MQ Series Trigger

[raviyn]

Hi,

After going through the Documentation i have understood that for DS to work with MQ we need to have on DS Server an MQ Series Server which can later connect to any other remote MQ Series server .

What I wanted to know was :

1) How can we trigger a DataStage job as soon as a we have a particular message on the remote queue ? Does DataStage automatically trigger the Job if I am using a Job containig the MQ Series Adapter Read Stage or is there any other way of doing it ?

2) Also I want to process these records and then put in back into the same MQ Server Queue ? So will it cause any issues and also is there anything special that i need to consider in case of job failures ?

Any

Thanks in advance

Unless you create an "always running" DataStage job (or job sequence) that listens for the particular message you do not have any mechanism within DataStage to do what you request.

You could create your own listener external to DataStage and have that trigger a DataStage job via the command line interface dsjob but you would need to be very wary that execution completed before another attempt was made to trigger the job.

Thank Ray.

I thought MQ series was all abt real-time and all so thought we have some Event based triggering in Datastage based upon the message being there or not in the queue something like an Event based trigger for a file in a particular folder

The story gets better in version 8, but that's not here yet.
