Weblogic server won't start: java.sql.SQLException: [Security:090735]

Question

I've been trying to start the weblogic server, installed locally, but it won't start. In checking the server log I see this as the first Error reported:
java.sql.SQLException: [Security:090735]The DBMS connection was not usable
I changed all ref from localhost to my actual IP and that did not help.
Any ideas what the issue could be?

Answer 1

I did not specify anything reg. a database. It was all created for me by the system, so in checking the config.xml I see something like this:
<jdbc-store>
<name>pfProliferationJMSStore</name>
<prefix-name>PF_PROLIFERATION_</prefix-name>
<data-source>portalDataSourceNeverXA</data-source>
<target>AdminServer</target>
</jdbc-store>
Since I have not created a database, nor created any explicit connections to one, what else could the issue be?
