Setting Up Liferay 7.4 CE with MariaDB and Connector to External Oracle DBSetting Up Liferay 7.4 CE with MariaDB and Connector to External Oracle DBhttps://liferay.dev/c/message_boards/find_thread?p_l_id=119785294&threadId=1223682512026-04-06T02:08:36Z2026-04-06T02:08:36ZRE: Setting Up Liferay 7.4 CE with MariaDB and Connector to External Oracle DBOlaf Kockhttps://liferay.dev/c/message_boards/find_message?p_l_id=119785294&messageId=1223695112024-01-30T11:22:17Z2024-01-30T11:22:16Z<p>To me, it would be infinitely more helpful if you mentioned what you
specifically have done, and what the message was.</p>
<p>Right now, you're listing a lot of resources, that would take me a
couple of hours to follow - and then I might do something differently
than you and succeed, which would give neither of us some insight.</p>
<p>Ideally, please provide a (minimal) code example, that clarifies what
you're trying to do - e.g. are you trying to connect ServiceBuilder to
a secondary datasource? (likely: Won't work within CE, unless you
specifically install custom Oracle Support)</p>Olaf Kock2024-01-30T11:22:16ZSetting Up Liferay 7.4 CE with MariaDB and Connector to External Oracle DBJonathan Tranhttps://liferay.dev/c/message_boards/find_message?p_l_id=119785294&messageId=1223682502024-01-30T11:08:37Z2024-01-29T17:56:06Z<p>Hi All,</p>
<p>We have been struggling for a couple weeks trying to set up Liferay
7.4 CE with a default connection into MariaDB and a secondary external
connection into Oracle DB. We have exhausted our the resources
provided to us and are in need of some direction. Some of the
resources include:</p>

</ul>
<p>We have gotten to the point where we have completed the context
switching as we are using the tomcat context and server xmls to
provide our connection strings. However, we are running into a wall
when trying to connect as we get the following error: <strong>Cannot
load JDBC driver class 'oracle.jdbc.OracleDriver'
java.lang.ClassNotFoundException: oracle.jdbc.OracleDriver cannot be found</strong>
</p>
<p>The ojdbc8.jar file is located in the shielded-container-lib as well.<br>
<br> Please advise.<br>
<br> Version of Liferay: <strong>liferay-ce-portal-7.4.3.100-ga100</strong>
