IMS DLI Batch Engine Subtask |
Scroll |
Precisely recommends using either Started Tasks or the z/OS Master Controller for large numbers of IMS DLI Apply Engines.
Example:
Execute an engine subtask, running under IMS (DFSRRC00) as a DLI Batch process within the z/OS Master Controller using the startup parameter file, MASTIMSD, listed below.
MASTIMSD Parmlib member included in the distribution
QMGR=N/A
CMDQUE=SQDATA.CMDQUE
UPSTATE=N
WTOR=Y
WTORMSG=SQDATA TEST ENGINES READY
FAILJOB=Y
FAILMAX=3
----------------------------------------------
-- ENGINE LIST only 1 allowed for DFSRRC00 --
----------------------------------------------
NAME=IMSTOIMS
PGM=DFSRRC00
AUTOSTART=X
NEWADDRSP=N
SCRIPT=DLI,SQDATAI,APPLYPSB,,,,,,,,,IMSA,,Y
QUEUE=IMSTOIMS@SHM
Notes:
1.The program name of the subtask is DFSRRC00, which is the name of the IMS control module. The SQData program required to run under IMS only is SQDATAI.
2.The parm usually passed to IMS must be specified as the SCRIPT= value.
3.AUTOSTART=X instructs the z/OS Master Controller to shutdown if the Apply Engine stops.

Note: The SQDFILE DD is required for execution against IMS and should reference the parsed script library member.
