|The usage notes for ARCHIVE LOG currently state that using this command will |cause a database to lose a portion of its log sequence number (LSN) space, |and thereby hasten the exhaustion of valid LSNs. To put this space usage into |context, if you have a log file size of 100M and run ARCHIVE LOG every five |minutes, it will still take approximately 40 years to exhaust the valid LSNs. |Under most operating conditions, you will not experience an impact.
