This image shows client requests performance and Java Message Service (JMS) messages per server queue during a database switchover in a FMW stretched cluster.

One graph is titled "Request Performance (sec) vs. Time." The axes are Time and Avg Performance (sec). Request latency stays low, then spikes during the switchover window. A callout states "12:21:30-12:22:45 Period with client errors or bad performance ~ 1m15s."

Another graph is titled "FOD JMS MessagesCurrentCount per server's queue." The axes are Time and MessagesCurrentCount. Java Message Service (JMS) message counts increase steadily throughout the observation period, and level slightly during the switchover window.

Callouts mark the event window: "DB switchover starts 12:21:11" and "DB switchover ends 12:22:59." The latency spike and the "Period with client errors or bad performance ~ 1m15s" occur within this window, while JMS message counts continue to rise and then maintain trend.
