SQL developer (3.1.06.44) connection issue

When I try to connect the database I'm getting below error, what could be the problem...Can any one help me ...?
Connection type : Basic , Role : SYSDBA
Port : 1521

Staus: Failure - Test failed : The network adapter could not establish the connection

Hi 889828,
It is a fairly generic error.
Is your database Started? ( On Windows XP service name: OracleService<name> )
Is there a firewall (on the client or the server) blocking the connecton? (try telnet to 1521)
Does SQLPLUS work (through a tcp network alias in tnsnames.ora)?
Does tnsping work ?
Are all your arguments typed in correctly?
I did a quick look for similar messages:
java.sql.SQLException: IO Error: The Network Adapter could not establish...
Exception: IO Exception:Thenetwork adapter could not establish connection.

SQL Developer MSSQL 2012 to Oracle 11GR2 issues

I have an instance of SQL that I want to migrate over to Oracle 11G R2 as a POC. I was playing with the SQL Developer tool and was able to connect to both of my instances. However during the "Migrate to Oracle" function I am getting an error. With the SQL Dev 3.2.2 I was using jdk1.6.0_45 and jtds-1.2.jar. So I decided to install SQL Developer 4 to see if there's any other issues. With SQL Dev 4, I was using jdk1.7.0_25 and jtds-1.3.1.jar, which also errored out. Now the question is... how do I migrate? On the Step 4 of 10, "Source Database", when I choose the SQL instance and click next I get the following error:
java.lang.NullPointerException

SQL developer 3.0 - Few Query Builder issues

Hi All,
I have just started using SQL Developer 3.0 so have not fully browsed thru all of the available options in SQL Developer. I have been trying to work on creating and editing sql statements using Worksheet and Query Builder.
I am working on to test this tool so I can give it to the users for them to try and use it - they used to work on the old Query Builder 6.0.7....since it is already de-supported long back to work against 11g database, I am hoping to tell them to use SQL developer 3.0 instead.
Hence, if an user doesn't know how to write a sql statement, he/she would try to do the same using Query Builder.
So, the following questions are more aligned towards a normal user who would try to create a query in the Query Builder window, instead of directly typing a sql statement in the Worksheet window.
1) How to establish/create a relationship between tables after you have dragged down the tables into the Query Builder window? - i tried but couldn't get any options!.
2) Sometimes I see 'Connection closed' error when i try to run a query. How to refresh the connection without opening a new Connection tab?
- I tried this but evertytime it opens up a new connection tab, while the old tab is still present.
3) Columns in the Expression field in Query Builder window can ONLY be displayed in the result set, if the 'output' box on the extreme left of the 2nd section in Query Builder window is checked.
Now when i try to check the output box for an expression (with few aggregate functions), the 'Grouping' check box automatically gets checked, which when run throws an ORA-00934 error: group function is not allowed here...but when I de-select the 'Grouping' check box, the 'output' box also gets un-checked!.
How to solve this out?
Please let me know the resolutions of the above - much appreciated.
With Regards,
Pamir

Hi,
As Raghu noted above, and you also saw in rp0428's following reply,
Re: Problem with displaying sdo_geometry objects
drilling down to the cell edit details is your only recourse for now. Apparently there will be further work done in this area, but it is not clear exactly what or when it will be. For those with access to it, here is a bug reference:

