MAXSECD

Use MAXSECD to specify an upper limit on a secondary allocation extent by using the units (tracks or cylinders) that you specified for the SPACE command or installation option.

The resulting extent size might not exceed 65535 tracks.

Specifying a nonzero value for the integer establishes an upper limit for the secondary space allocation. A value of 0 indicates no limit. If the amount of required space that UNLOAD PLUS calculates is greater than the MAXSECD limit, UNLOAD PLUS issues message BMC50166W.

Additional considerations

The following considerations apply to the MAXSECD option:

  • UNLOAD PLUS ignores this option for referenced files.
  • Specifying the MAXSECD option when UNLOAD PLUS is automatically sizing a data set might result in additional units being allocated or might cause the data set to be undersized.
  • If you specify a value for the primary and secondary allocations for the SPACE command option, UNLOAD PLUS uses the SPACE value and ignores the value that you specify for MAXSECD.
  • When you are using the SMS-guaranteed space allocation, UNLOAD PLUS applies MAXSECD to all of the volumes that you specified in the VOLUMES command or installation option.

Specifying the default

You can specify the default for the MAXSECD command option in your installation options module by using the MAXSECD installation option. UNLOAD PLUS was shipped with a default value of 0 for this option. The command option overrides the default that is in the installation options module.
