Apex: ever now and then performance degrades

Running Apex 3.2.1 under 11.1.6.0 with EPG. 1GB dedicated to the 11G instance.
Here's the scenario. I'm working away with a sample app (the document manager in this case) in the application builder.
Navigating from page to page in fractions of a second. Then occasionally apex slows down dramatically and can
take 30 seconds or more to server out a page. The server machine itself appears more or less idle.
Worse still this can happen occassionally when running the application. A sudden dramatic slowdown. Try again
later and things are fine.
e.g. Sometimes the app login page appears instantly, other times it will take 20 - 30 seconds.
Any one else experience this ?

Hello:
This issue has been discussed here before. Search for 'shared_servers'.
You want set the database init parameter 'shared_servers' to an appropriate value. You do this by entering the following command from sqlplus as DBA
alter system set shared_servers=10;

FireFox 3.6.23 & 7.0.1 keeps crashing ever now and then, it has already happened atleast 10 times in the last 2 hours or so. No crash report is available. This is going on for the last month or so.

The articles/KB were not helpful in resolving the problem. I am posting this via Opera.

Sorry folks for the late reply.
It seems the problem was with my computer and not with FireFox. Finally, my PC stopped working. Had to get a brand new PC, there seems to be no problem with version 7.0.1 - all is fine so far.

Macbook Air Mid 2013 - Keys freeze up now and then

Hey there, I'm getting a little bit paranoid as I'm wondering if I have a key logger here on my Mavericks installation (10.9.5) on this macbook air; but every now
and then when I'm in Outlook or some Chat client working away - suddenly - some keys stop working ! Like the Delete key does not remove previously typed
letters, or the Letter "A" stops working, then -- after 30 seconds or so it comes back!?
Do other people experience sudden keyboard freezes like this? trackpad works fine.. It's a Mid 2013 with i7 1.7GHz and 8GB of RAM.. so it has no performance
issues, as it runs outlook and some office apps. I patched up Office to the latest version too.
So very weird, my next step is Yosemite and crossing my fingers or the apple store?

Thanks tool, looks great. I will give it a go, i think you are right - it could be some errant IT tool that my company has installed, they have some terrible
Casper suite (which i deactivated), perhaps it's throwing up some Interrupts.. no clue, but Activity Monitor tells me zero.
Thanks again , will be downloading the tool shortly!

I am running Mac OS X Lion on a brand new Mini. Every now and then, my keyboard goes "dead." The mouse still works but can't type. If I restart, everything is fine again. Is there anything that will fix this problem?

I am running Mac OS X Lion on a brand new Mini. Every now and then, my keyboard goes "dead." The mouse still works but I can't type. If I restart, everything is fine again. Is there anything that will fix this problem?
Also, I am trying to connect my Mini from the mini-Displayport to the Displayport of my Dell U2410 monitor. The image is very grainy,even though it is set to the correct resolution: 1920 X 1200 at 60Hz. If I use HDMI to VGA input, the image is much clearer. Is there a way to get the Displayport to work?

I'm having exactly the same keyboard issue. Certainly nothing has ever enhanced my concentration while coding like suddenly becoming unable to type.
I'm seeing a great many devicemgr and rake errors in my system log. I don't know if they're related. How 'bout you?
If you're unfamiliar with the system log…
Open /Applications/Utilities/Console.
If necessary, choose View > Show Log List.
system.log is at the top of the FILES section.
Try searching it for hot words like DEBUG, FATAL, and aborted.
I've found some discussions that would tend to indicate my errors are postGres related – I'm running OS X server.

