Dear Chinedu,
Everything is configured like you said. And strange is that this works about 6
months.

Dear Tiran;
I have come across a similar problem before. For this to work, A tnsnames entry
should be present in each database for connection both ways ie. a tns names
entry from the standby to the primary and vice versa.
In addition, configure a static listener on both nodes to stand in for the tns
entries.
Try and feedback.
Cheers
