Example
3.4.1.12. nsslapd-db-logbuf-size
This attribute specifies the log information buffer size. Log information is stored in memory until the
buffer fills up or the transaction commit forces the buffer to be written to disk. Larger buffer sizes
can significantly increase throughput in the presence of long running transactions, highly concurrent
applications, or transactions producing large amounts of data. The log information buffer size is the
transaction log size divided by four.
The nsslapd-db-logbuf-size attribute is only valid if the nsslapd-db-durable-
transactions attribute is set to on.

Example
3.4.1.13. nsslapd-db-logdirectory
This attribute specifies the path and directory name of the directory containing the database
transaction log. The database transaction log contains a sequential listing of all recent database
operations and is used for database recovery only. By default, the database transaction log
is stored in the same directory as the directory entries themselves, /var/lib/dirsrv/
slapd-instance_name/db. For fault-tolerance and performance reasons, move this log file to
another physical disk. The nsslapd-db-logdirectory attribute is absent from dse.ldif. To
change the location of the database transaction log, add the attribute to dse.ldif.
For more information on database transaction logging, refer to the "Monitoring Server and Database
Activity" chapter in the Directory Server Administrator's Guide.
