9i performance issues in windows 2000

I have imported the database from 8.0.5 to 9i recently and have been facing performance degradation although 9i is running in a better server with more memory and processor speed.
The same application, use to run more efficiently with lesser db_block_buffers & shared_pool parameters.
I have modified various parameters recommended to run 9i on win 2000 but still there is no great improvement.
One of the key area where I suspect the problem could be is, I see more wait in control file parallel writes/reads events.
Can someone help me out on this. Also it will be more useful if someone can help me to find a document to optimize win 2000 for 9i.
Thanks

Did you reanalyze all your objects using a large sample size?
With every upgrade a few queries could change plans and the plan changes are not always for the best. Just one or two poorly performing queries could adversely affect the entire system.
Have you reviewed your physical and logical IO hog lists to be sure that you just do not need to tune a couple of queries.
Remember also that at least 6 common init.ora parameters affect CBO choices and you should look very carefully at any changes made to the init.ora (db_file_multiblock_read_count, sort_area_size, hash_join_enabled, optimizer_index_caching, optimizer_index_cost_adj)
Finally a big part of overall database performance is disk layout and performance. Even with a faster cpu and more memory if your reduced the number of spindals available to support your db activity you could have shot yourself in the foot (so to speak).

POA performance issues under windows 2008 R2

Hello - we are running GW 8.02 hp3 and recently moved our main post office (~600 users) from Netware to Windows 2008 R2 (running under Vsphere 4.1).
We have started seeing intermittent slow performance issues esp. when moving a message from one folder to another, or sending a broadcast email.
It doesn't appear to be a hardware resource issue: disk queues don't exceed 1, with low latency (7-15ms) and we're not cpu or memory bound (that I can see).
Here are our current config settings:
Message Worker Threads: 15
Maximum GWCheck Worker Threads: 8
C/S Handler Threads: 30
Max Physical: 2048
Max App Connections: 4084
Soap Threads: 20
We don't see any serious errors in the logs when performance becomes slow. Could this just be a tuning issue?

of what you are hitting.
How are you monitoring memory usage? I've found that the vCenter tools
aren't a good indicator of that, where as the Windows tools are better
in that respect. The biggy is that you don't want much paging to disk.
How much do you have assigned to this VM?, how many cores? And are
these ESX box(es) over committed on those two?
Those settings on their own don't really mean a whole lot. What we need
to see is what is actually being used, and if you are running out of
them, then upping those specific numbers can help. The best way is to
watch the POA web interface for the relevant settings.

Mac G5 10.3.9 Samba Issue with Windows 2000 Advanced Server??

I have just installed a new Windows 2000 Advanced Server network but the Mac G5s running OS X 10.3.9 Panther cannot navigate the server - the finder just hangs with a beachball. The PCs can navigate without any problems.
Navigation is fine on the G4 running OS X 10.2.8 Jaguar on the same network.
On the G5 I have tried creating a new user and put the Mac using DHCP but this doesn't solve the problem.
I think I have tracked down the problem to Samba but am not sure - When I type in the direct samba link to the server:-
smb://10.10.0.5
The "SMB Mount" screen asks me which share I would like to mount. This works without a problem. I create a shortcut to the share. This also works until I reboot, then the problem reoccurs!
I think I need to reinstall Samba, or update the Samba software?
Does anyone have any thoughts,
John
G5 Mac OS X (10.3.9)

And with that dislcaimer...
What sort of settings do you have checked in your Directory Access > Services panel? That is, do you have SMB turned on?
Also, I would make sure that your server and computer's clocks are showing the exact same times-- just in case there is a synchronization issue.
Our Macs have had similar, but not identical, problems in the past.

