Oracle's archived logs = MS transaction log dump files.

If you enable "truncate log on chkpt", the transaction log will be truncated every time there is checkpoint.
Another way to do is to setup thresholdaction, it will be fired up automically when the space reach certain percentage defined.

And thus you discover the inane mechanism that SQL Server inherited from Sybase, by which both try to do concurrency.

Guess what happens when a long running transaction marks the log near the end, and not too long afterward the log needs truncated?

If memory serves, ( hasn't worked too well lately :) the database will hang. It may just truncate back to the mark, and start from there, but you always have the possibility of another long transaction starting.

Can't remember the details, but what I do remember clearly is that it is a process that has to be closely watched, and I didn't particularly care for the way it worked.
