At IDMS CV startup the NDVRSTRT task abends:
PREVIOUS TASK ABENDED WITH ABEND CODE D003 IDMS DC027001 V51 T122 D003 PROGRAM CHECK IN NDVRSTRT AT OFFSET 19AA02 PSW WAS 07BD0E00 80000002 DUMP OF TASK FOLLOWS
This abend is typically caused by defining the Distribution Loadlib in CDMSLIB rather than the Target Loadlib for the EDB product.
In your CV startup JCL, the CDMSLIB must include the EDB target loadlib or a copy of the EDB target loadlib CABG0LLT.
This abend indicates that you have included the Distribution loadlib CABG0LLD instead. Dlib members are not executable.
