My archivelogs are not getting transferred to the DR side every time I switch a log. I have to keep copying the archivelogs onto the DR system then register them.

I have 3 redo logs groups on both sides and 4 standby redo log groups.

I might be getting confused here but don't the standby redo logs get written to by the Production redo logs?

I've tried populating data on Production to see what happens.
Production alert log:

Any help would be great
