When the CICS® Service Flow Runtime encounters
an error, the error records are written to the defined transient data queue
(TDQ).
An error listener program retrieves the error records off the queue and
writes them to an Error file. The Error Listener program name is DFHMAERQ;
the transaction ID is CMAQ. You can also use WebSphere MQ to perform error
processing. See
Error processing using WebSphere MQ for
details. Both options are shown in the figure below.
