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.- -- //www.freelists.org/webpage/oracle-l
