Hi I know that you can to configure the LOAD_BALANCER option for connect to RAC DATABASE in the tnsnames.ora of the client connection. But in the server , there is any entry in the init.ora or in the listener.ora to configure this type of rac network configuration My problem its that i have a RAC DATABASE of 6 nodes in Oracle 9.2.0.6 . The client have a Load balancer configuration in your tnsnames.ora . But if the load of the system is high, when i check the gv$session of active sessions group by for inst_id i see that a server have the double of active connections that the others Thanks
