Recovering from APPC problems

Advanced Program-to-Program Communications (APPC) attempts to restart automatically when it encounters an unrecoverable error. APPC contains two address spaces, APPC and the APPC/MVS transaction scheduler (ASCH). Both address spaces attempt to restart independently of each other so that, if the APPC/MVS transaction scheduler abnormally ends, APPC can continue normal processing.

For both address spaces you must perform recovery actions for the following:
  • Initialization problems
  • Abnormal ending with restart
  • Abnormal ending without restart
