OPTIMIZE: Overriding the SETSYS ABARSOPTIMIZE command

Explanation: OPTIMIZE(option) is used to override the usage of the SETSYS ABARSOPTIMIZE command. The OPTIMIZE parameter is passed to and used by DFSMSdss when backing up level 0 DASD data sets.

The valid specifications for the option value are:

If value is 1, then DFSMSdss reads one track at a time
If value is 2, then DFSMSdss reads two tracks at a time
If value is 3, then DFSMSdss reads five tracks at a time
If value is 4, then DFSMSdss reads one cylinder at a time

Defaults: The default value for option is the value specified on the SETSYS ABARSOPTIMIZE command. If SETSYS ABARSOPTIMIZE was not specified, then this parameter defaults to 3.
