2 rows selected


---------------

this means that it didn't reach the resource limites yet. What i can do to solve the problem ???

another important information is that connecting by the default listener LISTENER instead of the LISTENER_BKP_1 listener, the connection is completed successfully. There's enough SGA memory space too.


Tks,
