//*
//*  Before running this job, you must change the following:
//*
//*    1. Change the name in the DSN SYSTEM(DB2) statement to
//*       the name of the DB2 Subsystem in your installation.
//*
//*    2. Change the PLAN name (DSNTIA71) in the RUN statement to
//*       match your current DB2 version and release level.
//*
//*    3. Change the data set name in the RUN statement
//*       LIB('DB2MINI.V7R1M0.RUNLIB.LOAD') phrase to the data set name
//*       used in your installation for the DB2 RUNLIB.LOAD data set.
