Accessing an IP address trouble shooting

I am trying access an IP address for my security camera system at my work. I am able to enter the IP address on any Windows based computer and have it work, but for some reason on my Mac it won't open the site. I use Safari as my browser. Does anyone know if I need to change any specific settings on my Mac or Safari? Any help would be greatly appreciated. BTW, I have tried this on my MacBook and on my big Mac at home and neither will open the site. Thanks

What actually happens when you try? Specifically, what error message do you get.
The error message will eliminate a lot of red herring answers.
For example, does Safari say it 'can't find server...' (which could be a DNS problem), or does it say 'cannot connect to the server' (which indicates a different class of network problem).
Or maybe you connect fine but you don't get a video image? That could be because the camera uses ActiveX for display rather than something that works cross-platform.
So, please re-post with more detail of what you're experiencing.

No IP address, everytime I'm close to my mums mac running off the same wifi, it's giving me this error. I can trouble shoot for about 3 mins and fix it, but it just keeps happening and I need a permanent fix for it. Any help?

this is what you need to do to exclude everything apart from desktop.
on time machine preferences, click on Options
click plus sign, on the new window, click macintosh HD
do a Control + A then deselect users then click okay
go to options again, plus sign, go to users, control +A then deselect your user account
go to options again, plus sign, go to your user account, control + A, deselect desktop
start the back up.

How do you access "trouble shoot" for mail. My AOL account is set up on the mail icon but it some how defaulted to another Wi fi account and could not receive email. We reset the the Wifi but somehow didn't complete the process.

How do you access "trouble shoot" for mail. Our AOL account is set up on the mail icon but somehow it defaulted onto another nearby Wifi account while everything else that was running stayed on our router. We were unable to receive email on the AOL account and were directed to trouble shoot. We reset the Wifi account but somehow didn't save it correctly. Now we cannot get back in to reset it again. Direction??

Hello
I don't really understand your question. The Mail application cannot independently access a different wifi network from the one your computer is using.
Are you trying to troubleshoot your wifi (ie, you can't get into your own wireless network), or the Mail program (you can't get email)? Are there any error messages you see when you try to do one or the other?

Have done all the trouble shooting connection but my iPad still can not get wifi connection

i have done all the trouble shooting connection but mu iPAd still can not get wifi connection

Hi Jo,
Each router is a little different but here are the basics: login to the router using the administrator account, should have that info from the installer, and then you should find something like security settings, or it may be advanced security. There will be a setting to the effect of limiting access, or it may say allow Mac address authentication, or admit the Mac addresses in the table...if that is switched on, you can just switch it off and that will allow any wireless device to attach. If you want to keep it on, then you have to enter the Mac address for the device you want to use for access. In the case of the iPad, go to Settings > General > About > WiFi Address (another way of saying Mac address). Enter that very long sequence in the router's Mac address acceptance table and that should take care of things.
Using the Mac address does not change any of the email settings, just limits attaching to the router in the first place.
If you are already getting email, you must be attaching already so this should not be an issue. If you are having email issues, such as receive but not send, you may not have the outgoing server set correctly: Settings > Mail > Account > Outgoing server name (usually an SMTP server) and you may have to go to the advanced settings to enter the outgoing password (normally the same as the account/incoming password) and then check to see if SSL is ON or OFF...most common email services say to set to OFF.

