shared memory segment/value?

Tina Waitherwerch — Tue, 04 Jun 2002 18:52:51 GMT

To which parameter is this referring: shmmax,shmmni, or shmseg or ....?
"The default total logical memory parameter for HP is 45,056 2K pages (88MB) on the 64-bit operating system. To adjust the shared memory value of the operating system, use the System Administration Manager (SAM)."

You need to change shmmax according to your requirement.

It appears to be referring to shmmax but the statement is incorrect. It is specified in bytes and the default is 64MB. (0x4000000). The maximum values are 1GB (32-bit) and 4TB
(64-bit) with a minumum of 2K.

It is just possible that this a a vague reference to maxswapchunks which also can set an upper limit on the amount of shared memory available.
