FDRABRM JCL Requirements

The following Job Control Statements are required to execute the ABR VTOC maintenance utility:

EXEC statement

Must specify the name of the ABR VTOC Maintenance Utility program, FDRABRM. The REGION=, if specified, must be at least 512K; however, FDRABRM uses only the storage it needs, so REGION=0M is recommended. The first or only control statement may be specified as PARM= data.

STEPLIB or JOBLIB DD statement

If required, must specify the load module library in which ABR resides. This library must be APF authorized.

ABRMAP DD statement

Specifies the destination for the VTOC/DSCB map data set, produced if the LIST= operand is specified. This is an optional DD statement and usually is a SYSOUT data set. If not present, the VTOC/DSCB map is routed to SYSPRINT.

SYSIN DD statement

Specifies the control statement data set, usually an input stream or DD * data set. It can be omitted if the only control statement is specified by PARM= on the EXEC statement.

SYSPRINT DD statement

Specifies the output message data set. This is a required DD statement and usually is a SYSOUT data set.

SYSUDUMP DD statement

Specifies the abend dump data set. Usually specifies a SYSOUT data set. Although not required, we strongly urge you to always include this DD statement, so that we can help you diagnose error conditions. If you have a debugging aid product on your system that would prevent the desired dump, please add the appropriate one of these statements to the JCL so that a fully-formatted dump is produced.
