RE: PeopleSoft DBA Forum Kernel Parameters
- As far as Tuxedo is concerned, the only kernel parameters you need to worry about changing are those relating to the message queuesTuxedo only uses 3 shared memory segment per domain, of which the Bulletin Board accounts for most of the size. You simply need sufficent room for the BBs in all domains. I've never had to increase those parameters.You need to ensure that you have the ability to create sufficient message queues and also thatMSGMNI (number of message queues) * MSGMNB (message queue size) >= MSGSEG (number of message segments) * MSGSSZ (message segment size)

Subject: PeopleSoft DBA Forum Kernel Parameters
As per your suggestion, MSGMAX should be the max message size
preferably it should be 256KB and max queue size that is MSGMNB should
be the two times of the message size...can you also suggest the way to
calculate the other parameters value such as MSGSEG,
MSGTQL,SEMMAP, SEMMNI,SEMMNU, SEMUME,SEMMSL, SHMMIN,SHMMNI, SHMSEG.
Formula for calculating the SEMMNI is SEMMNS=SEMMNI* SEMMSL, its also
been suggested to check using boot -c command on tmadmin but for
SEMMNI it is showing A+1 which is bit confusing..
