Hi All,
I am using WBIMB ver 5. Is there any option in the Publish message that I need to set for saving the Correlation Id instead of Broker generating a new one.
Also, The correlation Id generated will be different each time its published.
If yes, can someone let me know how it can be done.
Thanks in advance
Ved

It's not possible to do this, I think.
Also, you shouldn't need to do this.
What problem are you trying to solve with this idea?

Ok got it.
DECLARE CORRID CHAR '123XYZ';
DECLARE ASCII_CCSID INTEGER 437;
DECLARE BIN_CORRID BLOB CAST(CORRID as BLOB CCSID ASCII_CCSID);
DECLARE TEMPLATE BLOB X'000000000000000000000000000000000000000000000000';
DECLARE NEW_CORRID BLOB BIN_CORRID || TEMPLATE;
SET NEW_CORRID = SUBSTRING (NEW_CORRID FROM 0 FOR 25);
SET OutputRoot.MQMD.CorrelId = NEW_CORRID;

Um.
Set OutputRoot.MQMD.CorrelID = CAST(SUBSTRING('123XYZ'||X'000000000000000000000000000000000000000000000000' from 0 for 25) as BLOB CCSID InputRoot.Properties.CodedCharSetID);
But there's no guarantee that the broker will maintain this when it publishes.

I am setting it after the broker publishes and re-deliver it to the original subscriber. I am working on this pub sub proxy here that allows .NET, Cobol or any other API's/programming languages use broker pub/sub via XML and P2P comms.

MQMD for publications forwarded by a broker
If CorrelId is part of the subscriber’s identity, this is the value specified by the
subscriber when registering. Otherwise, it is a non-zero value chosen by the
broker. |

Kspranava is saying that, if the subscriber requested that the message have a particular Correl-ID in the subscription request, that the broker will set that Correl_ID on all publications to that subscriber. If the subscriber does NOT request the correl_id, then the broker will always set a new correl-id.
