Connection Logic in SQL Developer?

Can anyone explain the design of the connection handling in SQLDeveloper?
You seem to get 2 sessions when you connect to the database ( maybe one for the browser and one for the worksheet ), and then one for every worksheet you launch afterwards, but when you close the worksheets , the connections don't seem to get closed.
Is this JDBC Connection Pooling - or is there some other design behind it - and how does it handle transactions?
This is using SQLDeveloper Production ( 1.0.0.14.67 ) on Win XP against a 9.2.04 database on Solaris, using the Thin Driver

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!

Typing letter doesn't skip to connection name in SQL Developer 1.5

When I open SQL Developer 1.5 and execute a query, a popup window lets me choose a database connection. In SQL Developer 1.2.1 and before, I could type a letter to jump to a specific name, similar to any dropdown menu. However, this doesn't work in SQL Developer 1.5, where I have to mouse click to find the connection. This keyboard functionality was very useful and should be put back. Thanks.

Yep... ur right... I can confirm this.

Sybase connection tab not showing in New connection option in SQL developer

Hi,
I do not see a Sybase connection tab in New connection option in SQL developer 2.1 where as it was available in ver 1.5
Why is that? how to fix it?

Hi,
Have you installed the JTDS JDBC driver yet into SQL Developer.
This is required before you get the connection tab for SQL Server and Sybase.
You can install the JTDS driver from the Check For Updates action.

Is it possible to disable Export connections functionality (Connections view) in SQL developer?

Hi,
because of some security reasons, there is a need to disable export connections functionality in SQL developer.
Is it possible to do this somehow?
Many thanks,
Dejan

Not that I know of.
Even if we did, they are still stored in a file that most of your users would be able to access.
You can however disable the ability to save passwords.
And exporting connections now do not include passwords by default, although you can include them if you supply an additional password.

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.

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.
Regards.

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.

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!

     Connection con= null; //connection create
          Statement stat = null; //prepared statement create

          try{

          while (rs.next()) {               // Position the cursor
                    // Retrieve the first column value
                    System.err.println("Name= " +rs.getString("Name"));

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.

Sue, thank you very much for the clarification.
I did update the C:\Program Files\sqldeveloper\sqldeveloper\bin\sqldeveloper.conf file file by appending the lines below and it solved the problem.

One last question.
How do I force SQL Developer to look at TNSNames. Currently I have to enter all info for each connection manually.
Thanks again.
