Dtrace on Solaris 2.6 -- ?

I know the very notion is ridiculous. Or is it? Can someone confirm with authority that dtrace will not run on Solaris 2.6?
I'm trying to rule out options in resolving some issues we're having on a legacy app.
Thanks...

Even though the app is legacy, is there any chance you can run it on Solaris 10? Maybe you can do some debugging there and bring that knowledge back to the production instance on Solaris 2.6.
Long shot, but can work in some cases.

Dtrace for Solaris 9

Hello,
As I understand Dtrace is available from Solaris 10.
Is there any patch/package for Solaris 9 version?
Please let me know the details if available.
Please let me know if any other tool which is similar to that of Dtrace which is available for Solaris9.
Thanks,
Vinay

Please let me know the details if available.No, it's not.
Besides the actual dtrace executable, thousands of probes were placed into the kernel. Backporting that to earlier systems would be very expensive. It's not going to happen.
Please let me know if any other tool which is similar to that of Dtrace which is available for Solaris9.Nope.
For process (and some library) tracing you have 'truss'. For some I/O visibility you have kernel tracing with prex/tnfdump/tnfextract. None of those have similar power to dtrace.

DTrace probes for oracle database 10g in solaris 10

Hi guys,since a mounth i`ve learnt about solaris DTrace and its D scripts and tried to look for probes for administrating oracle database but til now,nothing!so my question,does there DTrace probes for oracle application ?i really need it now,that`s my project:tracing oracle with DTrace in solaris 10 SPARC!anyone can help me pleaaase!!!

Hey!!of course that's a great site but U know,i've already visit it and it doesn't talk about probes for oracle!!howeiver i thought about another option,how do u think about exploiting oracle instance...i mean,do u think it's possible to monitoring oracle processes (LWGR,PMON,DBWR,SMON,...) with DTrace by using providers?like fbt or io,i don't know much!!remember,the aim is monitoring oracle database performance !!
regards!

It seems hard for the press to define DTrace

I've just read this on http://www.zdnet.com.au/news/software/0,2000061733,39159307,00.htm:
"major new enhancements in the operating system , including ... a dynamic tracing feature, called DTrace, for automatically diagnosing common problems."
While it is a major new enhancement, I don't think you could say it automatically diagnoses common problems. It seems that DTrace is not an easy to grasp concept. I also think ZFS will not be easy to get at first, as well.
Hopefully, in time, examples and blueprints like articles will finally make all Solaris 10 great enhancements well understood by everyone.
Vlad.

I am a beginner to solaris , can any one help me
understand what DTrace is, i would be grateful if u
couls provide me the links to understand it better.Start by reading the DTrace Guide at http://docs.sun.com/app/docs/doc/817-6223
Check other messages in this forum, maybe "What is DTrace? in a nutshell?" for a very short description.
Or, to quickly see some of what it can do for you (to motivate you to learn it ) run some scripts you can find in the Dtrace Guide, in this forum or at http://www.brendangregg.com/dtrace.html
currently i have 0 knowledge on DTrace and Solaris 10.Useful links for Solaris 10:
-> docs.sun.com - very well organized documentation sets
-> www.sun.com/bigadmin - articles, links and "recipes"
-> comp.unix.solaris (easily accessible through groups.google.com) - active forum with a lot of useful information
-> solarisx86 Yahoo group for (but not restricted to) Solaris on x86 issues
Good luck,
Vlad.

Installation of the Thread Scheduling Visualizer (TSV)

Hi,
I've already written some realtime applications and now I want to monitor them via TSV. I've downloaded RTS 2.1 with TSV and installed RTS 2.1. I guess TSV isn't installed yet (command "drecord" is not known by solaris). So I think TSV is inside the file "threadsc.gz", isn't it? I've already extracted this file, but still I don't know, how to install TSV.
I've already read the TSV Guide, but there are only very poor informations on the installation of it.
So can anyone explain to me, what the name of the TSV installation file is and how I can install it on Solaris?
Thanks a lot!

Hi Gordon:
TSV can be downloaded when you download the Java RTS 2.1 eval on
Solaris; just to be clear, TSV is based on DTrace (a Solaris specific
tool), hence it's not available for Linux. When you go through the Java
RTS 2,1 eval download process for Solaris (either x86 or SPARC version),
you will see the TSV download link listed on the final page (after having
taken the survey and agreeing with the eval license) -- it's the same
page as the one that also lists the Java RTS 2.1 eval download link.
The name of the TSV bundle on that page is "tsv-1.2.tar.gz". All you
need to do to install this is to unpack it.
HTH,

