Hi All,
I have a message flow that can run on two brokers on two separate machines. At run time I want to know the name of the queue manager attached to the broker within a compute node. What are the different options to get this?
Thanks

There is basically one and only one option.
A plug-in node.

Even in 5.0 there is no system variable or a some message tree that can capture this?
Thanks

Now that it has been upgraded to v5 and removed from the "withdrawn" list of supportpacs you could look at using the IA06 Get all environment variables Plug-In supportpac.
On each broker server set an environment variable, say WBIMBQMGR, to the queue manager name that supports that particular broker. Within your message flow exercise the Get all environment variables node and subsequently query the new ENV tree (Root.ENV.WBIMBQMGR) in a compute/filter node to determine the queue manager name.
This scenario no longer works for us as our configuration now has each broker server supporting multiple brokers, thus on any given broker server the message flows that span multiple brokers would retrieve the same queue manager value. Since you have the brokers running on separate servers this limitation doesn't apply to you. |

JT -
For your situation, you might look at the LDAP plug-in to augment your flow with an LDAP value selected based on the broker name.
But, for Kirank - as far as I know this has not changed for version 5. But consult your documentation!

I have separate Broker databases for each of the two brokers. Can I get the queue manager name from any of the tables within the broker database?
I don't want to go into implementing Plugin node so trying to explore other options.
Thanks

Well, other option is risky. What happens if IBM changes the table schema with next CSD release? It'll be simple to write a plug-in node to get queue manager name at runtime. It's one function call. Please search in this forum and you will find references to that function.

Or think about your design, and why you actually need (or more likely think you need) the QM name.
Cheers,
