PDSE Type Data Set Considerations

The most important thing to remember is that serialized sharing of PDSE type data sets is limited to systems that belong to a single sysplex when GRS is active. There is no serialized protection when PDSE type data sets are shared with systems outside of a single sysplex. You can successfully share PDSE type data sets in a monoplex with the following settings:

Important: Attempts to share PDSEs across sysplex boundaries may result in data integrity exposures, corrupted PDSEs, or loss of data.
