OAS is slow when accessing on same machine

I have OAS 4.0.8.1 installed on an NT machine (4.0 sp6) on our network. When it serves pages to a browser on the same machine the response time is very slow (5-6 seconds).
The pages that I'm accessing are fine. When using a browser on another machine on the network the response is less than one second.
Memory doesn't seem to be the problem (256MB).
I've also tried modifying the Hosts file in \\winnt\system32\drivers\etc, with seemingly no affect.
The database accessed by OAS is 8.1.5 on another NT.
Any ideas?
Thanks,
Eric

Thought I would reply to my own post in case someone wants to know the answer.
We ended up solving the problem by upgrading to OAS 4.0.8.2. Oracle agreed that this was a bug in 4.0.8.1 and would have a patch available (sorry - don't have the number). Regardless, we found that upgrading was easier.

Mac Mini slow when accessing hd - NVidia MCP79 SATA Driver Problem?

I bought a Mac Mini (Early 2009) a while ago. Unfortunately i have a problem concerning speed and responseability which i couldnt solve even with a lot of googleing.
I noticed that problem first time when i tried to play a video file from hd. The video does not play as smooth as it should. It stutters from time to time. It is like a short interruption. The picture freezes for half a second and replays the lost frames very fast after that. These freezes do not occure periodically. It seems to appear randomly. The wierd thing is that the cpu usage is very low and there is enough free ram and disk space.
So i think its not a ressource problem. I noticed that these freezes do not only affect video playback. The whole system is kind of unresponsive. And thats the the case if there is some sort of hd or dvd access. When i try to copy a huge file these freezes are increasing rapidly. The more hd access the more the system is unresponsive and cannot be used anymore.
All these effects reminded me of a faulty dma/udma setting on windows machines. So i tried to check the transfer mode for my macs hd controler. But i didnt find any place where to check that. And i dont really think it is running in pio mode because that would result in a high cpu usage.
I played around a little bit to understand whats going on. So this is what i found out:
When i play a video from the hd its stuttering. It increases if i copy a file from or to the hd. Copying a file from the dvd-rom increases the effect as well. It is not influenced by a copy from AND to an external usb hd. And the whole effects do not appear under Windows Vista no matter how much i acces the hd.
So i come to the conclusion that there must be something wrong with the SATA controler driver which is a NVidia MCP79. Unfortunately i have no idea what i can do to solve this problem. And i didnt find any advice or something in the internet.
So i would appreciate any suggestions.

Ok, I think I was jumping to conclusion. Disabling journaling didnt remove the problem. It just seemed so because my problem is much less distinct with Leopard. Bad luck I guess.
kmac1036, to answer your questions. For sure I dont have warranty anymore. Maybee I should have posted that I upgraded my Mac to 3 GB RAM. Furthermore I replaced the original Hitachi HD with a Western Digital 500 GB model.
Somehow that may be connected to my problem. I've read that many people have problems with the WD HD and those beachballing issues with SN. (I do so too)
But my performance problem when accessing the HD did also exist with the Hitachi. In fact the Mini was extremly slow with the original 1 GB RAM. I think putting some additional memory into the machine helped because it reduced hd accesses.
Ok, I am not an expert. But if I had to guess I would say the following seems to happen. There may be an operation in the hd driver that takes longer than it should. Because of that it maintains cpu cycles and prevents the kernel to continue scheduling. That would explain why the freezes are not connected to a high cpu usage and why the systems seems to catch up things after the freeze very fast.

Custom WCF app hosted in SharePoint _Layouts errors when access form client machine.

Hello, I have a very strange behavior of the WCF dotnet application hosted in SharePoint server. When I run the application on SharePoint server by accessing
http://SPSServer/_layouts/WCFCustApp loads correctly and executs all functionalities. However from the client machine when I access the same application, it throws below error:

Both I verified and none of those helped to resolve the issue. Will you please let me know if anyone else has encountered this problem?
I have noticed the WCF project has one web.config and it does not take from it when the application is deployed to SharePoint site collection. I made sure the sharepoint web.config file has all tcpip and other web service configurations. It works great on the
server and just failed to run from client machine :(
Experts any other solutions that you might have experienced?
Thanks

YouTube extremely slow when accessed using WiFi

I find that, in the last day or so, accessing YouTube has become painfully slow when using WiFi. It was working fine earlier in the week.
EDGE connections have faster downloads but the quality is really poor.
Anyone with similar problems? Any explanations as to what might be causing this?
Thanks,
Anil

Bump to this, I am also experience the same issues as well with Youtube being slow on WiFi compared to the horrific version on EDGE. I would think this to be a Router issue, but I have yet to test it out by shutting down all other applications that access the router as well as other computers that use the router.

