Highly Productive Weekend – meh?

It’s the designated Quarterly Maintenance weekend for my day job though not all that much I had to assist with since I’m only 50% on the sysdba team. So since I was sticking around for the weekend and there really isn’t all that much to do otherwise while my wife worked I took the time to get Oracle RAC setup in my home server environment again. My previous install was blown away quite a while back to make room for other cool projects.

This time around the entire install was based upon the latest release (11.2.0.3) of the Grid Infrastructure and Database. Also this time around I setup the Xen guests as paravirtualized (pv) rather than full (hvm) and used CentOS 5.7 rather than Oracle Enterprise Linux. I hadn’t had experience setting up OEL as a pv but last Fall found a slick way to install CentOS. I’ll miss out on things such as ACFS but I have no desire to use ASM as a LVM (probably since the shared disk I use for ASM is essentially LVs over iSCSI – you can only virtualize so much before it’s pointless -no?)

Overall the entire setup was quite easy. Using open-iSCSI on the guests was the only real thing different from my 11.1 RAC installs. It seems like each RAC install since 11.2 has really been improved and has become quite flawless. I have no real use case for RAC but at least I have a recent setup around again to play around with.

I also decided to attempt my first installation of Oracle Enterprise Manager 12c. I had one other database server with an adequate amount of memory to attempt the installation but so far it’s been slow going (stuck at 66% for quite some time). I’m sure my ‘ignoring’ the 3GB physical RAM requirement will cause an issue since WebLogic loves to crash on low-memory machines (java… meh) At least I tried and suppose I could always shutdown the two RAC nodes to reclaim 4GB of physical RAM to ensure a successful installation.

So, there you have it, my weekend in less than 500 words.

Note: Summary of installation steps to be provided on Samdog Consulting site in the near future.

Update: Oracle Enterprise Manager 12c install did actually die upon first attempt. Successfully installed after server was brought up with 5GB physical RAM. It’s a pig but to be expected I suppose...
