There are a series of tools and parameters of interest to the
|
||
administrator of a Berkeley DB Java Edition database.
|
||
These tools and parameters are useful for tuning your
|
||
JE database's behavior once it is in a production
|
||
setting, and they are described here. This chapter, however, does not describe backing up and restoring your
|
||
JE databases. See
|
||
<a class="xref" href="backuprestore.html" title="Chapter 11. Backing up and Restoring Berkeley DB Java Edition Applications">Backing up and Restoring Berkeley DB Java Edition Applications</a> for information on how to perform those procedures.

<p>
|
||
JE applications can be controlled through a
|
||
Java properties file. This file must be placed in your environment home directory and it must be named
|
||
<code class="filename">je.properties</code>.
|
||
</p>
|
||
<p>
|
||
The parameters set in this file take precedence over the configuration behavior coded into the
|
||
JE application by your application developers.
|
||
</p>
|
||
<p>
|
||
Usually you will use this file to control the behavior of JE's background threads, and to control the size of your
|
||
in-memory cache. These topics, and the properties parameters related to them, are described in this chapter.
|
||
Beyond the properties described here, there are other properties identified throughout this manual that may be
|
||
of interest to you. However, the definitive identification of all
|
||
the property parameters available to you is described in the javadoc for the
|
||
<code class="classname">EnvironmentConfig</code> class. Each property has a
|
||
<code class="classname">String</code> constant in <code class="classname">EnvironmentConfig</code> that
|
||
describes its meaning, default value, and so forth.
