DFSDLBN0
Module DFSDLBN0 is used for IMS batch initialization. It is invoked by the batch program controller DFSPCC30.
The functions for DFSDLBN0 are as follows: if logging is needed, invoke DFSXLGI0 for log initialization, then invoke the logical logger to open the log. If the DBMONITOR will be active, load the batch monitor DFSMNTB0, then invoke the monitor to open the monitor data set. Invoke DFSRRA00 to preload any modules. Invoke DFSXIOB0 for second pass OSAM/VSAM initialization. If GSAM is present, invoke DFSZDI00 for GSAM initialization.
Hints
DFSDLBN0 is invoked only once as part of batch initialization and its CPU use should be very low. If the batch job just initializes, issues only a few calls, and then ends, the proportion of CPU used for initialization will be higher.
