Application selects is relatively slow in some times
Dear Friends,
Some selects of our application is relatively slow in some times (When database is slow) . But same selects shown good performance in most of the time. Database is always not slow in peak hours. I feel there would be insufficient space in Execution plan area or Sort area.
Can you give me how i change these settings in my database. and where these execution plan and sort area located.
regards
upul Indika.
Hi,
Try to check for the SGA size in your database. Accordingly increase the shared pool size and the buffer cache size which wil generally improve the performance of the queries. Make sure you donot increase the sixe of shared pool in excess of the size of the SGA.
Regards
Bharath

SharePoint Site Very Slow and some time Request Timed Out
Hi All
I have many Web Application is running in SharePoint Farm. Since yesterday one of the web application started responding very slow. It takes 5 to 6 mins to load the page. Some time i received request timed out error message. But all other web applications
are working good.
I increased executionTimeout value, stall it slow / not responding.
Please let us know if you have come across this issues or any suggestion from your end to resolve this issue.
Thanks in Advance - Guru
Cheers, Guruprasadi would recommend enable the developer dashboard on the web app and check which task is consuming the more time i.e. webpart, query to database etc.
also any change to web app since the issue started, any new webpart added to the page, any solution deployed or something else.
also did you try to recycle the app pool of the web applications?
how many wfe in the farm?
Please remember to mark your question as answered &Vote helpful,if this solves/helps your problem. ****************************************************************************************** Thanks -WS MCITP(SharePoint 2010, 2013) Blog: http://wscheema.com/blog -

Handling anything gets extremely slow after some time
I'm having a strange issue with CS5. Without any apparent reason, the file I am editting becomes very slow with simple actions. For example, moving a (random) object around. Using the arrow keys, it takes every move about a second to complete... there is a lot of weirdness surrounding this, so i'll try to give as much input as I can.
- before this issue comes up, everything is working fine
- there is only line art in the file, simple line art for that matter (squares, straight lines, text).
- if this happens, and i copy paste everyting in a new file, it is working fine again for a random amount of time, until it gets stuck in slow mode again
- Outline mode, has no effect on the delay
- Turned off all effects (only drop shadows) and had no effect
- The file size is around 2,5MB
- Tried tweaking all the settings i could think off (resolution, anti-aliasing, etc), which had no effect.
- Turning off thumbnails in layers has no effect
- sometimes, re-opening the file helps, sometimes it doesn't...
- If the problem is "on", whenever i nudge an object, my cpu shoots to 100%.
- I'm running on a 2010 Macbook Pro (4gb ram), so that shouldn't be a problem (I think), it works fine sometimes as well.
- Tried running OSX in 64 bit, didn't make a difference.
- Tried adjusting the "Document Raster Effects Settings". 9 out of 10 times adjusting that makes Illustrator crash (hard), but after getting it adjusted it had no effect.
- Everything has "align to pixel" on, but turning it off has no effect on the delay.
I this just one of the famous Adobe software annoyances I will have to live with? Or does anybody know a cause of this that I might be able to fix?
Cheers and thanks in advance.
BenTnx for the input Mike, the graphic styles, brushes and symbols palettes are filled with the default fresh-install items. So very few in all of them (only swatches has more than 10 items at first glance). All other programs run fine, it's just Illustrator. The cpu spike to 100% of Illustrator (it's process) only happens on a "nudge" action. After that, it goes back to normal. I have no other heavy programs running. I ran the disk utility and repaired some permission errors (according to the log), there were no other errors there.
I am currently working in "normal" mode (the issue is currently gone because i re-opened it a couple of times), but if I happen to go into "slow" mode again, I'll recheck your list just in case. -
OS X Server File Sharing slows down some time around 5 PM
We have a problem with our OS X Server file server becoming sluggish to browse and save files around 5 PM each day.
Historically we had this problem with Mac OS X Server 10.5.8 but it's also seems to be a problem with our new Mac Mini running OS X Server 10.10.
We have one IMAP account on the server that we use to archive about 18000 emails at 12 GB, stored under a number of folders. Could it be this that's causing the problem? I noticed on our 10.5.8 server that it used to process the email and use up gigabits of HD space in the process and then release it all again when it was done. The sluggishness seemed to coincide with this.I know there are options in the policies section of the Open Directory area of Server Admin. Or, in Server App, you can click on Users and then if you click on the little gear thingy under the window displaying the users you can choose Edit Global Password Policy and a drop down window will show the same settings.

