CVS keyboard accelerators lost after restart
Hi
I set up accelerator keys for CVS edit (F10) and CVS commit (F11). Whilst JDeveloper is running, these keys work fine and I am able to edit and commit with these shortcut keys.
However, when I restart JDeveloper, the settings are lost and I have to set the keys again - (I have to do this each time I restart JDeveloper).
When I set keys F10 and F11 to other accelerator shortcuts such as make selected or run selected these work fine, even after restarting JDeveloper. The problem only seems to be with the CVS commands.
Do I have to some additional configuration for the CVS accelerators?
I am using JDeveloper 9.0.3.1 and the problem occurs on both Windows XP and SUSE Linux 8.1.
Thanks
UsmanI'm seeing this problem with set accelerators being lost after restart with JDeveloper Preview 10.1.3.0.2.
I set an accelerator to an external tool (Tomcat Startup and Tomcat Shutdown) and the accelerator is gone after I restart JDeveloper.
I apologize if this is a known bug in Preview... I did a cursory search through the forums and only found this one.
Thanks,

I have a new Panasonic TV with wireless capabilities. When I connect via my AirPort Extreme and access Netflix the connection is lost after about 5 minutes. I have moved the AirPort, shut down all other computers that use AirPort for wireless connection. How to rectify?

I have lost my iPhone on August 27, 2013 at 6:15 a.m. when I posizioned it on the strip for the scanner objet of Linate Airport.
After about 10 minutes when I was already on the plane my friend tried to call my number but the phone was already off.
By searching with the "Find my iPhone" system, the device is OFFLINE and does not appear on the map.
I have already written to the lost property office of the Linate Airport but at the moment they do noto have yet responded.
I have already forwarded the complaint to the police.
How can I find out it if my iPhone 5 is offline?
Thanks in advance for the answer.

Network connection is lost after a few hours
Hi Everyone.
I'm new to the Mac world.
I have two issues.
1. Is there a way I can always map my network drive on my mac to see my windows PC? I always have to manually connect to it.
2. I notice when I put the mac to sleep and I come back after a few hours I do not have connection to my network drive on my windows PC? It says that connection is lost or not available. It then takes another 3 minutes for it to recognize (beach ball thinking) and then I can proceed with my work.
Please help.
Thanks,
DraganI commented on that already in this thread in which someone did the same suggestion:
http://discussions.apple.com/thread.jspa?threadID=816760&tstart=15
I will copy and paste it:
switching to 802.11b isn't really the solution…
with 802.11b you're restricted to 11MBit/Sec and it switches quite fast to 5.5 MBit/Sec.
I have a card in my iMac that supports 802.11g (and even n - but for that I would need a new router…and the driver…an airport extreme base station is not really an option for me) and I want to use it. I want to be able to stream video in my home-network between the computers. With 802.11b it's not really possible. In addition I want a "fast" data transfer per WLAN - even though 11g isn't as fast as copper, it's definitly faster then 11b.
Apple should do something on that problem. Right now I'm on 11g only and that doesn't help… -

When i hold down command and r at the same time after restarting it comes up with a black screen and a lock symbol and a field bellow where you would input a password, i have tried ALL of my possible passwords including my password i use for the mac and it stil will not work! all that happens is the text i put in bellow erases itself after hiting enter or clicking the arrow.
I've tried my apple ID password and that doesn't work either . I don't recall seting a password for an encrypted disk either :/ if it was for an encrypted disk, would it be in keychain anywhere? if so how can i find it?

If you are not receiving calls and text messages reliably on your iPhone, I would start with the troubleshooting guide found at this page:

Just upgraded to latest iOS and my iPad does not come back up - the following appeared as the first thing after turning back on. It displays a line from the power/USB connector to an iTunes logo and then goes off and after some minutes comes back on. I cannot reset it or anything else. It is completely non-functional.

