4.3.3.2.18 IUDBINIT Operational Job

The IUDBINIT job applies only where you have activated
incremental update for one or more products in the unit
database.  You execute IUDBINIT to re-initialize in-progress
incremental update processing after restoring the unit
database files (i.e., after running the RESTORE job).
Messages in the RESTORE job MICSLOG will prompt you to
execute IUDBINIT when needed.

The JCL for the IUDBINIT job is in prefix.MICS.CNTL, member
IUDBINIT.

The IUDBINIT job loops through the products installed in the
unit database to locate those products for which you
specified INCRUPDATE YES in prefix.MICS.PARMS(cccOPS).

o  IUDBINIT allocates each product's incremental update
   checkpoint file to determine if one or more INCRccc jobs
   executed (or are in progress) since the last DAILY job
   execution.

o  If you specified INCRDB PERM (or took the default) in
   prefix.MICS.PARMS(cccOPS), then IUDBINIT allocates and
   clears the product's IUDETAIL and IUDAYS incremental
   update database files.

o  If you specified INCRDB TAPE or INCRDB PERM in
   prefix.MICS.PARMS(cccOPS), then IUDBINIT deletes the
   in-progress IUDETAIL and IUDAYS incremental update data
   sets.

o  Then IUDBINIT initializes the incremental update
   checkpoint file, preparing it for the next INCRccc or
   DAILY job execution.
