DYNCAT Commands
For more information about sample reports produced using the SCRATCH
command, see the chapter "CA Dynam Report Examples."
The format of the command is shown below.
SCRATCH [ NODEQ ]
[ NOLIST ]
[ VAULT= {YES|NO } ]
NODEQ
Optional operand. Eliminates periodic dequeues during the SCRATCH run.
Catalog buffers need not be refreshed, thereby shortening the run time.
Note, however, that if NODEQ is specified, almost all other tasks that share
the Catalog or Audit files can be expected to wait until SCRATCH is complete.
NOLIST
VAULT=
Optional operand. Creates only SCRATCH tape listings -- not regular dataset
reports.
Optional operand.
YES
NO
Specifies that a volume residing in a vault other than the
main tape vault will be eligible for scratch. Once an entire
volume becomes eligible for scratch, a Vault Movement
Exit Report will show the volume moving to the main tape
vault.
This is the default. Specifies that a volume must reside in
the main tape vault to be considered eligible for scratch.
Note: The main tape vault is always vault 'A'.
The following tapes will be made available as scratch tapes:
• Tapes that have exceeded all retention criteria -- that is, tapes whose
cycle retention and/or date retention and/or as-of-date cycle retention has
passed.
• All tapes created under data set names locked for output.
• All tapes created under $TEST job processing.
• All tapes opened for output, but never closed, which have been open
longer than the number of hours specified in the DYNAM/T option record.
The default is 8 hours.
• All work tapes not released by TLBL or Catalog option that have exceeded
the standard work tape retention.
• All tapes scratched by RERUN option.
