I know what you are thinking. Not another standby monitoring script, right?
There’s plenty of them out there already and what makes this one any different?
You are probably correct and there’s probably nothing different about this.
Having to work with environments that are inconsistent such as manual standby, dataguard without broker, dataguard with broker,
I have been obsessed to create standby SQL which can accommodate any environment and can be run from primary or standby.

Note: Apply Lag is NOT really 1 hour.
Look at the time difference between SQL*Plus sessions.
