Using multitasking with tape stacking or cabinet copies
In
BMC AMI Copy
version 9.2 and earlier, a GROUP YES multitasking copy with STACK YES or STACK CABINET on the OUTPUT descriptor stacks image copies on a tape or DASD for a cabinet copy until the end of group processing.
BMC AMI Copy
then deallocates the tape or cabinet copy. Subsequent multitasking copies with the same OUTPUT descriptor stack image copies on a different tape or cabinet copy.
In BMC AMI Copy version 10.1 and later, BMC AMI Copy does not terminate stacking on a tape or cabinet copy for a given OUTPUT descriptor at the end of group or set processing if the OUTPUT descriptor is referenced by a COPY statement for a later group or set. (A set is a set of multitasking GROUP NO COPY statements in the job.) The same tape or cabinet copy is used for all spaces. When BMC AMI Copy detects that a stacked tape or cabinet output is not used in a future group or set, BMC AMI Copy deallocates the device.
