<p>Berkeley DB currently disallows the <a href="../api_reference/C/dbopen.html#open_DB_TRUNCATE" class="olink">DB_TRUNCATE</a> flag to the
|
||
<a href="../api_reference/C/dbopen.html" class="olink">DB->open()</a> method on VxWorks because the operations this flag represents
|
||
are not fully supported under VxWorks.</p>
|
||
<p>The <a href="../api_reference/C/dbsync.html" class="olink">DB->sync()</a> method is implemented using an ioctl call into the file
|
||
system driver with the FIOSYNC command. Most, but not all file system
|
||
drivers support this call. Berkeley DB requires the use of a file system
|
||
that supports FIOSYNC.</p>

|
||
<p>The demo program should be built in a manner very similar to building
|
||
Berkeley DB. If you want different or additional BSP build specifications you
|
||
should add them by following the directions indicated in
|
||
<a class="xref" href="build_vxworks.html#build_vxworks_intro6x" title="Building for VxWorks 6.x">Building for VxWorks 6.x</a>.</p>
|
||
<p>The demo program can be downloaded and run by calling the entry function
|
||
<span class="bold"><strong>dbdemo</strong></span> with the pathname of a database to use. The demo
|
||
program will ask for some input keys. It creates a database and adds
|
||
those keys into the database, using the reverse of the key as the data
|
||
value. When complete you can either enter EOF (control-D) or
|
||
<span class="bold"><strong>quit</strong></span> and the demo program will display all of the key/data
|
||
items in the database.</p>

</div>
|

</div>
|
||
<p>The Berkeley DB utilities can be downloaded and run by calling the function equivalent to the utility's name. The utility functions take a string containing all the supported arguments. The program will then decompose that string into a traditional argc/argv used internally. For example, to execute <a href="../api_reference/C/db_stat.html" class="olink">db_stat</a> utility on a database within an environment you would execute the following from the windsh prompt. Obviously you would change the pathname and database name to reflect
|
||
your system.</p>

||
<pre class="programlisting">> db_stat "-h /tmp/myenvhome -d mydatabase.db"</pre>

<p>The Berkeley DB Replication Manager component is available on Vxworks 6.x because it provides support for TCP/IP sockets and POSIX 1003.1
|
||
style networking and threads. You must build Berkley DB for Vxworks using the command line. Prior to building Berkeley DB, ensure you set appropriate values for the variables
|
||
specified in Step 1 of <a class="xref" href="build_vxworks.html#build_vxworks_intro6x" title="Building for VxWorks 6.x">Building for VxWorks 6.x</a>. To use Berkeley DB Replication Manager, <code class="literal">netLib</code> and <code class="literal">ioLib</code> must be present in the Vxworks image.
