Dear unix gurus

I am installing oracle8i on a two node tru64 unix cluster sharing a common disk file system. My question is:

1) do I just create the Oracle account on only one of the nodes in the cluster, and

2) Since both nodes on the cluster share the same disk filesystem, will the installation of the oracle binaries be done once from any of the cluster members?

Thanks a lot.

Any other useful tips will be most appreciated.
