IO Error 17002 in Oracle SQL Developer

Hi,
I am trying to connect to the test database using the Oracle SQL developer but I am getting the below error
IO Error: The network adapter could not establish the connection vendor code 17002
I used to connect to the test server fine 2 weeks ago (the test server is on another network and i connect to it using the VPN).
I am able to connect the the Production Database through the Oracle SQL developer (without VPN) but when I try to connect to the test i am getting the error.
I have checked the service name and ports and everything is fine and. So what could be the problem?

I am not able to connect through sql/plus as well
However, I am able to ping the test server

    Hello,
    I get the same error after updating through Help->Check for Updates. I am at version 1.1.2.25 and the update does not change the version number of Oracle SQL Developer (Help->About), it remains at 1.1.2.25 (although if I look in extensions tab, it says: oracle.sqldeveloper 1.1.3.27.66 Loaded, possible bug in displaying version number?). These are the updates applied:
    Upgraded Extensions
    Oracle Microsoft Access Browser version 1.1.3.27.66
    Oracle SQL Developer - Snippet version 10.1.3.27.66
    Oracle SQL Developer version 1.1.3.27.66
    Oracle SQL Developer - Reports version 10.1.3.27.66
    Oracle SQL Server Browser version 1.1.3.27.66
    Oracle MySQL Browser version 1.1.3.27.66
    Oracle SQL Developer - Worksheet version 10.1.3.27.66
    Oracle SQL Developer - Extras version 1.1.3.27.66
    Oracle SQL Developer - SearchBar version 10.1.3.27.66
    Oracle SQL Developer - Object Viewer version 10.1.3.27.66
    I ran the update several times and was able to reproduce the error under a specific condition. If I am connected to a database at the time of the update I get the error. If I am not conneceted at the time of the update I do not get the error.
    As stated, by Donal, sql developer seems to get over the problem after restarting itself twice.

  • 404 error when downloading Oracle SQL Developer 2.1 (2.1.0.63.73) for Mac

    Greetings,
    I'm getting a 404 error when I try to download the Mac OS X version of Oracle SQL Developer. The download page is at
    http://www.oracle.com/technology/software/products/sql/index.html
    And it links to the Mac version at:
    http://download.oracle.com/otn/java/sqldeveloper/sqldeveloper-2.1.0.63.73-macosx.tar.gz
    Which doesn't exist.
    Is this the correct forum to report this problem?
    Thanks
    Mick

    I don't know what to say: I went to this link
    http://www.oracle.com/technology/products/database/sql_developer/index.html
    Clicked on Download in the upper right corner, re-accepted the whatever-they-wanted-me-to-accept and then the OSX download suddenly worked. Give it a spin and see if a circuit like that works for you.
    Good luck!

  • Oracle SQL Developer Data Modeler start up error

    Hi All,
    I just downloaded Oracle SQL Developer Data Modeler (2.0.0.57.0) [Released 1 July 2009] by selecting the option "Oracle SQL Developer Data Modeler for Windows (This zip file includes the JRE)"
    After I installed the same and tried to run it by clicking datamodeler.exe, I get the following error message
    "unable to create an instance of the Java virtual machine located at path:..\jdk\jre\bin\client\jvm.dll"
    On the same machine I can successfuly run the Oracle SQL Develper with no errors. My machine is having Windows XP Professional SP3.
    Any ideas? If there was a problem with Java, than the Oracle SQL Developer should also not run. But as stated it runs with out any error but the Oracle SQL Developer Data Modeler gives the above error.
    Regards,
    JAA149

