Message Queue exceeded.

[zsujith]

Hello,

Want to know what commands are there in HPUX to find out "message queue exceeded" issue.

Regards

Have you looked at any of these kernel parms?
msgmax(5) - maximum System V IPC message size in bytes (OBSOLETE)
msgmbs(5) - maximum number of megabytes for all System V IPC message queues
msgmnb(5) - maximum number of bytes on a single System V IPC message queue
msgmni(5) - maximum number of system-wide System V IPC message queues (IDs) allowed
msgseg(5) - number of System V IPC message segments in the system (OBSOLETE)
msgssz(5) - number of bytes in a System V IPC message segment (OBSOLETE)
msgtql(5) - maximum number of System V IPC messages in the system at any time

>From which command to verify.

For 11.23 and on: kctune msgmni
For 11.11, you'll need to use kmtune.

Hello,

For example i get the output using ipcs -m -b. But what that output indicates.

That gives shared memory segments. You want "ipcs -qa" for message queues. ipcs(1) will describe the columns.

Hello,

Message queues exceeded means we have to take a count of ipcs -qa|wc -l ....Am i right?

Except for titles, it seems like it.

On 11.23 you can just use:
kcusage msgmni