DTrace support for 64 bit JDK on Solaris 10

Hi,
I installed latest 64 bit jdk 1.6_23, using self-extract file, on solaris 10 machine,
and I can't find the hotspot provider for dtrace when I use 64 bit jvm,
I can find them when I use 32 bit,
I use the following command:
$ dtrace -ln 'hotspot*:::'
When I run java -server TestGreeting, ( This program just does endless loop, I borrowed from internet)
I got the probes
When I run with java -d64 -server TestGreeting
I got the following error:
-bash-3.00$ dtrace -ln 'hotspot*:::'
ID PROVIDER MODULE FUNCTION NAME
dtrace: failed to match hotspot*:::: No probe matches description
and when I use ps -ef to grep the java, it shows
~/jdk1.6.0_23/bin/amd64/java -server TestGreeting
Does dtrace support 64 bit JVM?
Thanks

Use 32bit for client VM. 64bit client VM is really
useless.And "No one will ever need more that 640K"

Oracle 9.2.0.6 on Solaris 10

Oracle 9.2.0.6 is certified on Solaris 10, and I had no problem getting it installed. The DBAs had no problem creating 20+ databases either, except that they complained it was slow, very slow.
Config as follows:
System Configuration: Sun Microsystems sun4u Sun Fire V440
System clock frequency: 183 MHZ
Memory size: 16GB
==================================== CPUs ====================================
E$ CPU CPU
CPU Freq Size Implementation Mask Status Location
0 1281 MHz 1MB SUNW,UltraSPARC-IIIi 3.4 on-line -
1 1281 MHz 1MB SUNW,UltraSPARC-IIIi 3.4 on-line -
2 1281 MHz 1MB SUNW,UltraSPARC-IIIi 3.4 on-line -
3 1281 MHz 1MB SUNW,UltraSPARC-IIIi 3.4 on-line -
and a 6120 disk array with a couple of terrbytes.
Oracle is running very slowly for imports, but appears to run okay for sql queries.
There are no cpu, memory or i/o constraints. sar, vmstat, iostat, the usual tools all show a healthy and mostly idle system.
I ran a few dtrace toolkit programs and I see a lot of syscall errors. This output is collected over about 3 seconds.
# ./errinfo -cn oracle
Sampling... Hit Ctrl-C to end.
^C
EXEC SYSCALL ERR COUNT DESC
oracle semsys 4 3 interrupted system call
oracle setpgrp 1 5 Not super-user
oracle kaio 22 5 Invalid argument
oracle open 2 5 No such file or directory
oracle ioctl 6 5 No such device or address
oracle semsys 11 9 Resource temporarily unavailable
oracle shmsys 2 15 No such file or directory
oracle access 2 50 No such file or directory
oracle stat 2 100 No such file or directory
I set a bunch of kernel parameters, despite the fact solaris 10 shouldn't need or use them, but it didn't change anything.
I set all the shm and sem resource controls to log to syslog, but I got nothing showing up.
I've got about 70 servers here, a mix of sun, ibm, hp, linux, and tru64. I've got many solaris 9 with oracle 9i servers and no problems with any of them.
Anyone got any advice?
Thanks
Alan

No i/o wait. The disk array isn't being troubled at all by the load. Using dd to read/write to the array I can get 70+MB/sec.

I've got a downtime this morning to apply the latest OS patches, but I'm not confident that that'll solve anything. On a heavily loaded (60 databases) solaris 9 server an import of a 20GB database takes maybe 5 hours, on this solaris 10 server it takes literally days.
The high sys% and multitude of errors from oracle (via dtrace) leads me to believe that this is some sort of semaphore or shared memory access issue (all those stat syscall errors and semsys shmsys errors). Thing is, I haven't run Oracle 9i on Solaris 10 before, so I don't know if oracle usually throws these errors, but I can't think that it would....

Can DTrace be used to attribute TSB misses to processes?

Let's say I want to find out which processes might be getting most of the TSB misses. Any ideas of how to attribute a TSB miss to the process whose access triggered it? Specifically, I want a count or rate, so I can see which is highest...so that I only have to use ppgsz or mpss.so.1 with those few. I think maybe determining what triggers a call to sfmmu_tsbmiss_exception() may be what I want, although whether that could be related to a process, I have no idea. But if anything short of an exotic DIY loadable kernel hack could be used to figure that out, I'd suppose it would be DTrace.
(I may also cut tsb_rss_factor to 256 from the default, but that's another story)
This is for Solaris 10 (SPARC - a 24 CPU 6800 with 192GB RAM). I've seen trapstat -t overhead percent for some CPUs as high as 20%, and that wasn't when the system was really bad - I wasn't running trapstat from cron yet last time that happened. The system was nearly frozen for some minutes, but there were no I/O errors or anything like that. An xterm displayed back from there would have its scroll bar work fine (no context switch), but even tty driver level echoing was incredibly slow for the shell within that xterm...suggesting that even with very little swap in use, SOMETHING was bogging the system down to the point that a context switch was exceptionally onerous.