SQL Developer 3.1 EA - Database Diff Issues

Hi
I am using SQL Developer 3.1 EA to generate database difference script to upgrade my db. This is really very useful and very good tool for compare two different databases and generate the difference script.
There are few bugs (?) identified while using database diff tool.
1. If there is a column mismatch in Source and Destination tables, directly drop the table and recreate new one. This is not a good solution for upgrading database with some other database (data loss is the major issue). Microsoft handled this situation in VS2010 to create temp table with new structure then move data to the temp table and finally drop the original table and rename temp table to original. I am expecting the same method in Database Diff also.
Sample Code:
--Changed TABLE
--F_SYSTEM_2
DROP TABLE "ED9461001ER09_D1"."F_SYSTEM_2";
CREATE TABLE "ED9461001ER09_D1"."F_SYSTEM_2"
(     "SYS2_SEQN" NUMBER(9,0) DEFAULT 0 NOT NULL ENABLE, ....
2. Primary key constraint created with table creation for new tables. But late point of time, Create unique index statement also trying to create the same to lead runtime error.
Sample Code:
--New TABLE
--F_SYSTEM_3
CREATE TABLE "ED9461001ER09_D1"."F_SYSTEM_3"
(     "SYS3_CORVU_DB_NAME" VARCHAR2(50),
     "SYS3_CORVU_DB_SCAP" VARCHAR2(8),
     "SYS3_CORVU_DB_VIEWURL" VARCHAR2(2048),
     "SYS3_CORVU_HP_NAME" VARCHAR2(50),
     CONSTRAINT "PK_F_SYSTEM_3" PRIMARY KEY ("SYS3_SEQU") ENABLE
--New INDEX
--PK_F_SYSTEM_3
CREATE UNIQUE INDEX "ED9461001ER09_D1"."PK_F_SYSTEM_3" ON "ED9461001ER09_D1"."F_SYSTEM_3" ("SYS3_SEQU");
3. If there is an difference in procedures, script generated with two Create Procedure statements (Source and Destination) which is irrelevant.
--Changed PROCEDURE
--GET_DI_COUNT
CREATE OR REPLACE PROCEDURE "ED9461001ER09_D1"."GET_DI_COUNT"      (PP_SEQU int,
--Changed PROCEDURE
--GET_DI_COUNT
CREATE OR REPLACE PROCEDURE EDISAPAC10_D1.GET_DI_COUNT      (PP_SEQU int,
I am expecting your solution / clarification.
Regards
Nagarajan Santhan

1. Makes sense. You can request this at the SQL Developer Exchange, so other users can vote and add weight for possible future implementation.
2. Long standing bug. As it won't make your computer explode, apparently low priority to fix.
3. I'm unable to use the comparison feature in EA3. I do get the progress dialog comparing the different procedures and functions, but when finished it just disappears, and no comparison sheet opens, like the whole operation just got cancelled. No exceptions in the console, just a lot of these in the logging page:
update returning false for Grid1oracle.ide.Context[{Context.WORKSPACE=Databases.jws, Context.PROJECT=IdeConnections%23DES+-+Reddis.jpr, Context.SELECTION=[Loracle.ide.model.Element;@1353c19, Context.EVENT=null, Context.VIEW=LoggingMessagePane.Logging Page}]Can someone from the team suggest something to debug?
Thanks,
K.

SQL Developer 1.1 Crash on connecting

Hello,
I have a TNS type connection defined which uses the default role and a connect identifier rather than a network alias. When I click test I get a success message but when I click connect then SQL developer waits for a few seconds and then crashes (no error message displayed). Can anyone suggest where to start looking for the cause of this?
Regards

I found another post by jayantp from 8-dec-2006 where he suggested copying some files from the oracle client jdbc\lib directory to the sqldeveloper\jdbc\lib directory:
ojdbc14.jar and
ojdbs14dms.jar
This works for me but I don't know what the side effects might be. Any thoughts?

Oracle SQL developer 3.2.20.09 connection problem

hello everyone. I just installed oracle SQL developer on mavericks. active JDK is 1.6.0_65. host name : som3a... now the problem is , whenever i try to make a new connection using the previous info and specifiying the default port 1433 i always get the following error
Status : Failure -Test failed: Cannot connect to Microsoft SQL Server on som3a
- can these fields ( connection name , username ,password ) take any values or do they need to be something special like ? i mean the host name must be som3a right so do the same constraint apply on these fields ?
-i tried telnet som3a 1433 , it gets stuck at "trying..."

I think you have the wrong forum, as this forum is dedicated to the Oracle Database Cloud Service.

SQL Developer 1.5 Missing DB Connection Tabs

After installing SQL Developer 1.5 EA1 in a new directory, I do not have the Sybase, MS SQL, MYSQL tabs when I try to create a new entry in the Database Connection window. Is this a Java problem? I have many database drivers and tools installed on the same workstation.

