Hi,
I've got some CPU bottleneck on a HP-UX 11 server : i didn't
understand it until i discover i've got an unusual high percentage
of NICE% CPU regarding my DBRMS process (Sybase 12.x).
How do i have to understand it and how to resolve it ?
Thx. (0 Replies)
I've noticed most of my postings here are because of syntax errors.
So I want to begin compiling a large txt file that contains all the "man <cmd>" of the commands I most have problems with. I ran a "man nawk >> nawk.txt" but it included a header/footer on each "page". Anyone know how I'd be... (6 Replies)
Hi I want to implement the nice command in the shell that I am building. I came to know that there is a corresponding nice() system call for the same.

Hi,
I have two identical 12 CPU HPUX machines, and I run the same processes on each that load the boxes fully.
top on one reports activity under the NICE (19%) and SYS (18%) columns, while top on the other reports 0% NICE and 16% SYS. What would cause NICE to be zero on one machine and not... (5 Replies)

Hi All,
I work in a multi user environment where my school uses Red Hat Linux server. When I issue commands such as "top" or "users", I get to see what others are doing and what kinds of applications they are running (even ps -aux will give such information). "users" will let me know who else is... (1 Reply)
Hello Folks,
Recently our FreeBSD 7.1 i386 system became very sluggish.
Nothing much is happening over there & whatever is running takes eternity to complete.
All the troubleshooting hinted towards a very high nice percentage.
Can that be the culprit?
Pasting snippets of top command,... (7 Replies)

serialize
serialize(2) System Calls Manual serialize(2)NAME
serialize() - force target process to run serially with other processes
SYNOPSIS DESCRIPTION
The system call is used to force the target process referenced by the pid value passed in to run serially with other processes also marked
for serialization. If the value of pid is zero, then the currently running process is marked for serialization. Once a process has been
marked by the process stays marked until process completion, unless is reissued on the serialized process with timeshare set to 1. If
timeshare is set to 1, the process specified in pid will be returned to normal timeshare scheduling algorithms.
This call is used to improve process throughput since process throughput usually increases for large processes when they are executed seri-
ally instead of allowing each program to run for only a short period of time. By running large processes one at a time, the system makes
more efficient use of the CPU as well as system memory, since each process does not end up constantly faulting in its working set, to only
have the pages stolen when another process starts running. As long as there is enough memory in the system, processes marked by behave no
differently from other processes in the system. However, once memory becomes tight, processes marked by are run one at a time with the
highest priority processes being run first. Each process runs for a finite interval of time before another serialized process is allowed
to run.
RETURN VALUE
returns zero upon successful completion, or nonzero if the system call failed.
ERRORS
If fails, it sets (see errno(2)) to the following value:
The pid passed in does not exist.
WARNINGS
The user has no way of forcing an execution order on serialized processes.
