SQL Developer-Cannot Connect

Hi, I have the same problem as the person who posted the question
The history is i already have oracle 10g express edition installed on my system but with it I cannot create tables or execute DML or DDL commands so I downloaded SQL developer .
When it came to the connection I wanted to fill in the Hostname , Port and SID in that order it gave me that same error "The network adapter could not establish connection ", and to fill in those spaces I used the link I saw when opening the Human Resources schema in the express edition(The schema came in the express edition and I used it to learn the SELECT statement). so i tried to use that address and it came in this format :- http://127.0.0.1:8080/apex/f?p=4500:1000:3171371893604961
And since SQL told me to fill those parameters as Hostname:Port:SID I felt the use of the last 3 digits i.e 4500:1000:3171371893604961 would have worked but that is what is giving me the error.
I would appreciate the help. Thank you

SQL Developer (Cloud connections) to Cart not working

I follow the QBE execise along with Oracle Public Cloud. Why nothing happend when I drag/drop tables in SQL Developer (Cloud connections) to Cart?

Can reproduce same issue in 11gR1.. DIFF works fine in 10gR2.
I noticed that 10gR2 allows something like:
DBMS_METADATA.SET_TRANSFORM_PARAM(th,'SEGMENT_ATTRIBUTES',0);
and 11GR2 returns error similar to error SQLNAVIGATOR returns while running diff:
DBMS_METADATA.SET_TRANSFORM_PARAM(th,'SEGMENT_ATTRIBUTES',0);
end;
Error report:
ORA-31600: invalid input value 0 for parameter SEGMENT_ATTRIBUTES in function SET_TRANSFORM_PARAM
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 105
ORA-06512: at "SYS.DBMS_METADATA_INT", line 8424
ORA-06512: at "SYS.DBMS_METADATA_INT", line 9484
ORA-06512: at "SYS.DBMS_METADATA", line 3950
Its safe to assume that this is SQLDEVELOPER bug. Hope it will be addressed sometime.

SQL Developer - database connect problem

Hello
Just wanted to give SQL Developer a try, downloaded it, unzipped and pointed at Java SDK's java.exe.
It started, I created a TNS connection and successfully passed test. But when I try to connect to database - it errors with following
java.lang.ArithmeticException: / by zero
     at oracle.jdbc.driver.OraclePreparedStatement.<init>(OraclePreparedStatement.java:1233)

I googled for this error and found nothing suitable
Other development tools including SQL Plus connect an run fine.
I have 10g client, and I connect to 9.2.0.6 database. My OS is Vista Business SP1, so I though it might be UAC issue and tried running as both standard user and administrator, also allowed java.exe and sqldeveloper.exe through firewall. Nothing helped :(
Any settings and ideas that might help will be appreciated.
Thanks for help

SQL Developer not Connecting to Oracle after Updating java

Hi,
I am using Oracle 11gR1. Windows XPsp2 OS. Earlier Sql Developer was connecting successfully to Oracle , but when i updated my java Runtime to 'Update 17' (Of version 6), I am getting problem...Something like vendor problem error(tried to connect many times, also restarted system...but same problem persisted).
BUT, at this time when i am writing this problem, I though to check again that problem and get that actual error message....but surprisingly now that error is resolved automatically as if something magic has happened...
I am continuously connected to internet for last 5 hours.
SO, WHAT WAS THE PROBLEM , AND HOW IT IS RESOLVED AUTOMATICALLY?

Hi ,
once again the same problem. Again i am not able to connect to Sql Developer environment. My JRE is updated to update 18, since then again i am facing the same problem.what could be the possible solution?
The exact error message is "An error was encountered performing the request operation:Io exception:The network Adapter could not establish the connection vendor code 17002"
Thanks

I suspect work of SQL Developer after connect

what want about work of SQL Developer after connect ?
Thank you very much

Not really my area, and not really a SQL Developer question, but it's using a standard Java SQL connection in this case.
If you do not supply the DNS suffix (perhaps as a suffix to the host or service name), then it must get it from somewhere, probably some OS configuration. For example, on Win XP, I see this from a Cmd console window...
ipconfig /all
Windows IP Configuration
        Host Name . . . . . . . . . . . . : <myhostname>
        Primary Dns Suffix . . . . . . . : us.oracle.com
        Node Type . . . . . . . . . . . . : Hybrid
        IP Routing Enabled. . . . . . . . : No
        WINS Proxy Enabled. . . . . . . . : No
        DNS Suffix Search List. . . . . . : us.oracle.com
...Hope that helps (and corrections welcome),
Gary

SQL Developer - Cannot see list of tables in my connection

Hi - when I downloaded and started to use the SQL developer tool, once I connected, I could see all of the tables/columns in my connection on the left side of the tool, and I had my query panel, results panel, and SQL history stacked on the right. Suddenly something has changed, and I cannot see the list of tables, etc. in my connection anymore, so I have to rely on memory and SQL history to remember the table and column names. It has to be "hidden" somehow, but view-connections does not help, and trying to click and drag windows doesn't uncover it either.
Any suggestions?
Thanks!

