Database Plug-in Attributes
164 Red Hat Directory Server Configuration, Command, and File Reference • May 2005
nsslapd-db-debug
Specifies whether additional error information is to be reported to Directory
Server. To report error information, set the parameter to on . This parameter is
meant for troubleshooting; enabling the parameter may slow down the Directory
Server.
nsslapd-db-durable-transactions
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 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, you add the attribute to dse.ldif .
This attribute is provided only for system modification/diagnostics and should
be changed only with the guidance of Red Hat Technical Support or Red Hat
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, see chapter 12,
“Monitoring Server and Database Activity,” in the Red Hat Directory Server
Administrator’s Guide.
