HP-UX Directory Server 8.1 configuration, command, and file reference
3.4.1.6 nsslapd-db-circular-logging
This attribute specifies circular logging for the transaction log files. If this attribute is switched
off, old transaction log files are not removed and are kept renamed as old log transaction files.
Turning circular logging off can severely degrade server performance and, as such, should only
be modified with the guidance of HP Technical Support or HP Professional Services.

3.4.1.8 nsslapd-db-durable-transactions
This attribute sets 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
will always be physically recorded in the log file and, therefore, able to be recovered in the event
of a system failure. However, the durable transactions feature may also slow the performance
of the Directory Server. When durable transactions is disabled, all transactions are logically
written to the database transaction log but may not be physically written to disk immediately.
If there were a system failure before a directory change was physically written to disk, that
change would not be recoverable. The nsslapd-db-durable-transactions attribute is
absent from dse.ldif. To disable durable transactions, add the attribute to dse.ldif.
This attribute is provided only for system modification/diagnostics and should be changed only
with the guidance of HP Technical Support or HP Professional Services. Inconsistent settings of
this attribute and other configuration attributes may cause the Directory Server to be unstable.
For more information on database transaction logging, refer to the "Monitoring Server and
Database Activity" chapter in the HP-UX Directory Server administrator guide.
