The next message would have been:

DC040101 Vnn LOCK MANAGER STORAGE ESTIMATE =  xxxx

Environment

Release: 19.0

Cause

Specifying a very large value for SUBTASKS parameter in the PARM statement which requires a lot of storage:

    PARM='MT=N,SUBTASKS=50' 

In this case this is used to specify the number of utility subtasks for the IDMS MQ Adapter.

 

Resolution

Apply PTF LU16711 if not already applied.

 Specify a lower value for SUBTASKS like 3 or 4.

Additional Information

See documentation section Configure the MQ Adapter in heading Specify the Number of Utility Subtasks and section Coding Options as Freeform Parameters.