Trouble Shooting an iSight Camera. (Version 3)
Hi,     On many subjects Apple has Articles and Documents that can help.
In some case they are written by an Engineer or similar and can miss the mark for the average user.
In other cases they are crafted, detailed responses to an issue that has popped up many times in the Apple Discussions and take the best from many responses in those User-to-User Discussions, creating something that can not be surpassed.
This is the case of the Apple Article HT2090 on Trouble Shooting an iSight.
It lists steps and processes to go through for both Internal iSights and External ones.
However as with most things it does sometime pay to reword things differently so that people grasp the points in language they understand.
The info here is a reworking itself of two pages at ralphjohns.co.uk/EZ Jim pages namely EZ JIm's page 2 Where can I Find Help With My iSight ? and his page 4, How Can I Test My iSight is Completely Functional ? which were written several years ago and predate the Apple Article, being aimed at the External iSight. They have been updated since to address the Internal iSight as well but some of the comments are useful between the two types.
External First. For Internal iSights Start at 2b) (you will need to adjust some options/steps as the Internal is USB)
Steps
1) Pre Purchase
If buying an External iSight you should if you an get to see it in action.Apple no longer sells the External iSight so you will be buying it second hand.If you cannot get to see the device plugged in and working on Mac then check the smaller print of the seller and selling site as to nature of Returns and Faulty Goods.
2) Does it work ?
a) First of all Plug it in. It should come with a suitable mount (although there are variants on this) and a 6 pin to 6 pin Firewire cable.
Ideally it should have it's own Firewire port/socket on your computer. Connecting it "DaisyChained" to other devices can be a problem as they do not all use Firewire at the same Data speed.
It will then go through some checks as the OS powers it up and checks it's firmware.
Do not be concerned that the little green indicator light atop your iSight illuminates for a few seconds and then goes dark when you first connect your iSight or power on your Mac. Do not be concerned if you hear a soft whir as iSight attempt to focus either. Both these occurrences are normal. If your iSight passes the following tests, do not worry about this sound or the status of the green light.
There is no ON switch as such. It does have an iris mechanism that can be controlled by the User. The iris should be turned so you can see the Lens for the iSight to send pictures to an application.
b) Pick an Application to see the picture the iSight produces.iChat is one application you can use. Photobooth is another. iMovie (Version 4 or above for external iSight -- Version 6 or above for in-built iSight) and Comic Book (if bundled on your Mac) are yet more.
See this Users Tip for more applications Or this page for yet more.
Photo Booth is probably the simplest as it has no Preferences to choose a camera in the original version and is done from the Menu items in later versions (nor is there any setting in the OS) and Photo Booth will default to the External Camera if one is plugged in before the application is started.     If you see your self or what the camera is pointing at, It Works !!
3) If it does Not Work
a) Check Cables/leads. Re-seat the cable at both ends. DO this carefully as although Firewire cables are keyed to fit the right way it has been known to force them the wrong way.
Try another 6 pin to 6 pin firewire cable.
b) Unplug the cable from any other FireWire device and give the iSight it's Own FireWire port/socket on the Mac (exclude issues with other FireWire devices). It is important that this be a port/socket on your computer and that you know that it works. Do not use a port in a FireWire hub or another FireWire device or a FireWire port in an Apple Display for testing. (Also see d below if you have an 800 FIreWIre Computer)
c) Check System Profiler (Apple Icon menu top Left > About this Mac. > More Info Button)Open the Reveal Triangles to see the list and go to Hardware > FireWire. (Use USB for Internal Cameras)
If it appears here try booting or Logging in as another user on the Mac (Create a Test account if you don't have one) and try item 2b) above again.
d) With FireWire 800 computers you may have to change your FireWire 400 to 800 Adaptor or Cable to get full Audio functionality with Lion Apps
If it is not in the System Profiler you are almost certainly going to need the Trouble Shooting Article from Apple at this point. This Article may also be of help (number HT1317 What to do if your computer won't recognise a FireWire or USB device).
If you have not resolved things at this stage it is going to be time for an Engineer with Apple credentials.There are no user serviceable parts inside any iSight.
Other Items
Audio.
The External Camera has two mics inside.The volume it records at or plays through for iChat is controlled in System Preferences > Sound > Input tab (select device) and this should be set to get the blue response bar to at least half way (preferably three quarters) when you talk.The same applies to any other Mic, even the Internal one on laptops and some other Macs.
Firmware.
The System Profiler as detailed above should tell you the Firmware the iSight has. The current version is 1.0.3 and was updated in Panther. (Essentially it is an Audio compatibility update but does seem to help in other situations)
If your computer is running Panther (10.2.x) then use this Updater
If running Tiger (10.4.x) or Leopard (10.5.x) then navigate manually to your Hard Drive/System/Library/Core Services/iSight Updater and run the updater found there.
If an iSight is Plugged in on the Computer when you do an OS update and the firmware needs updating on the iSight this app is supposed to be triggered but it seem it may need a hand at times.
Focusing on the External iSight
Essentially the External iSight is self or Autofocusing.
If in doubt then try better lighting and strong colours as opposes to light or pastels.
(All built-in iSights are fixed focus. Therefore, unless a built-in iSight lens cover is dirty or smudged, any built-in iSight whose image is blurry needs service by an Engineer with Apple credentials.)
EZ Jim has these more specific recommendations for piece of mind.
Make a cross whose lines are about one-half inch or more wide on a plain background to use as a focus target. (I have even used black electrical tape.)
Turn on plenty of light and hold the target very still at about two or three feet from the lens. Watch iSight focus. (You may need to use a tripod or brace yourself to hold the target still enough.)
Then quickly move the target and hold it very still at about one foot away from the lens. Watch iSight focus.
Finally, move in to about six inches from iSight, and check focus there, too. (Holding the target still is more important as you get closer to iSight.)

