Chapter 4. Process Server ZIP file installation and configuration

You can install Process Server using the file available from the Red Hat Process Automation Manager 7.6.0 Add Ons ( file on the Customer Portal and then configure the Java Database Connectivity (JDBC) web server data sources on Red Hat JBoss Web Server .

4.1. Installing Process Server from ZIP files

Process Server provides the runtime environment for business assets and accesses the data stored in the assets repository (knowledge store). You can use ZIP files to install Process Server on an existing Red Hat JBoss Web Server 5.2.0 server instance.


To use the installer JAR file to install Process Server, see Chapter 3, Using the Red Hat Process Automation Manager installer.

  • The following files have been downloaded, as described in Chapter 2, Downloading the Red Hat Process Automation Manager installation files:

    • Red Hat Process Automation Manager 7.6.0 Add Ons (
    • Red Hat Process Automation Manager 7.6.0 Maven Repository (
  • A backed-up Red Hat JBoss Web Server 5.2.0 server installation is available. The base directory of the Red Hat JBoss Web Server installation is referred to as JWS_HOME.
  • Sufficient user permissions to complete the installation are granted.


  1. Unzip the file.
  2. From the unzipped file, extract the following files:


    In the following instructions, the directory that contains the extracted file is called JWS_TEMP_DIR and the directory that contains the extracted file is called ENGINE_TEMP_DIR.

  3. Copy the JWS_TEMP_DIR/rhpam-7.6.0-kie-server-jws/kie-server.war directory to the JWS_HOME/tomcat/webapps directory.


    Ensure the names of the Red Hat Process Automation Manager deployments you copy do not conflict with your existing deployments in the Red Hat JBoss Web Server instance.

  4. Remove the .war extensions from the kie-server.war folder.
  5. Move the kie-tomcat-integration-7.30.0.Final-redhat-00003.jar file from the ENGINE_TEMP_DIR directory to the JWS_HOME/tomcat/lib directory.
  6. Move the jboss-jacc-api-<VERSION>.jar, slf4j-api-<VERSION>.jar, and slf4j-jdk14-<VERSION>.jar files from the ENGINE_TEMP_DIR/lib directory to the JWS_HOME/tomcat/lib directory, where <VERSION> is the version artifact file name, in the lib directory.
  7. Add the following line to the <host> element in the JWS_HOME/tomcat/conf/server.xml file after the last Valve definition:

    <Valve className="org.kie.integration.tomcat.JACCValve" />
  8. Open the JWS_HOME/tomcat/conf/tomcat-users.xml file in a text editor.
  9. Add users and roles to the JWS_HOME/tomcat/conf/tomcat-users.xml file. In the following example, <ROLE_NAME> is a role supported by Red Hat Process Automation Manager. <USER_NAME> and <USER_PWD> are the user name and password of your choice:

    <role rolename="<ROLE_NAME>"/>
    <user username="<USER_NAME>" password="<USER_PWD>" roles="<ROLE_NAME>"/>

    If a user has more than one role, as shown in the following example, separate the roles with a comma:

    <role rolename="admin"/>
    <role rolename="kie-server"/>
    <user username="rhpamUser" password="user1234" roles="admin,kie-server"/>
  10. Complete one of the following steps in the JWS_HOME/tomcat/bin directory:

    • On Linux or UNIX, create the file with the following content:

      CATALINA_OPTS="-Xmx1024m -Dorg.jboss.logging.provider=jdk"
    • On Windows, add the following content to the setenv.bat file:

      set CATALINA_OPTS=-Xmx1024m -Dorg.jboss.logging.provider=jdk

If you use Microsoft SQL Server, make sure you have configured proper transaction isolation for your database. If you do not, you may experience deadlocks. The recommended configuration is to turn on ALLOW_SNAPSHOT_ISOLATION and READ_COMMITTED_SNAPSHOT by entering the following statements:


4.2. Configuring JDBC Web Server data sources

Java Database Connectivity (JDBC) is an API specification that is used to connect programs written in Java to the data in popular databases. A data source is an object that enables a 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.


