Fast Path DEDB area data sets (ADS) encryption coexistence considerations

The DEDB Alter utility has requirements for coexistence in IMS 15.

Make sure all the IMS systems that share encrypted Fast Path ADS meet the following requirements:

All the IMS systems are IMS 15 with APAR PI83756 installed.
All the IMS systems are using Fast Path 64-bit buffers.
All the z/OS systems are z/OS 2.2 with OA50569 installed, or z/OS 2.3 and later.

If an encrypted Fast Path ADS is shared by an IMS system that is IMS 14or earlier versions, or IMS 15 without APAR PI83756, this IMS system will not be able to open or access the ADS. Message IEC161I with return code 122 will be displayed.
