How many Semaphores needed?
For Oracle Enterprise Server 188.8.131.52
We are working on getting a new HP-UX 11i (64-bit) server and need to know the semaphore requirements for the unix group.
As per Oracle's recommendation for each instance -
Semaphores = ((value of processes in init file)*2) + a few for Oracle's internal use.
My questions are -
# is the equation same for 64-bit OS (and database)?
Is this a good estimate depending upon if I estimated my processes correctly for all the instances?
# Does this number change with Oracle 9i?
