ANALYZE/SYSTEM (SDA) can be used to investigate what a process is doing, which may be needed if a process is looping or hanging. If the process uses the threading package, pthread, provided with OpenVMS, it is more difficult to do this. An extension to SDA is provided with recent versions of OpenVMS to help. This document shows how to use that extension to gather the information you need to start investigating.
