"Session has become invalid" message received

You try to use the Dynamic Workload Console user interface, your working session closes, and you get the following warning:

Session has become invalid 
Your session has become invalid. This is due to a session timeout, an administrator 
has logged you out, or another user has invalidated your session by logging on with 
the same User ID.

Cause and solution:

Check which reason among those listed in the warning has occurred, solve the issue, and then log in again to continue your working session.

If the session expired because either the HTTP session or the Lightweight Third Party Authentication (LTPA) session timeout was exceeded, you might decide to customize the timeout settings to values that are appropriate for your environment.

For instructions on how to do this, see the topic on session timeout settings in the Performance chapter of the IBM® Workload Scheduler: Administration Guide.
