Any password acceptable
Hi,
I am a beginner in oracle development, I have installed Oracle 11gR2. then, I created 2 databases.
the problems i face are that
1)
using command Prompt -> sqlplus
and login with username: sys as sysdba
however it accepts any password!!!!! why does it accept any password?
How do I know which database has it connected to?
2)when I want to create a connection in SQL Developer, It giving error saying that the network adapter could not establish connection.

for the "any password" issue, that's because you are making a local connection, using an OS account that is a member of the os DBA group. It's called OS Authentication, if you want to read up on it in the Oracle docs. Which you should
As for how to know which database you are connected to , or how to select which database you connect to .. if you are doing a local connection, you make the selection by setting the enviornment variable ORACLE_SID to specify which database you want to connect to. If connecting to a remote database, you specify a 'net service name', like this:
sqlplus scott/tiger@mydb

my ipad wont accept any passwords, i am unable to connect to my wifi even though my password is correct and other laptops etc have no problem connecting.
The ipad can find my wifi connection but just wont accept the password. connected with no problem in the Apple store.
any suggestions,
thanks.Does the iPad connect to other networks?
Does the iPod see the network?
Any error messages?
Do other devices now connect?
Did the iPod 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 the 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.

Can't accept any password dialogs in KDE [PARTIALLY SOLVED]
Hi,
Since my last upgrade (yesterday, hadn't updated for a week), im having problems to enter any password inside KDE's password dialogs (kdesu, kwallet, kontact, kopete....)
The passwords just type in fine, but the "accept" button, or pressing enter wont do anything. The password dialog just stays there.
Using Arch x86_64.
Thanks.

On my Iphone 4s, I can not get any response accept the apple logo after recharging for an entire day and trying to connect to iTunes. A few days before that the speaker suddenly stopped working during a call. I also reset everything by connecting to itunes but no luck then. help?
Hey there xntricj,
It sounds like you are putting a password for your Apple ID that works without issue on your iPad into your iPhone but get a message saying that the password is incorrect. I recommend the steps from the article named:
iCloud: "Incorrect Apple ID or Password" alert when setting up iCloud after upgrading to iOS 7
http://support.apple.com/kb/TS5207
After completing iOS 7 setup, go to Settings > iCloud.
Scroll down and tap Delete Account, then enter your previous Apple ID and password.
If your Apple ID or password are not accepted, follow the steps in iOS 7: If you're asked for your previous Apple ID when signing out of iCloud.
Thank you for using Apple Support Communities.
All the very best,

I bought a new macbook air pre loaded with Lion. while setting up the system, I just input the user name, and didn't set any password.
But now when I wanna download stuff off safari, it asks me for password. The user name appears (the same one which I set) but it keeps on asking me the password which I never set. Can some one please help me. Thanks!I did it like that, but for the purpose of not having to type my password every time since I'm installing a lot of programs, and yes, it asks for the password, but do not type anything and just click "ok" or "install", since you haven't set a password it should let you go through. I guess it asks for the "password" just to let you know it will install something, but just click ok.
I will set up a password once i have install everything in System Preferences/Users & Groups
Hope it helps... -
Hi , i just restored my iPhone and now that i wanna restore my backup (contacts) it's locked i didnt put any password when i was backing up , any idea ?
Encrypting an iPhone backup doesn't happen accidentally. Either yourself or someone had to specifically select that option...by someone, that could be a work Exchange account...a profile installed on your phone when setting up the Exchange account can force the encryption of iPhone backups.

I tried to launch iCloud on iMac. I Changed my e-mail address recently, and iMac doesn't seem to know it. Even worse, it doesn't know any password I've used with Apple ID. Can anyone help me?
No, i don't. if i did i would have tried it. do you have to sign up an appled ID for iCloud? If the answer is yes then they should mention that in the set-up instructions.

My bookmarks toolbar in Firefox 10.0.2 Mac OSX 10.6.8 suddenly disappeared. View>Toolbars>Bookmarks Toolbar is checked. Dragging URL's to the bookmarks toolbar area no longer works. The gray area appears and disappears when checking/unchecking under View/Toolbars menu, but will not show any or accept addition of bookmarks.
Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible: "View > Toolbars"
*Open the Customize window via "View > Toolbars > Customize"
*Check that the "Bookmarks Toolbar items" is on the Bookmarks Toolbar
*If the "Bookmarks Toolbar items" is not on the Bookmarks Toolbar then drag it back from the toolbar palette in the customize window to the Bookmarks Toolbar
*If missing items are in the toolbar palette then drag them back from the Customize window on the toolbar
*If you do not see an item on a toolbar and in the toolbar palette then click the "Restore Default Set" button to restore the default toolbar set up

hey guys i forgot the password for my iphone 4S and i keep on trying any passwords but now my iphone has deactivated it self and its asking me the password but i cant remember it and i dont have the last compter it syniced with!!! so what should i do ?
In your case your only solution is to restore it ( see http://support.apple.com/kb/HT1808 ) and you may need to force it into restore mode to do that. This will wipe everything off it and reset it as new, without the passcode. You can then redownload purchased content, buy unless you have a sync'd copy of your contacts and photo's they will be gone.

Firefox is suddenly not remembering or filling in any of my passwords. All of the appropriate boxes are checked in the options/security tab, but it won't remember any passwords and shows none saved. How do I get it to remember and fill in my passwords again?
Do you mean names and passwords in the Password Manager or do you mean that you are no longer logged on to (remembered by) websites after closing and restarting Firefox?
If the latter happens then you have a problem with cookies that are not kept or the file that stores the cookies is corrupted.
Websites remembering you and automatically log you in is stored in a cookie that you must allow: Tools > Options > Privacy > Cookies: "Exceptions"
Make sure that you do not use [[Clear Recent History]] to clear the 'Cookies' and the 'Site Preferences'.
Make sure that you not run Firefox in [[Private Browsing]] mode.
In Private Browsing mode some menu items are disabled (grayed) and some features like visited links and others are disabled and not working.
You are in Private Browsing mode if you see "Tools > Stop Private Browsing".
