Is it possible to place some kind of reservation on a specific dialog work process, so that this process can only be used by a certain specified user ?
not that I know of.
We, too, would like to have a feature like this sometimes.
But not sure if this really is necessary. You may get a lot of info from operating system, even if SAP is hanging.
What comes closest:
If you have got more then one SAP instance, then you may e.g. leave the central instance out from the public logon group, and so dialog processes are left for those who know how to connect without public logon. I am not sure though how you could prevent incoming RFC connections from using these work processes.
indeed, the OS gives us a lot of good information.
However, in problem situations it would often be extremely helpful, if we had a free dialog wp to solve problems quickly without having to restart the whole system.
E.g. there have been more than one occurences, where a malfunctioning subsystem created hundreds of rfc login attempts and each of those tried to run a certain (longrunner) command and blocked a dialog wp.
So if we had have a free wp we simply could've thrown out those rfc users or canceled the processes in use by them within a few seconds. But instead we had to restart the whole system which always took some time under those circumstances ...
I see; one more thought about it:
Do you know about dpmon ?
It is a program at operating system level, and it may be used to cancel work processes. But I am not aware of an OS way how you could throw out users, rfc or others.
Glad it helped; thanks for the star!
And you may be assured, it will work (and auto refresh) even when SAP is hanging.
We often used it to find out e.g. which table accesses are so slow that they will bring down the whole system.