Airport Express (and Airport Extreme) shuts down every now and then

So here's the deal,
I'm using an Airport Extreme as my base station (internet, printer, external hardrive). I'm also using an airport express (for airtunes) that is set up to join my existing network that I have created with my Airport Extreme.
Every now and then, the Airport express disconnects becomes non responding and starts to flash yellow. The strange thing is that even though my Airport Extreme is still showing a green light - this does not work either.
To resolve this I must unplug both Airports, restart Airport Extreme and then make my network. After that I can restart my Airport Express and join my existing network and everything works well for a day or 2 and then the same happens again.
What is going on? I mean even though I have found a solution it is timeconsuming and not very elegent. I would rather not have disconnections:-)
Look forward to hearing from you bright guys!

I don't think I have a power issue since I have a lot of electronic connected to the same plug and they are working fine.
I have not tried to use the Airport Express alone but I have of course thought about doing that to narrow down the problem.
I don't have inteference.
How do I check if my neighbours are using the same channel?
There are a couple of programs out there. The one I have used is called iStumbler. http://www.macupdate.com/info.php/id/11753. This will show the networks around you and the channels they are using along with other things.
The distance from the AEX to my Airport Express is like 10 inches!
Having an access point close real close to a client will cause some interference itself. Also you had mentioned you had the AEX plugged into the same stip or outlet with other equipment. This can also cause interference and issues.
The firmware is the latest.
I can say that I think I have found a solution though. When I install my Airport Express I hit the "use to extend my network" instead of hitting "join existing wireless network".
It had been working flawlessly ever since (4 days)
I think extending a wireless network is only used if you have 2 AEBS or more. You would use WDS to extend the range when using an AEX but since you are not using it for that you set it right by joining a network.
Thanks

My iphone 3g stays on the apple logo for about 4 minutes then flashes white and goes back to the apple screen, it repeats untill battery is flat, every now and then im lucky enough to get it to turn on but not very often and then it freezes and repeats??

hello my name is kirstie, i updated to firmware 4.2.1 .....my iphone 3g stays on the apple logo for about 4 minutes then flashes white and goes back to the apple screen, it repeats untill battery is flat, every now and then im lucky enough to get it to turn on but not very often and then it freezes and repeats the same problem?? (if i turn the phone off my pressing the two buttons it wont keep rebooting, its only when i leave it after turning it on)
I have reset the phone, full firmware restore, even downgraded back from firmware 4.2.1 to .3.1.3 official by using dfu mode and still doesnt fix.
(i correctly got out of dfu mode after the downgrade)
i can enter dfu mode and recovery, and update through itunes with no problem, but it doesnt fix the problem,
i have searched and found no answer to this problem, every option availible to try that i know of i have tried and failed. i dont care about preserving my content i just want a fix. i have a good understanding how to operate software on a computer and shouldnt be too confused by any advice given, so plz even if the answer is very complex i wish to try anything, please help me to get my iphone working.

Anyone have any suggestions? or is everyone else just as clueless as me !

Every now and then I get about a half second clip of another song

Every now and then I get about a half second clip of another song at the end of a song. If you immediately go back and play the same again, you get the same little burp at the end. But if you play three or four songs and then go back, the little burp is not there. I did a restore on the ipod, and I am still getting the little burps. It only happens maybe once out of every 10 songs played.
Files are MP3's which play fine on the PC in WMP and itunes, and on Dell DJ15, Zune and Sansa MP3 players. Some of the MP3s were ripped from CD using MusicMatch, some recorded off old lps using Creative Go!, and some downloaded so I don't think it is an issue with the MP3s themselves. Since I use several different players, I don't want to maintain a separate AAC library just for the ipod.
Usually the burst is so short that you can't even tell who the artist was, but when I have recognized it was always something very close alphabetically - at the end of a Cream song I got a little Creed, at the end of a Bad Company song I got a little Bachman-Turner Overdrive, at the end of a Led Zeppelin track I got a little Linkin Park.

Does this help?

Using Windows, the only answer would seem to be to re-encode them using iTunes.

Every now and then (every 15 minutes-half an hour or so), my internet fails. It says in the Diagnostics that the internet and server have failed. Happens on my sister's mac as well. Is this our modem?

