Upgrade to Patch 28 causes serious performance decrease

moved message to implementation forum.....
Message was edited by: Marcel Rabe

Hello all!
1. It is interesting to note that Oracle LGWR process under Solaris 10 showes less cpu instructions per cpu tick. Smth about 15% as compared to Solaris 9. You can see it with cputrack utility. If using truss utility you can see that each system call takes more cpu time. Just the same 15%. That is so in the best Solaris 10 configuration when /etc/system is empty (with only some Oracle settings left).
2. There is a very interesting Sun note 90051 about Solaris 10 memory fragmentation caused by using 4M memory blocks with Oracle 9i. This is the most possible reason for our troubles after migration from Solaris 9 to Solaris 10.

OPBHOBrokerDsktop.exe is causing serious performance problems on my new Windows 8.1 PC.

Browsing websites with Process Monitor running, there are millions of instances of this executable running in the background. It apparently causes websites being browsed to go into a "not resplonding" state. I use Webroot for security, and the computer is new - purchased about 3 weeks ago - HP Slimline.
The .EXE is installed as part of HP's "Simple Pass" which was apparently installed on my system when I downloaded a driver for my HP Officejet Pro 8500 printer/copier/scanner/fax.
It's supposed to be an identity protection software. Does this program actually work? I want to uninstall it because the performance impact is just ridiculous.
Thanks for any advice or suggestions you can provide.

I'm having the same issue with my new HP Envy 8.1 . I had to send it in at least 2 times for factory repairs. OPBHOBrokerDsktop.exe shows up as a warning in the reliabilty monitor now. Maybe that's what made my monitor and motherboard go out before. It has always showed the "simple pass broker" or -"OPBHOBrokerDsktop.exe"- as a warning . I thought it was that I just didn't scan my finger over the sensor right. When you hit the the link to find a solution about the warning. It says no solution found.Also it doesn't start automatic maintenance on schedule. Here just a few days ago in the start up screen it asked if I would like to use a PIN number to log in instead of "SimplePass". But it didn't say why. Now I'm beginning to understand why. They won't admit there is a problem either. I had a remote session today because the automatic maintenance scanner ran for 11 hours and never completed. All they told me to do was to do a factory recovery back to factory defaults, and to save all my info. They must know by now that there is a problem . Why can't they find a fix instead of just resetting to factory defaults. This will make twice now I've had to reset my computer. A $ 1000.00 computer that has so many problems "brand new !? I bought it new custom built in "China". But the "Recovery Manager is a black control panel, meaning it was manufactured before 2013. A white Recovery Manager page means it is 2014 or newer. I bought mine new custom built in June 2104, and it shows it was manufactured before 2013 . So I have a old windows 8 computer that was updated to 8.1 . They sold me as a NEW computer. That could be why I'm having so many problems with mine.

JSP causes serious performance problem in my EP

I have a native JSP application and running it on the EP. This application accessing a Oracle db (using oracle.jdbc.driver.OracleDriver driver).
When this db not running, my EP doesn't open any page. The EP try to connect with this db, but not get success.
I modify this application with TRY and CATCH to treat the application problem, but the EP problem continues.
In the EP Thread Overview (System Adm -> Monitoring -> Portal -> Thread Overview), I see threads (locked) about this application. To unlock this threads, I delete the par file from the Portal and re-deploy it.
When this threads is deleted, the application treat the problem (display a error message in the iView container) and EP work normally.
My questions:
1) Exists some way that the problem with this application does not cause performance problems with the EP (via code or property)?
2) Exists some property in the Config Tool where I configure the connection timeout for access the external DB?
3) Exists some way to liberate these (locked) threads of the EP (I see the page Clearing the Portal Runtime Cache - http://help.sap.com/saphelp_nw04/helpdata/en/d2/a216e1bd7b431c82fa5ff105187112/frameset.htm - but I don't know if I can use it for this)
I use EP 6.0 SP 15.