I've installed SQL Developer 1.5 EA3 (sqldeveloper-5304.zip incl JDK1.5.0_06) on Windows XP (service pack up to date).
I've downloaded http://download.sybase.com/pub/jConnect/jConnect-6_05.zip for Sybase connectivity and unzipped to "C:\Program Files\sybase\jConnect-6_0"
I add the drivers under Prefs > Database > Third party drivers as:
c:\Program Files\sybase\jConnect-6_0\classes\jconn3.jar
and/or
c:\Program Files\sybase\jConnect-6_0\classes\jTDS3.jar
When adding a connection, I only get Oracle and Access tabs (not a Sybase one too).
Moving the .jars to a path without spaces didn't help.
Please help.

SQL Developer on Windows trying to connect to M/F with RACF authentication

I am currently running the latest downloaded version of SQL Developer on a Windows XP client machine.
We have recently upgraded our z/os Oracle version to 10.2.0.3
I was advised to use the thin java client in SQL Developer by inputting the URL into the advanced window - jdbc:oracle:thin:user/******@ukmet-***:3010:***
This returns an ORA-28037 Cannot get session key for RACF authentication
If I however substitute oci for thin then I get a test successful but the subsequent attempt at a connection crashes SQL Developer.
Any ideas on how I get a stable connection greatly appreciated

The tns list might be empty due to the bug that it's only looking for lower case tns file names. This is a bug in 1.1 and has been addressed with the patch. Also in 1.1, there are some instance where the tns file is not picked up through the registry setting, you might need to set the PATH variable to address that. This too has been fixed in the patch.

Sql developer 3.1.07 coumn update issue

HI,
i have below issue.
adding spaces to column when update manually through sql developer Menu. would appreciate help.
Regards

I have no idea what you are asking.
I have no idea what it means to add "spaces to column."
I have no idea what version of anything you are doing it in.
So no help is possible at this time. If you want help you need to read the FAQ and then post sufficient information for someone that can not read your mind to help you.

SQL developer drop all my network connections

Hi all,
I have used different versions of SQL Developer and I have read many forum posts but I cannot find solution for my network problem.
I can connect to my databases without any problem, but when my session goes to snipped state (due to idle_time setting) after some time ALL my network connections are dropped (e.g. my mail client give me message that cannot connect to the server, my ftp client session is dropped, my ssh session are dropped...). It is horrible because sometime I need connect to my PC remotely and due to this problem I cannot. It is not problem of my PC, I have used 2 different PCs and all is the same. If I don't start SQL Developer, I can have ssh session open for week without any problem.
Last year I used to start keepalive extension, but is really annoying for every oracle session manualy enable keepalive.
And when I open 10 db sessions and for one session I forgot click enable keepalive then all my network connections are dropped.
Yesterday I have installed current version of SQL Developer hoping that the problem is solved but today morning I find all my network sessions dropped (e.g. I need 8 ssh sessions reconnect).
Does anybody have any idea how to solve this?
Thanks.
Marian

Hi Marian,
I am not quite sure how using SQL Developer could make all client software accessing the network lose their connections. Do you use some kind of VPN (Virtual Private Network) software? Do you always try to use SQL Developer with the non-Oracle KeepAlive plug-in?
Maybe local policy imposes some limit on the total number of simultaneous connections (active or inactive) you can have, and it gets exceeded only when you run SQL Developer. Are any other application clients used to access databases from your machine(s)?
If the real network connection is stable, typically one need only worry about database session time-outs (idle limit reached) or VPN time-outs. I suggest asking for help from someone inside your organization responsible for networks. It seems like something is forcing a VPN disconnect.

Gary

Hopefully for you, the machine is not reachable from internet !
Your giving online everything needed to log in as system ! that is quite dangerous. I guess the "Onsite team" would be pretty mad discovering that.
You should edit your previous post before too much people get to it.
Regarding your problem, I guess you can't get to the machine itself (maybe in a different network).
Can you try to ping it from your computer ?ping 51.17.130.121
This is a made-up IP, you'll have to replace with yours
