SQLServerF1

ORA-12215: TNS:poorly formed PREFERRED_NAVIGATORS Addresses in TNSNAV.ORA
Cause: Address binding for PREFERRED_NAVIGATORS entry is improperly entered. entry.
Action: Check your PREFERRED_NAVIGATORS entry and fix it in TNSNAV.ORA
ORA-12216: TNS:poorly formed PREFERRED_CMANAGERS addresses in TNSNAV.ORA
Cause: Address binding for the PREFERRED_CMANAGERS entry in the client’s TNSNAV.ORA file is improperly entered.
Action: Define the ADDRESS as part of the PREFERRED_CMANAGERS binding.
ORA-12217: TNS:could not contact PREFERRED_CMANAGERS in TNSNAV.ORA
Cause: There is a syntax error in the PREFERRED_CMANAGERS entry, or addresses specified are wrong, or the intended Connection Managers are unavailable.
Action: Check the PREFERRED_CMANAGERS entries in the client’s TNSNAV.ORA file and correct them or talk with your network administrator to determine if the specified Connection Managers are available. Verify that the Interchanges are active by using the INTCTL STATUS command.

ORA-12218: TNS:unacceptable network configuration data
Cause: Poorly formed network configuration data. For example, a PREFERRED_CMANAGERS entry may have an incorrect CMANAGER_NAME in the client’s TNSNAV.ORA file. Or an Interchange downtime parameter (TIMEOUT_INTERVAL) on the Navigator may be set to zero in INTCHG.ORA.
Action: Check the entries in TNSNAV.ORA and the Interchange configuration files and correct them. If necessary, talk with your network administrator to determine if the specified Interchanges (Connection Managers) are available and properly configured. Use the Oracle Network Manager to generate the configuration files if necessary.
ORA-12219: TNS:missing community name from address in ADDRESS_LIST
Cause: This error occurs when an ADDRESS_LIST has some ADDRESSes in it that have no COMMUNITY component and others that do have a COMMUNITY component.
Action: Check that in the connect descriptors you are using either all the ADDRESSes have a COMMUNITY component or all do not.
ORA-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.

ORA-12222: TNS:no support is available for the protocol indicated
Cause: 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.
Action: 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.
ORA-12223: TNS:internal limit restriction exceeded
Cause: Too many TNS connections open simultaneously.
Action: Wait for connections to close and re-try.
ORA-12224: TNS:no listener
Cause: The connection request could not be completed because the listener is not running.
Action: Ensure that the supplied destination address matches one of the addresses used by the listener – compare the TNSNAMES.ORA entry with the appropriate LISTENER.ORA file (or TNSNAV.ORA if the connection is to go by way of an Interchange). Start the listener on the remote machine.

Above are list of Oracle Database Errors or Warnings from Error ORA-12215 to ORA-12224 received while performing certain operation against Oracle Database or related products.