Severe Samba performance decrease after u6 - u7 upgrade

I just upgraded my Solaris 10 x86 system from u6 (kernel 138889-08) to u7 using LiveUpgrade. I have samba sharing some ZFS filesystems, and the first thing I noticed after the upgrade was a severe performance decrease in reading files via smb.
For example, using smbget from a MacOS client to retrieve a particular test file, pre-upgrade I was getting about 30Mb/sec, but after the upgrade to u7 I'm only getting 100Kb/sec. If I boot back to my alternate boot environment that still has u6, performance returns to normal. This happened when u7 was first released, so I just ignored it and went back to u6, and now I tried u7 again yesterday and applied all of the current security and most recommended patches (including the latest samba patch) and am still experiencing the same behavior.
I don't currently have any socket options or other performance tuning in my smb.conf, it is about as simple as possible with just a couple share definitions.
Any ideas why the upgrade would cause such problems for samba? The only troubleshooting I can think to check is that the network card (e1000g) isn't getting errors all of a sudden after the upgrade, but netstat -i shows everything is working as expected; 0 errors/collisions/etc.
Any suggestions would be appreciated!
Thanks,
Matthew

Serious performance problems after updating from 10.5.6 to 10.5.7

I've got a Macbook Pro C2D 15" (late 2006). After updating the system from 10.5.6 to 10.5.7 and quicktime to 7.6.2, I experience serious performance problems which I have never seen before:
-From time to time, kernel_task has peaks in activity monitor (consumes a lot of CPU). In that moment, the mouse hangs for a short moment and audio playback is distorted/has drop outs.
-Recording audio consumes a lot of CPU (independent of the audio application).
-Video playback consumes a lot of CPU, regardless if I use VLC or the quicktime player.
Any idea what could be done? Thanks in advance.

After a few days of using CoolBook I report that my 1st generation MacBook Air is now reliable and never overheating, regardless of environment conditions.
I must point out that I do believe that it really is something new in 10.5.7 that is causing this problem as my environmental conditions have not changed and even Summer in Dublin still sees temperatures no more than 72F/22C. I am now in Madrid, where the environment is quite different, and I am still having no problem with kernel_task spinning.
I plan on reporting my problem to Apple anyway and being aggressive about the issue as MacLovinRanga did in this thread (http://discussions.apple.com/thread.jspa?messageID=9647353#9647353). Perhaps many/all of those of us having this problem will obtain new MacBook Airs.

Database rolling upgrade cpu patch with minimal service outage

Oracle 11gR2 Primary Instance
Oracle 11gR2 Active Physical Standby
Requirement of applying CPU and CVE patches with minimal downtime. I believe that I've been able to apply CPU patch to Active Standby after deferring redo transport and applying patch to active physical standby first and then performing a manual switchover to have the standby become the primary and former-primary become the standby and they apply CPU Patch there and then perform another role transition to its original role.
Appreciate your experience with primary and active physical standby rolling upgrades/patches. Thanks

Hello;
I believe you are over thinking this. All you have to do on the Standby is install the patch. No switchover, no SQL. No nothing.
The SQL will move from the Primary to the Standby.
Check the readme for the patch closely or post the patch number if you want to confirm.
OR
How do you apply a Patchset,PSU or CPU in a Data Guard Physical Standby configuration [ID 278641.1]
( If it helps I had the same thoughts after my first Data Guard setup !! )
If you are trying to avoid downtime entirely the switchover will take about as long as the patch.
If you have RAC this is interesting :

Recent windows 7 updates caused serious conflicts??

I have two NI PCIe-1433 boards and the NI Max v5.4 installed. Recent win 7 (64 bit) automatic updates, within the last 10 days seemed to cause serious problems. Win 7 couldn't boot any more. Sometimes computer turns on and off by itself before the windows logo shows up. Sometimes it crashes before I can login.
I did a fresh reinstallation of win 7. The same problem happened after some automatic updates. I can boot and use windows 7 if I unplug both NI cards. This makes me think the problem is in NI driver/card. I'm reporting it here to see if anybody experiences similar things.
Earlier this year Win 7 automatic updates caused a problem with my Canon printer/scanner. Canon supplied scan software still does not work today.

