Database Processes Owned by group admdba, not oinstall
I have a newly installed 11gR2 RAC system with ASM running on Linux. It has role separation setup. So the clusterware and ASM are owned by user "grid" and database is owned by user "oracle". Both oracle and grid user has default group set to oinstall. User oracle is also a member of group "dba" and "asmdba". User grid is a member of group "asmdba", "asmoper", and "asmadmin".
Now I found my database background processes, like pmon and smon, are owned by oracle:asmdba, instead oracle:oinstall as I believe it should be. I don't know why this happens (I did not do the install) and how to fix it. Anyone has an idea?
Thanks.
