During execution of a critical application process; a system process (e.g db auto shrink) evoked and the process prolonged to manually rollback.
Is DEADLOCK_PRIORITY can be useful against system processes?
We need to disable db auto shrink, but .... any other solution?

not quite sure what you're asking but yes "system" processes can evoke deadlocks - that's why you have to configure your server to avoid such issues. Index rebuilds for instance can also cause deadlocks.
I don't think you can alter the priority for system processes, you could try altering your sessions but I figure that might be risky.

how?
In general I want to get rid of Blocking/Dead locking ultimately, as if a process which may take more than 1 hour for execution and a single sql statement which can trigger out deadlock and would may cause/stop the long running process...!

ah well if it's application then it's processes/code that you need to change - if it's system stuff then you need to find a quiet time. I support real 7 x 24 hour systems so things like index rebuilds are quite painful.
You can set the deadlock priority for your session ith a set command - check it out in BOL. However it doesn't stop deadlocks - just allows you to favour one session over another as the deadlock victim which is why I've never used it to date.