TROUBLE SHOOTING PROBLEM ON SQL*NET, NET8.X, AND NET SERVICES
(GENERATING TRACE FILE OF SQL*NET, NET8.X, AND NET SERVICES)
==========================================================
PURPOSE
이 글은 고객들이 Oracle Server의 Oracle Networking 제품들을 사용하다가
Networking과 관련된 문제를 만났으나 스스로 해결할 수 없는 경우, 예를
들어 http://metalink.oracle.com 에서 같은 case를 발견할 수 없는 경우,
원인을 찾기 위하여 Networking 제품의 trace를 떠 보는 방법을 설명합니다.
Explanation
Oracle Networking 제품을 사용 중에 어떠한 문제를 겪는 경우 무엇보다도
OS의 Networking Protocol Stack 쪽을 살펴보는 것이 선행되어야 합니다.
일부 고객분들은 Oracle Networking 제품들이 OS의 Protocol Stack이 동작
하는데 어떤 중대한 영향을 주는 것이 아닌가 하고 문의를 합니다만
그러한 의문은 Oracle Networking 제품도 OS의 Protocol Stack을 사용하는
하나의 network client라는 것을 이해함으로써 해소가 됩니다.
Oracle Networking 제품도 OS의 Protocol Stack을 이용하는 하나의 network
client이기 때문에 Oracle Networking 제품이 OS Protocol Stack의 동작에
어떠한 식으로든 영향을 준다던가 하는 것은 있을 수 없기 때문입니다.
고객의 관점에서 OS의 Protocol Stack은 정상적으로 설정이 되었다고 믿고
있으며 기타 networking 환경을 정확히 판단할 수 없는, 예를 들어
host설정은 잘 되어 있다고 믿고 있으나 firewall을 통해야만 하는 등의
다소 접근하기 어려운 networking 환경에서 networking이 잘 되지 않는,
예를 들어, Oracle Server에 연결이 잘 안되거나 연결 중 networking
error가 발생하는 경우에는 http://metalink.oracle.com에서 같은 case를
찾는 것이 가장 빠른 해결 방법입니다.
그러나 드물게 http://metalink.oracle.com에서 같은 case가 나오지 않는
경우 Oracle Networking 제품의 trace file을 떠서 원인을 찾게 됩니다.
Oracle Networking 제품은 Oracle 7.x에서 SQL*Net, Oracle 8.x에서 Net 8.x,
Oracle 9.x에서 Oracle Net Services라는 이름이 가지고 있으나 여기에서는
편의상 모두 Oracle Networking 제품으로 부르도록 하겠습니다.
아울러 여기서 언급하는 Trace File은 Oracle Server의 Trace File과
다른 것입니다. Oracle Server의 Trace File은 database instance의 대한
내용만을 기록하며 Oracle Networking 제품의 Trace File은 networking에
대한 내용만을 기록합니다.
Trace File의 작성 방법은 Oracle 7.x부터 9.x까지 같습니다.
Solution Description
1. Client가 되는 host에서 어떠한 문제를 경험한 경우, 간혹 문제의 발생
빈도가 낮거나 network나 server 쪽에 이상을 느끼시면서도 문제를 확인하기
여러운 경우가 있습니다. 이런 경우엔는 문제가 다시 발생될 때 까지
Client에서 Client Trace File를 작성하여 보아야 합니다.
a. prompt$ echo $TNS_ADMIN
b. $TNS_ADMIN이 설정되어 있으면, prompt$ cd $TNS_ADMIN
아니면, prompt$ cd $ORACLE_HOME/network/admin
c. vi sqlnet.ora
# 다음 line들을 추가
TRACE_LEVEL_client=16
TRACE_FILE_client=<filename>
TRACE_DIRECTORY_client=<directory>
TRACE_UNIQUE_client=TRUE
:wq
prompt$
예를 들어, client가 Windows OS인 경우 다음과 같이 합니다.
prompt> notepad sqlnet.ora
TRACE_LEVEL_client=16
TRACE_FILE_client=client
TRACE_DIRECTORY_client=D:\temp
TRACE_UNIQUE_client=TRUE
prompt>
d. SQL*Plus와 같은, 또는 사용하던 Client software를 계속 이용
e. 다시 문제가 발생
f. 작성된 trace file들의 날자를 보아 문제가 발생한 시간과
거의 같은 시간에 작성된 file들이 있는지 확인
prompt> dir D:\temp
client_<PID1>.trc ...
client_<PID2>.trc ...
prompt>
g. trace를 중단합니다.
prompt$ vi sqlnet.ora
TRACE_LEVEL_client=0
:wq
prompt$
h. Trace Assistant를 이용하여 Oracle Networking 제품의 error code
(이하 TNS error code)를 trace file에서 찾아냅니다.
prompt$ cd <directory of TRACE_DIRECTORY_client>
prompt$ trcasst <filename of TRACE_FILE_client>_<PID>.trc > trcasst.out
prompt$ vi -R trcasst.out
Trace Assistant (trcasst command)는 Oracle 8.x부터 제공되며,
Oracle 9.x의 Trace Assistant를 사용할 것을 권합니다.
i. oerr command로 tns error에 대한 error message를 봅니다.
예를 들어, 흔한 경우 중에 listener가 실행 중이지 않거나 잘못된
tnsnames.ora 설정으로 client가 listener가 service 중이지 않은
