How could I unlock the account HR in Oracle SQL Developer?!

Hi Everybody! I am new with using ORACLE SQL Developer! and I just wanted ask how could I solve this problem: "ORA-28000 The account is Locked!" Please anyone can help me?? As I know, When you just need to make a new connection, you have to type "hr" as your username, and password! I hove done that many times, but it didn't work :(( I have also installed Oracle XE g11 and it seems that there is no problem with it, BUT my problem with the first program "Oracle SQL Developer!" PLEASE anyone can reply???

Hi,
Apparently you have both SQL Developer and Oracle 11g XE installed, but is not entirely clear if you know how to create a connection. If not, you should first read the SQL Developer tool's Help|Table of Contents|SQL Developer Concepts and Usage|Getting Started... help.
Or use the Documentation tab at http://www.oracle.com/technetwork/developer-tools/sql-developer/overview/index.html
Anyway, since you installed 11g XE, you should remember the password you picked for the SYS user. Launch SQL Developer, create a connection for SYS (whose role must be set to SYSDBA) using host=localhost, port=1521, sid=xe (these are all defaults and I doubt you overrode any of them). Once that connection exists, just follow Timo's instructions from his initial post. Let me repeat them, hopefully without typos, and in a bit more detail:
1) Open your SYS connection in the Connections view
2) Expand it, scroll down to the Other Users node in the tree
3) Right-click on the HR node, click on Edit User... from the context menu
4) Uncheck the Account is Locked checkbox in the Create/Edit User dialog
5) Click on the Apply button at the bottom of the dialog
or
1) Open your SYS connection in the Connections view
2) From the Worksheet, execute ALTER USER HR ACCOUNT UNLOCK
Now your HR connection should no longer display an account locked message when you try to open it.
Have fun,
Gary

ONLY the Carrier it is Locked to can unlock it.
No one here will know who that Carrier is.
The iPhone 3G can only run iOS 4.2.1

Edited by: user13373417 on 07-Jul-2010 09:06It appears you don't have a very clear understanding of how the client and the server are configured to communicate with one another.
============
A couple of important points.
First, the listener is a server side only process. It's entire purpose in life is to receive requests for connections to databases and set up those connections. Once the connection is established, the listener is out of the picture. It creates the connection. It doesn't sustain the connection. One listener, running from one oracle home, listening on a single port, will serve multiple database instances of multiple versions running from multiple homes. It is an unnecessary complexity to try to have multiple listeners. That would be like the telephone company building a separate switchboard for each customer.
Second, the tnsnames.ora file is a client side issue. It's purpose is for address resolution - the tns equivalent of the 'hosts' file further down the network stack. The only reason it exists on a host machine is because that machine can also run client processes.
Assume you have the following in your tnsnames.ora:
larry =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = curley)
)Now, when you issue a connect, say like this:
$> sqlplus scott/tiger@larrytns will look in your tnsnames.ora for an entry called 'larry'. Next, tns sends a request to (PORT = 1521) on (HOST = myhost) using (PROTOCOL = TCP), asking for a connection to (SERVICE_NAME = curley).
Where is (HOST = myhost) on the network? When the request gets passed from tns to the next layer in the network stack, the name 'myhost' will get resolved to an IP address, either via a local 'hosts' file, via DNS, or possibly other less used mechanisms. You can also hard-code the ip address (HOST = 123.456.789.101) in the tnsnames.ora.
Next, the request arrives at port 1521 on myhost. Hopefully, there is a listener on myhost configured to listen on port 1521, and that listener knows about SERVICE_NAME = curley. If so, you'll be connected.
What can go wrong?
First, there may not be an entry for 'larry' in your tnsnames. In that case you get "ORA-12154: TNS:could not resolve the connect identifier specified" No need to go looking for a problem on the host, with the listener, etc. If you can't place a telephone call because you don't know the number (can't find your telephone directory (tnsnames.ora) or can't find the party you are looking for listed in it (no entry for larry)) you don't look for problems at the telephone switchboard.
Maybe the entry for larry was found, but myhost couldn't be resolved to an IP address (say there was no entry for myhost in the local hosts file). This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe there was an entry for myserver in the local hosts file, but it specified a bad IP address. This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe the IP was good, but there is no listener running: "ORA-12541: TNS:no listener"
Maybe the IP was good, there is a listener at myhost, but it is listening on a different port. "ORA-12560: TNS:protocol adapter error"
Maybe the IP was good, there is a listener at myhost, it is listening on the specified port, but doesn't know about SERVICE_NAME = curley. "ORA-12514: TNS:listener does not currently know of service requested in connect descriptor"

