Number of threads in use

An application might require a large number of threads. Each queue manager process is allocated a maximum allowable number of threads.

If some applications are troublesome, it could be due to their design using too many threads. Consider whether the application takes into account this possibility and that it takes actions either to stop or to report this type of occurrence.

The maximum number of threads that OS/400 allows is 4095. However, the default is 64. WebSphere MQ makes available up to 63 threads to its processes.
