Hi

I am trying to use Oracle DB as my Node and Document storage for AEM instead of the JCR.

I understand there is no full support for this implementation from Adobe.

I am referring the below Adobe Doc : RDBMS Support in AEM 6.3

I have done the below steps :

  1. Downloaded Oracle JDBC Jar "ojdbc8.jar" and converted this jar into an OSGi bundle named "com.oracle.jdbc_1.0.1.jar". I had resolved all dependencies and the bundle installs in Active State
  2. I created two config files under "crx-quickstart\install".
    • org.apache.jackrabbit.oak.plugins.document.DocumentNodeStoreService.config
      • documentStoreType="rdb"

      • dataSource="oak"

      • persistentCache="-"

      • journalCache="-"

    • org.apache.sling.datasource.DataSourceFactory-oak.config
      • datasource.name="oak"

      • url="jdbc:oracle:thin:@//localhost:1521/ORCLCDB"

      • driverClassName="oracle.jdbc.OracleDriver"

      • username="sys"

      • password="WelcomeAEM!"

      • testOnConnect="false"

      • testWhileIdle="false"

      • dataSourceJNDI="jdbc/OAK"

  3. I placed the JDBC OSGi bundle "com.oracle.jdbc_1.0.1.jar" under "crx-quickstart\install\9".
  4. I started the AEM Server with "java -jar cq-author-p4502.jar -r crx3,crx3rdb"

I am getting "Oracle Driver not found error" as below.

Appreciate your help. I think I am missing something fundamental.

Check if you have added right dependency for Oracle/RDBMS Drivers  and its running the bundle?

Hi Navin, Yes, the dependencies are right and the bundle is running.

Hi,

Make sure your bundle that you created for oracle declares that it exports oracle.jdbc.OracleDriver in it's OSGi export declaration.

E.g. it tells everyone that they may use code from oracle.jdbc.

Regards,

Peter

Do you mean you want to replace all of the JCR with a relational database? In our relational database articles - we stored app data there (ie - customer records) - not replace the JCR.

Talk to Adobe Support whom replied:

There is RDBMK that support Oracle DB, but this is for Forms only.

For AEM with no Forms it’s not supported

According to [1] the support level is "restricted". Which means you should get in contact with Adobe Support first. The only limiation to "Forms only" applies to Microsoft SQL Server, but not to DB2.

We are using AEM 6.3 Forms and are trying to setup a server cluster with RDBMK (Oracle 12c) as the repository type.  For testing purposes, we attempted a single standalone install with a rdb as the repository type first. After saving changes to the Apache Sling Connection Pooled Datasource configuration, we get the exception "Unable to create initial connections of pool".  Please see below.