BO slow when accessing reports through the web but not with a installed client.

Hi
We have installed BO 4.0 SP08 in a virtual machine with 32 RAM and 8 CPU processors. We have divided the APS in a number of instance with different services. We have also 8 Web Intelligence Processing servers.
The application is slow when trying to create or view a report from the web browser (ie or chrome). If we use the installed Web Rich Client on a machine, then it works fine.
Does anyone knows why?
thanks
Teresa

Any ideas??
I don’t know, but whatever it is, it’s preventing you from creating complete sentences.
Run the Apple Hardware Test as described on page 101 of your owner’s manual to see if it detects any problems.

Safari 4 slow when accessing .htaccess protected sites

Hi, I just found Safari 4 to be deadly slow, when I access a site which uses apache "Basic" authentication. After first accesss I'm promted to enter username and password and everything works besides it takes up to 10 sec to load a single page. When I disable authentication for the site everything is nice again (load times per page below one sec).
Ideas anyone? Thx a lot.

Also, i have this form that does the authentication through an ajax request, so you don't get that pop up window. In previous versions this work fine, but now it pops up the window after logging in...
I could not find any explanation...
Any idea someone?
cheers.

845PE very slow when accessing memory

I have a P4 3.0GHZ (1.5GHZ) on a P845PE MAX board that runs very slowly (20 minutes+) on memory intensive operations, although it is only using half the available physical memory. If I run exactly the same operation on another machine running a P4 1.8GHZ it takes about a minute.
My machine
P845PE MAX
P4 3.0 GHZ running at 400 = 1.5GHZ
Win98(SE)
AMIBIOS 3.4 (default settings)
Radeon 7000 AGP
2 Western Digital Hard drives (7,200rpm)
512MB DDR PC2700
PCI Modem
300W PSU(will need to check as maybe the 12V and 5V rails are 140W)
Any suggestions

Installed a new PSU - No change still slow.
My estimate is that the CPU is fast when I do a Virus Scan it takes 18 minutes for about 10GB.
Now also tried a Celeron 2.4GHz, 128KB, Bus Speed 400MHz still slow on memory intensive operations. Virus scan takes 32 minutes.
Tested the memory using a tool that's been mentioned on this site Passed 5 times.
In Bios AMI 3.4 CPU L1+L2 Cache set to WriteBack.
Can't upgrade the Bios fails to boot up if I flash with 3.9 or 3.4 always have to recover, very scary!
As I've said running on Win98(SE) - could this be a problem on MyComputer it states the processor is x86 Family 15 Model 2 Stepping 9.
Thanks in anticipation

ODI Studio Slow when accessed via Citrix

Hi !
I login to ODI via Citrix Server. My ODI is installed on Citrix machine and my master repository and my work repository at a database which is not installed on the citrix machine.
When i see the solution that is provided earlier in this thread to have the work repository setup locally - does this mean that the work repository needs to be setup on a database on citrix where my ODI is installed?
Please validate and provide further inputs as to what are the other ways to resolve this issue.
Thanks & Regards,
Prerna

Hi Phanikanth
Yes i did, the problem is when a user is created and if i logged in using that user ODI studio is very slow, but if i logged in using supervisor it works absolutely fine.

SocketPermission error in applet when accessing the same domain

Hello, my applet downloads the contents of an URI from the same domain, using a relative URI. This should be AFAIK an unprivileged operation and should be always allowed, even for unsigned applets, such as mine.
(In contrast to accessing URIs from a different domain, which requires the applet to be signed or self-signed & confirmed).
Indeed, the applet works perfectly under Windows, both with MSIE+Microsoft JVM, MSIE+Sun JVM and SeaMonkey+Sun JVM and Opera+Sun JVM.
In contrast, under my Gentoo Linux, in SeaMonkey+Sun JVM this doesn't work. Under both Windows & Linux the Sun JVM version is 1.6.0, SeaMonkey version 1.1.7, Java plugin "Java(TM) Plug-in 1.6.0_03-b05". - Everything is emerged from the current stable Portage tree (ebuilds www-client/seamonkey [1.1.7], virtual/jre, dev-java/sun-jdk [1.6.0.03], plus I created a symlink 'libjavaplugin_oji.so' in directory '/usr/lib/seamonkey/plugins' pointing to '/usr/lib/jvm/sun-jdk-1.6/jre/plugin/i386/ns7/libjavaplugin_oji.so'
I have made no changes to my java.policy file. [Yet it seems that such rule as "allow URI access in the same domain" cannot be expressed in this file's language]
The error message I get is exactly what I would get have I tried to access an URI from a different domain. [See below].
Googling as well as searching Sun's forums failed to give an answer. Has anyone have had similar problems? Is it more likely to be just a configuration/Gentoo problem, a more general problem, or perhaps the problem is just between the monitor and the keyboard?
Any help is most welcome. TIA,
Jiri Svoboda

