Exchange logs

I have a Unity server 4.0(5) running on box exchange 2000. There is a directory on the D: drive called MDBDATA that continously writes 5MB log files. Does anyone know what these log files are and how to turn them off?

Thanks,

Glenn

Re: Exchange logs

Glenn,

These are transaction logs for Exchange. Exchange writes each transaction to a file before writing it to the database. In case of a failure these logs can be used to restore the database to a consistent state. The logs will be purged when the Exchange database is backed up. The other option is to enable circular logging. Circular logging allows the transaction logs to be deleted when the transactions are committed to the database as opposed to waiting for a backup. The downside to circular logging is if you have to restore an Exchange database, changes since the restore will be lost. Circular logging is disabled by default. If you would like to enable it, take a look at the following link.
