3.4.1.14. nsslapd-db-logfile-size
This attribute 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 10 megabytes is used. The maximum size is an unsigned 4-byte value.
Parameter
Description
Entry DN
cn=config, cn=ldbm database, cn=plugins,
cn=config
Valid Range
0 to unsigned 4-byte integer
Default Value
10MB
Syntax
Integer
Example
nsslapd-db-logfile-size: 10 MB
3.4.1.15. nsslapd-db-page-size
This attribute 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 64 kilobytes. If the page size is not explicitly set, Directory
Server defaults to a page size of 8 kilobytes. Changing this default value can have a significant
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.
Parameter