network address로 연결을 시도하다가 TNS-12541 TNS-12560 TNS-511
error가 차례대로 나왔다면 다음과 같이 하여 각 TNS error code에
대한 message와 설명 및 해결방법을 볼 수 있습니다.
prompt$ oerr tns 12541
prompt$ oerr tns 12560
prompt$ oerr tns 511
j. Trace Assistant가 알려준 TNS error code를 http://metalink.oracle.com
에서 검색하여 같은 case가 있는지 확인합니다.
Web browser에서:
1) Go to http://metalink.oracle.com, then login
오른쪽 위 HTML frame에서 :
2) "Advanced" Button을 누릅니다.
오른쪽 아래 HTML frame에서:
3) "Enter Keyword" text box에 tns error code를 모두 입력합니다.
예를 들어, tns-12541 tns-12560 tns-511
4) "Search" button을 누릅니다.
k. http://metalink.oracle.com에서 검색이 거의 되지 않거나
문제가 매우 이상한 경우 이 글 아래를 보시기 바랍니다.
2. Client에서 SQL*Plus나 Oracle Client를 사용하는 다른 3rd party
appliction은 잘 동작하나 유독 tnsping command에서 error가 나는 경우가
드물게 있습니다. 이 때에는 tnsping command의 trace file을 작성해봅니다.
prompt$ vi sqlnet.ora
TNSPING_TRACE_LEVEL=16
TNSPING_TRACE_DIRECTORY=<directory>
:wq
prompt$ tnsping <tns alias>
3. Server, 즉 listener에 문제가 있다고 생각되는 경우 우선 listener의
log file을 봅니다. listener의 log에 대해서는 bulletin.18364를
이용합니다.
4. listener의 trace file은 다음과 같이 설정합니다.
listener의 trace 설정은 parameter 이름에 trace file을 작성하고자 하는
listener의 이름이 오는 점, 설정 후 listener process를 restart해야 하는
점 두 가지를 제외하면 나머지 절차가 앞서 설명드린 client와 같습니다.
prompt$ vi listener.ora
TRACE_LEVEL_<listener name>=16
TRACE_FILE_<listener name>=<filename>
TRACE_DIRECTORY_<listener name>=<directory>
:wq
prompt$ lsnrctl stop <listener name>
prompt$ lsnrctl start <listener name>
5. 만일 위와 같이 http://metalink.oracle.com을 검색하여도
같은 case가 전혀 없거나 찾아낸 error message들이 원인과 관련이 없어
보일정도로 매우 이상한 경우 다음과 같이 해봅니다.
a. Oracle Software의 version과 OS의 version이 certification matrix에
있는 지 확인합니다.
Web browser에서:
1) Go to http://metalink.oracle.com, then login
왼쪽 menu에서 :
2) "Certify & Availabilty" menu item을 click합니다.
오른쪽 아래 HTML frame에서:
3) 현재 사용중인 Product와 그 version 및 OS와 그 version을 선택하
여 검색합니다.
Certification Matrix는 매우 정확하게 정보를 보여주고 있습니다.
Matrix에 없는 Oracle Product와 OS version은 certify되어 있지 않으며
모든 Oracle 제품을 Certify되지 않은 OS version에서 사용하는 것은
그 어떠한 이유로든 보증과 지원이 되지 않습니다.
만일 사용중인 제품이 certify되지 않은 경우, 무조건 certify된 제품
과 OS의 version으로 install하여 다시 시도를 해야 합니다.
예를 들어, Windows OS의 경우 그 어떠한 Oracle 제품도 Windows Me 및
Windows XP Home Edition에 certify되어 있지 않습니다.
Windows 2000 Professional 이상에 Certify된 제품은 Oracle 8.1.6부터
이며 XP Professional 이상에 Certify된 제품은 Oracle 9.0.1부터
입니다.
Oracle 제품은 software이기는 하나 매우 완벽한 수준의 제품이라고 할
수 있습니다. 그러나 Oracle 제품은 하나의 OS의 process로써 실행이
되고 시간이 지나며 많은 환경이 major upgrade가 되면서 그러한 환경
에 따라 Oracle software도 새로운 version으로 제작이 되면서 다시
certification이 이루어지게 됩니다.
그렇기 때문에 고객들은 특히 다수의 client나 고가의 server를 계획하
시는 고객들은 저희 certification matrix를 사전에 철저히 확인하셔야
합니다.
앞서 Certification Matrix이전에 Installation Guide에 명시된
OS version만이 certify되어 있다고 생각하시면 되겠습니다.
b. Unix에서는 Oracle Software를 install한 후 OS의 Networking patch를
씌우고 사용하다보면 문제가 되는 경우가 있습니다.
이런 경우 relink를 해주어 바뀐 OS환경에서 Oracle 실행 file들을 다
시 만들어 주어야 합니다.
자세한 내용은 http://metalink.oracle.com에서
다음 글을 읽어 보시기 바랍니다.
Note:131321.1 How to Relink Oracle Database Software on UNIX
c. Certify된 환경에서도 원인을 찾을 수 없는 경우 trace file을 가지고
Oracle Support Services에 문의를 합니다. (지원 계약 고객에 한함)

