DDM commit and rollback processing

The IMS implementation of the distributed data management (DDM) architecture includes support for commit and rollback processing.

XA support and the processing of global transactions is controlled by the DDM commands SYNCCTL and SYNCCRD.

The processing of local transactions is controlled by the DDM commands RDBCMM and RDBRLLBCK.

IMS does not extend these DDM commands beyond their original specification by DRDA.

Documentation for these commands can be found in DRDA, Version 4, Volume 3: Distributed Data Management (DDM) Architecture.