Query Designer slows down after working some time with it
Hi all,
the new BEx Query Designer slows down when working some time with it. The longer it remains open, the slower it gets. Especially formula editing slows down extremely.
Did anyone of you encounter the same problem? Do you have an idea, how to fix this. To me it seems as if the Designer allocates more and more RAM and does not free that up.
My version: BI AddOn 7.X, Support Package 13, Revision 467
Kind regards,
PhilippI have seen a similar problem on one of my devices, the 'Samsung A-920'. Every time the system would pop up the 'Will you allow Network Access' screen , the imput from all keypresses from then on would be strangely delayed. It looked like the problem was connected with the switching from my app and the system dialog form. I tried for many many long hours / days to fix this, but just ended up hacking my phone to remove the security questions. After removing the security questions my problem went away.
I don't know if it's an option in your application, but is it possible to do everything using just one Canvas, and not switch between displayables? You may want to do an experiment using a single displayable Canvas, and just change how it draws. I know this will make user input much more complicated, but you may be able to avoid the input delays.
In my case, I think the device wasn't properly releasing / un-registering the input handling from the previous dialogs, so all keypresses still went through the non-current network-security dialog before reaching my app. -

I have Adobe Acrobat 9 Standard on both of my computers.
Some time ago, one crashed my computer and I had to reinstall the operating system and all applications.
After I had installed once Acrobat 9 Sdt in the computer, I wanted to update the software version 9.0.0 update to the same level as it was before the crash and that the other computer has version named 9.5.5.
The system for update from version 9.0.0 does not work at all. "There are no updates" listed in the dialog.
Can you advise how I get my Adobo Acrobat 9 Standard (Version 9.0.0) could be updated to the same level as the computer had before the crash.ftp://ftp.adobe.com/pub/adobe/acrobat/win/9.x/

Actually i am using an off-line form to load very large XML file and using firefox to load that form. But, its taking more time to load and some time the browser crashed. through DOM parsing this XML file to my form. Is there any option to increase DOM handler size in firefox
Thank you for your suggestion. I have a question,
though. If I use a relational database and try to
access it for EACH and EVERY click the user makes,
wouldn't that take much time to populate the page with
data?
Isn't XML store more efficient here? Please reply me.You have the choice of reading a small number of records (10 children per element?) from a database, or parsing multiple megabytes. Reading 10 records from a database should take maybe 100 milliseconds (1/10 of a second). I have written a web application that reads several hundred records and returns them with acceptable response time, and I am no expert. To parse an XML file of many megabytes... you have already tried this, so you know how long it takes, right? If you haven't tried it then you should. It's possible to waste a lot of time considering alternatives -- the term is "analysis paralysis". Speculating on how fast something might be doesn't get you very far. -

BC4j/JSP Application not responding after some time - when deployed on 9ias
Hi,
We are using BC4j/jsp application on 9ias. The application is not responding
after some time. We have installed 9ias on PIII(384MB RAM). We tried to accesses
with 10 users, and server is not responding to BC4J/JSP application.
However the server could able to publish the JSP pages with standerad JDBC code even after that.
many many thanks in advance
nullWhen the application deployed by BC4J/JSP not responding, does the sample JSP application still works? i.e. does any other application respond? Does 1 user respond? Is the database source (JDBC), running Oracle 8.1.7? What is the platform running the database (e.g. local NT database)?

There is currently no mechanism for reducing the connection pool size after a period of high activity. Recently this has been frequently requested and as such will be implemented in the next production release.
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>We have verified this in manual testing. However, when the load tool script exits it doesn't seem to release resources. We know this because we keep seeing our database connections go up and up as more tests are run. Further, we also seem to see more than one connection per "virtual user". For example, when I connect 5 users to the app in manual testing, I get 5 connections. But, when we run a test using the tool, we get 395 database sessions for 200 users. We are having a bit of difficulty understanding why the behavior is different.<HR></BLOCKQUOTE>
Assuming that the you are performing your manual testing against the same instance of the application on which you are performing your load testing, I would assume that the connections are being released to the pool at the end of the request. One possible reason for the approximate 2:1 ratio between connections and virtual users may be BC4J's use of internal connections. What version of BC4J are you using?
BC4J requires an internal connection to support state management and spill to disk. The internal connections are pooled with the transaction connection and only held for the duration of the persistence operation. However, if the web server is very busy then a large number of synchronous persistence requests may be received which would explain the eventual 2:1 ratio in the pool's high water mark.
If the user start times and think times are staggered in order to reduce the incidence of synchronous persistence requests does the ratio of connections to web sessions stabilize at some lower number (i.e. 1.5:1)