  • Red Hat Process Automation Manager is installed on Red Hat JBoss Web Server.
  • The Red Hat Process Automation Manager 7.6.x Maven Repository ( and the Red Hat Process Automation Manager 7.6.x Add-Ons ( files have been downloaded, as described in Chapter 2, Downloading the Red Hat Process Automation Manager installation files.
  • You want to configure one of the following supported databases and Hibernate dialects:

    • DB2: org.hibernate.dialect.DB2Dialect
    • MSSQL: org.hibernate.dialect.SQLServer2012Dialect
    • MySQL: org.hibernate.dialect.MySQL5InnoDBDialect
    • MariaDB: org.hibernate.dialect.MySQL5InnoDBDialect
    • Oracle: org.hibernate.dialect.Oracle10gDialect
    • PostgreSQL: org.hibernate.dialect.PostgreSQL82Dialect
    • PostgreSQL plus: org.hibernate.dialect.PostgresPlusDialect
    • Sybase: org.hibernate.dialect.SybaseASE157Dialect


  1. Complete the following steps to prepare your database:

    1. Extract in a temporary directory, for example TEMP_DIR.
    2. Extract TEMP_DIR/
    3. Change your current directory to the TEMP_DIR/rhpam-7.6.0-migration-tool/ddl-scripts directory. This directory contains DDL scripts for several database types.
    4. Import the DDL script for your database type into the database that you want to use, for example:

      psql jbpm < /ddl-scripts/postgresql/postgresql-jbpm-schema.sql
  2. Extract the offline Maven repository file.
  3. Copy the following libraries from the extracted offline Maven repository to the JWS_HOME/tomcat/lib folder where VERSION is the version of that library:

  4. Copy your database JDBC driver to the JWS_HOME/tomcat/lib folder.
  5. Configure the pooling XA data source in the JWS_HOME/tomcat/conf/context.xml file:


    Some of the properties in the following examples might not apply to your database server. Check the documentation for your JDBC driver to determine which properties to set.

    1. Configure an XA data source without pooling capabilities. This XA data source is used to create new connections to the target database. In the following example, the XA datasource is xads and the variables are defined in Table 4.1, “XA data source variables”:

      <?xml version="1.0" encoding="UTF-8"?>
      description="XA Data Source"
      factory="org.apache.tomcat.jdbc.naming.GenericNamingResourcesFactory" loginTimeout="0"

      Table 4.1. XA data source variables



      The name of the database.


      The port number of the database.


      The name of the database host.


      XADataSource class of JDBC driver.


      The JDBC database connection URL. With some databases, the URL property is url and with other databases (for example H2 databases) this property is URL.


      User name for the database connection.


      Password for the database connection.


      The database schema.

    2. Configure a pooling data source that relies on the XA data source for creating new connections. In this example, the data source is poolingXaDs, <datasource.username> is the user name for the database connection, and <datasource.password> is the password for the database connection:

      <?xml version="1.0" encoding="UTF-8"?>
      description="Pooling XA Data Source" factory="org.jboss.narayana.tomcat.jta.TransactionalDataSourceFactory" testOnBorrow="true"
      transactionManager="TransactionManager" transactionSynchronizationRegistry="TransactionSynchronizationRegistry" type="javax.sql.XADataSource"

      The data source is now available under the java:comp/env/poolingXaDs JNDI name and passes it to the Process Server through the org.kie.server.persistence.ds system property as described in the next steps.


      The pooling data source configuration relies on additional resources that have been previously configured in context.xml file in kie-server application, specifically TransactionManager and TransactionSynchronizationRegistry.

  6. Configure Process Server to use the data source:

    1. Open one of the following scripts in a text editor:


      The or setenv.bat script should already exist. However, if it does not, create it.

      • For Linux or Unix:

      • For Windows:

    2. Add the following properties to CATALINA_OPS where <hibernate.dialect> is the Hibernate dialect for your database:
