SUN T2000 and SOLARIS10 01/06

Hi,
has anyone heard about problems with the above mentioned configuration?
We got
1x T2000 / SOL10
1x 280R / SOL 8
in same subnet.
snoop at 280R "snoops" the whole network traffic
snoop at T2000 "snoops" less than ten percent of the snoop from
280R. Just a few lines per minutes. 280R snoops about 20 lines per second.
We patched the T2000 on the switch port of 280R. But same result.
snoop -P (Non_PROM-Mode) works very well on T2000!!
Are there any software patches we have to install??
We got ipge network devices
Any tips?
regards
Heinz

apologies if you've checked this !
(i) your not using inet6 to snoop on sol 10 and ipv4 on 8?
(ii) does netsta -I ipge0 show any errors (ie do you have faults on cable/card..?)
(iii) as always if above not working I'd look at latest patch cluster or a possible upgrade to 06/06 - however check sunsolve to see if any network issues addressed here!
(iv) in general is your network speed/duplex ok on the niagra box?
best of luck!

Sun T2000 and mpstat, mostly idle

I am running a test on the Sun T2000
mpstat shows that most of the cores are idle.
I have run my test with both writes to disk as well as running completely in memory and the %idle stays about the same.
I had read in Charles Lamb's blog, that he had been able to get a benchmark called JESearchRate, running at 100% utilization.
http://blogs.oracle.com/charleslamb/discuss/msgReader$11
I searched for this benchmark but could not find it. Is it available, so that I can see if it is something about the T2000 or the test of my BDB JE application?

A few ideas come to mind; as always, whether they result in improvement for you is application dependent. They're in roughly the order that I'd try.
You mention that you are using txnWriteNoSync mode. This means that that the JE will issue a system write call for each write operation, but won't execute the fsync. Switching over to txnNoSync mode should show another level of improvement, because operations will not issue the write call, but there will be a corresponding decrease in durability.
Along the theme of trading off durability for performance, you may want to investigate the deferred-write mode that can be set through DatabaseConfig.setDeferredWrite. However, deferred-write mode doesn't support transactional use, and it seems that you are using transactions.
Even in txnNoSync mode, JE still issues write calls as the log write buffer fills up, and fsync calls as the log flips over to a new file. If writes and fsyncs are a bottleneck, you can increase throughput by increasing the log write buffer size and the log file size. Log write buffer size can be manipulated through adjusting je.log.bufferSize, je.log.totalBufferBytes, and je.log.numBuffers. Be sure to verify that you indeed made them larger by dumping environment stats and looking at EnvironmentStats.getNLogBuffers and getNBufferBytes().
Log file size is more straightforward to increase, through je.log.fileMax. You can inspect your logs to verify that the size configuration change took effect.
At the moment, we don't have much to offer for write operations if the bottleneck is latch contention on the btree rather than on the logging system. As you observed, the shared latch setting doesn't do anything for writes. We know that we could do more tuning work to use shared latches in more write paths, especially for operations such as deletes and modifies, but we haven't gotten to that work yet.
Another route to go to reduce contention points is to use multiple environments, if it suits your application. That runs afoul of some other issues, such as the fact that currently a cache is configured per environment, and the use of multiple environments in a single process requires some static division of memory that may not be optimal. (We're paying attention to the fact that we've heard this use case from an increasing number of users!).

Broken pipe - Solaris 10, Sun T2000

Hi,
I have some problems..
So, there's one system I'm working with. It's made of 2 parts (both written in Java):
- "normal" application, that works as a business logic server,
- web application (build on Turbine framework, running on a Resin Application Server) - it works as a presentation layer,
These 2 parts are connected via TCP/IP socket connection - we use an ObjectOutputStream.
It normally works just fine (it's running on several different systems), but recenlty it has been installed on a new server machine and it's started to throw strange exceptions. Below there are informations about server machine, exceptions and code making connections.
We think, that It may be a problem with configuration of Solaris kernel or TCP/IP stack, but have no idea how to fix it.

Hi,
well I'm not sure if it isn't a hardware problem - you see, this system works just fine on a Solaris 10 working on the other servers, but tends to throw exceptions on Sun T2000 machine - so I guess It may be hardware issue and someone here could help me.

Experiences with Sun T2000 servers on SAP systems

Hello,
We are currently involved in a project to migrate our SAP systems from a Windows 2003 to a Solaris 10 platform. Our application server layer will be based on Sun T2000 servers for both ABAP and Java stacks.
I would be interested in hearing from anyone using T2000s in the application server layer to understand their perception of the performance of these systems.
Thanks in advance,
Brendan Byrne

We have actually solved the issues sourrounding performance on sun multi threaded servers.
What you need to do is create a 'Zone' on the solaris server and then allocate resources to the zone.
Then sap seems to fly.
This is fully supported by the way.
Just set this up with NW7 on a T2000 and some T5120's
Basically what occurs is that you setup SAP on one zone.
You then allocate the full 64cpus to this zone, as well as the 32/64gb of ram.
SAP runs as one thread within the zone, but the zone then allocates this thread across all the cpus.
Works like a dream,
Regards
James

