Open Database coexistence considerations

The IMS Universal drivers that come with IMS 15 can be used by Java™ applications that access IMS 14 databases as long as all the IMS systems are part of a mixed-version IMSplex that includes an IMS 15 system (along with its ODBM and IMS Connect address spaces).

Open Database Manager (ODBM) can only connect to the IMS systems that are of the same version as ODBM itself. In a mixed-version IMSplex, to limit ODBM connection to the IMS systems of the same version, list the eligible IMS systems as data stores in the CSLDCxxx member of the IMS PROCLIB data set.
