oracle connection problem ORA-12569: TNS:packet checksum failure
Posted on 2004-04-14
We have someone outside our network trying to make a connection to our oracle database
He gets the "ORA-12569: TNS:packet checksum failure" error message.
Any idea what could be causing this error?
A google search gave me this result...
"ORA-12569: TNS:packet checksum failure
Cause: The data received is not the same as the data sent.
Action: Attempt the transaction again. If the error is persistent, turn on tracing and reexecute the operation"
I don't understand what they want me to do here...
Also, could this have anything to do with our firewall...I opened up the firewall to the ip addresses of the person making the connection and he is able to ping the server, but when he tries to make the oracle connection, he gets that error message. Any help would be greatly appreciated. Thanks!