Probably better to ask in the SQL Developer forum here: SQL Developer
I've been trying the version 2 beta though and it has quite a few bugs in. Table browsing is working fine for me, but all my functions and procedures have disappeared from the tree view. It does odd things with code formatting too.
I don't think it will be supplanting trusty old command line SQL Plus for me yet any time soon...

SQL Developer cannot execute multiple queries in one connection

Hi,
Using : SQL Developer 1.2.29.98, Oracle Database 9i on Windows XP.
Currently I have TOAD and PL/SQL Developer to handle things related to Oracle Database.
I found this SQL Developer tools as an interesting tool which might replace PL/SQL Developer (I assume).
I opened two SQL Worksheets and tried to execute 2 queries (time consuming one) simultanously, suddenly it freezes (the window become grayed). Just like TOAD, we cannot smoothly execute multiple queries on single connection on SQL Developer
I can monitor the query process using TOAD (Session Browser) and found both queries are running while SQL Developer window become grayed and seems not functioning. After the queries have been finished, I mean both of them, the SQL Developer window become normal and "alive" again showing the expected results.
Well, however PL/SQL Developer could handle this. Executing multiple queries in single application is just its unbeatable features.
We can view the query result once its finished instead of until the others being processed, by just only switch the SQL Windows.
Is it true that SQL Developer doesn't support executing multiple queries?
Or is it a feature which we should request?
Or we have to activate this feature by doing some changes on configuration / preferences?
(Do we need to open two SQL Developer instances? what a memory consuming solution).
Regards,
Buntoro

SQLDeveloper connections are single threaded and also rather single minded (in that you can't do much else while a long query is running.)
There is an existing feature request http://apex.oracle.com/pls/otn/f?p=42626:39:3685254426061901::NO::P39_ID:4202 for which you can vote.
The workaround is to have multiple connections. Not brilliant but it works.

Error in SQL Developer: Database Connections has no JNDI context so cannot

Hello,
I have installed SQL Developer 3.1.07 version on Linux. Previously I was able to create a connection and browse the existing tables, add tables, etc.
Now when I launch SQL Developer, I see that no connections are displayed. Instead there are these three messages indicating an error. Can you please advice on how to resolve this?
Thanks,

Hi uparthas,
Here is a similar thread (Windows 7) marked as answered, and may be applicable to a Linux environment if you are using jdk1.7 rather than jdk1.6:
Lost my connections.
If that does not solve the issue, you might also wish to ...
1. Exit SQL Developer
2. Delete or rename the /home/user/.sqldeveloper/system3.1.07.42 directory
3. Launch SQL Developer, perhaps without choosing to migrate settings from a prior install.
Hope this helps,

SQL developer cannot see connection info from tnsnames.ora file

Greetings All,
I have been using sql developer for a while. Currently on 3.0.04.34.
I have 16 database connections.
Everything was working fine until yesterday.
Today when I tried to connect to a database from the list of connections I am getting following error:
Invalid connection information specified. Verify url format for specified driver.
When I pull up the property for this connection -connection type is still TNS, Netwrok Alias is now greyed out and what was in Netwrok Alias has shifted to Connect Identifier.
When I try to create a new connection I do not see entry from tnsnames.ora file for the databse I am trying to connect to in the Network Alias drop down list.
I can connect to this database from sqlplus.
Has anyone seen this behavior? Does any one know the fix for this?
Thanks.

Hi,
Maybe your preference settings got corrupted, or the Tnsnames.ora file got moved to somewhere SQL Developer can't find it.
Are you using either:
1. Tools|Preferences|Database|Advanced|Tnsnames Directory, or a
2. TNS_ADMIN environment variable
to point to your Tnsnames? Having one of those should enable the Network Alias drop-down list to get populated. Otherwise, if the values moved to Connection Identifier are correct, then you won't be to connect in that mode without also having an Oracle client installed with an 11.1 JDBC thick driver (ocijdbc11.dll).
If there is no issue with the Tnsnames. ora location, it might be a good idea to use Export Connections to make a backup of your connections. Then you can try deleting the connections from SQL Developer and re-importing them. Even if that doesn't fix the problem, you should be no worse off.