SSD in Sun T2000

Hey all,
I'm looking to add a couple of SSDs to a Sun T2000, so I can use Veritas Volume Manager to mirror an existing volume onto the SSDs, and set the read preference to the SSDs, to speed up a database application.
I'd like to not have to trial and error test a variety of SSDs, and am wondering if anyone has successfully installed a 2.5 inch SSD into the 4 onboard drive slots in a T2000, and if so, what brand?
I'm hoping that a standard SATA SSD drive fitted into a drive enclosure would work.
I need roughly a pair of 256gb drives, and there are a number of vendors to choose from (OCZ, Samsung, Crucial, etc. etc)
Any pointers? I can seem to find much info about 2.5 inch SSD drives in Sparcs under Solaris out on the web.

I'm not sure if at first place 256 GB SSD (Solid State Drive) is available & supported on T2000 (searched sunsolve handbook but could not find. Only SSD available is for T5xxx platforms and its 32 GB capacity See : http://sunsolve.sun.com/handbook_private/validateUser.do?target=Systems/SE_T5140/components)
If you want to try for any third party available disks, you may do so but for any problem, it will not be supported by Sun support, if you wish to get.

Sun Creator and using the JNI

Does any developer or Sun person have a direction for me to go in the use of the JNI within Java Sun Creator?
It seems last weekend I was talking to a person from SUN in regards to tis issue and they have not got back to me. Has any one that uses searches looks through this user forum used the JNI within Sun Creator and to what extenet if you have.

Oracle Workflow Server in a SUN machine; and the Oracle

Hi All
I have installed Oracle Workflow Server in a SUN machine; and the Oracle
Workflow Client (Builder) in a WIN2000 machine.
In the SUN machine, I already had installed Oracle9i and OMS (Oracle
Management Server) version 9.2.0.1.0.
In the WINDOWS 2000 machine, I already had installed the Oracle9i
Client and the OWB (Oracle Warehouse Builder) version 9.0.3.35.0. Workflow
Builder
was installed together with Oracle Client components.
I have a OWB (Oracle Warehouse Builder) project, and I deploy and schedule
JOBS in OEM.
Now I need Oracle Workflow in order to better ordering, manage and schedule
that jobs.
I'm reading the following documentation:
Oracle Workflow Guide (Release 2.6.2)
http://www.csis.gvsu.edu/GeneralInfo/Oracle/workflow.920/a95265.pdf But I think Oracle Workflow is very complex to learn quickly.
My OWB Project has several mappings that load tables in a Data Warehouse.
When I deploy these mappings one by one, in OEM, I can execute them in OEM
and they work well.
But when I use the Workflow Deployment Wizard, I create a new Workflow
Project (Item type and Process).
But I can't Launch this process. I go to Launch Process in Workflow page
(http://:/pls//) but when I iniciate the project,
it stops in the OWB Standard Begin Function. It does not go ahead.
Well, when I use the Workflow Deployment Wizard inside OWB, it generates
jobs that can
be viewed inside OEM (Oracle Enterprise Manager) too. But when I submit
these jobs, I can't get success too.
Can somebody help me? May you guide me in order to solve my problem, or send
me some
documents or links about workflow, and it's integration with OWB and OEM?
Best regards

I think this might be more of an OWB question, and how OWB uses workflow, I have sent an email internally to try and get someone to responsd. You should also consider contacting Oracle Support if you are having these kinds of problems.

SUN ray and windows License

Hi,
I want to use sun ray solution with 100 windows client. can someone tell me which is the best license solution. i mean , should I go with windows terminal license or vmare solution.
if you can please explain me about the vmare solution and benefits.
thanks
rajesh

Well to be honest; we don't currently have someone here with full SUN knowledge that can answer that. I am a Windows administrator and trying to find all the applications and appliances whether they are compatible with AD 2008 R2 level. If the Sun Ray and V210 don't have an AD link/integration, that is then actually good news.

