Enabling the on demand router to work with IBM Enterprise Workload Manager

Use this task to enable IBM® Enterprise Workload Manager™ to monitor Intelligent Management.

Before you begin

To perform this task, you must install IBM Enterprise Workload Manager. See the IBM Enterprise Workload Manager information center for installation instructions.

About this task

By performing this task, the on demand router (ODR) makes Application Response Measurement (ARM) calls to report response times to IBM Enterprise Workload Manager. IBM Enterprise Workload Manager can use the response time information to monitor the environment both inside and outside of the Intelligent Management domain. For more information, read about Intelligent Management and IBM Enterprise Workload Manager.

Procedure

  1. Configure service and transaction classes in IBM Enterprise Workload Manager. The service and transaction classes that you configure in IBM Enterprise Workload Manager override any service classes that are configured in Intelligent Management. See the Enterprise Workload Manager information center for more information.
  2. Configure IBM Enterprise Workload Manager to manage Intelligent Management. After you complete this step, any service policies that are configured in Intelligent Management are not valid. IBM Enterprise Workload Manager has its own configured service and transaction classes.
  3. Copy the ARM libraries from IBM Enterprise Workload Manager to the Intelligent Management configuration. Include the ARM libraries from IBM Enterprise Workload Manager in the install_root/bin directory. Remember the name of this class so that you can supply the information in the administrative console. Alternatively, you can add two custom properties to the application server or ODR Java™ virtual machine (JVM). First, define the java.library.path custom property and set its value to the IBM Enterprise Workload Manager library path, for example c:\Program Files\IBM\VE2\EWLMMS\classes\ms. Next, create the ws.ext.dirs custom property and set its value to the folder that contains the ARM libraries that are provided by IBM Enterprise Workload Manager, for example, c:\Program Files\IBM\VE2\EWLMMS\classes\ARM.
  4. Enable ARM reporting. On the request metrics administrative console page, use the following settings:
    • Select the appropriate application component, such as servlets or Web services, that needs to report ARM statistics.
    • Defining the trace level is optional.
    • Enter the name of the IBM Enterprise Workload Manager ARM factory in the ARM transaction factory implementation class name. The transaction class factory name for IBM Enterprise Workload Manager is com.ibm.wlm.arm40SDK.transaction.Arm40TransactionFactory.
    For more information, read about getting performance data from request metrics.
  5. Enable ARM reporting on your other tiers and applications, such as IBM DB2®, IBM HTTP Server, and also for the various components running on WebSphere® Application Server. You can enable ARM instrumentation in specific WebSphere Application Server components by selecting the appropriate components. For more information, read about getting performance data from request metrics. See the product documentation for your specific tier applications regarding more information on enabling ARM reporting. Any tiers that send requests to the Intelligent Management tier must be ARM enabled to facilitate the interaction between IBM Enterprise Workload Manager and Intelligent Management. Any tiers that receive requests from the Intelligent Management tier do not need to have ARM enabled, however, enabling ARM on these tiers is strongly encouraged.
  6. To enable WebSphere Application Server and Intelligent Management with IBM Enterprise Workload Manager, you must manually update the WebSphere Application Server server.policy files. You must update the server.policy file for all application servers and on demand routers. For more information, read about the server.policy file permission.
  7. Restart all applications and servers that IBM Enterprise Workload Manager is now monitoring.

Results

The on demand routers in the Intelligent Management infrastructure will begin to make ARM calls to report response times on requests. TheIBM Enterprise Workload Manager can monitor the Intelligent Management environment.
