<adm:synopsis>
|
The
|
<adm:user-friendly-name />
|
uses the Berkeley DB Java Edition to store user-provided data in a local
|
repository.
|
</adm:synopsis>
|
<adm:description>
|
It is the traditional "directory server" backend and is similar to
|
the backends provided by the Sun Java System Directory Server. The
|
<adm:user-friendly-name />
|
stores the entries in an encoded form and also provides indexes that
|
can be used to quickly locate target entries based on different
|
kinds of criteria.

If set to "false", then the eviction keeps internal nodes of the underlying

information.

</adm:synopsis>
|
<adm:description>
|
Changes to this property do not take effect until the backend is
|
restarted. It is recommended that you also change this property
|
when you set db-evictor-lru-only to false. This setting controls
|
the number of Btree nodes that are considered, or sampled, each
|
time a node is evicted. A setting of 100 often produces good
|
results, but this may vary from application to application. The
|
larger the nodes per scan, the more accurate the algorithm.
|
However, setting it too high is detrimental; the need to consider
|
larger numbers of nodes for each eviction may delay the completion
|
of a given database operation, which will impact the response time
|
of the application thread.

If this value is set to "false", then all data written to disk

be cached for a period of time by the underlying operating system

performance, but could cause the most recent

changes to be lost in the event of an underlying OS or hardware

failure (but not in the case that the OpenDS Directory Server or

the JVM exits abnormally).