Multiple severe performance issues under Windows

I own a Macbook Pro, and have used it happily for around a year. However, the hard drive was too small (no idea why I decided to go for the 80), and my music library kept growing. At the same time, I needed a Windows machine for various other purposes, so I bought a Dell with Vista. I successfully transferred all of my music over to it, and downloaded iTunes. It installed fine, and all of my music showed up, and plays.
Here are the problems. Compared to OS X, iTunes on Windows *****. Unbelievably. It's incredibly sluggish (even basic things like scrolling through your library - smooth as silk on the Mac, but choppy on Windows. Resizing the window doesn't work well, either), and it has to have at least a few major memory leaks.
I'll give you some specifics.
Acting "Sluggish"
- Scrolling through my library (with either the scroll wheel of the mouse or the scrollbar on the right) is very choppy. This is not the case with any other application on my computer - scrolling through a list of entries is smooth and works well.
- Resizing the window frequently doesn't work. I'll grab the corner, and move the mouse over to another area. The mouse will be on a different part of the screen, but the iTunes window will not have resized at all. If I move the mouse, the window then resizes to where the mouse last was. In other words, if I want to resize the window, I have to grab the corner, drag to another size that I think I want, and then move the mouse a little to get it to go. This animation is also very choppy.
- Coverflow is very slow and moves at a very low framerate, fullscreen or otherwise.
- Oftentimes, the first keystroke (or two) will be completely ignored. So, for example, I'll hit Ctrl+L to get to the currently playing song, and have to press it 2 or 3 times in order for it to have any effect.
Memory Issues
- When I start iTunes (in the smallest window possible), it takes around 56 MB of memory, not playing anything. Once I start to play a song, it jumps a little, but ultimately doesn't change that much (now it's at 60 MB instead). I resized the window to be on most of the screen, and it's now at 66. Scrolling through my library on List View, while slow and choppy, doesn't take up any significant amount of memory. However, as soon as I change to either the "grouped with artwork" option or coverflow, bad things start happening.
- Grouped with Artwork: At the beginning, iTunes is taking up 70 MB of memory. Every time I hit Page Down, another 3-4 MB of memory is added. This memory is never released. So now, having scrolled down from the top a little, iTunes is now sitting at twice what it was at the beginning, or 145 MB. It's now taking up more memory than Firefox.
- Coverflow: Starting out at 145 MB from the earlier view, switching to coverflow immediately makes the memory jump to 170 MB. When I scroll through the albums, the memory then jumps anywhere from 40 - 50 MB. After a bit of clicking, iTunes is now taking up 1,106 MB of memory.
I minimize iTunes, and 1 MB of memory is freed. iTunes is now at 1,105 MB.
Moving out of CoverFlow view does a good job at cutting some memory use, but it's still at 540 MB. And at this point, I'm back to where I started (in terms of what iTune's doing: list mode, small window, not playing), only at 9 times the memory use. As far as I know, there's no way to reclaim that memory.
Various Issues
- iTunes will frequently disregard the first or even second keystroke, as mentioned above.
- This scenario is a little harder to describe, but I'll do my best. iTunes is the foremost application. The focus is on song panel (the main part), so that pressing the Up and Down arrow keys cause the "currently selected" blue background thing behind a song to move up or down, enter plays the currently selected song, etc. I Alt-Tab to another application, and then Alt-Tab back. It looks like I'm in the same situation as before (the currently selected song is blue, instead of grey), but the up and down keystrokes do nothing. I'm apparently in a different section of iTunes. Pressing Tab brings me to the left panel of iTunes - the Music / Movies / Podcasts / Ringtones / etc. part, but the up and down keys don't do anything there either. Tabbing again takes me to the search field, and that works. And tabbing once more brings me back to where I should have been as soon as I Alt-Tabbed back to iTunes.
- A variant situation: focus is as described at the beginning, and I Alt-Tab out and back into iTunes. Again, the up and down keys don't work, but then if I press Shift + Tab (to go to the previous field), it starts working again.
This issue is much more of a pain than it sounds. If I'm in iTunes, and I'm chatting online, for example, I might need to switch out quickly to type a line in, and then switch back, but the workflow has been completely disrupted because I can't navigate with the keyboard anymore.
- When editing a song title in iTunes, I select it first, and then press F2. This causes the title to become a "rename" field, which works mostly fine. With one exception. Generally, in these fields, you edit the title to your heart's desire, and then press Enter to signify that you are done. However, in iTunes, if I have a song title "blowin' in the wind", and I want to capitalize it, I'll hit F2, and then move the cursor over to the beginning of the title (in other words, to right before the "b"). My goal is to delete the lowercase b, and replace it with an uppercase B. So I press Delete, and then type B. However, as soon as I press the Delete key, iTunes deletes the character, and then closes the rename field. It's as though I pressed Delete and then Enter. If I then type B, I'm taken the first song starting with a B, which is not what I want at all.
- iTunes doesn't work with Vista's window preview (Aero interface, Alt+Tab or hovering over the program in the tray at the bottom) when it's minimized.
- When I have iTunes on in the background, and plug in an iPod, it all works fine, except for when I bring the window up. For whatever reason, iTunes doesn't repaint the window right at all. It's a horrific mixture of whatever songs were in the list view before and the iPod options.
I'm sure I have more issues, but those are the ones that come to the top of my head. Note that I have none of these problems in iTunes on the Mac.
Apple, if you're going to release software for Windows, please make it work.

