You use the FMN
Each line in
FMN IMSIN starts with a $$FILEM and the first line contains
the parameter DIB to specify that
FM/IMS will initialize a database.

DIBTYPE
The Initialize step to be run.
INSERT
Specifies a step that inserts a dummy segment into the database.
DELETE
Specifies a step that deletes the dummy segment from the database.
Note: To successfully run the Initialize (DIB) function the specified IMS subsystem must allow the
use of both dynamic PSBs and DL/I batch processing regions.
