Configuring RAC-aware JDBC connection in Oracle SQL Developer?

How can Oracle SQL Developer be configured to properly connect to an [Oracle RAC|http://en.wikipedia.org/wiki/Oracle_RAC] environment, I.E., not just setup to always connect to one of the individual nodes?
[http://programmersjournal.blogspot.com/2008/08/jdbc-connection-string-for-oracle-rac.html] has an example of a classic and the equivalent RAC-aware version of a JDBC connection string. I've already been using a RAC connection string of the same format from within custom Java applications without issue. I thought the same should be configurable in Oracle SQL Developer by setting the "Connection Type" drop-down to "Advanced", then entering the RAC-aware JDBC connection string as the "Custom JDBC URL". However, upon testing the connection, the following error is displayed at the bottom of the dialog:
Status : Failure -Test failed: Io exception: NL Exception was generated
There is no additional information shown on the "Logging Page" view. Using Oracle SQL Developer 1.5.5.
Thanks!

Thanks, Barry. Just F.Y.I., it is working for me now that I upgraded to the 2.1 EA as -K- suggested. I had marked his reply as "Correct", but probably should have left a response indicating my success as well.
Now, if there's anything you could do regarding the [issues around the display performance of CLOBs, etc., in the Query Result view|http://forums.oracle.com/forums/message.jspa?messageID=3906571] , it'd be very appreciated!

Did you perhaps do a custom install? The DB software includes a version of sql developer and, by default, installs it in the sqldeveloper folder of the DB_HOME. Does that folder have sql developer in it?
I suggest that you NOT use the version of sql developer that ships with the database. That version will NOT be the current version.
Download the current version of SQL Developer, unzip it into a new folder and create a desktop icon for it.
http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html
The current version includes many, many bug fixes from that earlier DB version and you will have far fewer probems with it.

How to connect from oracle sql developer ?

I've made one java class, to access UserRecord Data Base from sql developer.
My class file is :-
import java.sql.*;
import java.io.*;
public class SelectData{
public SelectData(){}
public void selectData(){
          String url="jdbc:oracle:thin:@10.1.236.10:1521:dev92i";//connection url
     Connection con= null; //connection create
          Statement stat = null; //prepared statement create
          ResultSet rs=null; //result set to hold result
          try{
          Class.forName("oracle.jdbc.driver.OracleDriver");
          con = DriverManager.getConnection(url,"scott","tiger");
          stat = con.createStatement();
          rs = stat.executeQuery("select Name from UserRecord");
          while (rs.next()) {               // Position the cursor
                    // Retrieve the first column value
                    System.err.println("Name= " +rs.getString("Name"));
                    // Retrieve the first column value
                    System.err.println("Pswd= " +rs.getString("Password"));
          rs.close();

          finally{
                    try{
                    if(con!=null)
                         con.close();
                    catch(Exception e){
                         System.err.println(e.getMessage());
public static void main(String args[]){
     SelectData sd=new SelectData();
     sd.selectData();
When i run this class file it gives error :-
"oracle.jdbc.driver.OracleDriver"
Plz help me out from this problem and suggest any configuration if required in oracle sql developer to run my programs.

{color:#0000ff}hi,
add the jar for oracle jdbc to the libraries.
if you are using any IDE then just change the project properties adding the jar file.
if not edit the classpath of the envoirnment variables.

Able to connect via Oracle SQL Developer, but not sql plus

Using Oracle 10.2.0.
I can connect using the TNS connection type in SQL Developer, but cannot do so in SQL PLUS. SQL Plus gives me the error -- could not resolve the connect identifier.
When I do tnsping USPO_ADHOC, I get:
C:\oracle\product\10.2.0\client_1\network\admin\sqlnet.ora
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION =
TNS-12533: TNS:illegal ADDRESS parameters
So here is my tnsnames.ora file:
INTL_ADHOC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.239.162.108)(PORT = 1521))
(CONNECT_DATA =
(SID = intl1)
USSYN_ADHOC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.239.162.109)(PORT = 1521))
(CONNECT_DATA =
(SID = USSYN)
USPO_ADHOC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.239.162.107)(PORT = 1521))
(CONNECT_DATA =
(SID = uspo)
Any assistance gratefully appreciated. Thanks.

