Format of OTMA X'6701' log records

OTMA uses the X'6701' log record to document the sending and receiving of certain types of messages, such as messages associated with the processing of synchronous callout requests.

In shared queues environments, OTMA and APPC also use X'6701 log records to document the receipt of certain messages in a front-end IMS system that are sent from a back-end IMS system via a z/OS® cross-system coupling facility (XCF).
