Also, you should probably set the counter by looking at how many MYSQL processes you have running, and not just counting how many have started. This way you automatically have the current number of processes needed.

Hi,
I need to establish a procedure that will start an application in background each time my remote Solaris server is (re)started. This would be a kind of daemon. I am no sysadmin expert, so I am looking for pointers.
How should I proceed? What are the main steps?
Thanks,

Hi,
I'm trying to write a script to decompress a directory full of files. The decompression commands can run in the background, so that many can run at once. But I want to limit the number running at any one time, so that I don't overload the machine.
Something like this:
n=0

pmc.tsc
PMC.TSC(3) BSD Library Functions Manual PMC.TSC(3)NAME
pmc.tsc -- measurements using the i386 timestamp counter
LIBRARY
Performance Counters Library (libpmc, -lpmc)
SYNOPSIS
#include <pmc.h>
DESCRIPTION
In the i386 architecture, the timestamp counter is a monotonically non-decreasing counter that counts processor cycles.
This counter may be selected specifying an event specifier ``tsc'' to pmc_allocate(3). The TSC is a read-only counter that may only be allo-
cated in system-wide counting mode. The ``tsc'' event does not support further event qualifiers.
Multiple processes are allowed to allocate the TSC. Once allocated, the TSC may be read using the pmc_read() function, or by using the RDTSC
instruction.
Event Name Aliases
The alias ``cycles'' maps to the TSC.
