Hi...

We are preparing to upgrade from 10.2.0.5 to 11.2.0.2 on IBM AIX 5.3 TL12. With the upgrade we want to implement job/role separation.

We currently use ASM which is installed in it's own oracle home under the 'oracle' user. Our plan is to use 'grid' for the userid, 'asmdba' as the dba group for the GI software, and select 'Upgrade Grid Infrastructure' for the installation option however the disks used by the existing ASM instance are owned by oracle/dba.  Will I have to create a new ASM instance (with disk owned by grid/asmdba) or can I simply change the disk owner/group on the server to grid/asmdba for all disks (currently) used by ASM? If so, will there be any impact to ASM/databases?  I understand the DB owner (oracle) must be a member of the asmdba group.  Do

Howdy, Stranger!
