Spool function			Used to store SQL statements when an error occurred and resend the statements when the communications are recovered from the error.
	Spool capacity		2 MB *9
Operation Log function			The following three types of logs can be recorded. • Execution Log: Log for tracing the executions of the DB Connection Service. • Debug Log: Detailed log for SQL statement executions of the DB Connection Service. • SQL Execution Failure Log: Log for execution failures of SQL statements in the DB.
DB Connection Service shutdown function			Used to shut down the DB Connection Service after automatically saving the Operation Log files into the SD Memory Card.
