How to create a Stuck Thread in order to test your weblogic settings? Put a breakpoint in a backing bean or model method that is called with you request. Work Managers have a Ignore Stuck Thread options that gives the ability to execute long running jobs.

Tools to help you with analyzing the Thread Dumps can be:Īfter you have identify the code that causes the Stuck Thread, that is the code which execution takes more than the Stack Thread Max Time, you can use Work Manager to execute your code. Check Sending Email Alert For Stuck Threads With Thread Dumps post of Middleware magic, to have Thread Dumps mailed to you automatically when they occur. The most recommended way is to check the thread dumps. In a cluster, clustered clients that are connected or attempting to connect will fail over to another cluster member. Mark the server instance as failed and shut it down it down if there are stuck threads in the server.All Work Managers belonging to the application are shut down, and behave as described above. The application is shutdown by bringing it into admin mode. Shut down the application if there are stuck threads in the application.In a cluster, clustered clients will fail over to another cluster member. A Work Manager that is shut down will refuse new work and reject existing work in the queue by sending a rejection message. If all application threads are stuck, a server instance marks itself failed, if configured to do so, exits. You can configure Node Manager or a third-party high-availability solution to restart the server instance for automatic failure recovery.You can configure these actions to occur when not all threads are stuck, but the number of stuck threads have exceeded a configured threshold:Shut down the Work Manager if it has stuck threads. WebLogic Server checks for stuck threads periodically (this is the Stuck Thread Timer Interval and you can adjust it here). What you can do to avoid your application completely fail? Usually, the number of stuck threads will increase and your server will eventually crash. So practically, a couple of Stuck Threads might not crash your server preventing it from serving request, but it is a bad sign. If all threads in, , or a user-defined execute queue become stuck, the server changes its health state to " warning.".For more information, see " Node Manager Capabilities" in Configuring and Managing WebLogic Server.) If all threads in the default queue become stuck, the server changes its health state to " critical." (You can set up the Node Manager application to automatically shut down and restart servers in the critical health state.If all threads in an execute queue become stuck, the server changes its health state to either "warning" or "critical" depending on the execute queue: WebLogic Server automatically detects when a thread in an execute queue becomes "stuck." Because a stuck thread cannot complete its current work or accept new work, the server logs a message each time it diagnoses a stuck thread.
