Hello,

One of the MQ projects I am working on uses MQ series along with Webmethods MQ Adapter. Placing xml files a segmented messages is a quick and easy process and the perfomance of the MQPUT calls are quite good. I have a perfomance issue on the other hand with the MQGETS.

The adapter requires a listener service with pulls off the first message and stores the correlation id and then issues a GET serivce to pull off all the other messages which match the correaltion id. This works fine if the queue depth is faily low.

BUT
If there are around 700+ messages on the queue, the MQGET API call performance is hit drastically. The Get service on the MQ adapter is procedure which interogates the queue for a matching correlation id. Is there anyway this can be made into a more streamline process.

Cheers

Try indexing the queue. I am not sure if this is just an OS/390 option.

Thanks but I think it is only a OS/390 call. We are running on NT.

Do you know if NT MQGET call supports any form of indexing or does it just rely on the selection criteria of the msgid and correlid?
