I have my MQSI flow building a xml request and putting to a request queue, Another host applicatoin does a get, processes and puts in a reply q in max 60 seconds (if not time out). The MQSI flow then continues on..

Is there a node or technique or java plugin to do this?

I noticed the Aggregator node does have a timeout but my reply is from a single queue ..

thanks.

There is no readymade node available, which implements delay/wait-time functionality. However, you could try modifying MQGet plug-in source to implement MQGMO_WAIT functionality.

Introducing GMO_WAIT is not a good idea.
Remember you will be blocking the input queue and hence
scaling and multi-threading will become a problem.

WMQI is designed to be stateless and non-blocking.

There are some excellent discussions in the forum.

I agree with what you are saying. Developing a custom plug-in node to introduce "delay" will cause the same problem.

vmurdesh,
Try to put waiting logic outside of WMQI. Above thread urls will give you some good ideas on how to implement this. If you are not able to find solution then please post your requirement in more detail.
