Issue/Introduction

After installing DMLO in IDMS release 19.0; executing DMLO at the
Enter Next Task Code causes it to fail with message
DC021002 TASK:DMLO; LOAD OF USDMLXIT FAILED.

Resolution

From IDMS 18.0 and later USDMLXIT is now  dynamically loaded, so it needs a sysgen PROGRAM definition.

IDMS 19.0 DMLO Configuration steps include adding or updating SYSGEN PROGRAM definitions.
These are in JOB13 step SGENUSD referencing CAGJSRC member USDSYSGN or USDSYSNN.

Job14 adds these definitions to System 99.

Job16 generates Demo SYSTEM 90 after copying all TASK and PROGRAM definitions from SYSTEM 99.

The same must be done for the SYSTEM that you execute (I.E. copy Programs and Tasks from system 99 to your system and GENERATE).

After completion of these steps; recycle CV and retest.

If PROGRAM USDMLXIT was properly added to your SYSTEM, DCMT D PRO *.USDMLXIT should display the Program Definition Element (PDE) for the program which is created from the sysgen definition.

Example:

   DCMT D PRO *.USDMLXIT
