Jim is correct, most probably the size of the SGA is wrong for the amount of memory the system has.
Furthermore, depending on the OS version, you might look at the vmo parameters. Issue a
and check "minperm", "maxperm" and "maxclient". The "revolutions of the clock hand" (see vmstat -vs) being 0 suggest that even though a lot of paging goes on there is no real shortage on memory. The value counts how often the lrud (last recently used-daemon) has gone throught the complete memory to find pages it needs for applications.

The command is "ipcs", like everywhere else. "ipcs -m" will show the shared-memory-segments.
Hello,
I need explanations about physical disks and physical volumes. What is the difference between these 2 things?
In fact, i am trying to understand what the AIX lspv2command does.
Thank you in advance. (2 Replies)

2)Volume Group
3)Logical Volume
4)Physical Partition
Please help me to understand these concepts. (6 Replies)

ipcs
IPCS(1) User Commands IPCS(1)NAME
ipcs - show information on IPC facilities
SYNOPSIS
ipcs [options]
DESCRIPTION
ipcs shows information on the inter-process communication facilities for which the calling process has read access. By default it shows
information about all three resources: shared memory segments, message queues, and semaphore arrays.
OPTIONS -i, --id id
Show full details on just the one resource element identified by id. This option needs to be combined with one of the three
resource options: -m, -q or -s.
-h, --help
Display help text and exit.
-V, --version
Display version information and exit.
Resource options
-m, --shmems
Write information about active shared memory segments.
-q, --queues
Write information about active message queues.
-s, --semaphores
Write information about active semaphore sets.
-a, --all
Write information about all three resources (default).
Output formats
Of these options only one takes effect: the last one specified.
-c, --creator
Show creator and owner.
-l, --limits
Show resource limits.
-p, --pid
Show PIDs of creator and last operator.
-t, --time
Write time information. The time of the last control operation that changed the access permissions for all facilities, the time of
the last msgsnd(2) and msgrcv(2) operations on message queues, the time of the last shmat(2) and shmdt(2) operations on shared mem-
ory, and the time of the last semop(2) operation on semaphores.
-u, --summary
Show status summary.
Representation
These affect only the -l (--limits) option.
-b, --bytes
Print sizes in bytes.
--human
Print sizes in human-readable format.
SEE ALSO ipcmk(1), ipcrm(1), msgrcv(2), msgsnd(2), semget(2), semop(2), shmat(2), shmdt(2), shmget(2)CONFORMING TO
The Linux ipcs utility is not fully compatible to the POSIX ipcs utility. The Linux version does not support the POSIX -a, -b and -o
options, but does support the -l and -u options not defined by POSIX. A portable application shall not use the -a, -b, -o, -l, and -u
options.
