Re: sqldeveloper and jdeveloper cannot connect to xe service

Hi RusseIIM,
Even i am facing the same issue.
when my office PC is connected to n/w, nothing workson OracleXE.
If not everything works fine.
My PC is secured with Mcaffee.
can any one help?
Thanks & regards,
Vamshi P.

Take a look (in a cmd box) at your `ipconfig /all` output. If there truly is no network interfaces configured, starting up a listener won't work very well with the out-of-the-box setup.
Doesn't matter how its configured, when there is no network, there is no way to (reliably) start a listener. Depending on how the host networking was configured at install time, the %ORACLE_HOME%\network\admin\listener.ora file may require some adjustment(s).
A possible workaround might be setting the ...HOST= to the 0.0.0.0 "any IP" address. That might get the listener to service the loopback interface when all other network interfaces are unavailable. Its localhost a.k.a. 127.0.0.1, and the *only* place one can hit the 127.0.0.1 address is when one tries from that particular host. Loopback is mainly used to check if TCP/IP is installed/configured.

Sqldeveloper and jdeveloper cannot connect to xe service

I just installed xe on my pc. I can get into sqlplus create users, tables data etc. Everything seems to work. I can also run lsnrctl and everything seems to be ok. I can also do a tnsping and get a positive response. sqldeveloper and jdeveloper both get errors when I try and connect.
I used to get an error indicating that the listener did not know about the XE service or sid (tried it both ways). I changed the node names that were in the listener.ora file to localhost and the error changed to a 17002. I am now getting the original 12514. listener does not know the service in the connect descriptor. How do I fix this? It has not worked since I installed it.
Thanks,
Russell

I have tried using sqldeveloper and defining a connection. I have also tried defining a connection in jdeveloper and that fails in the same way. I have also tried using sqlplus user/pass@XE and that fails the same way. The tnsnames.ora, listener.ora are all in the default location. ...server\network\ADMIN.
lsnrctl returns the following:

It asks for a proxy. I have put the google proxy 8.8.8.8 and 8.8.4.4 but these don't work. What proxy & port can I use?
thanks for your help.

Hi Nancy,
I'm sorry to hear that you are having problems with your print apps not printing as scheduled.
To better assist you, would you please provide some further information:
Has there been any changes to your home network (new internet provider, new router, or new network password)?
Are you able to send to print jobs to the printer's ePrint email address?
Thank you.

If not this:
iOS: Wi-Fi or Bluetooth settings grayed out or dim
One user reported that placing the iPod in the freezer fixed the problem.
Also heating sometimes works. See:
Why can't I select my wifi settings?
A trick that works frequently with iPhones:
Settings > AirPlane Mode ON, Do Not Disturb ON
Power down and wait 5-10 minutes
Power up
Settings > AirPlane Mode OFF, Do Not Disturb OFF

Then:
Does the iOS device connect to other networks? See other networks? If yes that tends to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:

- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

We have just installed Lion and now cannot connect to MyExpat

we have just installed OS X Lion, v10.7.2 and now cannot connect to MyExpatNetwork on my Macbook pro. Any suggestions?

yeah-find out where you're downloading stuff to, and stick with it. I'm using FireFox and tell it to save the driver and stuff on the desktop, and when I quit FireFox, there it is on the desktop. you'll also need your admin password. It should show up as a .dmg file, then double-click on it to open it. You should see "Brother.pkg" . start up brother.pkg (double click??) and folow the instructions that ought to appear to install the printer driver. If the .dmg file doesn't mount, use Disk Utility** to mount it and get it working. Then you should see the package. and then you can install it.
** you may have to click on the .dmg file and choose "Get Info" then Open with, then choose disk utility, and then open with then change all. then close it. Hopefully that ought to work. If you cannot remember your admin password, I can't help you right now. Looks like you'd need it, to let Brother install that printer driver.
well, enough for tonight
if this didn't help you, then ask me again tomorrow

HT4628 My Mac Air OSX10.8.5 won't connect to the internet as it says it has a self assigned IP address and thus cannot connect to the internet. I can only connect to a network by manually typing in the configuration specs. Please help.

My mac air OSX10.8.5 won't connect to the internet. It says it has a 'self assigned IP address and therefore cannot connect to the internet'. Network diagnostics is unable to the solve the problem. It happened suddenly for no reason and now I cannot connect except by typing in the configuration settings manually. Please help me!

Use the Airport Utility or log into your wireless device via http and ensure the DHCP/NAT service is enabled. If accessing via HTTP, you will need to manually set an ip within your local subnet (eg: 192.168.0.x).

PowerPoint - Present Online - Error starting online presentation - Cannot connect to this service. Check your network connection and try again.

"Present Online
Error starting online presentation
Cannot connect to this service. Check your network connection and try again."
On March 31, we starting experiencing this issue across our entire domain. We have not made any changes to our network configuration. We are using the same ISP, routing hardware, computer hardware, software versions and group policy settings as we were on March
30.
The issue appears to be related to network connectivity.
Here is what I have found so far:
We have three networks in our building and two ISPs.
Network-A uses ISP-A and is affected by the issue. Network-A is our corporate domain.
Network-B uses ISP-B and is affected by the issue.
Network-C uses ISP-B and is not affected by the issue.
If I take a Network-A domain member and launch PowerPoint while connected to Network-A and ISP-A I am unable to upload PowerPoint presentations.
If I connect the same computer to Network-C, the issue persists.
If I close PowerPoint, connect to Network-C, and reopen PowerPoint while connected to Network-C, I am able to upload presentations.
A non-domain computer is affected by the issue if PowerPoint is opened while connected to Network-A or Network-B, but unaffected if PowerPoint is launched while connected to Network-C. Again, in this scenario, switching connections while PowerPoint is open
has no effect.
The issue appears to be caused during PowerPoint start-up and not while attempting to share a document.
Microsoft is either unwilling or unable to find a resolution and has finally resorted to simply ignoring my calls, voicemails, emails, and ticket requests regarding this issue. Any suggestions would be greatly appreciated.

If no computer:
Only if:
If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone and use Remote Wipe to erase the contents of your device. If you have been using iCloud to back up, you may be able to restore the most recent backup to reset the passcode after the device has been erased.
You can also wipe the iOS device by installing the FindMyiPhone app on another iOS device and using that app to wipe the device.
Otherwise you need a computer with iTunes and an internet connection
Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Forgot passcode or device disabled
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.

- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
