The ORACLE-BASE Blog – Oracle 11gR2 RAC On Linux Using VMware Server 2

11gR2 RAC feels very different to 11gR1 RAC. I can imagine quite a few people wanting to upgrade from 11gR1 thinking it will be trivial and getting a rude awakening…

The Grid Infrastructure (Clusterware + ASM) seems more complicated. There are more installation options, more prerequisites, more background processes and a bigger memory requirement…

I typically install 11gR1 RAC on VMware using 1G of RAM per VM. If you try that with 11gR2 you will get to the end of the Grid Infrastructure installation and have nothing left. The minimum recommendation for Grid Infrastructure alone is 1.5G, but if you want the RAC DB as well you are talking 2.5G. It actually worked fine with 2G of RAM allocated to each VM, but this is a whopping increase compared to 11gR1.




At this point I feel like I know nothing about 11gR2 RAC, but it certainly doesn’t feel like a patched version of 11gR1. If this had been released as 12g I would have still have been surprised by the level of change.

So over the next few days I’m expecting the dust to settle, my residual fear of all things new to subside and I’ll probably change my opinion completely and think it’s all the same as it was before…