Oracle Networking 제품도 OS의 Protocol Stack을 이용하는 하나의 network
client이기 때문에 Oracle Networking 제품이 OS Protocol Stack의 동작에
어떠한 식으로든 영향을 준다던가 하는 것은 있을 수 없기 때문입니다.
고객의 관점에서 OS의 Protocol Stack은 정상적으로 설정이 되었다고 믿고
있으며 기타 networking 환경을 정확히 판단할 수 없는, 예를 들어
host설정은 잘 되어 있다고 믿고 있으나 firewall을 통해야만 하는 등의
다소 접근하기 어려운 networking 환경에서 networking이 잘 되지 않는,
예를 들어, Oracle Server에 연결이 잘 안되거나 연결 중 networking
error가 발생하는 경우에는 http://metalink.oracle.com에서 같은 case를
찾는 것이 가장 빠른 해결 방법입니다.
그러나 드물게 http://metalink.oracle.com에서 같은 case가 나오지 않는
경우 Oracle Networking 제품의 trace file을 떠서 원인을 찾게 됩니다.
Oracle Networking 제품은 Oracle 7.x에서 SQL*Net, Oracle 8.x에서 Net 8.x,
Oracle 9.x에서 Oracle Net Services라는 이름이 가지고 있으나 여기에서는
편의상 모두 Oracle Networking 제품으로 부르도록 하겠습니다.
아울러 여기서 언급하는 Trace File은 Oracle Server의 Trace File과
다른 것입니다. Oracle Server의 Trace File은 database instance의 대한
내용만을 기록하며 Oracle Networking 제품의 Trace File은 networking에
대한 내용만을 기록합니다.
Trace File의 작성 방법은 Oracle 7.x부터 9.x까지 같습니다.
Solution Description
1. Client가 되는 host에서 어떠한 문제를 경험한 경우, 간혹 문제의 발생
빈도가 낮거나 network나 server 쪽에 이상을 느끼시면서도 문제를 확인하기
여러운 경우가 있습니다. 이런 경우엔는 문제가 다시 발생될 때 까지
Client에서 Client Trace File를 작성하여 보아야 합니다.
a. prompt$ echo $TNS_ADMIN
b. $TNS_ADMIN이 설정되어 있으면, prompt$ cd $TNS_ADMIN
아니면, prompt$ cd $ORACLE_HOME/network/admin
c. vi sqlnet.ora
# 다음 line들을 추가
TRACE_LEVEL_client=16
TRACE_FILE_client=<filename>
TRACE_DIRECTORY_client=<directory>
TRACE_UNIQUE_client=TRUE
:wq
prompt$
예를 들어, client가 Windows OS인 경우 다음과 같이 합니다.
prompt> notepad sqlnet.ora
TRACE_LEVEL_client=16
TRACE_FILE_client=client
TRACE_DIRECTORY_client=D:\temp
TRACE_UNIQUE_client=TRUE
prompt>
d. SQL*Plus와 같은, 또는 사용하던 Client software를 계속 이용
e. 다시 문제가 발생
f. 작성된 trace file들의 날자를 보아 문제가 발생한 시간과
거의 같은 시간에 작성된 file들이 있는지 확인
prompt> dir D:\temp
client_<PID1>.trc ...
client_<PID2>.trc ...
prompt>
g. trace를 중단합니다.
prompt$ vi sqlnet.ora
TRACE_LEVEL_client=0
:wq
prompt$
h. Trace Assistant를 이용하여 Oracle Networking 제품의 error code
(이하 TNS error code)를 trace file에서 찾아냅니다.
prompt$ cd <directory of TRACE_DIRECTORY_client>
prompt$ trcasst <filename of TRACE_FILE_client>_<PID>.trc > trcasst.out
prompt$ vi -R trcasst.out
Trace Assistant (trcasst command)는 Oracle 8.x부터 제공되며,
Oracle 9.x의 Trace Assistant를 사용할 것을 권합니다.
i. oerr command로 tns error에 대한 error message를 봅니다.
예를 들어, 흔한 경우 중에 listener가 실행 중이지 않거나 잘못된
tnsnames.ora 설정으로 client가 listener가 service 중이지 않은
network address로 연결을 시도하다가 TNS-12541 TNS-12560 TNS-511
error가 차례대로 나왔다면 다음과 같이 하여 각 TNS error code에
대한 message와 설명 및 해결방법을 볼 수 있습니다.
prompt$ oerr tns 12541
prompt$ oerr tns 12560
prompt$ oerr tns 511
j. Trace Assistant가 알려준 TNS error code를 http://metalink.oracle.com
에서 검색하여 같은 case가 있는지 확인합니다.
Web browser에서:
1) Go to http://metalink.oracle.com, then login
