By default, assets deployed with a WebSphere MQ configuration will copy the MQMD characterSet, messageId, and correlationId from the incoming request MQ Message to the outgoing response MQ message. This is the default correlation mechanism.

If a different correlation mechanism is required, such as making the virtual asset copy the incoming request messageId into the outgoing response correlationId, then you can configure this at the Message Responder level. To do this:

1. Chain a Header Data Bank tool to the incoming header request of that responder and extract the messageId (or the desired MQMD field) value (see Header Data Bank).
2. In the Message Responder Transport Header Options, MQ (see Transport Header Tab) add messageId (or the desired MQMD field name) and parameterize its value with the request messageId or field provided by the Data Bank. This approach can be used for MQMD MQMessage fields as desired.
   • For the list of MQ Message MQMD field names recognized and handled by Virtualize, see the MQMD documentation.

Note that Virtualize will display a hex-encoded representation of the byte array fields in order to allow their values to be readable in the data bank and traffic views. However, the exact byte content will be transferred gracefully from the request to the response messages—preserving messages, preserving the original byte contents.
