Coupling Facility Structure to z/OS Requests Critical

 

Suggested Actions

The coupling facility performance has deteriorated severely. Check the status of the coupling links and the performance data for the coupling facility machine or LPAR. A link may be down or a processor may be offline or malfunctioning. If the coupling facility is in an LPAR with shared processors, the overall CPC may be fully loaded, thus causing the LPAR weights to come into effect. If more LPs are assigned to the CF than its share of total weight can support, try varying a LP offline.
