I currently have a tomcat 6 setup, and I am trying to understand how it handles the threadpools.
I have an executor defined, and I have an AJP connector that uses it.
I have specified a minSpareThreads in the executor, but when I look at the thread pool info in psi-Probe it does not seem to be behaving as I expect it to.
I know that in tomcat5, you could specify a minSpareThreads and a maxSpareThreads and then tomcat would start minSpareThreads and create up to maxThreads as needed, then keep the number of spare, idle threads somewhere between minSpareThreads and maxSpareThreads.
I also know that in tomcat6, this functionality was moved to executors and the maxSpareThreads attribute was removed.
I have minSpareThreads set to 30, but when I watch the server in psi-Probe I see that the current number of threads is usually equal to the number of busy threads or 2-3 higher, and often drops down to 2-3 total when the server is idle.
Am I missing some config option, or is my understanding of how this should work flawed?
Thank you for your assistance in this.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
