Options that you must code exactly as given
In some cases, DB2® requires particular values of APPL options.
For the following options, you must code the values exactly as shown; they are not the VTAM® defaults:
- APPC=YES
- Tells VTAM that DB2 uses APPC conversation verbs.
- AUTH=(ACQ)
- Determines the DB2 system authority to use certain VTAM functions.
- SRBEXIT=YES
- Tells VTAM that DB2 uses service request block (SRB) processing in its exit routines.
- SYNCLVL=SYNCPT
- Tells VTAM that DB2 supports two-phase commit. Other
systems communicating with this DB2 use
this indication to determine if DB2 supports
the updating of many locations in one unit of work.
Coding SYNCLVL=SYNCPT does not preclude the support of partner LUs that do not support two-phase commit. DB2 still supports the non-two-phase process.
