To subscribe to this RSS feed, copy and paste this URL into your RSS reader. I'm an Oracle dveloper, I use Oracle databases every day, no Listener or TNS problem, I have problem with the remote databases only, but I replaced the 64bit PBI with 32bit version and I can connect to remote databases too, I think my Oracle 10.2 client and 64bit PBI are incompatible in remote connection. To resolve this, try speeding up the connection by using exact addresses instead of names and increase the INBOUND_CONNECT_TIMEOUT_listener_name parameter in the listener.ora file. The number of trace files for client tracing. Perform the tnsping and see if what packet are being sent, what dns lookup are being made, what route is being taken. It might have the same real (old) IP, or could be using you PC name, which might be working. When the size is reached, the trace information is written to the next file. Hence, systemstate dumps can be useful even when the time needed to generate them exceeds the period of a single timeout e.g. cursor: pin S wait on X What IP is the listener/connection using at the moment? If the test was not successful, then do the following: Ensure the database and listener are running, and then click Test. When MULTIPLEX is set to ON, session multiplexing is enabled.
