Performance on sun

Hi ,
i have sun 280 that runs oracle 9i .
I get poor poor performance on it comparing to just "regular" pc machine that runs oracle.
io wait of up to 50%
only one user logged to the system for testing.
doing loop of insert 100000 takes 3 minutes on sun and about 20 sec on windows.
is there a known problem with sunfire internal disks ?? and Oracle ?
I came across such thing but nothing solid so far.
thanks

This is not a COMMIT bottleneck, otherwise we would see LOG FILE SYNC wait event. I referred to this technical information:
Symptoms
You are observing poor performance while Oracle writes to redolog files:
1. Statspack report shows very high wait time for event 'log buffer space'.
2. alert.log shows increased time between log switches.
3. Disk activity shows high IO wait and poor throughput.
4. The system may or may not be implementing RAID.
Changes
Making the below changes do not help :
Increasing the value of log_buffer.
Setting disk_asynch_io=FALSE
Cause
The problem occurs because the write cache on the disk has been disabled.
The write cache is an area of temporary volatile storage that has a faster access time than the actual drive media. Its purpose is to increase throughput.
In case of RAID implementation, this cache is primarily a mechanism to defer writes, so that the overhead of calculating and writing parity information can be done by the system, while it
is relatively less busy.
Fix
Switching on the disk write cache will resolve the problem.
Please note that when disk write cache is on, it is the responsibilty of the OS/disk to ensure that all that is written to cache is written to disk. .

Performance of Sun's J2EE1.4

Hi all,
I'm currently building a prototype on the Sun J2EE Server 1.4 to use some of the new features in the 1.4 to solve a problem that's currently a bottleneck in our current 1.3 solution.
I wonder if you have some impressions about the performance of Sun's J2EE1.4 compared to JBoss 3.2.x or Weblogic 8.1.
It really doesn't have to be as fast as the others, but if it's 10x slower, I'm in trouble as we want a 10x improvement in performance with the new solution. (Of course, if Sun's J2EE impl. is 10x slower than the others and I still achieve 10x improvement just sit back and wait until JBoss 4.0 is out! :0)
Any opinions/observations/impressions?
-regards,
Gerard.

Hi Binod,
Currently we are using a clumsy legacy implementation to go to an external system that is synchronized everywhere and for everything.
I'm trying to replace this interface by a connector (see the relation with my other posts :-) and my plan is to take advantage of the connection pooling and re-use offered by the container. (Now a TCP connection/bean is created). The communication with the external (real time) system is async bi-directional (formely solved by bridging the incoming msg to JMS), hence my need for a JCA 1.5 connector.
My question regarding the AppServer performance is in general terms. I remember the J2EE1.3 RI being very slow when compared to Weblogic, but given that Sun is proposing the 1.4 RI as the developer edition of the full-fledged J2EE server, I expect it will do much better in this regard.
Kind regards,
Gerard.

Performance in Sun Java Communication Suite 5 between Solaris 9 and 10

Somebody knows which is the best Operation System to deploy the Sun Java Communication Suite? in performance terms?
I have and old Sun Fire 280R with two 750 Mhz Processors, 3 GB Ram, and an A1000 Storage.
Thanks a lot,
Andres.

Poor Performance of Sun One Web Server 6.0 SP6

We are running on an E450 with 2GB of memory, Solaris 8 2/02 with Recommended and Security Patch Cluster from 31 Jul 03, Sun One Web Server 6.0 SP6, Macromedia ColdFusion 5, JDK 1.4.1_02. We are seeing intermittent (three or four times a day) performance problems, extremely poor response time.
A vanilla, �test� iPlanet web server was put up on port 2443 with https turned on and off. Repeated control tests on file operations (�copy link as�) showed similar results as those described in High Impact above. Changes to add KeepAlive parameters (in magnus.conf) showed no noticeable improvement.
Tests were conducted -- on the test server -- accessing the same file from two clients, one a thin client (TC), the other a Unix workstation (UW).
Results:
1) Sometimes process TC was started first and continued normally while process UW hung up; when this happened, only one httpd process was building cpu time;
2) Sometimes process UW was started first and continued normally while process TC hung up; when this happened, only one httpd process was building cpu time;
3) Sometimes both process TC and process UW continued normally regardless of which was started first; when this happened, two different httpd processes were building cpu time together;
Speculation on Process Management - speculation is that, in the case of the 3rd bullet above, iPlanet assigned different httpd processes to the two requests. In the case of the first two bullets, however, the belief is that iPlanet actually assigned the second request to the same process it had previously assigned the first request. In this case, the second request was left to wait. It appears that most of the work done by httpd children is performed by only two or three children, even when there are 10 available.
Questions;
Why are the other httpd children are not more fully utilized?
What about changing the number of Acceptor Threads?
Could turning on Native Polling help (UseNativePoll in magnus.conf)?
Any other thoughts about what is going on or how to fix the issue?
Thanks for any assistance

