Oracle switchover using Data Guard broker(dgmgrl)

Hi, maybe lame question but is there a application outage during the switchover? Thanks

Hello sir, After performing switchover, how users will connect to primary database. Do we need to provide any information to them.

Hi, On doing switchover in 19c , it completes successfully but if I do show configuration afterwards , it gives the same apply lag error which you got. In your case it got resolved in some time, but in my case it doesn't go away automatically , it persists. Please suggest what could be the issue.
