Our Oracle DBA is requesting some shared memory
setting that I can not find documented anywhere. So
this may be an easy question, but I swear I have tried
to figure this out.
Here is the request.
The very latest info on 9IAS version 2, says the
kernel parameters should be (their were others but I
was able to increase their values)
SEMMAP = 64
c2audit:audit_load = 1
abort_enable = 0
For SEMMAP = 64, I add the following line to
/etc/system
set semsys:seminfo_semmap=64
Question Number 1 ==> When I issue a sysdef -i command
I can't see the change I made? Sysdef below (last few
lines)
* Streams Tunables
*
9 maximum number of pushes allowed (NSTRPUSH)
65536 maximum stream message size (STRMSGSZ)
1024 max size of ctl part of message (STRCTLSZ)
*
* IPC Messages module is not loaded
*
*
* IPC Semaphores
*
4096 semaphore identifiers (SEMMNI)
4096 semaphores in system (SEMMNS)
4096 undo structures in system (SEMMNU)
4096 max semaphores per id (SEMMSL)
4096 max operations per semop call (SEMOPM)
64 max undo entries per process (SEMUME)
32767 semaphore maximum value (SEMVMX)
16384 adjust on exit max value (SEMAEM)
*
* IPC Shared Memory
*
4294967295 max shared memory segment size
(SHMMAX)
1 min shared memory segment size (SHMMIN)
512 shared memory identifiers (SHMMNI)
128 max attached shm segments per process (SHMSEG)
*
* Time Sharing Scheduler Tunables
*
60 maximum time sharing user priority (TSMAXUPRI)
SYS system class name (SYS_NAME)
Question Number 2 ==> I can not find any information
about the last two setting. I have seen reference to
them in the /etc/system file, but I don't like adding
them in the /etc/system file without knowing what it
does?
Any help or guidance will be appreciated.
