java.lang.Object java.lang.Throwable java.lang.Exception java.lang.RuntimeException oracle.kv.FaultException
public class FaultException
Used to indicate an error condition that cannot normally be handled by the caller of the method, except by retrying the operation.
When the error occurred remotely and was due to an internally defined
server exception, the Throwable.getCause()
method will return null rather than
returning the internal exception, and the remote stack trace will not be a
part of the stack trace of this exception. This is because the internal
exception class is not present in the client library.
For logging, testing and debugging purposes, the full textual stack trace
of the remote exception, including any nested cause exceptions, is available
using the getRemoteStackTrace()
method, and the remote (or local)
exception's class name is returned by getFaultClassName()
. The
toString()
and Throwable.printStackTrace()
methods output the fault
class name and remote stack trace.
When the error occurred remotely, it will have already been logged and
reported on a remote KVStore node and will be available to administrators.
However, to correlate client and server errors and to make error information
easily accessible on the client, it is good practice to also log the error
locally. Errors that originated locally are not automatically logged and
available to administrators, and the client application is responsible for
reporting them. See wasLoggedRemotely()
.
