Hi Suchit,

The permissions for root and oracle on each node so that they can do rsh commands on the other node. Each account needs to be set up the same way on both nodes and there needs to be an .rhosts on the other node so that oracle on ops1 can do 'rsh ops2 ls' without running into permission problems.

The oracle installer depends on the above to do the OPS installation since it is run on one node and copied to the other. Additionally, when you have the Cluster running and all the permissions set correctly then the Oracle installer will sense the other node and ask you OPS related questions - such as: install on ops1 and ops2.

Regarding the docs: yes the SC 3.0 docs. They should help you in detail to get the disk partitioning, networking and user accounts. Then you go to the special OPS section (Unfortunately, the 2.2 docs left out the DLM stuff and referred to the Oracle docs, which as far as I could locate didn't either). Eventually a friendly Sun FE pointed out that I would need to install DLM (from the Oracle CD) to even get the Cluster running. Once it was running I discovered that I didn't have the VxVM Cluster option license after spending many days/nights reading the Veritas/Oracle docs. After you get the "cluster option", the shared raw volumes can be created. You then need to "start" them from the GUI and then oracle can be installed.

From the other response you got, it sounds like the Global File Service isn't one that you can use. I'm fairly certain that leaves you with SDS from Sun or VxVM from Veritas.
