Chapter 5. Installing Red Hat Decision Manager from ZIP files

Procedure

1. Extract the rhdm-7.8.0-decision-central-eap7-deployable.zip file to a temporary directory. In the following examples this directory is called TEMP_DIR.

2. Copy the contents of the TEMP_DIR/rhdm-7.8.0-decision-central-eap7-deployable/jboss-eap-7.3 directory to EAP_HOME. When prompted, merge or replace files.

   Warning

   Ensure the names of the Red Hat Decision Manager deployments you copy do not conflict with your existing deployments in the Red Hat JBoss EAP instance.

Procedure

1. Extract the rhdm-7.8.0-kie-server-ee8.zip archive to a temporary directory. In the following examples this directory is called TEMP_DIR.

2. Copy the TEMP_DIR/rhdm-7.8.0-kie-server-ee8/kie-server.war directory to EAP_HOME/standalone/deployments/.

   Warning

   Ensure the names of the Red Hat Decision Manager deployments you copy do not conflict with your existing deployments in the Red Hat JBoss EAP instance.

3. Copy the contents of the TEMP_DIR/rhdm-7.8.0-kie-server-ee8/rhdm-7.8.0-kie-server-ee8/SecurityPolicy/ to EAP_HOME/bin. When asked to overwrite files, click Replace.
4. In the EAP_HOME/standalone/deployments/ directory, create an empty file named kie-server.war.dodeploy. This file ensures that KIE Server is automatically deployed when the server starts.

Procedure

1. Complete the following steps to prepare your database:

   1. Extract rhdm-7.8.0-add-ons.zip in a temporary directory, for example TEMP_DIR.
   2. Extract TEMP_DIR/rhdm-7.8.0-migration-tool.zip.
   3. Change your current directory to the TEMP_DIR/rhdm-7.8.0-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

      Note

      If you are using PostgreSQL or Oracle in conjunction with Spring Boot, you must import the respective Spring Boot DDL script, for example /ddl-scripts/oracle/oracle-springboot-jbpm-schema.sql or /ddl-scripts/postgresql/postgresql-springboot-jbpm-schema.sql.

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

3. Add the following properties to the <system-properties> tag where <DATASOURCE> is the JNDI 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>"/>

   The following example shows how to configure a datasource for the PostgreSQL hibernate dialect:

   <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="rhdmUser"/>
       <property name="org.kie.server.pwd" value="rhdm123!"/>
       <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/decision-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>

Procedure

1. In a terminal application, navigate to the EAP_HOME/bin directory.

2. Create a user with the admin, rest-all, and kie-server roles.

   Note

   Users with the admin role are Business Central administrators. Users with rest-all role can access Business Central REST capabilities. Users with the kie-server role can access KIE Server (KIE Server) REST capabilities.

   In the following command, replace <username> and <password> with the user name and password of your choice.

   $ ./add-user.sh -a --user <USERNAME>  --password <PASSWORD> --role admin,rest-all,kie-server

   Note

   Make sure that the specified user name is not the same as an existing user, role, or group. For example, do not create a user with the user name admin.

   The password must have at least eight characters and must contain at least one number and one non-alphanumeric character, but not & (ampersand).

3. Create a user with the kie-server role that you will use to log in to KIE Server.

   $ ./add-user.sh -a --user <USERNAME>  --password <PASSWORD> --role kie-server

4. Make a note of your user names and passwords.

   Note

   If you installed Business Central and KIE Server in the same server instance, you can create a single user that has both of these roles:

   $ ./add-user.sh -a --user <USERNAME>  --password <PASSWORD> --role admin,rest-all,kie-server

   You should install Business Central and KIE Server on different servers in production environments.

Procedure

1. In the Business Central EAP_HOME/standalone/configuration/standalone-full.xml file, uncomment the following properties in the <system-properties> section and replace <USERNAME> and <USER_PWD> with the credentials of a user with the kie-server role:

      <property name="org.kie.server.user" value="<USERNAME>"/>
      <property name="org.kie.server.pwd" value="<USER_PWD>"/>

2. In the KIE Server EAP_HOME/standalone/configuration/standalone-full.xml file, uncomment the following properties in the <system-properties> section.

     <property name="org.kie.server.controller.user" value="<CONTROLLER_USER>"/>
     <property name="org.kie.server.controller.pwd" value="<CONTROLLER_PWD>"/>
     <property name="org.kie.server.id" value="<KIE_SERVER_ID>"/>
     <property name="org.kie.server.location" value="http://<HOST>:<PORT>/kie-server/services/rest/server"/>
     <property name="org.kie.server.controller" value="<CONTROLLER_URL>"/>

3. Replace the following values:

   • Replace <CONTROLLER_USER> and <CONTROLLER_PWD> with the credentials of a user with the rest-all role.
   • Replace <KIE_SERVER_ID> with the ID or name of the KIE Server installation, for example, rhdm-7.8.0-kie-server-1.
   • Replace <HOST> with the ID or name of the KIE Server host, for example, localhost or 192.7.8.9.

   • Replace <PORT> with the port of the KIE Server host, for example, 8080.

     Note

     The org.kie.server.location property specifies the location of KIE Server.

   • Replace <CONTROLLER_URL> with the URL of Business Central. KIE Server connects to this URL during startup.

     • If you installed Business Central using the installer or Red Hat JBoss EAP zip installations, <CONTROLLER_URL> has this format:

       http://<HOST>:<PORT>/decision-central/rest/controller

     • If you are running Business Central using the standalone.jar file, <CONTROLLER_URL> has this format:

       http://<HOST>:<PORT>/rest/controller
