Hi,

We are calling a stored proc(DB2 9.x) from WMB 6.1. But we have a requirement to put timeout notification for this Stored Proc.

Eg: If a stored proc does not return any results bu 60 secs we need to send out timeout reply back to the sender

Is there a way we can control this in WMB?
How will the design pattern look like?

Thanks
Prasanna

Dunno how you can time out your stored procedure call (but I guess it might be a facility of the database) but to send a timeout back to the requestor you can do something like this:
1. Requestor makes request by putting message to MQ queue
2. He then does a MQGET with wait of 60 seconds on a reply queue
3. A broker flow reads the request queue and calls the stored procedure
4. If no response comes back from the stored procedure in 60 secs the MQGET with wait will time out.
