Checkpoint and Spool Data Sets

CA Spool must have one checkpoint data set and one or more spool data sets. The CA Spool checkpoint data set is allocated on a direct access volume with the default data set name CAI.ESFCHKPT. The CA Spool data sets are allocated on direct access volumes. The default spool data set name is CAI.ESFSPOOL. The structure and organization of the checkpoint and spool data sets and the data set names are specified by the CA Spool parameter data set.

A secondary checkpoint data set can be defined, which is used as a duplex copy of the primary checkpoint data set. Therefore, it can be used for manual recovery in case the primary checkpoint data set becomes unusable.
