If the problem seems to occur only at specific times of the day, consider what's happening in the system at that time:
- How many MASs are active? Where are they located and how are they communicating
with the CMAS that is managing them? Have any MASs or CMASs recently
become active and begun communicating with other address spaces?
- Could the problem be related to system loading? Is the number of MASs
(with associated resource activity) at its peak? If your CICSPlex® SM environment
extends across more than one time zone, remember that the time of peak system
usage may vary.
- What type of monitoring, workload management, or analysis definitions
are in effect? Keep in mind that the use of time periods can cause definitions
to automatically become active or inactive at preselected times of the day.
