start a process with the highest priority

hello,

I have a process lauched by non-root user.

how to lauch this process with a very high priority?

I know this has to do with nice command but how to allow a user to lauch his process with a very high priority and without ROOT intervention?

PS: this process is always lauched from a specific location.

IF your Solaris has sudo, it allows normal users to have extended privileges temporarily.
That may be a solution for you.

thanks we do have sudo.

how to launch a process with a high priority?
thanks
