NETNetworkError 208

Post by KI - stefan » Thu 12 Jan 2006 16:46

We get this error message sometimes using mobil framework 3.1 for Ora.
What does that mean - how can we avoid it.

This error is equivalent to

ORA-03113 end-of-file on communication channel
Cause: An unexpected end-of-file was processed on the communication channel. The problem could not be handled by the Net8, two task, software. This message could occur if the shadow two-task process associated with a Net8 connect has terminated abnormally, or if there is a physical failure of the interprocess communication vehicle, that is, the network or server machine went down.

We changed to version 3.20 and made some changes to reconnect.
When we get the Network Error 208, we always see it.
But often we do not get the 208 Error - the database call
does not return and even we get no timeout - time is about
3 to 10 minutes.
But after that time we get an result from DB without retrying.
What happens here ?? - How can we check anything around
to find the reason. There a no locks on the DB, the DB server
is running fine.

Thanks for quick answer - the problem is actual very urgent.

This error can happen if TCP connection is broken. Or possibly Oracle server break connection due to errors in traffic. Or this can happen if you try to execute unsupported operation (for example if you work with BLOB/CLOB column through RAW/LONG parameter. OraDirect .NET cannot check this)
