Handling workload management and server failures

Before you begin

During operations, if your application fails repeatedly, causing the application servants to terminate, workload management may terminate the application environment for the application. WebSphere Application Server for z/OS issues the following message if it tries to use a failed application environment:
BBOO0075E Unable to schedule work. WLM application environment applenv has stopped.
You must fix the problem with your application, then restart the application environment with the RESUME option on the VARY WLM command.

Why and when to perform this task

Perform these steps to check and start the workload management application environment.

Note: The dynamic application environment commands apply only if you are running z/OS V1.2 or above with the WLM-DAE support PTF (APAR OW54622). See the assembling applications information in the InfoCenter for more information.

Steps for this task

  1. Display the application environment.
    To do so, issue
    d wlm,applenv=*
    for static application environments or
    d wlm,dynappl=*
    for dynamic application environments.
  2. Start the application environment.
    To do so, issue
    v wlm,applenv=environment_name,resume
    for static application environments (where environment_name is the application environment name) or
    v wlm,dynappl=applenv,resume
    for dynamic application environments.

Results

You know you are done when a re-display of the application environment shows it is available.
