Is your application or system running slowly?
If your application is running slowly, it might be in a loop or waiting for a resource that is not available.
This might also indicate a performance problem. Perhaps your system is operating near the limits of its capacity. This type of problem is probably worst at peak system load times, typically at mid-morning and mid-afternoon. (If your network extends across more than one time zone, peak system load might seem to occur at some other time.)
A performance problem might be caused by a limitation of your hardware.
If you find that performance degradation is not dependent on system loading, but happens sometimes when the system is lightly loaded, a poorly-designed application program is probably to blame. This could appear to be a problem that only occurs when certain queues are accessed.
The following symptoms might indicate that WebSphere MQ is running slowly:
- Your system is slow to respond to MQSC commands.
- Repeated displays of the queue depth indicate that the queue is being processed slowly for an application with which you would expect a large amount of queue activity.
If the performance of your system is still degraded after reviewing the above possible causes, the problem might lie with WebSphere MQ itself. If you suspect this, contact your IBM Support Center for help.
