Is your application or WebSphere MQ for z/OS running slowly?
If your application is running slowly, this could indicate that it is in
a loop, or waiting for a resource that is not available.
- Is the problem worse at peak system load times?
- This could also be caused by a performance problem. Perhaps it is because
your system needs tuning, or because it 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 you to occur at some
other time.)
- Does the problem occur when the system is lightly loaded?
- If you find that degrading performance 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 manifest itself as a
problem that only occurs when specific queues are accessed.
- Is WebSphere MQ for z/OS running slowly?
-
The following symptoms might indicate that WebSphere MQ for z/OS is running slowly:
- If your system is slow to respond to commands.
- If 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.
