HALDB support for 8-GB OSAM data sets enhancement coexistence considerations

The HALDB support for 8-GB OSAM data sets enhancement introduces some specific considerations for coexistence with IMS 14.

This enhancement supports coexistence with IMS Version 13 systems in data sharing environments only if SPE APAR PI23918 has been applied to all the IMS Version 13 resident libraries (RESLIBS) that access the RECON data set. The maintenance enables HALDB support for 8-GB OSAM data sets for IMS Version 13. The MINVERS value in the RECON data set must be 14.1 or later with the CDSLID value set to 2.
