Single Server Recovery

If you are running a single server (with no redundancy), enable the transaction log. For maximum security, enable flushing of the transaction file. If this impacts performance too greatly, and recovering from backups is an option, you can turn flushing off.

You need to perform disaster recovery for a single server if any of the following occurs:

• Loss of a server
• DSA exits abnormally and there is no transaction file
• A power failure or a critical error in the operating system and the transaction file is not being flushed
• A disk failure

To perform disaster recovery in these cases, recover from backups.
