You can manage temporary data sets with a function called virtual input/output (VIO). VIO uses DASD space and system I/O more efficiently than other temporary data sets.

You can use the BPAM, BSAM, QSAM, BDAM, and EXCP access methods with VIO data sets. SMS can direct SMS-managed temporary data sets to VIO storage groups.
