Problems when I try to connect to sqlplus
Hi,
Can someone help me with the following problem?
When I try to connect to sqlplus I get this response
"ora 12514: listener could not resolve SERVICE_NAME given in connect descriptor "

There are lots of mismatches in your files.
Tnsnames point to a host called "orcl" but listener is listening on user.mycomputer.com. Why it is so ?
Second, in the listener.ora , the global db name is set to Oracle8 while sid is set to ORCl.
Can you try removing all these , match the files, restart teh listener and retry connection please?

I´ve a problem when i try to connect to a wifi signal, an external browser is launched and it goes blank. Someone knows apple-urls that are called in this case?, i was thinking to add to a whitelist into my router.
Thanks.Contact your it department.
You are blocked by a firewall. -
It seems that all apple products used in my house at times will not connect to our wifi. It's hit and miss. It says I am connected, but when you try to connect to any search engine it does not. I have disconnected and reconnected the power to the dsl provider and to our wifi units. I have rebooted the computers. I have reentered the password. Still no connection. We do not have connectivity issues with our PC products. Anyone have any answers for me?
Does the iOS device connect to other networks?
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:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

I just bought an Apple TV and am trying to set it up. I am connected to wireless, is having difficulties setting time and date. When I try to connect to iTunes and sharing. It keeps telling me that there is a problem with my apple ID and password. I have quadruple checked and re-entered and it won't recognise it. What do I do? Dan.
Sounds like it is more an issue of connecting to the internet. Not just the WiFi Some people have reported that performing a power cycle on their Internet router solved this.

i have a problem when i try to update or install apps in my ipad, and a message come up says "can not connect to Itunes Store", anyone know why? please advise. however i had update all my detail of payment method.
Settings > General > Reset > Reset Network Settings.
Power cycle the router.
Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved. -

I will provide u with the code.

public class DataBaseVector extends JPanel
//Container contentPane=getContentPane();
JScrollBar jsb = new JScrollBar(JScrollBar.HORIZONTAL);
JScrollBar jsb1 = new JScrollBar(JScrollBar.VERTICAL);
Image i1;
String url="jdbc:odbc:Ananth";
Vector col=new Vector();
Vector rows=new Vector();
Vector rdata=new Vector();
Connection conn;

JFrame jf=new JFrame();
JPanel frame=new DataBaseVector();
jf.getContentPane().add(frame);

Thanx,
m.ananthuThe problem is ResultSet.next() is not called.
Try this and modify the table creation as you need.
ResultSetMetaData rsmd=rs.getMetaData();
int cols=rsmd.getColumnCount();
while(rs.next()) {
for(int i=1;i<=cols;i++)
col.addElement(rsmd.getColumnName(i));
rdata.addElement(rs.getString(i));
rows.addElement(rdata);
Hope this helps -

I have an iphone 4s and when I try to connect to my shared library I see an icon of a circle that only becomes half full. It does not connect. I also have an ipad, which connects without incident. My itunes library is larger than the capacity of both devices, so that cannot be the issue. How can I get the phone to connect with my shared library?
My husband and I are using the same iTunes account on all mac & pc computers, but the libraries are different on each machine. We always manually manage our music (no auto sync). iTunes is up to date on the PCs. My husband uses our joint iTunes account on his pc, but once again, has a different collection in his library from those on the other machines. He can't load any music from his PC to his iphone 4. I can load music from my mac library to my iphone 4s, but cannot load from my pc library to my iphone 4s. How can I switch my main library that it syncs with from the mac to the pc?
Thanks -

Hi Fellows.
I'm trying to Connect Discoverer Desktop 9.0.4.43.17 to Oracle Database 11.2.0.1. I Installed the program (Windows 7 Emulating XP SP3) But when I try to connect to Database send me ORA-02248 Error, some Alter Session. I'm Using a user with DBA privileges But I cannot Connect to Database, Do I have to Install an Additional Software or create a Special User or Schema????

Thanks for your time.

A few months back I Dropped my iPhone 4 and I cracked my screen and now i cant unlock my phone due to touch screen not working plus there are blurred lines across the screen and I can't see anything that it displays.
Now when I try too connect my iPhone 4 to iTunes on my computer at home an error message comes up saying that I have to unlock my iPhone 4 for it to communicate to my device.
But the problem is that I can't unlock my iPhone 4 because I'm unable to see the key pad and my touch screen no longer responds when I touch it.
I just want to reset my iPhone 4 back to its Factory Settings & start all over from the beginning.
How can I unlock my iPhone 4 with iTunes on my computer or any other option you suggest me trying.
Thank you in advance,
SiHeroIf you have had a "local guy "repair your iphone you will not get any support from Apple for warranty OR post warranty
If Verizon return it to Apple it wil not be handled by Apple
If Verizon also use unauthorised repairers you may be lucky
(Apple do not sell parts to local guys or anyone else )
