Hi, I have have a couple of questions about "at" and "batch" under IRIX 3.1 (on a 4D/20G). From reading the man page and looking at the configuration files, it seems there exists the possibility to configure the at control system at two different points. One is using the /usr/lib/cron/queuedefs file, mine looks like this: a.4j1n b.2j2n90w From the short description in the man page the letter stands for the queue, and the stuff following the the point is the configuration of that queue. Unfortunately there is no documentation (that I can find) on what the symbols mean, or anything. Can someone point me to some documentation on that subject? Similarly the file /usr/lib/cron/.proto file has some variables in it that appear to allow specific configuration of each job. The file is much in the same style as one might use for configuring rn ($d == directory, $l == ulimit, etc). Is there any documentation for these variables? +++ My second question has to do with system load. Once again the man page for batch suggests that system load is taken into account when scheduling jobs, I would be interested in knowing how is this done. I would also like to be able to determine the load on the machine, but not using "sa." Is there a kernel variable/location that can be located (via. nlist) and then read?
