Installed 2 node, 2 instance RAC on my laptop

Finally installed 2 node, 2 instance RAC on my laptop after quite a number of trials. Followed Tim Hall's document to configure it.

I was having problems when I was installing the clusterware. At the end of installation, the clvfy utility checks for cluster integrity and it fails every time. Tried a couple of things to repair it, but it never worked. Finally I tried to sychronize the time of each virutal machine with the host OS and it worked. It always throws up an error like below , if the nodes are not synchronized.

"/bin/tar: ./inventory/Components21/oracle.ordim.server/10.2.0.1.0: time
stamp  2006-11-04 06:24:04 is 25 s in the future"

The article below explains how to synhronize the guest OS time with host OS.

Tired it out and it worked.

Now i've a single node-2 instance and 2 node-2 instance RAC installed on my laptop.

Trying to explore more of it now. (Understanding cache fusion, Transparent Application Failover (TAF) etc...

Installed RAC on my new Laptop

Recently bought a 2GB RAM/160GB Hard Disk laptop ('cos i failed miserably trying to install RAC on my 512MB RAM laptop) and tried to install RAC on my new machine.

I've followed dizwell's document and installed RAC on my laptop. It was pretty smooth. No issues at all. Here's the link to follow.

what a pretty good documentation. Amazing. Since RAC is new (may be not)... i mean fairly new, and it needs a lot of linux, network settings that are quite complicated. Dizwell has done a very good job in explaining them in a step by step procedure. kudos to dizwell. This is a single node two instance RAC.

Tim Hall is also gave another excellent documentation. He wrote an article to create a two node RAC as opposed to single node RAC documented by dizwell.

Here's the link to follow.

I've tried that too, but as of now i'm stuck with the ASM instance not mounting on the second node. It gives me an error saying "network or resource busy" for the ASM mounted file system when it tries to mount on the second node. Need to figure it out. Will post here once i figure it out.
