Setting user priorities

Hi folks,

Is it possible to set up a Linux installation to have specific priorities for individual users. For example, all jobs submitted by dsadm will have higher priority by default than those submitted by fbloggs?

I know about nice/renice, but those rely on entering manual commands (and on knowing PIDs) - what I was after was something a bit more automated..

Many thanks,
S

What you can do depends upon your version of UNIX. On some LINUX systems you can use the method described at nice & renice. I would think that for other UNIX implementations one could find appropriate scripts that would do this, at worst a simple script running with admin rights could do this as well.

Within TCL the CHAP (CHAnge Priority) command can be used to lower priority. Usage is CHAP DOWN.

Or you could put a renice command into dsenv controlled by a test on user ID. Process ID and user ID are available from shell veriables $$ and $USER respectively.

Thanks both for the pointers.
