Database Plug-in Attributes
Chapter 3 Plug-in Implemented Server Functionality Reference 167
nsslapd-db-logbuf-size
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 signficantly increase throughput in the presence of long
running transactions, highly concurrent applications, or transactions producing
large amounts of data.
The nsslapd-db-logbuf-size attribute is only valid if the
nsslapd-db-durable-transactions attribute is set to on .
nsslapd-db-logdirectory
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, serverRoot/slapd-serverID/db . For fault-tolerance and performance
reasons, you may want to 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, you add the attribute to dse.ldif .
For more information on database transaction logging, see chapter 12, “Monitoring
Server and Database Activity,” in the Red Hat Directory Server Administrator’s Guide.