Thank you for contacting us to let us know you are experiencing a problem.   Yes, we have addressed the issues we were experiencing earlier.
I believe the problem you are facing is bcause you must use the original user ID you provisioned with your Xfinity Home account. Unfortunately, we only support a single user ID per account on the mobile applications today. We do plan to change this in the future.
I will private message you with the user ID to try on your mobile account.

How to invalidate old sessions when new user access appl on same machine

hi all,
I am using Mozilla browser to access my web application.User one access my application using his credentials .but i left that browser open.after that I am opening the another Mozilla window and accessing my application using different credentials ex:user2 credentials .user 2 also can access my application.but when i open the first browser ..am automatically getting second user session.how can we avoid this problem.
Application is using session identifier(jSessionID) as the URL parameter for session management.
is it possible to invalidate the old session when new user access on same machine.
thanks,
Vishnu

Either you explained it the wrong way (or I interpreted it the wrong way), or there's huge bug in your login/logout logic. After opening another window inside the same session, you should still be logged in as the first user.

Can CS3.3 & CS4 Master play nice installed on same machine at same time?

First off here are the specs on my desktop and laptop:
Desktop:
Mac Pro running OSX 10.5.6 - 2 x 3 GHz Dual-Core - 6 GB RAM - CS3.3 Master Collection currently installed
Laptop:
MacBook Pro running OSX 10.5.6 - 2.4 GHZ Intel Core 2 Duo - 2 GB RAM - CS3.3 Master Collection currently installed
I recently received all the install discs for CS4. Spent the last hour researching how CS3 and CS4 play together when installed on same machine at same time. I haven't found anything that addresses my questions, thus the post.
At present, not enough of my work colleagues have CS4, so if I install CS4 and uninstall CS3 - and need to pass a file on to someone who doesn't have CS4, they can't open it in CS3.
Also, I use AfterEffects with many 3rd party plugins. Until I can verify that CS4 plays nice with these plugins, I can't afford to uninstall AfterEffects CS3. Obviously, I need to keep CS3 up and running on my desktop and laptop.
But now that I have CS4 ready to install, I of course want to start using it and learning the new features.
Has anyone successfully been able to install CS4 Master apps on a machine similar to either my desktop or laptop specs and have CS3.3 Master apps continue to work properly?
I trust Adobe takes these types of version overlaps seriously and plans for them since people want to try out or start using the newest version but ensure there is a sufficient overlap period before uninstalling the older versions.
Thanks for your comments
jslicer

j,
Your old apps will work. But the new versions will be the defaults. You can touch your files to the old application to launch it or launch the old application first, and then open files "normally".
If you need to ensure compatibility with older versions on other machines, don't delete the old apps. Or be prepared to save back to the old version before handing off the files. Note that InDesign cannot save back more than one version and in general, any features used that are new to the new apps will not be recognized when those files are saved back.

Why yahoo/gmail retrieval and facebook app so so slow when in WIFI. But using the internet to check for emails and facebook is fast using the same WIFI connection??

Why yahoo/gmail retrieval and facebook app so so slow when in WIFI. But using the internet to check for emails and facebook is fast using the same WIFI connection??

