PTF RO92126 adds support for PDSE V2 data and program object libraries in
Backup, Archive and Restore functions.
This support is enabled by adding a value of "PV2" to Sysparm USEDSSIO.
For those customers who have specified " USEDSSIO* " PV2 is automatically included.
PDSE Version 2 data sets will be backed up, archived and restored using existing SMS and DSS defaults.
