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>
|
||
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 and VxWorks 7">
|
||
Building for VxWorks 6.x and VxWorks 7</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.

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.

The Berkeley DB Replication Manager component is
|
||
available on Vxworks 6.x and 7 because they provide 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 and VxWorks 7">
|
||
Building for VxWorks 6.x and VxWorks 7</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.
