ORA-12222: TNS:no support is available for the protocol indicated

Reason for the Error

The protocol requested in the ADDRESS portion of the connect descriptor identified through the net service name is not available. If the supplied ADDRESS is typographically correct then support for that protocol is not installed.

Solution

Install support for the protocol or correct typographical error, as appropriate. Note: if the supplied address was derived from resolving the net service name, check the address in the appropriate file (TNSNAMES.ORA, LISTENER.ORA) or in the directory server.
