DataStage PX and MQ Client

bcarlson · Post by **bcarlson** » Thu Apr 24, 2008 1:39 pm

We are just starting to experiment with using DataStage and MQ and ran across this in the documentation:

For instructions and information supporting the installation, see
WebSphere DataStage Plug-In Installation and Configuration Guide.
Note The MQ Series Client-only option is unsupported.

Does this mean we can only use DataStage with MQ if the DataStage server is on the same platform as the MQ server?

Yes. For version 7.x, MQ client, MQ server, and DS server all reside on the same box.

Is this unique to 7.x and is resolved in v8 or does v8 have the same issue?

It is resolved in version 8. You must have MQ client (obviously), but the MQ server no longer needs to be co-located with the DataStage server.

So if DataStage is installed on the same server as MQ server, can it connect to queues on another server? Or can DataStage only connect to local queues?

It can connect to queues on other servers. The local queue manager uses MQ intercommunication to communicate with the remote queue manager(s).

And is this intercommunication something that must be configured in DataStage, MQ or both? What exactly is the nature of this MQ intercommunication? Does it involve server to server message passing? (remote server passes messages to queue on local queue manager).

All DataStage wants to know about are the MQ queue manager and teh MQ queue name. If those can be accessed from the DataStage server command line using the mq commands (i.e. "dspmqaut") then you are good to go from DataStage.

Is anyone here currently using Hawk with MQ Series? If so, how do you access a queue using only the MQ Client, (with no server installed.) Is this even possible?

The version 8 MQ stages allow you to specify a local or remote queue manager.

MQ Intercommunication is configured within MQ Series, from one queue manager to another.

We are using MQ with HAWK both with real-time components, the Oracle UOW operator and a customer MQ UOW operator at this installation. Although we do have local queues, the work is done on queues local to the mainframe.
To repeat a question from earlier - can you execute the command "dspmq" to display known queues from your DataStage server?

Hey cool! Yeah I can see this! Thanks!
