+.B dbconfig <Berkeley DB setting>
+Specify a configuration directive to be placed in the
+.B DB_CONFIG
+file of the database directory. The
+.B dbconfig
+directive is just a convenience
+to allow all necessary configuration to be set in the
+.B slapd.conf
+file.
+The options set using this directive will only be written to the DB_CONFIG
+file if no such file existed at server startup time. This allows one
+to set initial values without overwriting/destroying a DB_CONFIG file
+that was already customized through other means. This directive may
+be specified multiple times, as needed. For example
+.RS
+.nf
+       dbconfig set_cachesize 0 1048576 0
+       dbconfig set_lg_bsize 2097152
