Hi,
  I have the following scenario:
OS: AIX 6.1
RDBMS: Oracle 11.2.0.3 CPU JUL2012 (no other patches, the PSU failed due to
lack of space)
This is a 2 node RAC.
Separate users for GI (grid) and RDBMS (oracle).

So far this is pretty standard.

The pmon starts correctly:
dbserver01:/u1/app/grid/11.2.0/network/admin>ps -ef |grep pmon
  oracle 26345656        1   0   Oct 13      -  0:57 ora_pmon_<SID>1
    grid 28704882        1   0   Oct 12      -  1:08 asm_pmon_+ASM1

however, the server processes are started with grid:
dbserver01:/u1/app/grid/11.2.0/network/admin>ps -ef |grep oracle<SID>
    *grid  *6291568        1   0   Oct 13      -  0:00 oracle<SID>1
(LOCAL=NO)
  *oracle *22937652 10354818   0 15:59:09      -  0:00 oracle<SID>1
(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))

(note that SID is the same always as there is only one DB in this RAC)

Now. I've never seen this before, maybe I wasn't paying attention or maybe
this is something exclusive to AIX. But I find this odd. Has anyone seen
this before? is this expected behaviour or a wrong config somewhere? Or
maybe a bug?

Thanks

Alan.-
