Oracle for CrowdID

Follow the steps below to connect CrowdID to Oracle.

1. Configure Oracle

Create a database user which CrowdID will connect as (e.g. crowduser).
Create a database for CrowdID to store data in (e.g. crowdiddb). This must be a different database to the one used by Crowd.
Ensure that the user has permission to connect to the database, and create and populate tables.

2. Copy the Oracle driver to your application server

Download the Oracle JDBC driver from http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html.
Add the Oracle JDBC driver jar to the common/lib directory.

3. Configure your application server to connect to Oracle

Edit the file apache-tomcat-X.X.XX/conf/Catalina/localhost/openidserver.xml and customise the username, password, driverClassName and url parameters for the Datasource.

<Context path="/openidserver" docBase="../../crowd-openidserver-webapp" debug="0">

    <Resource name="jdbc/CrowdIDDS" auth="Container" type="javax.sql.DataSource"
              username="[enter db username here]"
              password="[enter db password here]"
              driverClassName="oracle.jdbc.driver.OracleDriver"
              url="jdbc:oracle:thin:@localhost:1521:crowdiddb"
              [ delete the minEvictableIdleTimeMillis, timeBetweenEvictionRunsMillis and maxActive params here ]
            />

    <Manager className="org.apache.catalina.session.PersistentManager" saveOnRestart="false"/>

</Context>

Delete the minEvictableIdleTimeMillis, timeBetweenEvictionRunsMillis and maxActive attributes (which are only needed for HSQL, and degrade performance otherwise).

4. Configure CrowdID to use Oracle

Edit the build.properties file (located in the root of the standalone release) and modify the hibernate.dialect to the following
```
hibernate.dialect=org.hibernate.dialect.OracleDialect
```
Then run ./build.sh or build.bat. This will configure CrowdID to use the Oracle dialect. There is a problem with build.bat in Crowd version 1.2.0. To fix the problem, please apply the patch described in CWD-638.

If you do not wish to edit this file and run the build script, you can edit the jdbc.properties (which the above script modifies) directly. The jdbc.properties file is located here: crowd-openidserver-webapp\WEB-INF\classes\jdbc.properties. Modify the file to the following:

# - Crowd Configuration Options

hibernate.connection.datasource=java\:comp/env/jdbc/CrowdIDDS
hibernate.dialect=org.hibernate.dialect.Oracle
hibernate.transaction.factory_class=org.hibernate.transaction.JDBCTransactionFactory

...

Next Steps

You should now have an application server configured to connect to a database, and CrowdID configured to use the correct database. Now start up CrowdID and watch the logs for any errors.
