nsslapd-db-durable-transactions

when to write transactions to disk

Description

Indicates whether database transaction log entries are immediately written to the disk. The database transaction log contains a sequential listing of all recent database operations and is used for database recovery only.

With durable transactions enabled, every directory change is physically recorded in the log file and is therefore able to be recovered in the event of a system failure. However, the durable transactions feature may also slow down the performance of Directory Server. With durable transactions disabled, all transactions are logically written to the database transaction log but may not be physically written to disk immediately. If there is a system failure before a directory change is physically written to disk, that change is not recoverable.
