CPI-C application program recovery

No recovery processing exists for application programs using the explicit CPI Communications driven interface.

IMS discards all CPI Communications driven transactions at restart regardless of their state at the time of failure. Application program designers should be aware of the SAA resource recovery resynchronization functions and consider the impact on their application program designs.

The application program should provide full integrity by issuing a SAA resource recovery Commit or Backout call for session failures. Application programs that require recovery assistance must be standard DL/I application programs.
