This is a Digital Unix 4.0B/Oracle 7.* question. Our DBA asked me to
set the following system parameters:
shmmax - max. shared memory segment size - DBA says "set this to 80% of
the max. amount of memory we can use", indicating it should be 80% of total
physical memory - oracle info indicates the unit here is in bytes
- ? is the unit of shmmax in bytes ?
shmmni - number of shared memory identifiers - DBA says "set this to the
maximum number of shared memory segments in the system"
- ? how does one find/define the maximum number of shared memory segs ?
shmseg - number mem. segments a user process can attach - DBA says "set this
to
maximum number of shared memory segments a user process can attach"
- ? how does one find/define the maximum number of segs a user can att.?
shmmns - ? This one appears to be an Intel param, not a DEC param - true?
Many TIA!!
