Oracle Database 12c Release 2 (12.2): Installation Articles

If you follow me on social media, you will know I’ve put out a few 12cR2 installation articles recently. It’s good motivation for me to read through the installation guides and see what’s changed, if anything, between versions. I quite like doing some of this nuts & bolts stuff. 🙂

If you’re interested, this is what I’ve done so far.

I always feel like I should stress a few things in relation to my install guides, or anyone else’s for that matter.

  • You should always read the installation manuals. I know it can be boring, but there is a bunch of stuff you should understand that I don’t include, because my intention isn’t to regurgitate the manual. Maybe you have a situation where something is relevant that other’s don’t care about.
  • The RAC articles are intentionally really basic. I avoid some of the job separation (users and groups) that you may want in your organisation. I keep the storage very simple. I avoid a lot of the possible topology variations. I would always consider these as a starting point for playing with RAC on a VM, rather than something you would consider a RAC “best practice”. Once you’ve got one of these running you can try variations. Don’t expect me to write a separate guide for all variations. Try it yourself.
  • I will make choices over my approach to make stuff suit the wider audience. For example I’ve tended to steer clear of ASMLib and the new “ASM Filter Driver” because a big chunk of my audience are sceptical of them and prefer to use UDEV. I’m happy to use either and if you are using Oracle Linux and UEK it really doesn’t make a great deal of difference. I think you should play with both and decide for yourself which you like. Remember, I’m not going to write multiple variations of the article.
  • The installation guides are all using interactive installations, but I rarely do these nowadays, preferring to use silent installations and silent database creations. I’m not sure how many people would be happy with a bunch of response files as their introduction to a new version. I think the GUI screens aid with understanding when you are new. You should definitely graduate to the silent stuff though! I’ve included the response files generated during each interactive installation.
  • I modify the installation guides over time as I learn more about the stuff. That’s true of all my articles, but don’t assume because I installed it this way today, that’s definitely the way to do it!

I guess what I’m saying is I’ve only done a handful of 12.2 installations, so I’m no guru. Keep that in mind and learn to think for yourself! 🙂

Happy installing!
