Thanks for the prompt reply. It would be surely helpful if you can post the
samples which worked for you. What are the license and support issues that made
you decide against BRMS? My understanding is that we need to enable JackRabbit
clustering when we have JackRabbit running in all nodes of the app server
cluster. Oracle RAD would handle only clustering at the DB level. Please
correct me if I'm wrong.<br>
<br>
Thanks,<br>

We use Drools 4.0.7 in our application which is deployed on a WAS 6.1 cluster<br>
and it is working fine. Now we want to deploy the Drools BRMS also in the<br>
WAS cluster. I went through the Drools and Jackrabbit mailing lists and<br>
documentation. Please confirm if my understanding of how this can be<br>
implemented is correct.<br>
<br>
1. By default, JackRabbit uses Apache Derby in-memory database which does<br>
not support clustering<o:p></o:p></p>
<p><span style='font-size:11.0pt;color:#1F497D'> </span><o:p></o:p></p>
</div>
<p><span style='font-size:11.0pt;color:#1F497D'>That is correct</span><o:p></o:p></p>
<div>
<p><span style='font-size:11.0pt;color:#1F497D'> </span><o:p></o:p></p>
<p><br>
2. We need to configure a persistence manager in JackRabbit that stores data<br>
in a RDBMS like Oracle<o:p></o:p></p>
<p><span style='font-size:11.0pt;color:#1F497D'> </span><o:p></o:p></p>
<p><span style='font-size:11.0pt;color:#1F497D'> </span><o:p></o:p></p>
</div>
<p><span style='font-size:11.0pt;color:#1F497D'>Yes. If you need a sample, I
can send it to you. (Though, I am sure there is a lot of material on this on
the web). </span><o:p></o:p></p>
<div>
<p><br>
3. I need to follow the instructions for JackRabbit clustering given here<br>
<a href="http://wiki.apache.org/jackrabbit/Clustering" target="_blank">http://wiki.apache.org/jackrabbit/Clustering</a><o:p></o:p></p>
<p><span style='font-size:11.0pt;color:#1F497D'> </span><o:p></o:p></p>
</div>
<p><span style='font-size:11.0pt;color:#1F497D'>I am not sure, why you need
Jack Rabbit clustering. If the tables are stored in the database, then I am
assuming RAC should handle clustering at the DB level. Though, do correct
me if I am wrong. </span><o:p></o:p></p>
<div>
<p><span style='font-size:11.0pt;color:#1F497D'> </span><o:p></o:p></p>
<p><br>
4. Also, the Drools documentation says that "The BRMS will create
the<br>
tables the first time it is started up if it is running against a fresh<br>
(empty) RDBMS - so its important to note that the user credentials supplied<br>
have permissions to create tables (at least initially, on first run, after<br>
that they could be locked down)."<br>
Is it not possible to create the Oracle tables before running the BRMS (we<br>
have permission issues in creating the tables from the application)? I<br>
assume that the DDL for creating the tables is available with the JackRabbit<br>
distribution.<o:p></o:p></p>
<p><span style='font-size:11.0pt;color:#1F497D'> </span><o:p></o:p></p>
</div>
<p><span style='font-size:11.0pt;color:#1F497D'>One Q&D way may be to just
create the tables in a test database and then make the schema into DDL scripts
for use before installation. </span><o:p></o:p></p>
<div>
<p><span style='font-size:11.0pt;color:#1F497D'> </span><o:p></o:p></p>
<p><br>
5. Is there anything else I'm missing? Will BRMS work fine in the cluster<br>
with the above setup?<o:p></o:p></p>
<p><span style='font-size:11.0pt;color:#1F497D'> </span><o:p></o:p></p>
</div>
<p><span style='color:#1F497D'>My assumption is that the BRMS is just a web-app
using the database as it's back-end and hence do not know of any issues it
could face. </span><o:p></o:p></p>