I tried downloading iTunes to my computer. It gives me an error where it says can not find iTunes Helper. I uninstalled all iTunes, restarted my computer, and then tried again. I keep getting the same error everyime. What can I do?
Apple Application Support was not found. Apple Application Support is required to run iTunes. Please uninstall iTunes, then install iTunes again. Error 2 (Windows error 2).
Many thanks. That issue will be causing the iTuneshelper error message too.
With the Error 2, let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR suitable for your PC (there's a 32-bit Windows version and a 64-bit Windows version). If the following link takes you to the WinRAR home page rather than the WinRAR downloads page, click the Downloads header in the box at the left of the WinRAR home page to see the trial version downloads:
http://www.rarlab.com/download.htm
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you? If so, see if iTunes will launch without the error now.
If instead you get an error message during the install, let us know what it says. (Precise text, please.) -

My early 2011 Macbook Pro on start up has wifi, but drops it soon after and never comes back, AHT shows nothing wrong. Multiple wifi's tried and same on all. I have also re-installed OSX from scratch and still happens.
I have the same problem. I have a white macbook 2010, with mavericks os. I just found my mac not powering on and then I tried to run it on safe mode by holding the shift button but it will turn off seconds after I let go of the shift button. I am able to access the desktop and use it while holding the shift button the whole time. It's a bit slower than before but I figured maybe it's because of holding down shift button.
I went to the Apple Store to have them look at my mac and I was told it's a failed hard disk. I wasn't told why he was able to conclude that a failed hard disk is causing the problem, I was just told to get a replacement. But the thing is when I ran Disk Utility it says, "disk appears to be okay." So I also feel like it's possible it's not a hard disk issue because it's also the first time it happened. My mac was working perfectly fine before all this.
Do you know anything else that could cause this problem? Were you able to find out what's wrong?
Thanks. -
Qosmio X500: Lan/Internet connection get lost after period of time
Hi all,.
I got the qosmio x500 for about half a year now...
I got this problem where after about 5 hours or less the lan/internet connection get lost.
I disabled the wireless connection and is using only the wired connnection now.
When it get disconnected... all devices seems to work seemlessly, no problem can be found. I checked the win7 network adaptor --and it seems to be connected properly.
I haven't got a slightest idea how to fix that.... Only a reset of the system and reloading the os results with a valid connection.
It is even stranger,. When using it for a piriod of time (listeding to audio streams from the web)... when getting back to the machine the audio connection seems to work properly.... but when trying to access other sites, or other machines in the homegroup, or network (under explorer). It result faulty.
Please guide me somehow how to fix the issue, it is bugging me a lot (all these resets to the machine probably doesn't do it any good as well).
thanks in advance,.Hi,
It could be the energy saving feature of your network card.
Right click Network Icon on the status bar, choose 'Open Network Center and Sharing', Click on 'Connection', Click on 'Properties' (low left button), you'll see the tab with your Network Properties. Click 'Configure' (Upper right button), choose 'Power Management' (last right tab).
Uncheck 'Allow computer to shut down this device to save energy'. Probably your problem will now be solved.
If the names I write aren't exactly right, I'm on a French language computer so my translations can be slightly wrong.
Bye,

Can't connect to database after restarting, TNS Error
I'm a little new to Oracle 10g administration. I successfully installed it on Oracle Enterprise Linux. Immediately after installation, I was able to connect to the default ORCL database using sqlplus. However, when I restarted the computer, I was no longer able to do so, even after restarting the listener service.
Here is the error I get:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
The other strange thing is, whenver I create a new database using dbca, immediately after that I can connect via sqlplus. However, if I perform a shutdown/startup, I get the same error as above. Restarting the listener doesn't make any difference.
A tnsping to my new database is successful but I can't connect to it from sqlplus.
Running the 'lsnrctl services' command immediately after making the new database shows it running but after a shutdown/restart only the default EXTPROC service shows.
Can anyone tell me why this happens and how to resolve it? Is there some other service I have to restart? Also, why does the listener not know of the service when it is explicitly configured in the tnsnames.ora file?
Note that I change my ORACLE_SID to the service name before attempting to connect.
Everything in the listener and tnsnames files was coded by the software, not by me.
Thanks for any help.
Here is my listener file:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /opt/oracle/product/10gR2)
(PROGRAM = extproc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = linux)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
______________________________________________I played around a little by deleting and creating databases. Here is my current tnsnames file:
TESTDATA =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = linux)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = TESTDATABASE)
ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = linux)(PORT = 1521))
(CONNECT_DATA =

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
I just made the database called TESTDATA. Here is the output of the command 'lsnrctl services', where the TESTDATABASE service refers to the database I just made:
