Below aliases from tnsnames.ora file

dware2
dwareSo of course "duarfnam" is not found
12533, 00000, "TNS:illegal ADDRESS parameters"
// *Cause: An illegal set of protocol adapter parameters was specified. In
// some cases, this error is returned when a connection cannot be made to the
// protocol transport.
// *Action: Verify that the destination can be reached using the specified
// protocol. Check the parameters within the ADDRESS section of
// TNSNAMES.ORA.  Legal ADDRESS parameter formats may be found in the
// Oracle operating system specific documentation for your platform.
// Protocols that resolve names at the transport layer (such as DECnet object
// names) are vulnerable to this error if not properly configured or names are
// misspelled.
