PDSE Version 2 to be refitted to z/OS 1.12. In z/OS V2.1, PDSE processing is planned to be enhanced with a new format, PDSE Version 2. PDSE Version 2 will be designed to allow all unused space to be released, consolidate directory pages when possible, improve read performance, and reduce virtual storage utilization for PDSE processing. Also, the PDSE API is planned to support much larger members for PDSE data sets. The new limit on PDSE member size is planned to be over 125 times larger than the current limit in many circumstances, and substantially larger than the maximum supported size of a PDS member. These enhancements are intended to provide additional scalability and usability benefits of using PDSEs in place of PDSs, make it feasible to use PDSEs instead of multiple large sequential data sets, and help reduce the space required for PDSEs while improving performance for most PDSE read operations. Toleration of the new PDSE format is planned for z/OS V1.12 and z/OS V1.13.
