Kernel Configuration

Bobcat_1 — Wed, 28 May 2003 08:54:45 GMT

Hello,
My customer,are in the process of installing an application onto Tru64 Unix V5.1B and requesting for modifying kernel parameters on ipc subsystem.
The settings which is required are as follows -

msg-map=400
msg-ssz=8
msg-seg=32767

Have checked using 'sysconfig -Q ipc' and also from the running kernel (using dbx ), but the above attributes does not appear in the ipc subsystem. Are these attributes still valid ? or is there something that I'm missing ?

Also, the application vendor has pointed us to this url for clarification ,

Thanks.

These parameters are not Tru64 5.1B related.
The following applies to all Tru64 Unix versions:

**MSGSSZ - size of a message segment in bytes

This parameter is part of the IPC tunning parameters. In Tru64 Unix, this parameter is msg-max

***MSGSEG - number of message segments in the system

This parameter has no equivalent, this number grows dynamically in Tru64 Unix.

forgot msg-map:

msg-map is not implemented, a function of (msg_tql + 2)

sorry but it seems your vendor told you the parameters for the wrong operating system.

does my answer give you a clue what must be changed on a Tru64 system?
