You can access z/OS IDMS data sources with FOCUS running using the Computer Associates Distributed Database System (DDS) package. The adapter uses the data source table name and DDS node name specified in the Access File to call the local IDMS CV to access a second operating system through DDS. No special FOCUS software is required.

In all possible scenarios, the Master and Access File and FOCEXEC procedures must reside in the FOCUS environment.