오른쪽 위 HTML frame에서 :
2) "Advanced" Button을 누릅니다.
오른쪽 아래 HTML frame에서:
3) "Enter Keyword" text box에 tns error code를 모두 입력합니다.
예를 들어, tns-12541 tns-12560 tns-511
4) "Search" button을 누릅니다.
k. http://metalink.oracle.com에서 검색이 거의 되지 않거나
문제가 매우 이상한 경우 이 글 아래를 보시기 바랍니다.
2. Client에서 SQL*Plus나 Oracle Client를 사용하는 다른 3rd party
appliction은 잘 동작하나 유독 tnsping command에서 error가 나는 경우가
드물게 있습니다. 이 때에는 tnsping command의 trace file을 작성해봅니다.
prompt$ vi sqlnet.ora
TNSPING_TRACE_LEVEL=16
TNSPING_TRACE_DIRECTORY=<directory>
:wq
prompt$ tnsping <tns alias>
3. Server, 즉 listener에 문제가 있다고 생각되는 경우 우선 listener의
log file을 봅니다. listener의 log에 대해서는 bulletin.18364를
이용합니다.
4. listener의 trace file은 다음과 같이 설정합니다.
listener의 trace 설정은 parameter 이름에 trace file을 작성하고자 하는
listener의 이름이 오는 점, 설정 후 listener process를 restart해야 하는
점 두 가지를 제외하면 나머지 절차가 앞서 설명드린 client와 같습니다.
prompt$ vi listener.ora
TRACE_LEVEL_<listener name>=16
TRACE_FILE_<listener name>=<filename>
TRACE_DIRECTORY_<listener name>=<directory>
:wq
prompt$ lsnrctl stop <listener name>
prompt$ lsnrctl start <listener name>
5. 만일 위와 같이 http://metalink.oracle.com을 검색하여도
같은 case가 전혀 없거나 찾아낸 error message들이 원인과 관련이 없어
보일정도로 매우 이상한 경우 다음과 같이 해봅니다.
a. Oracle Software의 version과 OS의 version이 certification matrix에
있는 지 확인합니다.
Web browser에서:
1) Go to http://metalink.oracle.com, then login
왼쪽 menu에서 :
2) "Certify & Availabilty" menu item을 click합니다.
오른쪽 아래 HTML frame에서:
3) 현재 사용중인 Product와 그 version 및 OS와 그 version을 선택하
여 검색합니다.
Certification Matrix는 매우 정확하게 정보를 보여주고 있습니다.
Matrix에 없는 Oracle Product와 OS version은 certify되어 있지 않으며
모든 Oracle 제품을 Certify되지 않은 OS version에서 사용하는 것은
그 어떠한 이유로든 보증과 지원이 되지 않습니다.
만일 사용중인 제품이 certify되지 않은 경우, 무조건 certify된 제품
과 OS의 version으로 install하여 다시 시도를 해야 합니다.
예를 들어, Windows OS의 경우 그 어떠한 Oracle 제품도 Windows Me 및
Windows XP Home Edition에 certify되어 있지 않습니다.
Windows 2000 Professional 이상에 Certify된 제품은 Oracle 8.1.6부터
이며 XP Professional 이상에 Certify된 제품은 Oracle 9.0.1부터
입니다.
Oracle 제품은 software이기는 하나 매우 완벽한 수준의 제품이라고 할
수 있습니다. 그러나 Oracle 제품은 하나의 OS의 process로써 실행이
되고 시간이 지나며 많은 환경이 major upgrade가 되면서 그러한 환경
에 따라 Oracle software도 새로운 version으로 제작이 되면서 다시
certification이 이루어지게 됩니다.
그렇기 때문에 고객들은 특히 다수의 client나 고가의 server를 계획하
시는 고객들은 저희 certification matrix를 사전에 철저히 확인하셔야
합니다.
앞서 Certification Matrix이전에 Installation Guide에 명시된
OS version만이 certify되어 있다고 생각하시면 되겠습니다.
b. Unix에서는 Oracle Software를 install한 후 OS의 Networking patch를
씌우고 사용하다보면 문제가 되는 경우가 있습니다.
이런 경우 relink를 해주어 바뀐 OS환경에서 Oracle 실행 file들을 다
시 만들어 주어야 합니다.
자세한 내용은 http://metalink.oracle.com에서
다음 글을 읽어 보시기 바랍니다.
Note:131321.1 How to Relink Oracle Database Software on UNIX
c. Certify된 환경에서도 원인을 찾을 수 없는 경우 trace file을 가지고
Oracle Support Services에 문의를 합니다. (지원 계약 고객에 한함)

