....
I have tried to catch the exception when connection is failed.
For about 100 events I didn't catch (program is hanged ...)
one of them has the following exception (when doing oraConn.open, as I have
mentioned) :
error number : -2147467259
description : ORA-12638: Credential retrieval.

Does the above error is a clue to some problem ?

Thanks

The first result is currently a thread on Oracle's support forums, and
appears to be helpful - the thread discusses the value of
SQLNET.AUTHENTICATION_SERVICES.

If the computer's time varies from the Active Directory domain
controller's time by more than 5 minutes (the default), domain
authentication will fail, if the computer is a member of Active
Directory.

Hello,
I have changed SQLNET.AUTHENTICATION_SERVICES = (NONE).
It seems for a while (2 days) without any connection problems after I have
changed it (maybe just coincidence),
but the problem right now still exists
(task is hanged sometimes when connecting to the database).
Can I somehow doing tracing ? ... and what should I trace ?

Thanks
