Can't connect to Database through JDeveloper with TNS connection

Hello there,
My work server we can connect to the server using TNS connection and it is working fine with Oracle SQL Developer that provide the type of connection. On the other hands, JDeveloper doesn't. I tried couple time to connect and I am unable to. Can someone tell me how to use a TNS type connection in JDeveloper?
Thank you.

I put server name for host name
From http://asktom.oracle.com
tell me what you consider to be the "server name". do you want the sid?
do you want the database name?
do you want the global database name? what is your concept of a "server name", we don't really have one
Ask Tom &quot;Server Name of the Oracle Database&quot;

How to Connect MySQL Database Through JTable?

Hi,
How to Connect MySQL Database Through JTable? anyone of u knows these concept please send me coding of that Part..
Thanks,
Guru..

Start by reading the tutorials. There's a section on Swing which shows you how to use tables and a section on JDBC which shows you how to use SQL.
And you can always search the forum as well since there are working examples of both posted on the forum.
If you need further help with a specific problem then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.
Don't forget to use the [Code Formatting Tags|http://forum.java.sun.com/help.jspa?sec=formatting], so the posted code retains its original formatting.

How to connect 10g database through Enterprise manager???

Hi All,
I want to connect the database through Enterprise manager.
My database is on 10g. Version is 10.1
Please tell me the procedure to connect the database through E.M.
Thanks and Regards,
Prathamesh.

Are you thinking of the Enterprise Manager supplied with Oracle9i? If yes - it doesn't work quite that way ... and the 9i java OEM is not compatible.
Use the enterprise manager supplied with the 10g database, called the dbconsole (look for a service or start it using 'emctl start dbconsole') and access it using http://{localhost}:5500/em
If that doesn't satisfy you, load the updated version of the OEM 9i java standalone from the 10g client disk.

How to connect sybase database in JDeveloper 11g using JConnect

Hi
How to connect sybase database in JDeveloper 11g using JConnect? Please help.

User,
It would help if you explained Sybase Jconnect instead of leaving us to google.
At any rate, it appears you need to create a library definition in JDeveloper, add the appropriate JConnect JAR files to the library's classpath, and then add the library to your project.

Turn off your printer.
Go to System Preferences > Print & Scan > Printers window and delete the printer from the list, then add it back.
Turn on your printer.
Any difference?

Failed to connect to database instance: ORA-12541: TNS:no listener

Hello -
This is the error in grid alert:
Failed to connect to database instance: ORA-12541: TNS:no listener (DBD ERROR: OCIServerAttach).
But the test of connection string in database configure screen is successful. tnsping works too.
Grid version: 11.2.0.1.0, no patches.
Target database version: 10.2.0.2
Connect string: (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST = s08) (PORT = 1528))) (CONNECT_DATA = (SID = S08) (GLOBAL_NAME = S08.WORLD)))
Any ideas?

OK.. Are you testing the connectivity from "Preferred Credentials " setting page?
Try to configure target from
Targets-->databases--> then select your database and click on "configure" button.
Enter all the details and press "Test Connection" button once it shows that connection is successful go to next page and finally save the setting.
Let me know how it goes....

Odbc connection test success but can't link the database to oracle with 1013 call failed error.

i am using my MS Access 2013 to connect with my oracle database. I created the odbc link and successfully have connection test pass. However i can;t link the database with my MS access. When i am using different software (mapinfo), i am able to connect to oracle database. The error is"1013: user requested cancel of current operation"

In MS access, i open the external data and select odbc. Select my odbc link created previously, enter the password and after a while the error message pop up.
But if i am using another tools, such as SQL Developer or Mapinfo, i will able to connect to oracle database using the same odbc link.

How to connect Oracle database through Microsoft ODBC?

My ODBC Configuration:
DSN name is :db
Username : india
Server :db.world
Now, i am trying to connect with oracle database through SQL*plus or TOAD.
But, it is giving the following error.
ORA-03121: no interface driver connected - function not performed
Database version : 9.2.0.1.0
Operating System : Microsoft Windows XP
ODBC Version : 2.575.1117.00
I am trying to connect with the database like this:
Username : india
Password : india
Database : ODBC:db
Can i connect like this otherwise whether i need install any other supporting driver?

Now, i am trying to connect with oracle database
through SQL*plus or TOAD.
But, it is giving the following error.
ORA-03121: no interface driver connected -
function not performed
I am trying to connect with the database like this:
Username : india
Password : india
Database : ODBC:db
As already stated, you can not use the DSN in SQL*Plus (nor TOAD, afaik)!
I can reproduce the error message with the following:
C:\>sqlplus a/b@ODBC:c
SQL*Plus: Release 11.1.0.6.0 - Production on Mon Aug 4 21:34:58 2008
Copyright (c) 1982, 2007, Oracle. All rights reserved.
ERROR:
ORA-03121: no interface driver connected - function not performedLooking up the message, it says:
Cause: A SQL*Net version 1 prefix was erroneously used in the connect string
Looks like this has nothing to do with your DSN - it is more a matter of not using a proper connection string.
If 'Test Connection' works then you should probably proceed to work with Crystal Reports, using the DSN in question.
However, you should note that the old MS ODBC driver for Oracle was designed for OCI 7 (and for databases 7.x-8.x) and is now considered obsolete by both MS and Oracle.
Deprecated MDAC components and MS KB Article 244661.
Use the Oracle ODBC driver included with a supported Client version instead.
Edit:
Clarifying and adding references.

Go to System Administration
-> System Configuration
-> System Landscape
-> select a Folder where you want to store your system object
-> right click -> New System
-> in the wizard, select JDBC System
-> enter values
-> edit
Then fill in the correct values as stated here:
http://help.sap.com/saphelp_nw04/helpdata/en/84/d5df3df2ad685ae10000000a11405a/frameset.htm
Then assign an Alias and enter some usermapping data for the system.
You then can use the ConnectorService to get a native sql connection and fire statements. I'm sure you can find some examples here.