    1 - The above problem has nothing to do with the memmory. I tried on a 400 MB RAM, 900 MB RAM, 1.5 MB RAM & 2 MB RAM with the same arror.
    "unable to create an instance of the Java virtual machine located at path:..\jdk\jre\bin\client\jvm.dll"
    http://i30.tinypic.com/9vkwf6.jpg
    2 - There are two "datamodeler.exe: files
    One is at D:\datamodeler\datamodeler.exe
    2nd is at D:\datamodeler\bin\datamodeler.exe
    The same error occurs with both the files.
    3 - The Oracle SQL Developer Data Modeler version is "Oracle SQL Developer Data Modeler (2.0.0.57.0) [Released 1 July 2009]" and the file I downloaded is "Oracle SQL Developer Data Modeler for Windows (This zip file includes the JRE) - (57M)"
    If I look in "D:\datamodeler\jdk\jre\README.txt" I find
    "Java(TM) Platform, Standard Edition Runtime Environment Version 6"
    If I run "D:\datamodeler\jdk\jre\bin\javacpl.exe" I get
    http://i30.tinypic.com/mt8ocn.jpg
    If I run "D:\datamodeler\jdk\jre\bin\jureg.exe" I get
    http://i28.tinypic.com/30boiyo.jpg
    If i check at the control panle add/remove program
    http://i30.tinypic.com/1428tba.jpg
    If I go to "http://www.java.com/en/download/manual.jsp" and download "jre-6u16-windows-i586-s.exe" and run it.
    If I go to "C:\Program Files\Java\jre6" I find the same files as in "D:\datamodeler\jdk\jre"
    I am able to run Oracle SQL Developer with out any kind of error let alone the above one. But with Oracle SQL Developer Data Modeler I get the above mentioned error no matter what I try.
    As the error states "unable to create an instance of the Java virtual machine located at path:..\jdk\jre\bin\client\jvm.dll". The file "jvm.dll" is located at two places. One at "D:\datamodeler\jdk\jre\bin\client\jvm.dll" and the second at "D:\datamodeler\jdk\jre\bin\server\jvm.dll"
    A similiar problem occurs with JDeveloper with the fllowing solution
    http://forums.oracle.com/forums/thread.jspa?threadID=506339&start=0&tstart=0
    Which states the following
    "hello!
    in the problem with JDeveloper i have a solution. The jdk have a file jvm.dll in the path: jdk/jre/bin/client/jvm.dll this is the problem ... now in the path:jdk/jre/bin/client/ojvm has a file with the same name if you copy and paste this file to the another path, now its works fine your Jdeveloper.
    Jdeveloper use two files to jvm.dll to work one in the folder /client and other in /server copy the same file to the two locations for precaution
    for me work fine thanks..."
    I tried to do the same (Copy from client folder to server folder)
    D:\datamodeler\jdk\jre\bin\client\jvm.dll
    COPIED THIS FILE TO
    D:\datamodeler\jdk\jre\bin\server\jvm.dll
    Nada. So I reversed it (copied from server folder to client folder)
    D:\datamodeler\jdk\jre\bin\server\jvm.dll
    COPIED THIS FILE TO
    D:\datamodeler\jdk\jre\bin\client\jvm.dll
    Does not work. So I tried another solution stated at the same forum entry
    "Well,
    i solved the problem by this way :
    <SQLDEVELOPER>/jdev/bin/ide.conf
    In this file, change this line :
    AddVMOption -Xmx512M
    by
    AddVMOption -Xmx256M
    Now, the executable is lauching correctly. No more errors with Java Virtual Machine.
    But is it a good thing to solve it like that ?"
    But the ide.conf file is only at "D:\sqldeveloper\ide\bin\ide.conf" which is for the SQL Developer and not the SQl Developer Data Modeler
    Correct me if I am wrong but
    JRE = Java Run Time Envoirment
    JDK = Java Development Kit
    And Oracle SQL Developer Data Modeler needs JRE and not JDK. In any case I download JDK
    jdk-6u14-javafx-1_2-windows-i586.exe (121,306 KB) and installed it but no succcess.
    I tried every thing except completely re-install my whole PC.
    Any help will be much appreciated.

    This typically indicates that the connection to the database was unsuccessful (incorrect values in client tnsnames.ora). Are you able to tnsping the database successfully from the client ?

  • Oracle SQL Developer  error - "The file-based source procedure Name is not present in the database."

    I recently started working on the Oracle SQL developer. I have 'select' privileges on the QA schema and when tried to execute proc in QA. It is giving the error as 'The file-based source <procedure Name>  is not present in the database.  Was it compiled?'
    instead 'you do not have sufficient privileges to execute this procedure'. Did research on internet but with no luck.What configuration changes needed to be done to make it work.Guide me.

    Sounds like you do not have the correct privileges.  What should have been granted to you by the QA user, or some other user with appropriate privileges, is...
    grant EXECUTE on "QA"."<PROCEDURE_OF_INTEREST>" to "<YOUR_USERID>" ;
    Note that a grant of execute on a procedure has nothing to do with grants of select on some or all of QA's tables and views.
    So, as Vadim suggests, from your connection node in SQL Developer's Connections view, if you expand the Other Users node, then expand QA and look in the Procedures node, do you see the procedure of interest?  If not, you cannot expect to be able to execute it from your userid's connection. And even if you do see it, you may have some other privilege that permits viewing but not executing, like...
    The role SELECT_CATALOG_ROLE
    The system privilege SELECT ANY DICTIONARY
    And even if you do not see it there, then having certain other privileges granted to you could permit executing it in general, like...
    The role EXECUTE_CATALOG_ROLE
    The system privilege EXECUTE ANY PROCEDURE
    Also, note that the 3.0 release is a bit dated nowadays. Upgrading to 4.0.3 production or even the 4.1 EA2 (early adopter) release will, in general, give you a better experience.
    Best wishes,
    Gary

  • Oracle SQL Developer and Errors (Line Number Incorrect)

    First, I wanted to state that Oracle SQL Developer 2 is a standout job.
    I wanted to report, though, that when Oracle SQL Developer 2 can't compile a block of code or a simple SQL statement has invalid syntax, it does not have an option to accurately go to the line of code in question. GOING TO the erroneous line of code doesn't need to be a feature, but often times the line no. REPORTED by Oracle SQL Developer is incorrect by 50+ lines.
    Is this something I could fix on my end? I have five other developers griping about this.
    Thank you!

