Step 1: Deploying the Rule Execution Server management archive

Deploy the archive file to use Rule Execution Server on the Liberty profile.

1. Create a Liberty profile server by running the server command from <WLP_HOME>/bin. For example: server create odm
2. Copy the file <InstallDir>/executionserver/applicationservers/WLP855/res.war to <WLP_HOME>/usr/servers/<SERVER_NAME>/apps.
   Note: The .war file supports version 18.0.0.3 of Liberty.
3. Copy the database driver to a directory that you will specify in the server.xml file when you declare the data source. For example, copy the Derby embedded database driver derby.jar from <InstallDir>/shared/tools/derby/lib or from the web to the <WLP_HOME>/usr/shared/resources/derby directory.
4. In <WLP_HOME>/usr/servers/<SERVER_NAME>/server.xml, add the following:
   1. To enable the required features, replace <feature>webProfile-7.0</feature> with:

      <!-- Enable features -->
      <featureManager>
          <feature>servlet-3.1</feature>
          <feature>jsp-2.3</feature>
          <feature>jdbc-4.1</feature>
          <feature>appSecurity-2.0</feature>
          <feature>concurrent-1.0</feature>
      </featureManager>

      Note: You may need to enable the version of these features by running a command such as: <WLP_HOME>/bin/installUtility install servlet-3.1 jsp-2.3 jdbc-4.1 appSecurity-2.0 concurrent-1.0.
   2. To specify the address and port number on which the server listens:

      <httpEndpoint id="defaultHttpEndpoint"
                        host="*"
                        httpPort="9080"
                        httpsPort="9443"/>

   3. To define the data source:

      <!-- RES data source --> 
      <jdbcDriver id="DerbyJdbcDriver" libraryRef="DerbyLib"/>
      <library id="DerbyLib" filesetRef="DerbyFileset"/>
      <fileset id="DerbyFileset" dir="${shared.resource.dir}/derby" includes="derby.jar"/>
      <dataSource id="derbyEmbedded" isolationLevel="TRANSACTION_READ_COMMITTED" jndiName="jdbc/resdatasource" jdbcDriverRef="DerbyJdbcDriver">
          <properties.derby.embedded 
              databaseName="${shared.config.dir}/derby/resdb" 
              createDatabase="create" 
              user="resdbUser" 
              password="resdbUser"
          />
      </dataSource>

      For more information about configuring a data source in the Liberty profile, see the IBM® WebSphere® Application Server Liberty Core documentation
   4. To declare the a default user for each role in the Liberty federated user registry, create users and groups that will bind to the roles:

      <!-- Web application security -->
      <basicRegistry id="basic" realm="customRealm">
          <user name="resAdmin" password="resAdmin"/>
          <user name="resDeploy" password="resDeploy"/>
          <user name="resMonitor" password="resMonitor"/>
          <group name="resAdministrators">
                      <member name="resAdmin"/>
          </group>
          <group name="resDeployers">
                      <member name="resDeploy"/>
          </group>        
          <group name="resMonitors">
                      <member name="resMonitor"/>
          </group>
      </basicRegistry>

   5. To declare the Rule Execution Server console and bind the groups of your user registry to the role:

      <!-- RES console -->
      <application type="war" id="res" name="res" location="${server.config.dir}/apps/res.war">
              <application-bnd>
                  <security-role name="resAdministrators">
                          <group name="resAdministrators"/>
                  </security-role>
                  <security-role name="resDeployers">
                          <group name="resDeployers"/>
                  </security-role>
                  <security-role name="resMonitors">
                          <group name="resMonitors"/>
                  </security-role>
              </application-bnd>
      </application>

5. Save the file.
