For your issue I'd suggest using asynchronous servlets. Make your very slow servlet async one, then the original thread is return to the pool for your other servlet and your long running servlet will be run using separate thread.
By default, the exteNd Director portal assigns each asynchronous render request to its own thread in the portlet thread pool. When all threads in the pool have been assigned, incoming asynchronous render requests are delegated to the main request thread, as described in The main request thread.
It depends on the Work request queue size and Work request queue full action, settings. If there are no available threads in the pool, then requests will be queued till the queue size is reached. Then it depends on the action, which might be Block or Fail. would I have any improvement adopting a JMS Queue … 2014-07-26 The ActiveCount statistic on a thread pool in WebSphere is defined as "the number of concurrently active threads" managed by that thread pool. This metric is particularly useful on the WebContainer thread pool because it gives an indication of the number of HTTP requests processed concurrently. 2020-07-21 2021-03-24 2012-10-02 To see a list of the WebSphere Commerce work managers, Open the WebSphere Integrated Solutions Console and expand Resources > Asynchronous beans and click Work Managers. Default thread pool The WebSphere Commerce reserved thread pool enables up to 10 threads by default.
would create. My understanding is Akka requires very few threads to handle large numbers of concurrent actors, but I still need the few threads used to come from the WebSphere Managed Thread pool. Today the CommonJ WorkManager API is used with Spring to use the Managed Thread Pool in WebSphere when asynchronous functionality is needed. After configuring Asynchronous EJB invocations on WebSphere for the last few weeks at work, I had some ideas on how Asynchronous EJBs would work on TomEE and how they can be configured.
In WebSphere Application Server V6.0 and 6.1, Native IO (NIO) and Asynchronous IO (AIO) were introduced, providing the ability to scale to thousands of client connections using a relatively small number of threads. This explains why [you may observe] an average [number of] threads [less than the] concurrent client connection [count]."
You can't lookup threadpools in WebSphere Application Server traditional, note that the Admin Console page for threadpools states "Use this page to specify a thread pool for the server to use", not for your application. You can use a WorkManager to manage concurrent work in your application and you can look up the WorkManager via the JNDI name configured when it was created, see IBM KnowledgeCenter topic Configuring Work Managers. By default, the exteNd Director portal assigns each asynchronous render request to its own thread in the portlet thread pool.
The thread pool size is dependent on your workload and system. In typical configurations, applications need 10 or fewer threads per processor. (Servers > Server Types > Application servers > server_name > Container services > ORB service > Thread pool) Each inbound and outbound request through the ORB requires a thread from the ORB thread pool.
Work managers A work manager is a thread pool created for Java Platform, Enterprise Edition (Java EE) applications that use asynchronous beans. Using the administrative console, an administrator can configure any number of work managers. In WebSphere Application Server traditional, each work manager can be configured with two thread pools. One thread pool is for tasks that are submitted to run as soon as possible (submit/execute/invoke methods of managed executor) and has a configurable work request queue and action to take when the queue capacity is exceeded.
You can monitor performance around asynchronous calls and multithreaded activity in a

2020-07-21 · What is thread-based asynchronous programming. The thread-based asynchronous programming approach, also called “work-stealing” or “bulkheading”, allows one thread pool to hand over a task to another thread pool (let’s call it a work thread pool) and be notified to handle the result when the worker thread pool is done with the task. 2021-02-11 · An application that uses asynchronous scopes should verify that all of the components using scope objects use the same work manager. When multiple work managers are defined, the underlying thread pools are created in a Java virtual machine (JVM) only if an application within that JVM looks up the work manager. Using CountdownEvent to signal when the threads have finished Asynchronous Delegates.