    I don't know if this is the situation you are talking about, but line numbers for errors in SQL in a SQL Worksheet are not line numbers within the statement but rather line numbers in the worksheet. For example, with the following SQL in the worksheet:
    select * from dual;
    select * from dual;
    select * from dual;
    select from dual;Running the "select from dual;" statement (as either statement based on cursor position, selected statement or as script), the error is reported on Line 4, Column 7. As I show line numbers (Tools | Preferences | Code Editor | Line Gutter | Show Line Numbers), this makes sense. Without line numbers showing or having the option to go to the error and with more realistic examples with SQL statements scrolling off the page, I can see that the line number in the errors wouldn't be helpful.
    I think -K- is talking about the PL/SQL code editors not reporting the correct line number based on the error line not counting the "create or replace" line at the start of a package (and more for triggers).

  • Pl/SQL Error ORA-00904 not showing in Oracle SQL Developer

    Hi,
    I am new to Oracle and the various development tools available.
    Whilst using Oracle SQL Developer we have come across a scenario where a PL/SQL package does not compile, but only shows warnings in the compiler log.
    The same packeage when compiled using PL/SQL Navigator shows a much more detailed list of errors, and highlights the real problem.
    Why does Oracle SQL Developer not show the following error?
    PL/SQL: ORA-00904: "SERIAL_LINE_ID": invalid identifier
    Regards
    Adrian

    There are various settings you can give to messages. (eg, informational, warning, severe).
    Tools-PL/SQL compiler options.
    Normally, just the first 20 messages are displayed.
    Either change code to get rid of warning messages, or change settings to ignore informational and warning messages.
    P.S. There is a dedicated sqldeveloper forum where your question should really have been posted.

    Hello Irian and Sue,

    Used parameter files:
    D:\app\product\11.2.0\dbhome_1\network\admin\sqlnet.ora
    Used TNSNAMES adapter to resolve the alias
    Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST =localhost
    *)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = ORACLE)))*
    TNS-12537: TNS:connection closed
    Thanks for your response to my initial post.Do u have any other methods to resolve this?

  • Oracle SQL Developer freezes and locks up computer randomly

    I attempted to find a solution to this before posting. I looked through the first 40 pages of this forum and on Google, through the Developer documentation, etc. with no luck.
    The problem: while using Oracle SQL Developer, the computer randomly freezes. Things work, but it hangs too often and for too long to use. This is random - it can happen every 10 seconds or every 2 minutes. The mouse will lock up, and the keyboard buffer will get all messed up. For instance, if it happens to freeze while I'm hitting "backspace", it will delete many lines of text (I've lost a bit of work because of this in the past). The freezing will last about 2 to 20 seconds, and the only way out of it is to ctrl+alt+delete and kill SQL Developer.
    If SQL Developer is running, and I'm in a different window - it will freeze the other windows as well. Again, it's impossible to use unfortunately. My coworker doesn't have the same problem, and he's connecting to the same database with the same version using Windows Vista. It must be something on this computer. I reformatted about 1 month ago, so it's a pretty fresh install and I haven't installed much of anything yet.
    I'm using Windows Vista Enterprise 32-bit w/SP1.
    This was occurring with older versions of SQL Developer (1.2). I'm using the newest install that included the Java JDK. I've completely removed Java, my Oracle installs, and a host of other attempts to fix this, and nothing changes. I've tried running the .exe in the bin directory as administrator as well.
    Currently using Oracle Developer 1.5.1.54.40.
    Any ideas?

    I tried dumping the contents, but the java dump wasn't showing anything at all, and it would never freeze while I had the console window in focus, so it wasn't very helpful unfortunately.
    I fixed this issue by uninstalling the Java runtime on this machine and installing the Java JDK 6 Update 7 from java.sun.com/javase/downloads . I then downloaded the SQL Developer 1.5.1 version without the Java runtime included, and pointed it to the Update 7 .exe file upon first load.
    I was using JDK 6 Update 6 previously, and it must have been behind the errors. Note that the Update 7 has to be downloaded from that website as it's a new version that hasn't been posted on the regular java.com site yet.

  • Oracle SQL Developer to be used in laptop

    Hi all,
    I have downloaded oracle sql developer for my Windows 7 laptop. I am able to make SQL queries but unable to run any PL SQL block. I am unable to create any connection and gettinf an error 'IO Error: The Network Adaptor could not establish the connection.'
    I do not have oracle installed in my local system. I just want to write a few blocks and use it for my personal purpose. But for packages, procedures etc it is not allowing me use any connection.
    I want a simple application for my personal use only which will help me to learn the basics.
    Please guide me regarding that.