Hi Jeremy
Thank you for responding. I do not know which update. I know it's due to some update(s) that happened recently.
After I reinstalled the fresh Windows 7 (64 bit), I installed NI IMAQ software. I was able to use both boards to acquire images at that point. However Windows 7 kept updating itself. Later the same problem happened again.
After unplugging both boards, I have been using the computer for 2 days without a problem. My computer's power supply is 650W. Does the boards require a lot of power?

Bug report: Energy Manager causes slow performance...

Very slow Windows Startup..
Energy Manager's plans and the problem occured using any plan as I remember, and it wasn't an issue with the maximum processor state. I had heavy disk usage, especially access to the Page File, which is what the person in the second link I posted also described. CPU usage was low. The disk usage was seemingly not related to Energy Manager (Chrome was usually the worst), but removing Energy Manager completely resolved the problem. If you would find it helpful. I'm quite confident that even with Maximum Processor state at %100, CPU usage was low when it was slow, and that disk access was the culprit.
previously have use 1.0.0.31 or 32 not sure.
Windows 8.1
Im using Lenovo Energy Management Driver
1.0.0.28
4.6.2014

I actually have the same problem. Sorry to work on a old thread, but...
I've got my Lenovo B50-70 less than 1 month ago, and had switched it to SSD and had set everything up and is working perfectly. However there are a bunch of lenovo programs that came pre-installed. This computer is used mainly for work and I really don't like programs that suddenly pop-up and ask you to do stuff, as it is quite distracting, and with Lenovo Energy Manager being one of them so I removed it. (I did do some research before I remove...)
Everything was fine, until when I try to switch on my wifi (I usually have it off, as I use LAN most of the time)... For the B50-70 there is a airplane button on F7, which allow the user to switch wifi and bluetooth on/off. That button was unresponsive... After some digging it is actually related to the power energy manager being removed. So I've downloaded the latest version from Lenovo and it was working again...
However though, whenever I start my computer it is taking so long to start... And I tried uninstalling the power energy manager and it solved the problem... And I am stuck with either having no wifi on/off ability or a really slow boot, which loses the whole purpose of the SSD. After you enter your username and password it originally takes around 5~10 seconds to login, now it takes over 1 minute.
I have found this other link, which says Lenovo Power Manager having the same problem.
https://forums.lenovo.com/t5/ThinkVantage-Technologies/Bug-report-Power-Manager-causes-slow-performa...
There is a solution, which you can change the registry to switch a function off. I've tried it and it didn't work, which is not surprising as it's a different program.. But I am hoping that Lenovo can provide a similar solution for Lenovo Energy Manager...

Serious performance problems on iWeb site

Can anyone help me find the problem with peterlance.com? It looks like author Peter Lance uses iWeb to update his web site. He redesigned it recently (and did not use iWeb for the old design). Anyway, it has serious performance problems on Internet Explorer, which I was hoping you guys could help pinpoint? Is there something simple I can tell him to try to fix the problem? He is launching a new book on Tuesday so he will be getting a lot of traffic, but for now the response time is not very good. Any suggestions?
In particular, each new page seems to hang for about ten seconds and freeze using Internet Explorer 6. Any fixes?
I mean, fixes other than: "Don't use Internet Explorer!"

Welcome to the discussions, TopDog08.
There are several plain .jpg's and that's good, but you need to convert every .png on the page (or as many .png's as you can) to a .jpg. For example,
http://www.peterlance.com/Peter%20Lance/Home/Homefiles/shapeimage46.png
Convert that to a jpg, then replace the graphic and text on the iWeb page with this converted jpg (some have has success using Downsize http://www.stuntsoftware.com/Downsize/)
The ones you won't be able to do anything about are the ones that are a part of the blog, but that will be only 5 images instead of the many you have now.
This image
http://www.peterlance.com/Peter%20Lance/Home/Homefiles/shapeimage50.png
Is covering part of your menu which is why it appears that only the top half is sensitive to rolling over. You'll have to adjust your layout to account for this.
Another area to look at, there are white boxed png's surrounding the amazon book covers at the top.
http://www.peterlance.com/Peter%20Lance/Home/Homefiles/imageEffectsAboveAli%20Mug%20TPI%20jpg.png
Another set of .png's you'll have to get rid of. How did those get put on the page?
What you see happening with IE is a java script running to fix IE's problem with png's. The fewer .png's you have, the less of a problem with IE you have.

