Purpose
Changes the mode of communication between TDP and an application program.
Syntax
where:
- SVC
- Specification that the communication mode be a supervisor call (SVC).
- nnn
- Number of the SVC to be used.
- DYNAMIC
- Indication that the SVC is to be installed into z/OS by TDP when started, and removed by TDP upon stopping.
- PC
- Specification that the communication mode be a program call (PC).
Usage Notes
The DYNAMIC option must not be specified if multiple TDPs are to use the same SVC number. If DYNAMIC is specified, the first TDP to be stopped removes the SVC from the system, making it unavailable for the other TDPs.
When the database uses more than one version of the TRDTMAS (z/OS) or TRDTHAS (VOS3), each version is identified by a unique SVC number, nnn.
