The MQ Adapter has monitoring facilities at both the system-wide level and by queue. These statistics may be used to evaluate the usage of utility subtasks and the number of IDMS MQI calls and the number of calls that are made to IBM MQ.
Use the output of the following DCMT commands to monitor MQ Adapter activity at runtime:
COMMAND
DESCRIPTION
EXAMPLE
DCMT DISPLAY
STATSTICS SYSTEM
Displays existing system statistics and the following IDMS MQ statistics:
  • Number of calls to MQI
  • Number of calls to IBM MQ
  • Number of MQOPENs commands issued
  • Number of MQCLOSEs commands issued
  • Number of MQPUTs commands issued
  • Number of MQGETs commands issued
  • Subtask statistics
  • High-water mark for concurrent subtask use
  • Number of utility subtasks available
  • Number of times a subtask is unavailable
Note:
The INTERVAL and ROLL functionality is not supported for CA IDMS MQ statistics.
DCMT DISPLAY STATSTICS SYSTEM
DCMT D STAT MQ
Displays the IDMS MQ statistics only (see the DCMT DISPLAY STATISTICS SYStem command for MQ statistics list).
DCMT D STAT MQ
DCMT D STAT MQ QUEUES
Displays IDMS MQ statistics and the queue statistics for each IDMS MQ queue that has been accessed in the CV:
  • Number of MQOPENs commands that are issued for a queue
  • Number of MQCLOSEs commands that are issued for a queue
  • Number of MQPUTs commands that are issued for a queue
  • Number of MQGETs commands that are issued for a queue
DCMT D STAT MQ QUEUES
DCMT D STAT
MQ QUEUE
<queuename>
Displays IDMS MQ queue statistics for the named queue only (see the DCMT DISPLAU STAT MQ QUEUES command for queue statistics list),
