Shared Memory Segments

I solicit your help with this DU/Oracle shared memory problem.

Banner (SCT) suggested that 100meg would be a size to start with for
shared pool size.

When I changed shared pool size to 100meg I got the following error
message:

ora-7329 - too many Shared Memory Segments -

The cause is --

The internal data structure that holds segments infromation is full.

Action is -

Reconfigure the UNIX kernel to have larger segments

I changed it to 80meg and Oracle came up.


Here are my kernel ipc values:
   shm-max = 4194304
   shm-min = 1
   shm-mni = 128
   shm-seg = 32

Environment:
   Digital Unix 3.2d-2

Which is the appropriate kernel variable to change?

How do I determine the correct value for this variable?


Thanks, in advance, for your help.