Wup.sys / startup issue w/ Windows 2000

I've been running iTunes on my laptop for years. I'm shifting to a desktop, with a much larger hard drive, so I convert my CD collection (and shop more at the iTunes store, heh).
But when I install iTunes, startup hangs about 75% of the way across the blue/white status bar (above the "t" in Microsoft). Using F8 for command line startup, startup freezes just after "wup.sys". Many many many forums discuss purported wup.sys problems (including incompatability with USB, iTunes, and more), with the only conclusion being that wup.sys is simply the last thing to load before the registry, and that anything that upset the registry would cause startup to freeze when the registry loads.
Soooo... I can use "last known good configuration" (LKGC) to get back into Windows. I can then successfully uninstall iTunes, although that's not necessary - startup proceeds on the LKGC without a hitch. But the LKGC misses the registry settings that iTunes made. And if I run (rather than uninstalling) iTunes, I get a warning that the registry settings for importing and burning CDs aren't there and that I need to reinstall iTunes. Doing so only reintroduces the mysterious startup freeze so oft associated with (and blamed on) wup.sys. Doing LKGC again, I can run iTunes, with apparently full functionality except for importing and burning - which I haven't tried, but am timid about without further advice.
Given the hundreds of posts, and dozens of forums, mentioning wup, many of them citing iTunes, surely I'm not the only one with this problem. And yet, despite hours of googling, off and on over the course of three weeks, I ain't found an answer.
(BTW, yes, I have the updated Windows install engine, Service Pack 4, newest version of iTunes, Windows Update runs daily, logging in as administrator, disabling virus-protection and closing all other programs, etc etc.)
Thanks,
Ellis

Woo-hoot/___sbsstatic___/migration-images/migration-img-not-avail.png It wouldnt have occurred to me that installing those drivers separately was possible, much less safe - but IT WORKED/___sbsstatic___/migration-images/migration-img-not-avail.png
iTunes started and ran fine (no warning about registry issues for ripping/burning), and reboot went fine (no hanging, no errors).
I guess that means that the drivers (and related registry settings) themselves aren't the issue (i can rip and burn fine now), just the way they're implemented in the iTunes install executable?
I did get an "A specified file, path, or program could not be found." warning at startup the first time, but with nothing in the dialog box's header or body to indicate what it's talking about, and no discernable effects, good or bad; and it only happened once - but I'll mention it here for the record, in case this word-around introduced something incomplete and/or in case someone reworks the iTunes installer.
THANK YOU/___sbsstatic___/migration-images/migration-img-not-avail.png Now, someone please relay this to the installer team. Something ain't right with it, and lots of folks could benefit by this fix - and there are almost certainly other people who gave up on iTunes or (worse) their computers when they encountered this issue.

Install Problems under Windows 2000

I have recently upgraded my machine from WinNT4 SP6 to Windows 2000 Professional, and now I cannot install JDeveloper. I have tried 3.1, 3.2 and 3.2.2 and all of them hang at different stages during the installation. There is no error message, the install application just stops responding.

I haven't had problems with any other products installing. I have tried installing JDeveloper 3.2.2 with the bare minimum of components as well as trying the typical installation and nothing seems to work, Im not running anything in the background. The system is a HP Kayak XM600 with an intel PIII 800Mhz 256Mb RAM and an ELSA Synergy graphics card. Someone else I know tried to install it on a Dell machine with a different setup, but under Win2000 Professional, and the install failed on them as well.
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by JDev TEam (Laura):

Hi shubhu,
I just analyzed your partial Thread Dump data, the problem is that the ajax4jsf framework ResponseWriterContentHandler triggers internally a new instance of the DocumentBuilderFactory; every time; triggering heavy IO contention because of Class loader / JAR file search operations.
Too many of these IO operations under heavy load will create excessive contention and severe performance degradation; regardless of the OS you are running your JVM on.
Please review the link below and see if this is related to your problem.. This is a known issue in JBOSS JIRA when using RichFaces / ajaxJSF.

