Red Hat DIRECTORY SERVER 7.1 User Manual

Database Plug-in Attributes
168 Red Hat Directory Server Configuration, Command, and File Reference • May 2005
nsslapd-db-logfile-size
Specifies the maximum size of a single file in the log in bytes. By default, or if the
value is set to 0 , a maximum size of 10Mbyte is used. The maximum size is an
unsigned 4-byte value. The value of this attribute can have significant impact on
performance, as it can be tuned to avoid extensive log switching in the event of
heavy entries.
nsslapd-db-page-size
Specifies the size of the pages used to hold items in the database in bytes. The
minimum size is 512 bytes, and the maximum size is 64Kbytes. If the page size is
not explicitly set, Directory Server defaults to a page size of 8Kbytes. Changing
this default value can have a signficant performance impact. If the page size is too
small, it results in extensive page splitting and copying, whereas if the page size is
too large it can waste disk space.
Before modifying the value of this attribute, export all databases using the
db2ldif script. Once the modification has been made, reload the databases using
the ldif2db script.
