Hi Tim,

Do you know of anyone implimenting a transaction log file in DBISAM?
If not could you suggest a location in the code that would be appropriate to impliment this?

Our customers backup each night, be we would also like to have an option to 'playback' the transactions
from the day up until the crash(if it happens).

Any help would be greatly appreciated

Cheers

Graeme,

I'm sure there is someone doing so because we've had questions to that
effect before.  However, I can't tell you specifically if someone is doing
so or not.

The best place to do so would be via the trigger events in the TDBISAMEngine
component:

See the "Triggers" section.

Not a bad idea.  As long as the performance is acceptable, it never hurts to
be extra-prepared for emergencies.
