IBM zS: 11gR2 PARALLELISM ON AIX 6.1 : OS requirements ?

edited Jan 11, 2014 11:23PM in Rdb on OpenVMS, IBM zSeries and Oracle on OpenVMS (MOSC) 1 commentAnswered
Hi ,

I implemented Oracle parallelism at instance level by using PARALLEL_DEGREE_POLICY=AUTO (11g feature).

In my application , only few queries have been automatically parallelized (PX servers appear in execution plans).

but no change in  execution time (like execution time in serialized execution).

I checked CPU and RAM and all parallel oracle parameters : OK

How can I check that no limitations exist at OS (AIX 6.1)  level to implement oracle parallelism ? OS capped ?

More informations :

Processor Clock Speed: 3504 MHz
CPU Type: 64-bit
Kernel Type: 64-bit
LPAR Info: 8

Memory Size: 28672 MB
Good Memory Size: 28672 MB
Platform Firmware level: EM340_132
Firmware Version: IBM,EM340_132

Howdy, Stranger!