SHA is not encryption, it is a one way hash, which means that there is no way (technically feasible atleast) to recover the original text that was converted to the hash.
If you really want to try and make a match (ie, make a brute force password cracker ;) ), perhaps you could make a script to hash the password (of list of passwords) that you want to compare, and compare the hashes.

Anyone have luck with gnu make in a solaris 8 container?

global zone running solaris 10 05/08 (480 hw). got a solaris 8 zone up (flash arcive of one of our solaris 8 systems, NICE!!!). got most items working, except i have probs with gmake (gnu make), any version. ive tried older-current, built from src, and binary packages. all have the same prob.
gmake: *** wait: Error 0. Stop.
gmake: *** Waiting for unfinished jobs....
truss (from inside the sol8 zone)
20050: llseek(0, 0, SEEK_CUR) = 952421

20049: siginfo: SIGCLD CLD_EXITED pid=20050 status=0x0000
20049: wait()
havent tried dtrace yet from the global zone. am i missing some type of privilege outside of the default ones? i can compile and build most open src items with the system make, however we have our own products we build with gnu make.

agreed. though in this solaris 8 zone, i have built openssh, openssl, openldap, mit krb5, sudo, various other gnu utils, and a few more open src projs and all seem to work just fine. test programs ran ok, and i connect via sshd (5.0p1+hpn). we are an isv, and i have had some of our folks run our prods through a bit and so far all those have been ok as well. we are going to run oracle in this env shortly as well as stress test with our prods.
it would be interesting to see what some of the sun folks have to say. with your change to job.c, i was able to run all the make checks, and have used gmake to build a few projects as well. i probably will see what gmake can do building gcc with -j4.
very nice find by the way. hope this does raise a few flags with sun as to why this change would be needed.

Buggy pkgrm in Solaris 10

Maybe out of topic, but I had this problem when trying to remove a pkg from a Zone. So I tried the same command in the global zone, and It had the same effect.
We just had a Package named "wd" working on Solaris 7,8 and 9. It istalled nicely on 10, but when I made a pkgrm wd, the result was a little unexpected:
Among a lot of files also these ones go removed:
/kernel/drv/sparcv9/profile
/kernel/drv/sparcv9/lockstat
/kernel/drv/sparcv9/fbt
/kernel/drv/sparcv9/fasttrap
/kernel/drv/sparcv9/dtrace
/kernel/drv/sparcv9/dcam1394
/kernel/drv/sparcv9 <non-empty directory not removed>
/kernel/drv/sdt.conf
/kernel/drv/profile.conf
/kernel/drv/lockstat.conf
/kernel/drv/fbt.conf
/kernel/drv/fasttrap.conf
/kernel/drv/dtrace.conf
/kernel/drv <non-empty directory not removed>
/kernel <non-empty directory not removed>
/etc/rcS.d/K10dtlogin
/etc/rcS.d <non-empty directory not removed>
/etc/rc3.d <non-empty directory not removed>
/etc/rc2.d/S99dtlogin
/etc/rc2.d/S89bdconfig
/etc/rc2.d <non-empty directory not removed>
/etc/rc1.d/K10dtlogin
/etc/rc1.d <non-empty directory not removed>
/etc/rc0.d/K10dtlogin
I suppose that there is a Bug in pkgrm, since also part of SUNWdhcsr got removed:
I think that should be easy to reproduce. You just need to dreate a pkg called wd, and try to install and deinstall it on Solaris 10.

Sorry for not beeing so precise. I do not know how to file a bug report, because I have Solaris Express for non commercial use. If you let me know how, I could file a bug repport:
I have this problem with Solaris 10 beta 51 and 54. The Version I use now, which also has the Bug is:
cat /etc/release
Solaris 10 s10_54 SPARC
Copyright 2004 Sun Microsystems, Inc. All Rights Reserved.

I have also a problem with mountall in Zones, which is probably also a Bug. Where should I report this one?

Performance hit in audio playback in Solaris 10

Hi,
I've noticed while trying out the Solaris 10 beta 72 that the audio playback quality took a major hit since Solaris 9. I was hoping that this would go away in the Solaris 10 release, but it's not the case.
If I try to play an .mp3 file with mpg123 or even audioplay an .au file, there are regular clicks in the playback, audible about twice per second. Booting into Solaris 9, the audio playback is perfect.
My intuition tells me that the integration of DTrace into the kernel is the culprit, but of course, I have no proof. Can anyone think of a way to test this theory? Can DTrace be disabled? Maybe DTrace can be used to figure out what's going on?

Maybe DTrace can be
used to figure out what's going on?DTrace could certainly be used, but some basic facts would be helpful. As Juergen asked, which audio driver is this and on what machine? And how idle is the machine when audio playback is running? Is the machine power managed?