Trouble shooting apex application calling web-service reference

Hi,
I am developing an APEX application which calls a web-service reference. i am looking for ideas as to how to log necessary information for trouble shooting.
i already thought about this -
1. the response from the web-service is displayed to the user (via a collection object).
but the issue is i want the administrator (who logs in at a later time) to see that an error occurred or what was the response from the web-service.
Is there any in-built way of accessing this information (is it first of all stored somewhere automatically ?). the one possible solution i see is to create a table and log the info into this table along with user and session id.
any ideas / pointers will greatly help me.
Regards,
Ramakrishnan

It looks like you won't be able to test web service calls on apex.oracle.com. see this WebService on apex.oracle.com

MacOS X 10.4: Basic trouble-shooting

Here is a check-list for some basic, unspecific trouble-shooting.
1. Restart the computer
2. Deactivate/Uninstall system haxies and third-party extensions (e.g. ASM, Norton AntiVirus, etc.)
3. Check/fix the filesystem as outlined in this article: Using Disk Utility and fsck for file system maintenance in Mac OS X and Using Disk Utility in Mac OS X 10.4.3 or later to verify or repair disks
4. Check for at least 5 GB of free space on the boot volume. Mac OS X needs at least that amount in order to run properly.
5. Repair permissions: Go to Applications > Utilities > Disk Utility, choose your HD in the sidebar and click "Repair Permissions"
6. If one specific application gives you a headache, trash it's preference-file (User/Library/Preferences or in case of system "programs"
in Library/Preferences).
7. Create a new user account, and see if the problem persists.
8. Clear system & user caches with either Tiger Cache Cleaner or Cocktail.
9. Unplug all USB- and Firewire devices except original Apple mouse and keyboard.
10. Startup in Safe-mode and see if the problem persists: Starting up in Safe Mode
11. Repair and replace the directory with DiskWarrior or TechTool Pro 4
12. Zap PRAM: How to Reset PRAM and NVRAM
13. Unplug 3rd Party PCI cards.
14. Reinstall the latest combo updater.
15. Check the hard drive for bad blocks (e.g. with Drive 10 or TechTool Pro 4).
16. Take out 3rd party RAM.
17. Run the Apple hardware diagnostic CD.
18. Reset PMU: Resetting Power Management Unit (PMU), Power Mac G4 (AGP Graphics/Gigabit Ethernet): Resetting the PMU on the Logic Board, Resetting PowerBook and iBook Power Management Unit (PMU)
19. Reinstall the system from scratch ( http://discussions.apple.com/thread.jspa?messageID=607614