ITunes on Windows 7 performance issues - slow and hangs

Is there any way to improve performance of iTunes running on Windows 7?
It has always been slow with lots of application hangs and stalls that will resolve themselves if you wait for iTunes to catch up, but I find it incredibly frustrating.
For example, when iTunes starts and if it is checking podcasts, the entire application is unresponsive until it finishes checking and refreshing podcasts.
Alternately, when viewing my iPad Air and looking at the list of apps installed via iTunes it can take 30 seconds before iTunes responds.
Considering that this is running on a system with a quad-core Haswell processor at 3.2Ghz, 16GB of RAM and Windows 7 x64 it is pretty unacceptable.
The efficiency at which iTunes operates is just appalling. I can run Adobe Photoshop and many more memory hungry and processor intensive applications than iTunes and get better performance than what I see in iTunes.
This is not specific to my system either. All of my family members have iPhones and their own computers and this performance issue exists on every computer I have ever run iTunes on.
Is there any way to manually tune performance because this is pretty crappy. It's been bugging me for years, but today just kind of feels like the last straw.

I guess the answer is, "It's terribad, live with it"

Compatibility Issues with CS2 and Windows 2000 XP??? This is supposed to be THE one operating system CS2 DOES WORK ON? Can someone help - I really need my CS2 back! Thanks.

HELP! Years ago - SEVEN to be exact- I PURCHASED Adobe CS2 and used it extensively. Then I was in an accident that took five years to recover from. After my recovery I tried to get back to using my Adobe products only to find that Adobe was discouraging use of CS2 and since I OWN a LICENSE and that was the LAST version I used I wanted to begin again with a version I am familiar with. Many months later, apparently I wasn't the only one who wanted to KEEP USING CS2 and now Adobe has made it possible to download this version for PC and MAC, BUT due to OS compatibility issues Adobe continues to discourage downloading and use. HERE'S THE THING: I have the SAME SYSTEM running the SAME OS as when I first PURCHASED IT. I have downloaded the EXACT SAME VERSION of CS2. It installs fine. But I cannot OPEN the application and the troubleshooter reports there are "COMPATIBILITY ISSUES". WHY?!?!?!?!?
I'm on a PC running Windows 2000 XP. I OWN a LICENSE for Adobe CS2 and it used to run on this very same machine. I had to re-format my system two years ago so it has much more free space but when I try to OPEN the application it won't run. When I run the Windows Troubleshooter it reports system compatibility issues?! Can anyone advise me what to try now??? Thank you.

Yes, I have. My system was completely cleaned of everything and I'm just now RE-INSTALLING CS2 for Windows2000 XP from the Adobe site that gives you versions to select for your OS. I have successfully downloaded disks 1,2 and 3 and I can INSTALL disks 1 and 2, but it FAILS at disk 3. I REALLY need to resolve this today because I need to submit some work by tomorrow and the troubleshooting isn't helping!
Can you advise anything else . . . anyone? Thank you!

Windows 2000 connector Patch issue (Patch ID: 8318738)

Hi,
We have applied the latest Windows 2000 connector Patch on our DEV environment.
While trying to provision the Windows resource (the user’s home network shared folder), effectively there is some permissions issue that is encountered while executing in the DLL and it effectively causes some page fault that prompts the OS to kill the process and the OC4J instance is restarted.

------------------------------------ Program End ------------------------------------
Compiled the above code in Java 6 and ran the above program in JRE 6 and JRE 7. JRE 7 takes approximately 10 times more time than JRE 6. This leads to a huge performance issue in our project.
I ran it 5 times in each JRE versions and below are the test results,
When run in JRE 6
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 18
Total Time Taken For Ten Call: 81
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 17
Total Time Taken For Ten Call: 80
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 19
Total Time Taken For Ten Call: 80
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 18
Total Time Taken For Ten Call: 79
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 18
Total Time Taken For Ten Call: 80
When run in JRE 7
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 98
Total Time Taken For Ten Call: 891
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 100
Total Time Taken For Ten Call: 869
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 98
Total Time Taken For Ten Call: 859
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 99
Total Time Taken For Ten Call: 871
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 99
Total Time Taken For Ten Call: 888
Is there any other way to optimize the performance in JRE 7 internally, Can the above issue considered as a bug with Windows JRE 7? Can I go and submit a bug for this?