I actually did not have that environmental variable, so I added it, but nothing changed.
I would note that if I do tnsping foo, I get: failed to resolve name.
If I do tnsping USPO_ADHOC, I get: illegal address parameter.
In both cases, the output correctly identified the path to my sqlnet.ora file, which is in the same directory as my tnsnames.
So I would conclude from that, that the system was already able to find my tnsnames file.
Anyway, here's my sqlnet.ora:
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
Thanks again for any ideas!

Create connection with Oracle SQL Developer

Hello,
my test to connect my Oracle database with SQL*PLUS works. Here I need only the username (I test with system), my password and the hostname (orcl).
Now I want to create this connection with the SQL Developer.
Here I need the Port. I don't know the port of my database. How can I find it out?

Hi, the port must be the used by listener, review the $ORACLE_HOME/network/admin/listener.ora file or get the listener status(lsnrctl status) for get the correct port.
You can try with the default port. (1521).
Luck.
Havea good day.

Problem in connection to Oracle SQL Developer

Hi All,
I am trying to connect to remote machine database through Oracle SQL Developer, it is giving me teh following error.
Status: Faliure -Test failed :io connection :The Network Adapter could not establish the connection .
I had given the hostname as the name which is assigned to that server, it didnt work.
Later i tried with the IP address of the Server, it worked.
Can anybody tell me how can i connect by giving hostname instead of the IP address.
Thanks in advance,
Vinay

Hi Vinay,
One way would be to add an entry in your hosts file. On windoze you can find this in
%SystemRoot%\system32\drivers\etc

Unable to register a new cloud connection in Oracle SQL Developer

Please somebody can assist me how could I connect the new cloud connection
I have used the port 22 and SFTP user and host are all ok .. but the error which comes up when i try to connect is
"Peer not authenticated"
Please help!!

Hi Ankur,
Thanks for the updates. You've mentioned you're on Windows - is it 32-bit or 64-bit?
+> I want to confirm that the user id asked in the popup for the new cloud connection , needs to be made in the Application Express in the online database service or is it User Id of the administrator?+
As mentioned in the white paper:
"In order to perform these steps, the data load process uses two different users – one user defined for the Secure FTP (SFTP) site, and another defined to load the data in the Database Cloud Service. You can use any user who is a Service Administrator or Database Developer to load data into your Database Cloud Service. The SFTP user for your Database Cloud Service is identified in the My Services portal1 for the Database Cloud Service in the section label Service SFTP Details."
So the user login credentials you enter in the popup for the new Cloud connection should be "any user who is a Service Administrator or Database Developer". In the 'Welcome to Oracle Cloud' email that you received upon trial registration, the user defined under the 'Identity Domain Account Details' is your default Service Administrator. However, you can of course create additional Service Administrator users or indeed Database Developer users via the Identity Console. Log in to MyServices Administration URL (you'll find the URL in the 'Welcome to Oracle Cloud' email that you received upon trial registration), then select your database service, and click on the Identity Console button on the Services page. This will launch the IDM console, where you can manager the users and roles for your database service. To add a new Database Developer user, for example, you can do the following in Identity Console:
1) Click 'Manage Users' link from the left hand side bar
2) Click Search. You should then see a list of the existing users for your service. Among those users, you'll see your SFTP user. Ensure that you have reset the password for your SFTP user, as per the documentation.
3) Click Create, and enter the credentials for a new user
4) Upon successful creation of your new user, click 'Manager Roles' link from the left hand side bar
5) Click Search. You should then see a list of available roles for your service.
6) Select 'database Database Developer' from the list of available roles, and then click Assign.
7) In the Grant Role popup dialog, and click Search.
8) From the list of available users, select the new user you created in step 3 above. You'll now have a new Database Developer, whose credentials can be used in the creation of a Cloud Connection in SQL Developer.
Now in SQL Developer, ensure that your new Cloud Connection uses the following settings:
Database Username: <enter name of user created in step 3 above OR enter your Service Administrator name>
Database URL: <copy the "Service Home" URL from your 'Welcome to Oracle Cloud' email, and paste it here> e.g. https://database-trial_name.oraclecloudapps.com/apex/
SFTP Username: <enter name of your SFTP user, which you'll find on the Overview page in MyServices> ** you should have already reset the password for this user via Identity Console
SFTP Hostname: <enter the SFTP host name, which you'll find on the Overview page in MyServices>
SFTP Port: 22
When you attempt to connect to that new Cloud Connection, enter the username/password combo for the user you defined in 'Database Username' of the connection properties. My tests are on Windows 32-bit, and I've experienced no issues connecting using either my Service Administrator or Database Developer login credentials. So I'd be interested to find out whether you're running on 64-bit, which could potentially explain why you're seeing different results. Apologies if the above is overkill, but I figured it was worthwhile outlining the information for other interested parties viewing this thread too.
Regards,
Hilary