Gary

SQL Developer Problem: Connect Database Windows Wont Show

Hi,
I have Windows Vista Home Basic and I have installed Oracle XE 10g which works great. However, I need to install SQL Developer too but it wont work. I think it may be a compatibility issue, or else some problem with Java. The thing is that no matter how hard I've tried I couldn't beat all the problems I had with the interface. First of all, when I try to make a new Database connection, the option window won't show. Second, when I enter in Preferences, I cannot choose anything but the general option. Also, I don't know where is the connection window.
I would appreciate all the help you can provide. Trying to start with my school project....
Have a nice day. Thanks in advance.
Mikywan.
P.S.: Sorry about my english.

I add these lines at <sqldeveloper>\ide\bin\ide.conf and worked.
AddVMOption -Duser.language=en
AddVMOption -Duser.country=US

Sql Developer not connecting to the DB

Hi
I have latest Oracle Sql Developer 3.2.1 installed, and I cannot connect to database Oracle 11g Enterprise Edition.. I typed correct SID, port number, user and password and it won't connect saying: "The Network Adapter could not establish the connection. Vendor code: 17002"
Strangely I am able to ping and telnet to the Database machine with the DB port
ping <hostname> got reply
telnet <hostname> <port> got connected.
The TNS Listener of the Database is up as I am able to connect to the DB from another computer.
Do we need to setup anything extra to connect to a DB?
Thanks in advance

Hi,
Item 4 in the following relies on my Windows 7 environment variables. Did you also try...
1. lsnrctl status
2. lsnrctl services
3. tnsping <tnsalias>
4. sqlplus sys/<pswd>@//%COMPUTERNAME%:<port>/<sid>.%USERDNSDOMAIN% as sysdba
The syntax in (4) requires specification of the SERVICE_NAME rather than the SID.
My fully qualified SERVICE_NAME happens to be <sid>.%USERDNSDOMAIN%
My fully qualified hostname is %COMPUTERNAME%.%USERDNSDOMAIN%, but %COMPUTERNAME% also works for me.
See if using the literal values of these variables in the SQL Developer connection definition helps.

Gary

How do I get SQL Developer to connect to SQL Server.

I have downloaded SQL Developer but I see no option to connect to SQL Server in order to do the database migration. I found a document that said to download the MSSQLSERVERMIGRATION.ZIP file and it said to unzip the file. There is no instruction as to where the files are going. Can someone point me in the right direction?

Hello,
did you read the following from the SQL Developer online help:
Before Migrating From Microsoft SQL Server or Sybase Adaptive Server
To configure a Microsoft SQL Server or Sybase Adaptive Server database for migration:
Ensure that the source database is accessible by the Microsoft SQL Server or Sybase Adaptive Server user that is used by SQL Developer for the source connection. This user must be able to see any objects to be captured in the Microsoft SQL Server or Sybase Adaptive Server database; objects that the user cannot see are not captured. For example, if the user can execute a stored procedure but does not have sufficient privileges to see the source code, the stored procedure cannot be captured.
Ensure that you can connect to the Microsoft SQL Server or Sybase Adaptive Server database from the system where you have installed SQL Developer.
Ensure that you have downloaded the JTDS JDBC driver from http://jtds.sourceforge.net/.
In SQL Developer, if you have not already installed the JTDS driver using Check for Updates (on the Help menu), do the following:
Click Tools, then Preferences, then Database, then Third Party JDBC Drivers.
Click Add Entry.
Select the jar file for the JTDS driver you downloaded from http://jtds.sourceforge.net/.
Click OK.
For further reading I recommend to start on this page:
http://www.oracle.com/technetwork/database/migration/sqlserver-095136.html
It contains a demonstration "Creating a connection to Microsoft SQL Server".

Around a month ago, a similar question appeared on Jeff's block... look for checkText in http://www.thatjeffsmith.com/ask-a-question/
There was no resolution there, so (as the SQL Developer code in that area has not changed) I would tend to think it might have something to do with
1. Your Locale affecting the Formatter class's parsing of that pattern; or
2. A bug in the jdk version in use, probably also related to the Locale.
I recommend upgrading to the latest jdk1.7.0_xx update. If that does not solve the issue, then try changing the Locale.

Problem in sql developer while connecting to oracle 11g

when am creating a database connection with oracle 11g in sql developer editor it s throwing network adapter could not establish the connection
connection name test
user name system
password system
Role default
Host name localhost
Port 1521
SID orcl
Can any one help me to resolve the problem?
Thanks in advance

Those parameters probably aren't correct.
Is that 11g on your machine? Try to specify the real IP instead. And sure the listener is up?
Also sure about the SID and port?
Hope that helps,
K.
