During the Oracle database operation, the DBA should monitor the database's running log and table space usage, and discover the problems in the database as early as possible. Oracle Warning log file monitoring Oracle will log some of the database operations in the warning log file (alert_sid.log) during the run: The database is started, shut down, not default parameter when starting; Database redo log switching, recording the time of each switch,
