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<br>
2. We need to configure a persistence manager in JackRabbit that stores data<br>
in a RDBMS like Oracle<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><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.<br>
5. Is there anything else I'm missing? Will BRMS work fine in the cluster<br>
with the above setup?<br>
<br>
Thanks,<br>
