DataStage - Problem when running large parallel jobs on Windows

If you have large parallel jobs (8.1) running in Windows environment then it is worth checking the servers event log. You could find an error related to Nutcracker.exe. An administrator with access right on the server can see the events logs.

Nutcracker error could come up while running very heavy jobs where total cpu utilization is upto or above 90% and server starts using virtual memory. This is just an example of the impact of running large parallel jobs in Windows server. Hence to make the system somewhat full proof following changes can be done in Windows registry. The idea is to tune the TCP/IP buffer, increase the heap size and set the virtual memory to the recommended amount.

I am recommending the Oracle Virtual Box for hosting a guest OS.