TNS connection in Oracle SQL Developer

We have been using TNS connections in SQL Developer. Today we moved a database to a new server but still used the same TNS alias in tnsname.ora file for the database. However, the tns connections in SQL Developer shows this alias still points to the old database host server, therefore unable to connect. There is only one tnsnames.ora file on my PC and I have TNS_ADMIN set up to point to it. But it seems to me SQL Developer does not read this altered alias, but used some kind of "cached" alias which points to the old host. If I add a new alias in tnsnames.ora file, it reads correctly. But it does not refresh an existing alias.
So how is this "Network Alias" dropdown list populated? Even after I delete tnsnames.ora file, the drop down list still not changed. How do I reinitialize this list?

Hi,
You should try and search SQLDeveloper help for TNS, that would give you some clues.
The list for selecting a network alias is initially filled from the tnsnames.ora file on your system, if that file exists.
Connections are stored in IDEConnections.xml.

Peter

Oracle SQL Developer does not browse Sybase's objects

I had installed and configured jtds-1.2.5.jar in Oracle SQL Developer for Sysbase connection. Oracle SQL Developer does not browse any objects. Why? Can you please provide a solution?

Hi,
Can you provide some more information into what you are experiencing.
What version of SQL Developer are you using?
Did you install the jtds jar under the
Tools > Preferences > Database > Third Party JDBC Driver
Is the Sybase tab available in the new connection dialog?
Did you select the default database in the connection dialog?
Can you run a query against the Sybase database from the SQL Developer worksheet?
Note that JTDS 1.2 is the only supported version. There maybe issues with other versions.

Dermot.

Accessing MySQL InnoDB tables via JDBC using Oracle SQL Developer

I had posted a problem in the Oracle SQL Developer forum with how that application (v1.1) accesses MySQL InnoDB tables and someone replied that the "[data migration] team created the integration with MySQL", so I am posting here in hopes of learning more about the problem.
Here's a summary:
When I use Oracle SQL Developer to query MySQL InnoDB tables, I need to issue a "commit" before I do each query to ensure that I am getting current results. Otherwise, it appears to be using a snapshot as-of the last commit. Is this a problem with SQL Developer, or a JDBC configuration, or MySQL problem even?
The full details are here:

Oracle SQL Developer Connection Help

Hi,
I'm a complete Oracle newbie, so please bear with me. I've been doing research on protein clustering and at my lab the SQL developer has been running queries that I can then do statistics on. I have the query that I need to run, and was told to download Oracle SQL Developer and Oracle Client.
I was also given a username and password, a hostname, a port and a SID. I'm a bit confused, do I still need to install Oracle Client? And if so, I can't quite find what it is on the website? I have SQL Developer installed but when I click connect I get:
"Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection"
I'm pretty computer literate outside the world of databases so if someone can offer some explanations and guidance, it would be appreciated!
Thanks!

Thanks!If you have SQL Developer installed & need to connect to some Oracle DB,
then you do NOT need Oracle client.
FWIW - SQL Developer is written in Java & uses JDBC (thin) to connect to the DB
Is the DB Server on a subnet local to your system?
