| ERROR | Protocol specific component of the address is incorrectly specified |
| CAUSE | The ADDRESS used to contact the listener is not correctly specified. This error occurs because the address fails to specify the destination of the listener. The address is well formed (for example, there are no missing parentheses) but it is missing a protocol specific component. For example, this is the error returned when the HOST component is missing from a TCP/IP address string. |
| ACTION | Edit the ADDRESS in LISTENER.ORA to include the required protocol-specific keywords. For more information about the keywords required by different protocol adapters, see the Oracle operating system specific documentation for your platform. |
