Oracle forced log archiving archive_lag_target forced archiving forced switching in the Data Guard environment, if the oracle database archiving frequency is too low, resulting in Data loss in the event of a fault, we can use the archive_lag_target parameter to force log switching and archiving. You can set a time (in seconds) for the archive_lag_target parameter to force the oracle database to switch and archive logs based on the time limit. The default value of this parameter is 0 (disabled ),
