<p>
To configure the Tuxedo system to use Berkeley DB resource
managers, do the following:
</p>
<div class="sect2" lang="en" xml:lang="en">
<div class="titlepage">
<div>
<div>
<h3 class="title"><a id="idm140654536835360"></a>Update the Resource Manager File in Tuxedo</h3>
</div>
</div>
</div>
<p>
For the purposes of this discussion, assume that the
Tuxedo home directory is in
</p>
<pre class="programlisting">/home/tuxedo</pre>
<p>
In that case, the resource manager file will be located
in
</p>
<pre class="programlisting">/home/tuxedo/udataobj/RM</pre>
<p>
Edit the resource manager file to identify the Berkeley
DB resource manager, the name of the resource manager
switch, and the name of the library for the resource
manager.
</p>
<p>
For example, on a RedHat Linux Enterprise (64-bit)
installation of Oracle Tuxedo 11gR1, you can update the
resource manager file by adding the following line:
</p>
<pre class="programlisting">BERKELEY-DB:db_xa_switch:-L${DB_INSTALL}/lib -ldb </pre>
<p>
where <code class="literal">${DB_INSTALL}</code> is the directory
into which you installed the Berkeley DB library.
</p>
<p>
Note that the load options may differ depending on the
platform of your system.
</p>
</div>
<div class="sect2" lang="en" xml:lang="en">
<div class="titlepage">
<div>
<div>
<h3 class="title"><a id="idm140654536788496"></a>Build the Transaction Manager Server</h3>
</div>
</div>
</div>
<p>
To do this, use the Tuxedo <span class="bold"><strong>
buildtms(1) </strong></span> utility. The <span class="bold"><strong>buildtms</strong></span> command will create
the <code class="literal">Berkeley-DB</code> resource manager in the
directory from which it was run. The parameters to the
<span class="bold"><strong>buildtms</strong></span> command
should be:
</p>
<pre class="programlisting">buildtms -v -o DBRM -r BERKELEY-DB</pre>
<p>
This will create an executable transaction manager
server, <code class="literal">DBRM</code>, which is called by Tuxedo
to process begins, commits, and aborts.
</p>
</div>
<div class="sect2" lang="en" xml:lang="en">
<div class="titlepage">
<div>
<div>
<h3 class="title"><a id="idm140654536869072"></a>Update the UBBCONFIG File</h3>
</div>
</div>
</div>
<p>
You must make sure that your TUXCONFIG environment
variable identifies an UBBCONFIG file that properly
identifies your resource managers. In the GROUPS section
of the UBBCONFIG file, you should identify the group's
LMID and GRPNO, as well as the transaction manager server
name "TMSNAME=DBRM." You must also specify the OPENINFO
parameter, setting it equal to the string
</p>
<pre class="programlisting">rm_name:dir</pre>
<p>
where rm_name is the resource name specified in the RM
file (that is, BERKELEY-DB) and dir is the directory for
the Berkeley DB home environment (see <a href="../api_reference/C/envopen.html" class="olink">DB_ENV->open()</a> for a
discussion of Berkeley DB environments).
</p>
<p>
Because Tuxedo resource manager startup accepts only a
single string for configuration, any environment
customization that might have been done via the config
parameter to <a href="../api_reference/C/envopen.html" class="olink">DB_ENV->open()</a> must instead be done by placing a
<a class="xref" href="env_db_config.html" title="DB_CONFIG configuration file">DB_CONFIG configuration
file</a> in the Berkeley DB
environment directory. See <a class="xref" href="env_naming.html" title="File naming">File naming</a> for further information.
</p>
<p>
Consider the following configuration. We have built a
transaction manager server, as described previously. We
want the Berkeley DB environment to be
<code class="literal">/home/dbhome</code>, our database files to
be maintained in <code class="literal">/home/datafiles</code>, our
log files to be maintained in
<code class="literal">/home/log</code>, and we want a duplexed
server.
</p>
<p>
The GROUPS section of the ubb file might look like the
following:
</p>
<pre class="programlisting">group_tm LMID=myname GRPNO=1 TMSNAME=DBRM TMSCOUNT=2 \
OPENINFO="BERKELEY-DB:/home/dbhome"</pre>
<p>
There would be a <a class="xref" href="env_db_config.html" title="DB_CONFIG configuration file">DB_CONFIG configuration
file</a> in the directory
<code class="literal">/home/dbhome</code> that contained the
following two lines:
</p>
<pre class="programlisting">add_data_dir /home/datafiles
set_lg_dir /home/log</pre>
<p>
Finally, the UBBCONFIG file must be translated into a
binary version using Tuxedo's <span class="bold"><strong>tmloadcf </strong></span>(1)
utility, and then the
pathname of that binary file must be specified as your
TUXCONFIG environment variable.
</p>
</div>
<p>
At this point, your system is properly initialized to use
the Berkeley DB resource manager.
</p>

files using XA.
