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)

wakeup
wakeup(9r)wakeup(9r)NAME
wakeup - General: Wakes up all processes sleeping on a specified address
SYNOPSIS
void wakeup(
caddr_t channel );
ARGUMENTS
Specifies the address on which the wakeup is to be issued.
DESCRIPTION
The wakeup routine wakes up all processes sleeping on the address specified by the channel argument. All processes sleeping on this address
are awakened and made ready to be scheduled according to the priorities they specified when they went to sleep. It is possible that there
are no processes sleeping on the channel at the time the wakeup is issued. This situation can occur for a variety of reasons and does not
represent an error condition.
The sleep and wakeup routines block and unblock a process. Generally, a device driver issues these routines on behalf of a process request-
ing I/O while a transfer is in progress. That is, a process requesting I/O is put to sleep on an address associated with the request by the
appropriate device driver routine. When the transfer has asynchronously completed, the device driver interrupt service routine issues a
wakeup on the address associated with the completed request. This action makes the relevant process to be scheduled.
The process resumes execution within the relevant device driver routine at the point immediately following the request to sleep. The
driver, on behalf of the process, can then determine whether the condition for which it was sleeping (in this example, completion of an I/O
request) has been removed. If so, it can continue on to complete the I/O request. Otherwise, the appropriate driver routine can decide to
put the process back to sleep to await removal of the indicated condition.
RETURN VALUES
None