Sun plugin and Microsoft VM

Hi,
I have a user base that has installed the Sun plugin (and it is enabled by default), but I would like to make some of the applets on my web site to run using Microsoft VM for Java (note: not "Java VM" :) on their machines even when the Sun plugin is installed and enabled. (Telling them to reconfigure plugin settings on the fly using Tools->Internet Options->Advanced->.... when they enter the spesific applets is far too cumbersome in this case.) My users run other applets that depend on a pure Java VM, so they must have the plugin installed at all times.
It seems that the Sun plugin takes control over the APPLET tag, so I believe it cannot be used and the OBJECT tag should be used instead.
On Win2K, running particular applets in the MS VM can be accomplished by using the OBJECT tag and java: as a prefix to the class name. Example:
<OBJECT ID="Test"
CODETYPE="application/java"
CLASSID="java:Test.class"
WIDTH="400" HEIGHT="140">
</OBJECT>
However, my user base has WinNT4.0 so this won't work on their machines.
I have tried to specify that the applet should be run in the MS VM using an OBJECT tag and a classid that directly refers to the Web Browser Applet Control (clsid:08B0E5C0-4FCB-11CF-AAA5-00401C608501), however, this does not work the way I want it to (the Sun plugin starts instead). And by using OLEVIEW I can see why: There is a TreatAs key for the InprocServer (msjava.dll) there, referring to an object with classid CAFEEFAC-0014-0000-0000-ABCDEFFEDCBB. This turns out to be a "Java Plug-in 1.4.0<applet> redirector".
Also, I have found out that the registry key HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Plug-in\\1.4.0\\UseJava2IExplorer changes its value from 0 to 1 when a user enables the plugin via Tools->Internet Options->Advanced->.... and from 1 to 0 when a user disables it.
My hunch is that the applet redirector, i.e. its Inproc Server npjpi140.dll, either runs the applet or redirects to the MS VM depending whether the registry key UseJava2IExplorer equals 1 or 0.
What I would like to know is the classid of the MS VM component that eventually receives the request to run an applet when the Sun plugin is disabled. My idea is that this is in some way stored inside the npjpi140.dll, however, I would like to avoid having to reverse engineer this file if Sun (or some others) can provide the information.
I have tried all available classid targets from the Registry that have msjava.dll as InprocServers, without success.
Also, if the redirection mechanism is not like what I have described here, I would be very grateful for more information and of course, what I essentially need is a way to solve the problem whether this involves using OBJECT tag and classid's or not.
Thanks!

Kristoffer,
If you have not already found the clisd, it is {08B0E5C0-4FCB-11CF-AAA5-00401C608500} for MS VM version 3805.
I am currently having application conflicts with the newest JRE client and apps that need to use the MS VM. Have you had any luck utilizing both as of yet?

Scott Hannigan

Difference Between Sun JVM and IBM JVM

Hi
Can some one let me on the difference between Sun JVM and IBM JVM
regs
Vivek Nidhi

Sun's JVM is built on HotSpot technology: http://java.sun.com/docs/hotspot
and covers a broad range of OS/HW combinations: http://java.sun.com/j2se/1.5.0/system-configurations.html
Maybe you can be more specific in your question or in describing what you want to do.

Differences between Sun JVM and Microsoft JVM.

Differences between Sun JVM and Microsoft JVM.
I have a very simple applet that I am trying to make compatible with both Microsoft�s JVM and Suns JVM in Internet Explorer.
However, when I turn on the Sun JVM it works occasionally, but frustratingly on most occasions I get the following error messages:
In the status bar: "Applet <name> notinited"
And when I investigate further in the console I get the following output:
load: class <name>.class not found.
java.lang.ClassNotFoundException: <name>.class

It appears that the applet never gets loaded. I have no idea why?
What is the Sun JVM doing here?
Many thanks in advance for any help.

Oh, one more thing. Here's the outpt of the VM log when I run the test above:

Sun Cluster and EMC AX150 does not work

Hi All,
I tried to setup a Sun Cluster 3.2 (2x T2000) with an EMC AX 150 Storage. the device paths are highly instable and breaking down time and again. Tried to install Powerpath software of EMC but this time the did-devices are not recognized by Sun Cluster.
Any help will be appriciated.
P.S: does anybody know whether a MSA 1000 will work with Sun Cluster 3.2.
Regards

Looking at the EMC link on http://www.sun.com/software/cluster/osp/ it doesn't look like these storage systems have been tested by EMC and so may or may not work.
You could try using Sun's MPxIO rather than PowerPath. MPxIO is included in Solaris for free. Again, it may or may not work. You are unlikely to get support on either configuration until EMC has done the prerequisite engineering testing to resolve the sort of issues you are currently seeing.
Regards,
Tim

Sun c4 and veritas netbackup 6 mp4 installation

Hello, please help me!
We have SAN with 2 st6140 and 3 broacade 200e switch. One site is: two 200e and 3 linux hosts, other site is: v240 server (one FC port) with solaris preinstalled and installed Veritas NetBackup mp4, 1 200e switch, Sun C4 library whith FC ports.
On second site I connected C4 FC host port to the 200e swith, FC port on v240 also connected to the 200e switch.
Can you describe me a common porcedure to configure correctly a server with Veritas and C4?
I cant add "device" in veritas Administration console now, because it cant see nothing.
How i have to connect C4 and Veritas server to SAN correctly ?

create a soft zone on your brocade , with your C4's FCs ports and your Netbackup Master server, for Netbackup use version 6.5 , not 6.0
once you activate your zone, run cfgadm -al -o show_FCP_dev, you should be able to see your paths, one path or more paths from your server, two or more from your C4 libraries' fabrics, netbackuop 6.5 is very clean and installed , to be able to recognize your drivers ...once the software installed, go to your GUI, to configure device...
Also, use the latest version of Solaris10 on this..it is much cleaner to work with netbackup 6.5
