DFS2014 NUMBER OF RECORDS IN SMSGQ DATA SET HAS EXCEEDED UPPER THRESHOLD

Explanation
 IMS has established an upper threshold
for the number of records that can be assigned to the SMSGQ data set
before issuing this warning message. This threshold is some percentage
of the maximum number of records assignable before an automatic shutdown
is initiated.

System action
 IMS continues execution.

Programmer response
 You might want to reduce the queue usage
and avoid a possible shutdown. To determine the effect of this action,
examine the percentage of use displayed by the /DIS POOL command.
When the number of records assigned to the SMSGQ data set drops below
the lower threshold established by IMS, message DFS2017 is
issued.
