What Is the Trace Route Utility?
The Trace Route Utility (TRCROUTE) is a new feature of SQL*Net release 2.3. It enables administrators to discover what path or route a connection takes from a client to a server. It TRCROUTE encounters a problem, it returns an error stack to theclient instead of a single error. These additional error messages make troubleshooting easier.
Note: TRCROUTE does not function on nodes using releases of SQL*Net earlier than release 2.3.
For more information about TRCROUTE, see Chapter 5, "Trace Route Utility".
