Can dtrace agent of JDK be used in IBM Websphere?(fwd)
------------------forwarded------------------------------------
This is to help my customer to migrate their IBM websphere 6.0.2 to run
on solaris 10 platform.
Customer is eager to use the dtrace agent of JDK
(https://solaris10-dtrace-vm-agents.dev.java.net/ ) to benefit their IBM
websphere server, I am not sure whether we can use this agent in IBM
websphere bundled JDK whose version is JDK

Asterisk vs. Websphere Voice Response?
(Embedded image moved to file: pic18467.gif)
I am a collaboration consultant doing some research for a major client who
has a problem. They have an existing IBM Direct Talk 2 IVR which they were
going to upgrade to the current Websphere product, but choked on the price.
My task is to find out the following:
1. The spec calls for a 24 analog line system with a fairly sophisticated

Invalid address error message
Hi,
I ran a d-program with syscall::open:entry probe but got the following
error messages sometimes:
dtrace: error on enabled probe ID 1 (ID 14: syscall::open:entry): invalid
address (0xff34e000) in predicate at DIF offset 76
dtrace: error on enabled probe ID 6 (ID 14: syscall::open:entry): invalid
address (0xff34e000) in predicate at DIF offset 28
I don''t know how to interpret these

Dtrace Snooping
Dear dtrace Experts,
I have seen some dtrace utilities like opensnoop and execsnoop etc.
My interest is to write a simple script that can snoop the files which
uses the 3 syscalls like open,create,unlink.
I have gone through dtrace oneliners that can do the same :
dtrace -n ''syscall::open*:entry { printf("%s %s",execname,copyinstr(arg0));}''
dtrace -n

copyin having secondary effects.
Dtracing gethostbyname I''m trying to read the h_alias array and all the entries it points to however every time I copyin an entry pointed to by the first entry in teh h_alias array the other entries in the array get corrupted.
So I have ended up with this script:
#!/usr/bin/dtrace -CZs
#include <netdb.h>

strange problem on SXDE3
Strange problem on a desktop, 64 bit, SXDE3.

Doesn''t matter what script. Even classic oneliners such as:

bomb in this way...

Unnamed error while trying to create a VM
Hi,
I''ve a b81 server running for a while. I''ve done all sorts of Python related stuff on it (nothing amazing, mostly compiled python2.5 and iPython in /usr/local), and now am trying to use it with xVM to install Windows on a virtual machine in it.
I''m having trouble creating the new machine, and I get a blank error response like so when I try to do it:

dtrace script to monitor file access
A user has asked us to find out who is changing one of their files and how it is being changed. I came up
with the script below:

#pragma D option quiet

{
printf("\n Timestamp gid uid pid ppid execname function current directory file name\n\n");
}

Triggering on close of a written file.
I have just started my first ''serious'' dtrace script and can use some
advice.
I want to have a probe triggered when close() occurs after a
succesfull write of /etc/hosts ( I want to regenerate the nameserver
zone files
from /etc/hosts after it has changed)
At the moment I have the following code:
syscall::open*:entry,
syscall::creat*:entry

Handling userland char ** pointers
I''ve been trying to get access to a userland string that''s behind a
second level pointer using DTrace, but I can''t seem to get it to work.
I started with the example on the Team DTrace Tips and Tricks slides:
trace(copyinstr(*(uintptr_t *)copyin(arg0, curpsinfo->pr_dmodel ==
PR_MODEL_ILP32 ? 4 : 8)));
And when I couldn''t get it to work, I started

hangs when doing open /pro/pid/psinfo
I got a system that is hung, unable to do most unix commands like ps/who etc...
I did:

''introspect'' method
(PS: another idea that comes along the same lines as a dumper function and IMO would be helpful is an ''introspect'' function. Given an argument:
introspect(probefunc)
it returns back the expected arguments for the probe func, their datastructures, as well as the syntax on how to dereference them. If an intelligent copyinstr comes out, this would be easy to write, and would

How do I print wide char string arguments!
Hopefully this is a straight forward issue and I''m missing
something obvious.
I''m trying to print a wchar_t [] argument from a simple example
program like
#include <stdio.h>
#include <wchar.h>
#include <unistd.h>
void
prout(wchar_t *wstr)
{
}
int
main()
{
wchar_t name[]=L"Angelo Rajadurai";
int i;
for(i=0; i<1000 ; i++)
{

speculative tracing on nevada builds ?
Hi,
Has something related to speculative tracing changed between s10 FCS
and the more recent nevada builds ?
I was trying the specopen.d script from the Dtrace guide on a
nevada machine and it failed with :
dtrace: failed to enable ''./spec.d'': DIF program content is invalid
To try and narrow things down a bit I wrote the following short
script. This works fine on s10, but

Hy!
I receive an nxge driver messages on console:
