Real-time Stacking

You can allow each scratch sub-pool that is defined in the TMOSCRxx member of hlq.CTAPOPTN as allowing real-time (dynamic) file stacking. If allowed, there are a few controls that you can place at the individual sub-pool level. These options can be broken down into the following groups.

• The first group controls how many files or how much data can be put onto one volume.
• The second group controls which files should be stacked and what to do if stacking is no longer possible.

Note: Only files with a label type of SL are eligible to be real-time stacked. Temporary SL data sets are excluded.
