Anurag, We have several RAC/CRS installations as oracle, which works fine. Check www.oracleracsig.org for documents/notes.

I will be using a non-root user as the Oracle Clusterware owner. Have any of you installed Oracle 10g RAC with a non-root user as the Oracle Clusterware owner? If yes, do you have any documents or links or Metalink notes as reference? Thanks for your help, -- Anurag Verma, Database Administrator ERCOT(Electric Reliability Council of Texas), Texas 76574
