Hi,
How can see the size of the Queue that has enough capacity store the message.
we hv problem that high length message is disappearing while putting into queue where as small length message is putting messages.
What could be the reason? Is there any way i could find the capacity is enough to fit the high lenth message.

No. That's the default maximum message length.
The actual maximum message length is 100MB. This needs to be set on the queue manager, the queue in question, and any channels (and other queue managers) that need to use messages of that size. It's easier to set this when the queue manager is created. |

Okay, again, you need to set MAXMSGL on both the Queue Manager itself AND the queue.
Running on Solaris, you may also have to adjust your kernel parameters to allow for the MQSeries system to access enough memory to hold 75MBs.
But I don't know how to do that. I'd suggest checking your System Administration guide. |

You will have to change MAXMSGL of queue manager and the queues of interest. The command takes the max message length param in bytes.
Here are MQSC commands to change the max message length to 75MB which by default on Solaris is 4194303 (4MB). The MAXMSGL cannot exceed 100MB.
For queue manager
RUNMQSC myQMgr
ALTER QMGR MAXMSGL(78643199)
Assuming the q is local
ALTER QLOCAL(myQ) MAXMSGL(78643199).
Making sure that value of MAXMSGL for the qmanager is not less than the value of MAXMSGL any of its queues is suggested.
Hope this helps |

How can you change the default value (which is 4 MB) for the message length of the queuemanager?
I know it can be done by using the runmqsc command, but is there another option, e.g.: crtmqm -???
Thanks for any reply! |

You can only alter this property after the QM is created. It is not a parameter for CRTMQM.
