring with its implications.
One thing I haven’t recorded here (because I am using Oracle Linux 6.5 with UEK3) is the requirement for using a 2.6.39 kernel – that sounds like UEK2 to me.
Update: my system is Oracle Linux 6.5, not Red Hat. See Sigrid’s comments below: for Red Hat Linux there doesn’t seem to be a similar requirement to use UEK 2, which matches the documentation (Installation guide for Grid Infrastructure/Linux).
Another interesting case was that the kernel_core pattern wasn’t equal on all nodes. Turned out that 2 nodes had the package abrt installed, and the other two didn’t. Once the packages were installed on all nodes, the warning went away.
Unfortunately I didn’t take a print screen of the summary in case you wonder where that is. I went straight into the installation phase:
At the end of which you are prompted to run the upgrade scripts. Remember to run them in screen and pay attention to the order you run them in.
The output from the last node is shown here:

Did you notice that TFA has been added? Trace File Analyzer is another of these cool things to play with, it was available with 126.96.36.199 and as an add-on to 188.8.131.52.
Back to OUI to complete the upgrade. After which cluvfy performs a final check and I’m done. Prove it worked:

In another post I’ll detail the upgrade for my databases. I am particularly interested about the unplug/plug way of migrating…
