Job control statements to run the DFHLSCU program

DFHLSCU runs as a standard operating system job. You must define a JOB statement, and EXEC statement, and a JOURNAL statement. The job stream to run the DFHLSCU utility should include the following DD statements:

STEPLIB DD
defines a partitioned data set (DSORG=PO) containing the DFHLSCU module. If the module is in a library in the link list, this statement is not required.
JOURNAL DD
defines the CICS/ESA 4.1, or CICS/ESA 3.3, journal data set that is to be examined by the utility. Multiple journal data sets can be specified by concatenating additional data sets to the DD statement, they should originate from the same CICS® system (that is, they should not be a mixture from different regions).

See the CICS/ESA 4.1 Operations Guide for information about journal data set definitions in JCL and Considerations when using DFHLSCU.

SYSPRINT DD
defines the output data set that will contain the formatted print records and control messages. This is usually defined as SYSOUT=A.

The DCB parameters specified for this data set are RECFM=FBA and LRECL=133. The block size may be provided on the SYSPRINT DD statement and must be a multiple of 133. The default is 133.

SYSIN DD
defines values and parameters to be used by the utility. This file must be in 80-byte record format. One SYSIN statement per line is permitted. Ensure that your statements do not exceed column 71.

Using SYSIN statements, you can pass values to the utility to be used in the report calculations and recommendations. These assume default values if you do not specify them explicitly. The utility is invoked as follows:
