GRS Systems Response Time Critical

 

Suggested Actions

GRS response time exceeds the high threshold, usually 25 milliseconds. If no hardware problem is indicated, there is probably a bottleneck in one of the connected systems, causing the GRS token to become stalled. If the sysplex is a parallel sysplex, this kind of problem can be eliminated by changing to a GRS Star configuration, using the coupling facility to hold and exchange GRS data across all systems in the sysplex.
