VOLCNT

VOLCNT specifies the largest number of volumes that you expect UNLOAD PLUS to process when unloading a single data set.

For disk data sets, this option limits the values of the VOLUMES option. For both tape and disk data sets, the integer must be equal to or greater than the number of volumes that UNLOAD PLUS produces for the single largest output data set.

Additional considerations

Note the following considerations for VOLCNT:

  • For a nonspecific disk data set allocation, UNLOAD PLUS ignores VOLCNT. Use UNITCNT to request a multi-volume disk data set.
  • If you define the VOLUMES option for disk data sets, the default is the number of volumes in the list. To use the MVS default, set VOLCNT to 0.
  • If you are using SMS in your system, we recommend that you set VOLCNT to 0 if your ACS routines are set up to provide a volume count.
  • If you are unloading a large number of partitions, consider lowering the VOLCNT value from the default of 25 to avoid data set allocation limitations.

Specifying the default

You can specify the default for the VOLCNT command option in your installation options module by using the VOLCNT installation option. UNLOAD PLUS was shipped with a default value of 25 for this option. The command option overrides the default that is in the installation options module.
