The DFHRST TYPE=SUBSYS macro contains information about a specific DBCTL
subsystem within an RSE. For each subsystem in an RSE there must be a DFHRST
TYPE=SUBSYS macro.

'-,JOBNAME=(jobname1,jobname2,...)-'
- TYPE=SUBSYS
- Defines one of the DBCTL subsystems in an RSE.
- SUBSYSID=subsystem-identifier
- Code
this with the 4-character name of the DBCTL subsystem-identifier. This identifier
must be unique within the RST.
- JOBNAME=(jobname1,jobname2,....)
- Code
this with the MVS™ JOBNAME(S) associated with the DBCTL subsystem
identified in the SUBSYSID parameter statement. This is a form of security
check. If CICS® needs
to cancel the DBCTL subsystem, it is authorized to do so only if the appropriate
MVS jobname associated with the DBCTL subsystem is one of those specified
by the JOBNAME parameter.