Syncing an iDevice to a computer does not remove content from the computer.
Syncing an iDevice to a computer that it does not normally sync with will remove the content from that device.
If the media was acquired with a different Apple ID it is in no way linked to your Apple ID.

How can I unlock the copy protection of songs that I've acquired some years ago with an old - and non existing anymore - account? Can I link the songs to my new account or do I have to purchase them again?

How can I unlock the copy protection of songs that I've acquired some years ago with an old - and non existing anymore - account? Can I link the songs to my new account or do I have to purchase them again?

If you're in the US, you will be able to use iTunes Match for $25 a year to remove copy protection in a few months: http://www.apple.com/icloud/features/
If you're not, you can't. You can authorise iTunes with the old account in addition to your current account, so all your songs will play, but I'm not sure what will happen if you try to sync them to an iPod.

My phone was run over. It still works enough to see some of the screen but not the number pad. I cannot unlock the phone because I activated find my iphone. How can I unlock the phone so I can save my photos? Is there a way to unlock it from find my iphone. It was not backed up in iCloud. When I plug it into my computer, the computer tells me that I have to unlock it first. Help?

No I haven't synced my iPhone with the computer I'm currently using. The computer that I normally sync my iPhone with is being repaired.
I read a nearly identical question to mine (in which you answered) and I found my the answer. Thanks!
Now I have a few more questions: If I mail my broken iPhone to Asurion, will I be able to get my data off of my iPhone once Asurion has it? And what will happen to my old iPhone and the data on it if I activate my replacement iPhone? Will my broken iPhone just become de-activated and will the data be erased or lost or something? Could I still sync it (with the computer ir originally synced with) and back up the data?
Thanks.

Unlikely as you do not meet there requirements for unlocking.
Have your friend the provided the phone contact them. Based on your statements I am concluding he was or still is an AT&T customer, that is one of the requirements of getting the device unlocked.

"Ok, but Whats happen if the carrier said that I need the first contract personal information.."
Then you need the first contract personal information.
" I Know that all the companys have to unlock de phone... ¿?¿?"
Not true.
"Apple could help me then¿?¿? unlocking the Iphone beacuse Apple always have the last word...
No. Apple has no part in the decision ot lock or unlock at all. Lock/unlock is 100% the decision of the carrier. Apple has nothing to do with this decision.

If I have an old iPhone 4 that is not factory unlocked how could I unlocked? Don't want any anymore to jailbreak it

If I have an old iPhone 4 that is not factory unlocked how could I unlocked? Don't want any anymore to jailbreak it

I have looked around here. And I've actually in person helped a number of people clear a jailbreak from an iPhone and they work fine. The OPs biggest hurdle is likely to be the process of obtaining an unlock from the cell provider.
The mistake many people make is waiting to Restore until the unlock is approved. They should Restore prior to even getting the unlock approval then do it again after they receive it.
As most people know who have been here awhile we see the ones who have problems, not the ones who have successfully done the process.
If you go by ASC noone would ever buy an iDevice.

Can somebody tell me how could I unlock my disabled Iphone 5S?

Can somebody tell me how could I unlock my disabled Iphone 5S?

Restore the iPhone
This is covered in the manual and asked and answered on these forums many times each day.
Also a simple google search will find the apple article explaining how to do this.
