1.3.5.5.3.2 Configuring Deployment Descriptor for PGQL on RDBMS

To configure the Graph Visualization application to communicate with Oracle Database (PGQL on RDBMS):

1. Edit the value for the graphviz.driver.class context parameter as shown:

   <context-param>
   	<param-name>graphviz.driver.class</param-name>
   	<param-value>oracle.pg.rdbms.PgqlDriver</param-value>
   </context-param>

2. Set the context parameter graphviz.driver.rdbms.jdbc_url referencing the JDBC URL of your Oracle Database:

   <context-param>
   	<param-name>graphviz.driver.rdbms.jdbc_url</param-name>
   	<param-value>jdbc:oracle:thin:@myhost:1521/myService</param-value>
   </context-param>

   Note:

   Replace the URL in the example with the JDBC URL that you want to use for user authentication.

   When the Graph Visualization application is using PGQL on RDBMS, the application displays a custom login page and the user can use their Oracle Database credentials for user authentication, using the Oracle Database set mentioned in this step. After logging in, you can see the graphs that you are granted to see on the Oracle Database.