Because the security context is set as a process context, the NSAPI thread locks the process prior to setting the security context. The older NASPI plugin that we are using is not reentrant, it will not work with the mulitthreading model. Under multithreading each thread would have access to the security context of each thread.

RAID-1 performance with Sun v40z

We are using Sun v40z machines with built in LSI RAID controller (RAID level 1). I was wondering about the performance of RAID on these machines. Our application does a lot of I/O (mainly random and sequential reads). Since we are using a RAID-1 system with two disks, I expect the performance to be good, but it is not, and it seems that all read requests are served from one disk. We are running RedHat Linux 4.
For investigating, I used dd to read a large file and write it to /dev/null. During this operation, iostat showed around 400-500 transactions per second with 100K blocks read per second. When I instead run two parallel dd command to read from two different files, number of transactions per second drop dramatically to 100-120, with just 30-40K blocks read per second. This is very bad given that we have two disks mirrored using RAID-1 and both should be readable in parallel.
I have conducted the same experiment on a different machine (Linux desktop, non-Sun, without-RAID), and I was able to read 75-80K blocks per second with two parallel read processes.
I am using:
time dd of=/dev/null count=5000000 bs=16k if=file1.txt
time dd of=/dev/null count=5000000 bs=16k if=file2.txt
I haven't configured much with the RAID controller, it is as it came with the machine. Infact, I was not able to find any documentation or support about the RAID hardware on these machines from Sun's v40z site. If you know of location of documentation, please point me to it.
Any help about how to improve the performance will be appreciated.
thanks in advace,
Nilesh

Most controllers will simply round-robin between the two disks, so you shoudl not expect any performance improvements between a single disk and RAID1. SVM has a "geometric" read option which theoretically can help large sequential reads, but it defaults to round robin, and my guess is that most embedded controllers do as well.
Most likely read performance falls off as you try two file copies because you are trying to copy the same file. The two processes are trying to read the same disk sectors, so one of them is going to have to wait for the disk to spin around to the same sector the other process just read. There are lots of other reasons why this could happen. You should see the same effect with a single disk.

Questionable performance of Sun Storagetek 6140

Hi
I've got StorageTek 6410 with 16 FC 15K 68GB disks connected to Sun M4000 (SPARC) with two 4Gbps Qlogic HBAs (2460). OS is Solaris 10 5/09.
I tried everything - creating RAID1, RAID5, RAID10, block size 256, 512k volumes, ZFS or UFS. I'm getting maximum average write performance of 80-160MB/s.
Tested with dd and iostat. In another thread someone claims that it has to be at least 260MB/s. What's wrong? Maybe dd is not good for testing? What parameters can i tune?
TIA

Following example is RAID5 volume of 8 disks and 512 KB block size, but im getting similiar results with RAID10 volumes:

