Title: How to Configure NO Timeout for WCC session?
Description:
Configuring Session Time-out for WCC components / application; it requires User Authentication each time the application stays idle for over 30 minutes by default.
Solution:
To modify the session time-out for a CA WCC component, you must modify the time-out value of the underlying Apache Tomcat server.
Open the web.xml file, located in the following folder, using a text editor:
WCC_installation_root\servername\conf\
The following XML element appears, containing the Session Timeout value, which is 30 minutes by default:
<session-config>
<session-timeout>30</session-timeout>
</session-config>
Change the value from 30 to the appropriate value (in minutes).
Save and close the web.xml file.
Restart the appropriate service. For example, restart CA WCC Configuration Server.
#Session timeout for individual application can be configured; Session time-outs for all applications are determined by the <session-timeout> parameter in each Tomcat Application Server's web.xml file.
Example:
C:\Program Files\CA\Workload Control Center\ConfigServer\conf
C:\Program Files\CA\Workload Control Center\QuickEditServer\conf
C:\Program Files\CA\Workload Control Center\QuickViewServer\conf
C:\Program Files\CA\Workload Control Center\JobStatusConsoleServant\conf