4. Check for at least 5 GB of free space on the boot volume. Mac OS X needs at least that amount in order to run properly.
Mac OS X 10.4 will work properly with less free space; about 2 or 3GB is enough. I currently have 4.03GB free on my Mac OS X 10.4 system, which is on a 7.3GB partition.
6. If one specific application gives you a headache, trash it's preference-file (User/Library/Preferences or in case of system "programs" in Library/Preferences)
The first path should reference the folder in the Finder's sidebar or choosing Go to Folder from the Finder's Go menu and entering ~/Library/Preferences as the location. A home folder does not need to be in /Users/, and in any case, the file should be left on the desktop temporarily instead of being immediately deleted.
You may also want to mention display issues which are account-specific; these include colors looking washed out, the monitor's colors being inverted, and a black box appearing on random items. These can be turned off from the Universal Access pane of System Preferences.

Apple Trouble Shooting Guide TS3304

Apple has posted a new Trouble Shooting Guide addressing the WiFi problems that some iPad users have been having. See http://support.apple.com/kb/TS3304?viewlocale=en_US
There are work arounds in the TS, some of which have been suggested in these forums. There is promise of a S/W update to address these problems.

When connecting to a "hotspot" be it public or inside a business, you have only 2 options provided by this TS. Either renew IP or turn off "auto" screen brightness. Flimsy at best.
I predict with the next software update those like me who have yet to connect to wifi at a hotel, coffee shop or fast food joint will continue to be wifi-less. Meaning I think it's a hardware problem. The good news is you can spin the referb roulette wheel by trading in your factory fresh model for one that's been assembled, disassembled and reassembled.
Hope I'm wrong because I would like to use this device away from home and I don't want a referb. Went through several of those dogs with the iPhone. My advice, wait until the update or at least 3 months to get the dogs out of the system. Jaded.

Airport Extreme trouble shooter pop up

I just started having the AIrport Extreme trouble shooter pop up on my mac book pro when started or restarted with this message.
"This Apple WiFI base station does not have any DNS server addresses and might have problems connecting to the network."
I installed Lion and icloud several weeks ago but the error message has just started popping up.

DNS is the equivalent of the Yellow Pages for the Internet. Normally your computer would be provided with the IP addresses of the DNS servers used by your ISP automatically since most computers, by default, are configured as DHCP clients. DHCP is what "pushes" these IP addresses to your device.
Also, by default, your AirPort Extreme router has a built-in DHCP server which would get these DNS IP addresses from the ISP and supply them to any wired or wireless client that connects to the Extreme's network.
You can determine which DNS IP addresses that your Mac got by looking at System Preferences > Network > AirPort > Advanced > DNS tab
You should find the DNS server IP address(es) provided by your ISP.

I had a 1 TB Drive that was connected as a back up, but it is no longer recognized by the mac. How may I trouble shoot to reconnect?

how do I trouble shoot this?

Good News.
If this is your only Backup would suggest getting a New EHD and creating another one... Preferably a Clone if you don't already have one.

Can never have too many Backups...

I uploded the new itunes software and now my ipod touch is not getting reconized in my itunes. I went through all the trouble shooting support from apple. But I do have a avast antivirus on my computer i wonder if that is what is holding it up

Could be since it (security software) is listed as #5 in the following:
iPhone, iPad, or iPod touch: Device not recognized in iTunes for Windows

TS4268 Ever since I uploaded i0s7 I haven't been able to receive I messages or face time. I have took it to the apple store and they couldn't figure it out. I have also followed the trouble shooting from I tunes and still can't get it working

Hi,
Strikes -
Go into compositionReady and have 3 variables you will be able to set them like this
strike1 = 0;
strike2 = 0;
strike3 = 0;
So on the wrong item click have
if(strike1 == 0) {
PLAY STRIKE1 ANIMATION
strike1 = 1;
else if(strike2 == 0) {
PLAY STRIKE2 ANIMATION
strike2 = 1;
else if(strike3 == 0) {
PLAY STRIKE2 ANIMATION
strike3 = 1;
So this will make it so when the wrong item is clicked each strike will be played in order.
Random Scrolling -
You should look into the Math.Random function to make things random in edge.
This is an example of the Random function. It will generate a random number up to 100.
var random = Math.floor (Math.random () * 100);
Lose Screen Score -
So we can create another variable in compositionReady for the lose score.
score = 0;
Now when the user gains a point to add to the score you could do this code on the click
score++;
which would add 1 to the score, However you can add however much you like to the score doing "score + 2" and so on.
To edit a text with the score at the end which I'm assuming you will want to do you will use .html
so $("Text").html("You score is " + score);
I hope this helps!
