The ‘oracle-validated’ package can very well be used to validate node properties.

The primary function is an easy way to prepare a linux system, but it has exactly what you were looking for: checks!

Alex,

The documentation says to install a bunch of RPMs, create users, modify kernel parameters, etc.

3 ways to do it:
1) Manually
2) Write a script to automate the issue
3) RDA -T hcve (which should do all the checks according to Metalink)

Option #3 seemed the easiest.

Of course if a certain development team will add prerequisite checks to a certain monitoring tool – I’ll use that instead :)

Chen, why do you use RDA for pre-requisites check? I see it second time and I was sure that using RDA for that is not what installation guide says. On the other hand, it’s been a while I put my nose inside install guide. :)

Joel,

I’m not sure what you mean – Cloning is fully supported and documented. Turning RAC into stand alone is fully supported and documented. Installing important packages after their lack was discovered is certainly not recommended, but is never a big issue.

What is the problem, then?

I have long been against this kind of cloning, for the simple reason that I don’t trust every node to be configured exactly the same. Adding in a big difference like rac to standalone isn’t going to help matters. There is value in being supported, even if businesses can’t evaluate it correctly. If the word “production” is involved, mulish is a virtue, don’t take shortcuts, creativity is a negative.

Can’t say as I trust RDA to think for me either. It’s a good tool for what it does.

It’s all like going down stairs without looking where you are stepping, just because the stairs seem standardized everywhere you’ve been. That last one can be a doozy, even if you’ve re-tied your shoes.
