TNS-02517: key smaller than requested size
Cause: The key returned by negotiation was smaller than the size requested by some service (either encryption or crypto-checksumming).
Action: The error is not normally visible. If the error persists, enable tracing to reproduce the problem and contact Oracle Support Services.
TNS-02516: No data available
Cause: A native service attempted to retrieve data but no data was available to be received.
Action: The error is not normally visible as it usually is only used to signal the end of a data stream. If the error becomes visible, enable tracing to reproduce the problem and contact Oracle Support Services.
TNS-02515: Encryption/crypto-checksumming: unknown control type
Cause: An encryption or crypto-checksumming algorithm "control" function was called, but did not recognize the "type" argument it was given. This message is not normally visible to the user.
Action: For further details, turn on tracing and re-execute the operation. If the error persists, contact Oracle Support Services.
TNS-02514: Invalid packet received
Cause: A process received a data packet which was not meant for the native services layer.
Action: If it is possible, enable tracing and attempt to reproduce the problem. In any event, contact Oracle Support Services.
TNS-02513: Requested data type does not match retrieved type
Cause: A service requested data whose type does not match that of the segment which was sent from the other process.
Action: If it is possible, enable tracing and attempt to reproduce the problem. In any event, contact Oracle Support Services.
TNS-02512: Invalid status received
Cause: A process received a value as a status flag which was unknown.
Action: If it is possible, enable tracing and attempt to reproduce the problem. In any event, contact Oracle Support Services.
TNS-02511: Invalid data type
Cause: The type of a piece of data that was received or to be transmitted did not correspond to any of the correct values.
Action: If it is possible, enable tracing and attempt to reproduce the problem. In any event, contact Oracle Support Services.
TNS-02510: Invalid numeric data type
Cause: The type of a piece of numeric data that was received does not correspond to one of the valid values.
Action: If it is possible, enable tracing and attempt to reproduce the problem. In any event, contact Oracle Support Services.
TNS-02509: Authentication: invalid process state
Cause: The state in which a process is running does not correspond to any of the values which are valid.
Action: If it is possible, enable tracing and attempt to reproduce the problem. In any event, contact Oracle Support Services.
TNS-02508: Encryption: server negotiation response in error
Cause: The server's response in negotiation was in error. This message is not normally visible to the user.
Action: For further details, turn on tracing and re-execute the operation. If the error persists, contact Oracle Support Services.
