TNS-12221: TNS:illegal ADDRESS parameters



TNS-12221: TNS:illegal ADDRESS parameters..

Answer / guest

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 or in the directory. Legal ADDRESS
parameter formats may be found in the Oracle operating
system specific documentation or the Oracle Net
Administrator's Guide. Protocols that resolve names at the
transport layer are vulnerable to this error if not properly
configured or names are misspelled.
