In Response To: SHMBASE (Mike Badar )

Thank you Bogdan. I checked the online.log and the resident + virtual
segments were greater than my SHMTOTAL. I modified my resident segments
(BUFFERS, LRUS, LOGBUFF, PHYSBUFF, LOCKS) and the engine is now up and
running. Thanks again.

Mike

Greetings,

AFAIK, the meaning of these three parameters is:

SHMVIRTSIZE - the initial memory segment size (shared memory) in KBytes
SHMADD - the size of the next allocated segments in KBytes
SHMTOTAL - the total amount of shared memory to be used by the instance in
KBytes

I'm pretty sure that as soon the instance will require more than 512MBytes
will attempt to allocate other memory segments, each having 32KBytes with
the net result of exceeding the number of allowable segments/memory.

Please increase the SHMADD value and post the exact errors from online.log.

Regards,
Bogdan BOTEZ.
