HI

Is there any possibility that MQ Series do some internal updates on SYSTEM.CHANNEL.INITQ - which can leed to change ALTDATE / ALTTIME ??
I know that XMITQ are modified and MQ Series "engin" changes ALTDATE / ALTTIME due some internal procedures.

please
advice

Transmission queues may be get inhibited due to channel failures. This will affect the altdate attribute value. A common method of auto-starting channels is by triggering the transmission queue. One of your xmit queue definitions specifies the SYSTEM.CHANNEL.INITQ as the initiation queue to be used by the channel initiator program (runmqchi on midrange, CHIN in z/OS). Channel failures may cause mq to inhibit the initiation queue.

If you are on z/OS check to see if there are any DEFINEs for the system objects in the startup JCL (CSQINP1 & 2). Sometimes people use this to ensure that the SYSTEM* objects are always going to be there to ensure that the queue manager will come up regardless of if someone deleted a key object.

I am not sure if this is the case on the penguin platforms or on the i Series boxes but it may be what is happening.
