Hi,
Sometimes You can get “TNS-12221: TNS:illegal ADDRESS parameters ” error.
Details of error are as follows.
TNS-12221: 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 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.
