Build your own RAC system part V – add RDBMS home

Posted by Martin Bach on February 15, 2010

This article concludes my short series about how to build your own RAC system-I might explore an extended distance cluster with 11.2 soon so stay tuned for more material. As you could read in my previous posts, I have installed a cluster on 2 (now 3) nodes, with a fresh 11.2 Grid Infrastructure installation. I then wanted to extend my RDBMS home to the 3 node.

As I use to say-it’s easy to extend RAC once the cluster layer is in place and working. In my case, that was a given so I continued with the extension.

I knew from extending the Grid Infrastructure that addNode.sh was headless and silent-you need to pass appropriate parameters and it will do it all for you. In my case I logged in as oracle to the first node and changed directory to $ORACLE_HOME/oui/bin. There I tried the following, and it worked without problems! My cluster is made up of rac11gr2node{1,2,3}, the RDBMS software was already present on nodes 1 and 2. I should actually have run a cluvfy but was too lazy (I wouldn’t do this on any non-lab environment!)

[oracle@rac11gr2node1 bin]$ ./addNode.sh -silent "CLUSTER_NEW_NODES={rac11gr2node3}"

Cool – it seems like it was never as easy as  this! I checked if it worked by invoking opatch on the newly added node in $ORACLE_HOME/OPatch/:

[oracle@rac11gr2node3 OPatch]$ ./opatch lsinv

OPatch succeeded.

Success! Note that it’s intentional to use opatch 11.1.0.6 with 11.2 for now…

On a future post I’ll try to work out how this affects server pool and policy managed databases.
