where -s is the interval between runs and -c the number of times you want to run it. I assume you have interrupted your run before it had been finished so your data is corrupted ?
Anyone ever experienced a core dump when running NMON. I am running AIX 5.3 on an 8 CPU LPAR (P570). This has only recently started to happen. (3 Replies)

I use NMON (Nigels Monitoring) in AIX. It creates a daily nmon log with the naming conventions of:

We have processes that run on our AIX box that sometimes run away and end up consuming 99% of the CPU. I'd like to create a script that would attempt to monitor when this happens and send an email alert with the PID and CPU %. Has anyone done such a thing? I know that you can run the nmon output to...

Hi All,
First of all, I am a DBA and not an AIX admin. I am new at using this NMON tool.
In interactive mode, I can start nmon, push 't' to have the list of process with their statistic (ie cpu% etc.).
I would like to know if there is a way to redirect that screen output into a log... (1 Reply)
Hello,
How can I know if ORACLE Database is running slow due to Memory or due to processing power ?
I have only Oracle Database running on a P4 with 4GB RAM.

io::async::signal
IO::Async::Signal(3pm) User Contributed Perl Documentation IO::Async::Signal(3pm)NAME
"IO::Async::Signal" - event callback on receipt of a POSIX signal
SYNOPSIS
use IO::Async::Signal;
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $signal = IO::Async::Signal->new(
name => "HUP",
on_receipt => sub {
print "I caught SIGHUP
";
},
);
$loop->add( $signal );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a particular POSIX signal is received.
Multiple objects can be added to a "Loop" that all watch for the same signal. The callback functions will all be invoked, in no particular
order.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_receipt
Invoked when the signal is received.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
name => STRING
The name of the signal to watch. This should be a bare name like "TERM". Can only be given at construction time.
on_receipt => CODE
CODE reference for the "on_receipt" event.
Once constructed, the "Signal" will need to be added to the "Loop" before it will work.