Performance Decrease with ComboBoxes

Memory consumption and bad performance decrease when closing and reopening panels containing ComboBoxes.
Context:
- Running localMode
- Jdev 9.0.3.1 DE
- Business Component Version 9.0.3.10.62
- jdk 1.3.1_02
Panel (within an JInternal frame) with some JUComboBoxes with LOV-Binding to ViewObjects, only with a few entries (2-20)
We observed, that the count of JUIteratorBindings encreases with every new Panel (re)open.
After closing the Internal Frame (including the Panel) the IteratorBindings of all ComboBoxes keep alive and a set of new ones are added to the PanelBinding when opening the (same) Panel once more.
Is it a bug?
Have one to remove the IteratorBindings explicitly?
Is there any configuration possibility, that the IteratorBindings die with the Panel?
Has anyone the same problem?
Roswitha Stepputtis

Yes, we experience similar problems. My suggestion would be to simply hide (setVisible(false)) your internal frames and reuse them when you open them again.
So, instead of dynamically re-creating your JInternalFrame instances, you keep a reference to them once they are created and reuse them each time they should be made visible. I think this will make your application more efficient as a whole.

JDev10g: General performance decrease with JClients like Oracle BC Browser

Hi,
I'm observing a significant performance decrease of JClient applications (homegrown and Oracle Business Components Browser)in JDev10g compared against JDev9i (9033)?
Can anyone confirm my observation?
Just create a default Dept-Emp business components package and start the Business components browser. Scroll to some data (it takes some time...) and resize the window (takes even more time)!
My guess: JDev9i-style data binding for JClients is simulated in JDev10g with ADF-Data-Binding?? My own application is a simple "recompile"-migration of a JDev9i project with JDev10g. Does this apply to Oracle Business Components Browser too?
My own application runs still faster with JDev9i!
What is the problem? Any hints are welcome!
Thanks,
Markus

Excellent Blog. Thank You
Small clarification on Step **6) Oracle Home Directory, ...a) Resize the Root Partition**
Ubuntu 11.10 has Gparted available as a Ubuntu software download, DONT use that while trying the above step, instead download the ISO file from http://sourceforge.net/projects/gparted/files/gparted-live-stable/ gparted-live-0.12.0-5.iso (124.6 MB)
Burn that ISO file on a Blank DVD, reboot the Ubuntu , during startup select Boot from DVD Option if not already selected. this will take to Boot Menu Options of Gparted Live then select the first menu option, and this allows to do further action such as Re-sizing .
and once you have chosen and executed step a) . do NOT run step b) also that is "Setup External Storage"
I hope this minor clarification can avoid some confusion

Serious performance problems

Hi
I am having some very serious performance problems witgh java web start. I have a swing client that transmits XML/HTTP to and from a server, parses it, etc... I am finding that the XML/HTTP data request
is a factor of 10 to 100X slower, at least, using Java Web Start than without.
Any suggestions would be helpful
Thanks
Charles

Charles,
I've also observed some overhead when running an application deployed with JAWS compared to running the application from the jar, or in my dev environment.
After searching these forums a bit, I found this buried nugget of info: Try System.setSecurityManager(null) if you are requesting <all-permissions/> already.
Before the workaround, my application was taking 194 seconds for a single analysis run. After this workaround was applied, the same analysis run took only 82 seconds.
So as you can see, there is considerable overhead associated with performing operations through the layers of security (my guess). My particular application does a lot of disk I/O (which is probably something the security manager watches closely).
I stress the 'workaround' aspect of this because I haven't fully investigated the ramifications of using it, but eventually this might turn into a bug submission (because if I'm already requesting all-permissions, why do I still need to do setSecurityManager(null)?).
At any rate, hope this helps!