Hi SandyS_VZW,
Yes tried resetting the wifi connection and problem still persist.
Here it is...to make it clear. Connected thru the same wifi at home...
-> emails (yahoo/gmail) and facebook WEBSITES are working fine and fast when using/accessing thru a browser (chrome/samsung browser) - no problem with this.
-> emails (yahoo/gmail) and facebook APP is soooooo sloooww (thru the App). Slow I mean comparing it to using their browser/websites... news feeds/emails refreshing so quickly but not when using the APP installed in Samsung Galaxy Note 4. Slow like - It will take around 5-10minutes just to get your emails and news feed refreshed.
THIS HAPPENS ONLY WHEN CONNECTED THRU A WIFI which has a speed of 10-20mb. It is not happening when connected to the network data/plan.
My wife has the same Samsung Galaxy Note 4 (coming from different provider at&t) - same setup (emails, fb app), same wifi connection, but she's not experiencing anything like it.
Not sure why, I dont want to believe that while connected to a WIFI, Verizon is restricting anything and ******* me off to make me switch to my data plan connection everytime - which is Unfair!
Was there a known issue similar about this case?
thanks,

Certificate validation when server is the same machine as client

Hi guys i realize this is the most talked question about jsse, the validation of local certificates.
I found a 2001 o'reilly page where they explain what is jsse and gives a complete tutorial of it.
It comes with a sample secure http server and browser, and when i try to connect to the server with that browser it bombs out with the "couldn't find trusted certificate"
Having read some posts here and googled around i found out that this sometimes happens because the name on the signed certificate does not match the url accessed from the server.
So, if the server and client is on the same machine (127.0.0.1) and my machine name is FJL, can someone explain me how should i run the keytool?
This is what i have been using:
keytool -genkey -keystore certs -keyalg rsa -alias espectro -storepass serverkspw -keypass serverpw
The keytool then prompted me for information to put into the certificate. My answers are shown in bold.

the web server is found here http://www.onjava.com/pub/a/onjava/2001/05/03/java_security.html?page=1 to page=5 or so

You may wonder what happens when you run SecureBrowser againstSecureServer. It doesn't work. That's because SecureBrowser won't acceptSecureServer's phony certificate. However, we can trick SecureBrowser into accepting SecureServer's certificate. Here's how:
So i use the keytool again to do what it is suggested:
keytool -export -keystore certs -alias espectro -file server.cer
then:
keytool -import -keystore jssecacerts -alias espectro -file server.cer
the jssecacerts file is located on the dir where i did the keytool thing, so i copy it to c:\j2sdk1.4.1_02\jre\lib\security
and finally i try to connect to the secure httpserver found on that url with the secure browser found there too and i get the "couldn't find trusted certificate"
could someone please explain me how to fix it? the article is kind of old and lists some properties which i haven't been able to find, along with some .jar (the article is dated before java 1.4 was available) and maybe i am doing something wrong.
Thanks in advance!

Ok, indeed, when keytool asks me about my name, i tried it with my machine name and now it works.

Cannot open 2 Virtual Machines at the same time to access the same Database

Folks,
Hello.
I am installing Oracle Database 11gR2 RAC system using 2 Virtual Machines (rac1 and rac2) on the top of VMPlayer 3.
The VM rac1 and rac2 run correctly when one of them is shutdown.
Their locations are F:\VM_RAC\rac1 and F:\VM_RAC\rac2.
While rac2 is running, I open rac1. But this error message comes up:
Error: "Cannot open the disk F:\VM_RAC\sharerac\asm1.vmdk or one of snapshot disks it depends on. Reason: failed to lock the file."
While rac1 is running, I open rac2. But this error message comes up:
Error: "Cannot open the disk F:\VM_RAC\sharerac\asm1.vmdk or one of snapshot disks it depends on. Reason: failed to lock the file."
The 2 error messages are the same. This means I cannot open 2 VMs rac1 and rac2 at the same time. When we run RAC system, we have to open 2 machines or more than 2 machines at the same time so that all machines can access the same Database Server.
My question is:
Can any folk tell me how to have rac1 and rac2 run at the same time ?
Thanks.

You need to disable disk locking, which ordinarily is performed by the first VM to prevent any other VMs from corrupting your vmdk files via uncoordinated writes. You will have to shutdown both of your VMs and edit the *.vmx flat file for each, adding lines like the following (settings taken from workstation 6, but should be nearly identical settings for VM Player 3.x):
http://crosbysite.blogspot.com/2007/10/clustering-in-vmware-workstation-6.html
scsi1.sharedbus = "Virtual"
disk.locking = "false"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
A few comments:
- your shared disks (scsi1) must be on a separate virtual scsi bus than the boot disk (scsi0), to allow setting the sharedbus flag as seen above.
- you must also ensure the cache parameters and unsynced writes settings are set to guarantee that all IO is immediately flushed to the vmdk file so the other VM can immediately access the latest version of data.

OAS is slow when accessing on same machine
