Transaction Failure program

The abnormal condition program has been divided into two new programs according to function.

  1. DFHTFP which is a new program that is invoked after transaction initialization on abnormal termination.
  2. DFHACP which is invoked by transaction manager whenever an incorrect transaction is detected.

The transaction failure program (DFHTFP) is invoked during transaction abend processing. Its purpose is to reset the status of a terminal attached to the transaction, and to send a message informing the terminal operator that the transaction has abended. It also calls the user-written (or default) program error program (DFHPEP), and writes a message to the CSMT transient data destination.

DFHTFP resolves any abnormal conditions other than those associated with a terminal, or those handled directly by the operating system.
