Now that your database is deployed the final step is to configure Apache.

==== /etc/sysconfig/httpd - Oracle configuration ====
 +
 +
The Oracle environment must be set correctly before starting Apache so that PHP OCI8 works correctly. In general you should set the same variables that are set by the ''$ORACLE_HOME/bin/oracle_env.sh'' script. The necessary environment variables can be set in Apache's environment configuration file.
 +
On RedHat Linux and its derivatives with the default httpd package, this is ''/etc/sysconfig/httpd''.
 +
<pre>
 +
export ORACLE_HOME=/u01/app/oracle/product/12.1    # Adjust pathname to match your installation

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH

This shows the process of creating an entity, using its get and set methods to enter and retrieve data and then committing it to the database. It also shows the process of using the PDO connection to check that the data exists in the database as we expect.