Performance Hotspot: sun.awt.GlobalCursorManager._updateCursor

I am trying to optimize a Swing-based application that has custom Swing components. When I run OptimizeIt, I get a hotspot in the sun.awt.GlobalCursorManager._updateCursor method. This method appears to be taking up 20-30% of the processing time when I do a simple operation with the GUI, and I can't figure out why.
GlobalCursorManager._updateCursor is called during calls to the validate method. All the time spent in the validate method is spent in the _updateCursor method. I'm running JDK 1.4.2, but the code for JDK 1.3 for this method is:
     * Updates the global cursor. We apply a three-step scheme to cursor
     * updates:<p>
     * (1) InputEvent updates which are outdated are discarded by
     * <code>updateCursorImmediately(InputEvent)</code>.<p>
     * (2) If 'useCache' is true, the native code is free to use a cached
     * value to determine the most specific, visible, enabled heavyweight
     * because this update is occuring in response to a mouse move. If
     * 'useCache' is false, the native code must perform a new search given
     * the current mouse coordinates.
     * (3) Once we have determined the most specific, visible, enabled
     * heavyweight, we use findComponentAt to find the most specific, visible,
     * enabled Component.
    private void _updateCursor(boolean useCache)
        synchronized (lastUpdateLock)
            lastUpdateMillis = System.currentTimeMillis();
        Point queryPos = null, p = null;
        Component comp;
        try
            comp = findHeavyweightUnderCursor(useCache);
            if (comp == null)
                // Cursor is not over a Java Window. Do nothing.
                return;
            if (comp instanceof Window)
                p = comp.getLocation();
            else if (comp instanceof Container)
                p = getLocationOnScreen(comp);
            if (p != null)
                queryPos = new Point();
                getCursorPos(queryPos);
                Component c = findComponentAt((Container)comp,
                                  queryPos.x - p.x,
                                  queryPos.y - p.y);
                // If findComponentAt returns null, then something bad has
                // happened. For example, the heavyweight Component may
                // have been hidden or disabled by another thread. In that
                // case, we'll just use the originial heavyweight.
                if (c != null)
                    comp = c;
            setCursor(comp, comp.getCursor(), useCache);
        catch (IllegalComponentStateException e)
            // Shouldn't happen, but if it does, abort.
    }[Sorry, but I can't find the source for this class in the JDK 1.4.2 SDK, since it is not part of the public API.]
The hotspot is somewhere in this method, not in any calls this method makes. Looking at it, the only thing I see that might be causing the problem would be the synchronization at the beginning of the method. Everything else looks fairly simple, or includes calls to other methods that would appear in the profiler.
All the processing for the application is running on the AWT-EventQueue-0 thread, so I don't understand why the synchronized part would have a problem.
Does anyone know what may be causing this problem? Also, if someone has the updated 1.4.2 source for this class, it might help me figure out what the problem is.
Thanks.

Oh, also, since this might be part of the OS-specific code, I am running on Windows NT SP 6a with JDK 1.4.2.

Performance Tools Sun Studio 12 under Ubuntu

I want to use the hardware counter under a x86-64 Ubuntu (Feisty). But the system isn't supported by the performance analyzer and the hardware counter aren't available. Exist any opportunity to use it or should i install red hat enterprise or suse enterprise. Gives there any free OS where the HW counters working?

You can try Sun Studio 12 on any machine you want. The 'unsupported' means: it's your choice, you are at your own risk, you are on your own. However, we still would be willing to hear from you, we would also help if we can. Your input and feedback are welcome!
You can even file RFE on bugs.sun.com if you feel the performance on Ubuntu is better, worth recommended, worth to be added to the 'supported platform' list, etc. Voice of Customer is always welcome too!

Sun T2 chips vs SPARC64 VI/VII chips for Oracle database servers

We have recently found poor performance of Sun T5240 servers where (against previous V series servers with similar gross I/O capabilities on the disk volume)the timings for the recovery of the database, and the subsequent re-build of the tables and materialised views, are variable from slightly worse to atrocious. Given that the clock-speed is similar,and all significant oracle database parameters are the same, we couldn't see why these processes should take longer on the T5240. The statistics report from the database showed no I/O bottleneck on the new machine, instead it showed raised CPU times for some of the key slow statements.
We found the attached oracle metalink document (ref 781763.1) <<Sun_T2_slow_for Oracle_DB.html>>
Seems to be that if you can't control the content of large long-running SQL statements to parallelise them, don't buy a T-series box as the multithreading capability will work against you.
Therefore we are looking at new servers to run other similar large Oracle apps and appear to have a number of choices within a similar price range
Notably
M3000 - 1 x SPARC VII CPU (quad core procesor)
M4000 - 2 x SPARC VI CPU (dual core processor)
as opposed to the
T5240 - 2 x T2 CPU (8 core processor)
Question is which of these CPU/Core combinations works best...are there performance figures? What's the difference between CPU's and number of cores?
Any benchmarks to help us decide? Anyone experienced similar or tried these different combos for themselves?

