Hello,
I'm sorry for top posting.
Ok, thank you very much, it works. I see that if I do many connections with
Toad to my Oracle RAC, with load_balance=on and failover=on, it always
attack to the first node. Is it normal? I understand that if I put the same
in the jdbc string (balance on and failover on), it will always attack to
first node, isn't it? I should delete "balance on" in all entries of jdbc
connections, isn't it?
Thanks beforehand.

Cheers...
