Red Hat Directory Server 8.0 Configuration, Command, and File Reference

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
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 Description
Entry DN cn=config, cn=ldbm database, cn=plugins,
cn=config
Valid Range 512 bytes to 64 kilobytes
Default Value 8KB
Syntax Integer
Example nsslapd-db-page-size: 8KB
4.1.16. nsslapd-db-spin-count
This attribute specifies the number of times that test-and-set mutexes should spin without
blocking.
