Chapter 5. Configuring JDBC data sources for Process Server

A data source is an object that enables a Java Database Connectivity (JDBC) client, such as an application server, to establish a connection with a database. Applications look up the data source on the Java Naming and Directory Interface (JNDI) tree or in the local application context and request a database connection to retrieve data. You must configure data sources for Process Server to ensure proper data exchange between the servers and the designated database.

Prerequisite

The JDBC providers that you want to use to create database connections are configured on all servers on which you want to deploy Process Server.

Procedure

  1. Open EAP_HOME/standalone/configuration/standalone-full.xml in a text editor and locate the <system-properties> tag.

  2. Add the following properties to the <system-properties> tag where <DATASOURCE> is the name of your data source and <HIBERNATE_DIALECT> is the hibernate dialect for your database.

    Note

    The default value of the org.kie.server.persistence.ds property is java:jboss/datasources/ExampleDS. The default value of the org.kie.server.persistence.dialect property is org.hibernate.dialect.H2Dialect. 

    <property name="org.kie.server.persistence.ds" value="<DATASOURCE>"/>
<property name="org.kie.server.persistence.dialect" value="<HIBERNATE_DIALECT>"/>

    For example: 

    <system-properties>
    <property name="org.kie.server.repo" value="${jboss.server.data.dir}"/>
    <property name="org.kie.example" value="true"/>
    <property name="org.jbpm.designer.perspective" value="full"/>
    <property name="designerdataobjects" value="false"/>
    <property name="org.kie.server.user" value="rhpamUser"/>
    <property name="org.kie.server.pwd" value="rhpam123!"/>
    <property name="org.kie.server.location" value="http://localhost:8080/kie-server/services/rest/server"/>
    <property name="org.kie.server.controller" value="http://localhost:8080/business-central/rest/controller"/>
    <property name="org.kie.server.controller.user" value="kieserver"/>
    <property name="org.kie.server.controller.pwd" value="kieserver1!"/>
    <property name="org.kie.server.id" value="local-server-123"/>

    <!-- Data source properties. -->
    <property name="org.kie.server.persistence.ds" value="java:jboss/datasources/KieServerDS"/>
    <property name="org.kie.server.persistence.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
</system-properties>
