COBOL mapping issue using versioning

Products

• IDMS

Issue/Introduction

User is having issues with a version 2 of a map and version 2 of a program – Map was created as copy of Version 1 all, program compiled with Cobol 6. Version 1 of the map used by version 1 of the program also compiled with Cobol 6. Users are getting corrupt data on map version 2, in the 12^th of an occurs 15. Looking at MAPC there are no discernable differences in the map definition that would account for this error. 

Environment

Release : 19.0

Component : IDMS MAPPING

Resolution

DCUF TEST works with versioned entities.  In testing DCUF TEST with non-versioned entities, such as a COBOL program,  some additional preparation is necessary.

If a DCMT VDP xxxxxxxx VERSION 2 ASM|COBOL is issued , and a DCMT DIS PRO xxxxxxx is issued:

   DIS PRO xxxxxxxx V 2.                                       
Program Name xxxxxxxx                 Ddname          V0002   
Type                  PROGRAM             Type               LOADLIB       
Language          ASM                       Dictname                      
Size (bytes)       00006480               Dictnode  

Note the Ddname to load version 2 of the module is V0002, and not CDMSLIB.

Tried the following:

Copied version 1 of a map to version 2 using MAPC, and compiled the map.

Pre-processed and compiled a program using version 2 of the map into a 'V0002' load library.

Added a V0002 DDname to the CV JCL, citing the 'V002' load library, and cycled CV.

Defined a version 2 of the program (DCMT VDP xxxxxxxx Version 2 COBOL, or SYSGEN definition/CV-cycle both work).

Issued DCUF TEST 2. 

Entered the task code to invoke the program, and version 2 of the program and map were loaded and utilized.
