why dtrace is not quiet?
i''m running the following script:
#pragma D option quiet
profile:::tick-1sec
/ ++x >= 15 /
{
exit(0);
}
io:::start {
@io_size[execname] = sum(args[0]->b_bcount);
}
on exit, the script prints out the value of @io_size, why?
there''s no printa(), and i also specified "D option quiet" (i also tried -q).
this seems to happen with any kind of probe: on exit(0) all

invalid probe specifier nge::entry: "/usr/lib/dtrace/procfs.d"
I recently did a backport of a couple of networking bug fixes from s10x_u4_b6 to s10x_u3_b10. I patched just /platform/i86pc/kernel/unix and /platform/i86pc/kernel/amd64/unix in my existing u3 OS image and I''m seeing this dtrace problem when running any dtrace script:
NODE hcb101 ~ $ ./tcpstat.sh

plockstat/dtrace core dump S10U3
Hey,
Im able to reproduce a crash from plockstat everytime Im tracing a JVM pid. I do recall a problem related with this one, but not clear if this has been fixed in U3 or is it planned for U4 ? Any BugID opened for this stack trace:

monitoring tcp writes
i''m using the following probe to calculate how many bytes are being written by tcp write calls, by process and total:

@tcpout_size[execname] = sum(this->tcpout_size);

Analyzing java class loading with dtrace
Hi there,
I am trying to diagnose a performance problem on a Sun T5120 running
Solaris 10. I see general poor performance using Java and, in
particular, loading classes. I have developed a simple java test that
loads all of the classes in a Crystal Reports JAR file (around 7000
classes) which takes much longer on the T5120 (40 secs) than on a Core
2 Duo windows PC (5 secs). I recognise that this

help for a loop procedure
Hello everybody!
I’m trying to define the optimal number of surveys to detect the highest
number of species within a monitoring season/session.
To do this I want to run all the possible combinations between a set of
samples and to calculate the total number of species for each combination of
2, 3, 4 …n samples events, so that at the end I will be able to define which
is the lowest number of

Trouble (?) reformatting flash drive to include former U3 partition
Semi-OT?
I just got a new SanDisk 8GB flash drive, and, as usual, it came with
the U3 software (for Windoze) on a "CD" partition and considerably
less than 8GB on the disk partition. I put it into my WinXP portable
and told U3 to delete itself, but I still can't get at the old U3 part
of the drive. I've tried WinXP's format command, disk management and
CentOS's fdisk,

Replacement in an expression - can't use parse()
Dear all,
Suppose I have a very long expression e. Lets assume, for simplicity, that it is
e = expression(u1+u2+u3)
Now I wish to replace u2 with x and u3 with 1. I.e. the 'new'
expression, after replacement, should be:
> e
expression(u1+x+1)
My question is how to do the replacement?
I have tried using:
> e = parse(text=gsub("u2","x",e))

loop in R
Dear all,
I need to do a loop in R, but I am not sure the software is generating "n" times the variables I request differently. When I ask to print the last matrix created, I just can see the loop for n=1.
To be more precise, supose I need to simulate 10 times one variable and I want to fit the 10 variables simulated in a matrix. I dont really know what I am doing wrong, but I just

Dscript for knowing the I/O processes going on in Solaris10
Hi,
I have an JAVA application using JNI calls which links to native libraries.When i run this application for around 4hrs i am getting a java.io.IOException "Not enough space".
No memory leaks in JAVA as my JProbe reports are fine.
I came across DTrace which help us to know what internally is happening in the Solaris10 machine as I doubt my system configuration for the above

Is there any way to check if DTrace is running or a DTrace probe is enabled?
Hi,
I am adding DTrace probes within NFS v3 client. In my current
implementation, I use some tsd_*() functions and kmem_zalloc() function.
These functions might be heavy and affect the performance. I want to
call this function only when DTrace is running or the DTrace probes are
enable. So is there a way to check DTrace is running or DTrace probe is
enabled?

Kinderman-Ramage (PR#2846)
Hi,
Our department has detected a bug in the implementation of the
Kinderman-Ramage generator for normal random variates in version
1.7.0, which can be seen from the below R session.
(Consecutive calls for chisq.test(...) always gives p-values very
close to 0.)
We have already encountered this bug in version 1.6.2
The error is in file

DTrace unconference?
All,
With Jon Haslam''s exciting news about the DTrace doc wiki (if you haven''t
seen it yet, make your way to http://wikis.sun.com/display/DTrace), and with
some of the discussion with the Apple folks, I''m wondering if the time
isn''t right for something of a DTrace summit, perhaps as an unconference.
The idea here would not be a DTrace user group (though that
