Thank you Beat;

I configured the local listener and it solved my problem.

Hello Robert

We had this error by not configuring the local_listener in the spfile.
What happens: If the listener initiates a failover to the second node,
because it is not serving the required service the domain name is not
provided to the client. When you configure load_balance=yes in your
tns_names string this ends in a intermittent problem behaviour. As long
as yous tay in the same dns domain no problem. When you define a
local_listener the domain will as well be provided.
2'nd Workaround: insert the VIP IP as alias into your dns that every
client in your network can access the vip without domain.

Regards Beat
