SEC_PROTOCOL_ERROR_TRACE_ACTION specifies the action that the database should take when bad packets are received from a possibly malicious client.
The database server ignores the bad packets and does not generate any trace files or log messages.
A detailed trace file is generated when bad packets are received, which can be used to debug any problems in client/server communication.
A minimal log message is printed in the alert logfile and in the server trace file. A minimal amount of disk space is used.
An alert message is sent to a DBA or monitoring console.