We tested a T5210 as a database server (running Ingres, not Oracle) and our batch performance was roughly equivalent to a dual CPU UltraSPARC III V480. Our guess is that the performance hit came from having a relatively small cache shared across so many threads. Like you, we're looking at using the M3000 or M4000 in preference.

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

Sun JPI support

Hi,
Any news/thoughts on the support of Sun JPI with MS IE? The SOD on OTN states this is targeted for "patch 2". Is this the forthcoming 10.1.2 release?
When Sun JPI will be supported, which version of JPI would you expect to be required? 1.4.2 or 1.5?
Currently we're using Forms 9.0.4.1.0 with JPI 1.4.2 without any major problems. However, 1.5.0 doesn't seem to work (very slow network connection through firewall and hanging IE when closing browser window).

Thanks for all the answers.
We're currently running into two issues with v1.5:
- Internet Explorer doesn't close when pressing the top-right "X". Not even if you've exited the Forms application in a proper way. You'll have to kill IE. This issue does not arrise with Firefox (it seems to destroy its Java environment in another/more destructive way).
- Performance with Sun 1.5.0 is very poor when connecting to our application server through the firewall (Initial connection approx. 2 minutes). Connecting from within the DMZ is not an issue.
Both issues do not arrise with 1.4.2 or with JInitiator. So, I guess I'm just giving more reasons to stick to a certified combination :-)

Oracle Discoverer Plus Performance

When trying to connect to the Discoverer on the Web, we need to wait a very long time(about 5-10 minutes!)
for each web page to be displayed ( those are the simple trivial pages of userid, query list, parameter window for running a query, etc…).
When we eventually get to run the query it runs very fast, so the problem is not the performance of the database.
It seems like the access to the web pages on the server or something to do with the JAVA is not working properly.
We tried to address the link for the discoverer plus with the server name and also with its IP address but the result was the same.
We tried a higher version of Java and it was no good.
The station from which we are running it, is a very strong one so it is not a problem of shortage in memory etc..
Do you have any idea how to deal with this problem?

Hi Hadar,
In general, I would recommend making sure the JRE being used is compliant (see these Knowledge Base articles):
Recommended Client Java Plug-in (JVM/JRE) For Discoverer Plus 10g (10.1.2) [ID 465234.1],
Discoverer 10g (10.1.2) Plus Applet User Interaction Has Slow Performance With Sun Java Plug-in 1.6.0_03 or Higher [ID 747189.1],
Slow Performance Launching Discoverer Plus 10.1.2 With SUN JRE 1.6 [ID 579211.1]

What Sun Studio 12 patches are included in Sun Studio 12 Update 1?

I can't seem to find a bug list or patch list for Sun Studio 12 Update 1. Can someone provide a link or list of what was fixed?
Secondary, how do I know I have Sun Studio 12 Update 1 installed? Does CC -V say 5.9.1?
-kto

I'm not sure about your bug list or patch list question, but on your second question you can use the "version" command.
Just point it at the Sun Studio component you want to check. So for the CC compiler :
% version sunstudio12.1/bin/CC
version of "sunstudio12.1/bin/CC": Sun C++ 5.10 SunOS_sparc 2009/05/02
You can also just type "version" and that will list all the
components of the Sun Studio that are in your PATH, like so :
% version
Machine hardware: i86pc
OS version: 5.10
Processor type: i386
Hardware: i86pc
The following components are installed on your system:
Sun Studio 12 update 1
Sun Studio 12 update 1 C Compiler
Sun Studio 12 update 1 C++ Compiler
Sun Studio 12 update 1 Tools.h++ 7.1
Sun Studio 12 update 1 C++ Standard 64-bit Class Library
Sun Studio 12 update 1 Garbage Collector
Sun Studio 12 update 1 Fortran 95
Sun Studio 12 update 1 Debugging Tools (including dbx)
