# $OpenLDAP$
# Example DB_CONFIG file for use with slapd(8) BDB/HDB databases.
#
# See the Oracle Berkeley DB documentation
# <http://www.oracle.com/technology/documentation/berkeley-db/db/ref/env/db_config.html>
# for detail description of DB_CONFIG syntax and semantics.
#
# Hints can also be found in the OpenLDAP Software FAQ
# <http://www.openldap.org/faq/index.cgi?file=2>
# in particular:
# <http://www.openldap.org/faq/index.cgi?file=1075>
# Note: most DB_CONFIG settings will take effect only upon rebuilding
# the DB environment.
# Set the database in memory cache size.
#
# set_cachesize <gbytes> <bytes> <ncache>
# Sets the database in memory cache size.
# Database entries and indexes will be stored in this cache to
# avoid disk access during database read and write operations.
# Tuning this value can greatly effect your database performance.
# The parameters are:
# <gbytes>: The number of gigabytes of memory to allocate to the cache.
# <bytes>: The number of bytes of memory to allocate to the cache.
# <ncache>: The number of cache segments to use. If this value is set to
# 0 or 1 then Berkeley DB will try to allocate one contiguous section
# of memory for the cache. If this value is greater than 1, the cache
# will be split into that number of segments.

# Sets the database startup flags.
#
# set_flags <flag>
# There are various flag options that may be set. The DB_TXN_NOSYNC flag
# tells the database not to immediately flush transaction buffers to disk.
# Setting this flag can help speed up database access during periods of
# database write activity BUT at expense of data safety. Enable it only
# to load data with slapadd, while slapd is not running.

# This value should be increased as the number of database files increases
# (tables and indexes).
set_lg_regionmax %%db_log_region_max

# one log file. This value should be at least four times the size of
# set_lg_bsize.

# cache it will be flushed to disk.

# set_lg_dir /usr/local/var/openldap-logs

# database files. This both improves reliability (for disastrous
# recovery) and speed of the database.