I have simplified the program to point out the exact issue. In the actual usage we need to know immediately or whenever there is an ip change, it might be because of the change in ip to same nic card or when connected to a network via any of the nic card (wifi enabled, etc).
Overall it is particularly important to as we used to get the NetworkInterfaces for every features. As a result of this, 60 feature which gets executed roughly around .5 milliseconds in java6, now consumes almost 6-10 seconds in java 7.
Also in our client server application, where client queries for NetworkInterfaces and further sends a requests to the server where we have to support at least 100 transaction per seconds(TPS for complete client-server throughput), with 100's of client systems querying for its own NetworkInterface is consuming time and certainly reduces the overall throughput.
Currently I am more inclined to cache it and refresh in a separate thread internally, but certainly I wanted to avoid it because the throughput will be less for the first request and especially when it works perfectly fine with java6.

Windows 7 Enterprise login performance issue RODC site

Hi,
We are deploying windows 7 enterprise to all our computers in our domain and we didn't have any performance issue on any site with Full DC. Now we are facing a problem with our multiple sites with RODC but only with new deployed windows 7 (WinXp is not having
this slow login problem). The problem is very strange. Whatever a user start a session on a desktop or laptop with Windows 7, wireless or cabled, when the user enter his credential and press the "validation arrow" next to the password nothing happen
(well it look like nothing happen). After 5 to 10 minutes at this logon screen, we finally see the logon process start applying domain policy, preparing the desktop etc etc and this take less then 10 seconds but remember, we just wait 5 to 10 minutes until
the computer process the "process my log in" botton. Sometime, the CTRL+ALT+DEL screen come back and when we press them we got nothing, we have to wait for the "logon" to occur before doing anything else with the computer.
I've looked to many way to solve this but for now nothing worked.

Hi,
Sorry for my dilatory reply. How about using a same user account to log on XP computer? Will it logon fast?
Have you tried to add a user account into Allowed RODC Password Replication Group for test? This problem probably caused by the password authentication problem In RODC host.
For further investigation, you can try to use Network Manitor at RODC host to capture package of client machine authenticate to a domain controller.
The blog about Understanding "Read Only Domain Controller" authentication
may be helpful.
After the above steps, We can narrow the cause of this problem.
If problem persists, this problem may caused by Windows 7 Client performance. Generally speaking, the problem like this most probably caused by sercurity application problem. You can try to disable or uninstall security application temportaily for test.
If there is any progress, please feel free let us know.

We can extract using the GUI, select the patch and right click Winzip and extract
Why we are not able to extract from command prompt?
Any help would be greately appreciated.

ITunes 7.3.2.6 and Windows Vista Performance Issues

I recently purchased an 80GB iPod, and downloaded iTunes promptly, disregarding all the negative attention about how "iTunes crashes your computer" or "iTunes kills Windows". So far, the only real problem I've had with iTunes is the amazingly poor performance it has on my computer. When iTunes is minimized to the system tray, or compressed into Mini Player mode, it runs better, but not well.
Running in the full mode, the player bogs down my computer substantially. Knowing my laptop isn't a powerhouse, I expected a slight bit of slowdown, since there is some evident with QuickTime.
UPDATE: I've just stumbled across something. Apparently, wiggling my mouse over the iTunes program, iTunes runs about two or three times faster. The moment I stop moving the mouse cursor over the window, the speeds return to slow. It seems to only do this during the "Processing Album Artwork" phase. Bizarre? Very. Any explanations?
I find this to be very annoying, especially when syncing. Syncing my library (which is about five or six gigabytes) takes an amazingly long time. Are there any workarounds, registry hacks, or anything else that can be done? Thanks!

Do you have ReadyBoost enabled on the PC? If so, by way of experiment, try disabling that as per the instructions from the following document:
Troubleshooting iTunes for Windows Vista video playback performance issues
... any help at all with the performance issues?