Hi Patrick,
I'm starting to think it's either an AirPort card issue or something to do with the Mac OS. I have stopped using wireless as much as possible in my home (have wired up several new Ethernet outlets), and it sure is nice having Internet run at the speed it's supposed to all the time, and with no drops. Might be something to consider.
In the meantime:
Open System Preferences > Network > select AirPort > click on Advanced > TCP/IP > Configure IPv6 > Off > OK > Apply > Turn AirPort Off > Turn AirPort On
Open System Preferences > Network > select Ethernet > click on Advanced > TCP/IP > Configure IPv6 > Off > OK > Apply
(FOR LION: If you can’t see an option to turn ipv6 off, set it to link-local only.)

Hey, There are afew things you can try.
- Simply turn your phone off and back on again
- Hold down your home button and your lock button and let goes as soon as the screen goes black (Phone will power down) - Then turn on your phone and hey presto!
- Back up your iPhone to your PC, then restore it..
this ones last cause I think you may have tried it already..
- Close all open applications
Hope this helps!

Hi guys.
I've had my MacBook Pro for 2 years now. Last night it suddenly kept glitching to a dark grey screen every now and then, then it would flash yellow / blue spots, and now it won't go past the grey screen even when I reboot it.
I don't think I can access my disk anymore as I've moved across countries since I've first gotten my laptop. it was working perfectly fine before it kept going to the dark grey screen with a little blue on the bottom.
If it helps, my camera light is still on, and it seems that my computer is working properly itself, but won't go past this grey screen.
I'm a college student and am really panicking about this - can anyone please tell me what to do?
Thank you & sorry for the long post.

What operating system are you running on it? (iOS 5.1 is for iPhone, iPad...not a Mac).

HT1212 my iphone 5's screen blacks out every now and then. the phone is turned on but the screen is black and i can receive calls. what is wrong with my phone

my iphone 5's screen blacks out every now and then. the phone is turned on but the screen is black and i can receive calls. what is wrong with my phone?

I have to believe this has something to do with iOS 7 issues. I have taken my screen blacked out 5s twice to the Genius Bar and the found a bunch of system apps had crashed. So if this is the case, is iOS7 the problem?

Synaptic touchpad stops working now and then on ProBook 6450b

The touchpad on my ProBook 6450b stops working every now and then. It just freezes, no error message or anything. It always works again after I reboot. It also starts working immediately if I go to the Task Manager and kill SynTPEnh.exe and then restart SynTPEnh.exe via Explorer (C:\Program Files\Synaptic\SynTP\SynTPEnh.exe). I have had this machine for 9 months, and these problems started only a couple of weeks ago. There are no error messages, and Device Manager says the device is working properly even when the touchpad is frozen. Sometimes I can go days without having a freeze, sometimes multiple freezes within minutes. Also, it happens during different activities - web browsing, watching movies, etc.
I'm not sure, but I might have enabled the WiFi-card in the BIOS prior to having these problems. However, as I currently need wireless, disabling it again is not an option.
I tried updating the BIOS, but the installation program wouldn't detect my SanDisk Cruzer USB stick, so I couldn't make a backup and decided to abort the procedure. I also tried installing another version of the Synaptic driver (can't remember the version, but it said "Evaluation Copy" on the Synaptic device in the Control Panel). It worked for a couple of days, then I got the old freeze again.
My setup:
HP ProBook 6450b
Windows 7 Professional 32-bit
Synaptic driver version 15.0.24

As a "quick'n'dirty" solution, I figured out how to automate this process. Simply create a new textfile called "Restart Synaptics.bat" and enter the following into it:
taskkill /IM SynTPEnh.exe /F
"C:\Program Files\Synaptics\SynTP\SynTPEnh.exe"
This will kill the SynTPEnh.exe process and then restart it. Now put a shortcut to your batch file in the Start Menu for easy access.
