Case Study: Hang Conclusion
This is pretty obviously an application problem. Two programs are locking datasets in a
database in the opposite order.
It is also very likely that some far less drastic measure could have been taken to diagnose
this short of taking the system down and dumping it.
Unfortunately most system hang’s are not as easy and obvious as this one was to
diagnose. Any information that can be gather beforehand will help.
