Nsslapd-Db-Transaction-Logging - Netscape DIRECTORY SERVER 6.02 Configuration Manual

Database Plug-in Attributes
If you do not define this attribute or set it to a value of 0, transaction batching will
be turned off and it will be impossible to make remote modifications to this
attribute via LDAP. However, setting this attribute to a value greater than 0 causes
the server to delay committing transactions until the number of queued
transactions is equal to the attribute value. A value greater than 0 also allows you
to modify this attribute remotely via LDAP. A value of 1 for this attribute allows
you to modify the attribute setting remotely via LDAP, but results in no batching
behaviour. A value of 1 at server startup is therefore useful for maintaining normal
durability, while also allowing transaction batching to be turned on and off
remotely when desired. Bear in mind that the value you choose for this attribute
may require you to modify the
sufficient log buffer size for accommodating your batched transactions.

Specifies whether transaction logging is on or off. Turning transaction logging off
can considerably improve Directory Server performance but at the risk of data loss

necessary to set up other database recovery procedures.
