This is in a sense OT as it deals with a DOS/Windows scheduling issue.
However, it arises from a Java application so I feel that it might be a
good place to post my question. It might be that some of you has seen
this problem.

In order to run a SAS job from a Java program, we are using a simple
runtime.getruntime.exec({"C:/Program
Files/sas.exe","myloc/myfile.sas"}).
That works great, but my boss wants to have it run with a set lower
priority so that it doesn't interrupt other tasks on the server. How do
I do that?

Thanks in advance.

Your example has bad capitalization and will not compile. However...

I have not tried this, but I am going to guess that the solution involves the
"start" command. If you have Windows XP, you might try:

Runtime.getRuntime.exec({"C:/WINDOWS/system32/cmd.exe", "/C", "START",
"/BELOWNORMAL", "C:\\Program Files\\sas.exe", "myloc/myfile.sas"}) ;


I have turned some forward slashes into double backslashes. Backslashes are
needed to meet the expectations of the START command, and doubling is
required for Java strings.

I don't have the right environment to try this, but perhaps it is close
enough to give someone an idea. Perhaps there is an easier way.

Good luck!

Sounds reasonable, although I would suggest wrapping the whole thing in
a BAT file, to separate the "priority" of the running app from the
concern of the runner app.

Even better than my solution. I like it!
