Guide for DBIntegration of Oracle 11g

devon4j is by default configured with the H2 Databse.

To integrate devon4j with the Oracle 11g, as a first step , Oracle 11g Database has to be installed . Follow the link to install Oracle 11g.

Installing Oracle JDBC Driver

To install the Oracle JDBC Driver, run the following command

mvn install:install-file -Dfile=C:\app\vkiran\product\11.2.0\dbhome_1\jdbc\lib\ojdbc.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

Note: Location of ojdbc.jar might differ based on the path that is selected at the time of installation of the Oracle 11g.

Enabling Oracle 11g and disabling h2 Database

Assuming the Oracle database that is created is devon4j , execute the following script to create Flyway MetaData Table schema_version in the database devon4j
