the problem is:
when connect through sqlplus on client (windows), i got error randomly, and can connect randomly too.
please help, which configuration I was missed?

Answer 1

thanks,
this is 9204 with oracle cluster manager on rhas 2.1
by the way, the problem is resolved by specifying ip address on all tns entries, including tns entry which specified in local_listener and remote_listener.
but again I have problem with TAF.

got error when execute this on node3 and later I shutdown abort the racdb3 instance.
