On HP and Solaris platforms, you can designate a specified amount of memory as wired memory. Wired memory is shared memory that is locked into physical memory. The kernel cannot page this memory out of physical memory.

Wired memory may improve SAP Sybase IQ performance when other applications are running on the same machine at the same time. Dedicating wired memory to SAP Sybase IQ, however, makes it unavailable to other applications on the machine.
To create a pool of wired memory on these UNIX platforms only, specify the -iqwmem command-line switch, indicating the number of MB of wired memory. (You must be user root to set -iqwmem, except on Solaris.) On 64-bit platforms, the only upper limit on -iqwmem is the physical memory on the machine.
-iqwmem 10000
On Solaris, -iqwmem always provides wired memory.
On HP, -iqwmem provides wired memory if you start the server as root. It provides unwired memory if you are not root when you start the server. This behavior may change in a future version.
Server memory comes out of a pool of memory used by all applications and databases. If you try to run multiple servers or multiple databases on the same machine at the same time, or if you have other applications running, you may need to reduce the amount of memory your server requests.
You can also issue the UNIX command ipcs -mb to see the actual number of segments.
