To configure a dbcache size larger than 4 gigabytes, add the nsslapd-dbncache attribute to cn=config, cn=ldbm database, cn=plugins, cn=config between the nsslapd-dbcachesize and nsslapd-db-logdirectory attribute lines.

Set this value to an integer that is one-quarter (1/4) the amount of memory in gigabytes. For example, for a 12 gigabyte system, set the nsslapd-dbncachevalue to 3; for an 8 gigabyte system, set it to 2.
