CICS-supplied groups within CICS system definition
Program, transaction, and mapset entries for the CICS® system definition file (CSD) to provide DBCTL support are supplied in the group DFHDBCTL.
This includes the DBCTL connection and disconnection transaction, CDBC, the inquiry transaction, CDBI, and the operator transaction, CDBM. DFHDBCTL is in DFHLIST, which contains the CICS resource definitions needed to run IBM® supplied transactions that must be installed in your system. Also in DFHLIST is the DFHEDP group, which provides the program definition required to run EXEC DLI applications. The group DFHEDP must always be installed in the CICS system. If you need further information about DFHLIST, see Supplied resource definitions, groups, and lists.
- RESTART
This option defines whether CICS will attempt to restart a transaction that has been backed out after a failure. (See Deadlocks and interactions with automatic restart.)
- SPURGE
Specify SPURGE(YES) so that the transaction can be purged using CEMT. Purging a transaction that is using DBCTL tells you how to use CEMT in this way.
