Chapter 4. Utility Functions 173
1st ed., 6/30/04 - 312579601
The Volume Report utility executes in the SCP batch job environment in CMS, or in
stand-alone mode in the POST/SAE environment. Stand-alone mode allows the
administrator to locate backup tapes when the ACS service machine cannot be started due
to the loss of a critical DASD data set.
Control Statement Syntax Conventions
The control statement for each utility program consists of a command (indicating the
utility function) followed by parameters, as applicable, in 80-character card-image
records. For more information about this syntax, see Appendix A, “Macros, Control
Statements, Utilities, and Commands Syntax Reference” on page 429.
Utility Syntax Conventions
Utility syntax is illustrated using syntax flow diagrams. For a complete description of this
syntax convention, refer to Appendix A, “Macros, Control Statements, Utilities, and
Commands Syntax Reference” on page 429.
Utility Environmental Requirements
Most of the utility functions require the HSC (Host Software Component) to be
operational. However, a few are either independent of the HSC or have special
environmental requirements:
• The Backup utility and the Journal Offload utility require the ACS service machine
SCP to be available, but not the HSC.
• The Restore utility likewise requires the SCP to be available and also requires the
HSC to be non-operational.
• The Activities Report utility, the Performance Log Reblocker utility, and the Volume
Report utility run in the CMS environment and are independent of the HSC and the
SCP. The Performance Log Reblocker can also be run in the MVS environment.
Note: For systems running VM ESA Version 2 or higher, utilities that are run in
CMS can run in XA or XC mode with SET 370ACCOM ON. For VM ESA below
Version 2, utilities run in CMS must run in 370 mode.
