Starting with Red Hat Directory Server 10.1.1, the cache auto-sizing feature is enabled by default.
In some deployments, one might want to manually set a value for the entry cache of a given backend.
For instance a customer has an instance with two suffixes:
- dc=example, dc=com
The suffix o=NetscapeRoot stores the Admin Server configuration data. It has typically only a few hundreds of entries.
The other suffix could have millions of entries.
In such case, the entry cache should be much lower for the NetscapeRoot backend.
But the entry caches will have the same value if they are automatically computed:
$ grep "nsslapd-cache-autosize:" dse.ldif nsslapd-cache-autosize: 20 $ $ grep nsslapd-cachememsize: dse.ldif nsslapd-cachememsize: 134217728 nsslapd-cachememsize: 134217728 $
Red Hat Directory Server 10.1.1 or later
