Is there any known problem using Oracle SQL Developer 3.0.04 with Java 1.7?

I'm new to Oracle. I have installed Oracle SQL Developer 3.0.04 and Java 1.7. When I run Oracle SQL Developer, I will get the window Running this product is supported with minimum Java version of 1.6.0_04 and a maximum version less than 1.7. This product will not be supported....
Is there any known problem using Oracle SQL Developer 3.0.04 with Java 1.7?
I have already downloaded Java 1.6 but don't know whether I need to uninstall Java 1.7 first. If don't need to uninstall Java 1.7, how can I set Oracle SQL Developer to run with Java 1.6?
Thanks for any help.

One prior post discussing the use of Java 7 is:
SQL Developer 3.0  and Java SE 7?
There is no need to uninstall any Java version (except if you have disk space constraints) and no problem switching between Java versions. This may be controlled in the sqldeveloper.conf file in your ...\sqldeveloper\sqldeveloper\bin directory via the SetJavaHome line. For example:
#SetJavaHome ../../jdk
SetJavaHome C:/Program Files/Java/jdk1.6.0_26
#SetJavaHome C:/Program Files/Java/jdk1.7.0Regards,

  • Problems using Oracle Sql Developer

    I am tryng to use the developer but I have serious problems using it. Lags, freeze, blocked screens, fatal errors without messages that make me close the application.
    It is running on Windows 2000.
    Somebody have this problems too?
    Is this tool operative or is in beta state?
    Thanks a lot.
    Miguel De Belliz.

    I executed a query & need to cancel the operation. However the busy cursor won't let me click Cancel (X) icon. Why ?
    Also from time to time a simple operation of copy / paste freezes the screen and eventually comes back to life after 4/5 minutes. Why ?
    Platform : Windows
    Version : WinXP2002SP2
    SQL Dev Version :

    We've actually found that the Server 10.6.3 DVD does an amazingly smooth job of upgrading 10.5.8. We've been upgrading our production servers and nothing has gone wrong yet. Snow Leopard employs an archive and install method of upgrading which results in an install which is very close to a clean install. So it's been very convenient for us because our servers are used as Windows PDCs and it's a pain in the *** to have to re-join all PCs to the domain if we start from scratch.

  • Unable to connect to Oracle Database using Oracle Sql developer

    Hi Everyone,
    I am searching for some help regarding my problem with Oracle connectivity. I have installed Oracle 11g release 2 on my Windows XP Professional Laptop. For a few days after installation i could connect to the Oracle database with the SYSTEM account using Oracle SQL developer ( installed on the same Laptop) but now i am unable to do so.It gives me this annoying message:
    An error was encountered performing the required operation  Got a minus one from read call .Vendor code 0
    However i am able to connect using Sql Plus by supplying the username SYSTEM and the corresponding password.
    My TNSNAMES .ora file is as follows:
    ORACLE =
    (ADDRESS = (PROTOCOL = TCP)(HOST =localhost)(PORT = 1521))
    (SID = CLRExtProc)
    My Listener.ora file is as follows:
    (SID_LIST =
    (SID_DESC =
    (SID_NAME = CLRExtProc)
    (ORACLE_HOME = D:\app\product\11.2.0\dbhome_1)
    (PROGRAM = extproc)

    (SID_DESC =

    (ORACLE_HOME = D:\app\product\11.2.0\dbhome_1)
    (SID_NAME = Oracle)
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    My Sqlnet.ora file is as follows:
    I am new to Oracle and so i need someone in this forum who can help me resolve this problem. Also i even tried connecting to the database using Toad It give me the following error:
    ORA 12537 : TNS Connection closed
    Thanks for your patience and help in advance.

    Hello Irian and Sue,
    I can connect to the Oracle database using SQL Plus. Now when i TNSPING ORACLE from command line i get the following message :
    Used parameter files:
    Used TNSNAMES adapter to resolve the alias
    Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST =localhost

    Thanks for your response to my initial post.Do u have any other methods to resolve this?

  • Optimizing an SQL Query using Oracle SQL Developer

    Hi ,
    Currently i am using Oracle SQL Developer as my Database IDE .
    Is it possible to use Orqcles SQLDeveloper for the purpose of Optimizing an SQL Query ??
    For example assume i am having a query as :
    Select from Tranac_Master where CUST_STATAUS='Y' and JCC_REPORT='N'*
    Could anybody please tell me how can i use Oracle SQL Developer to optimize this query or any other SQL queries ??
    Please share your ideas , thanks in advance .

    1. Your query looks very simplistic as it is, so I fail to see how you can better optimise it (unless 'Tranac_Master' is a view, in which case I'd need to see the view details).
    2. No tool can automagically optimise your SQL to any degree of practical use. Very minor adjustments may be possible automatically, but really it is a question of you knowing your data & database design accurately, and then you applying your expert knowledge to tune it.

  • Getting the schema using Oracle SQL Developer 1.5.1

    I need to generate a report in CSV/XLS format using Oracle SQL Developer 1.5.1 to get the schema details
    in the below format.
    Table Name: XXXXXXXXX
    Table Space Name: XXXXXXXXXXXXXXX
    Structure :
    Field Name Data Type Size
    Xxxxxxxx xxxxxx xxxxx
    Xxxxxxxx xxxxxx xxxxx
    Xxxxxxxx xxxxxx xxxxx
    Xxxxxxxx xxxxxx xxxxx
    Field level constraint:
    Table Level Constraint:
    Index Name Column Name(s) Table space name
    Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
    Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
    Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
    Sequence Number:
    I am using a query to do that, but I cannot run more than one queries in the Create Report Dialog.
    I went to the Menu->View->Reports. In that, I chose User Defined Reports, created a new folder called Schema Detail and in that a report named Schema Detail. I right click on that report, choose Edit option, Create Report Dialog opens.
    In the Create Report Dialog, I chose the option Script for Value of Style.
    In the SQL column I enter a query "select * from table_names". But, if I enter another query after that, it does not run and reports an error "SQL Error: ORA-00933: SQL command not properly ended
    00933. 00000 - SQL command not properly ended" Cause:    Action: "
    I end the first query with a semi colon, but it does not work.
    The queries run fine in a SQL Worksheet. There, I can terminate the first query with a semi colon and enter the second query. Then, I run both of them together so that result-set of second query appears after the second.
    Am I doing something wrong? Can someone please advise on how to get the information I need?
    Thanks a lot.

    You can do it in SQL Worksheet because you are running a script. You could run the script in SQL*Plus, and even start it from a bat/cmd file.
    Or if you want this as a User Defined Report, you might make it a PL/SQL style report. Here, all output is done through DBMS_OUTPUT.PUT or DBMS_OUTPUT.PUT_LINE. You can output HTML tags or plain text. I have an example in my paper for ODTUG Kaleidoscope 2009.

  • 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:

  • Can I use Oracle SQL Developer to "Move" data?

    I'm new to Oracle and I'm trying to use Oracle SQL Developer to export data from one table (on server A) to another table (on sever B). I'm able to create a .ldr file but I don't know how to use the .ldr file in Oracle SQL Developer? I would appreciate any help you can provide.

    The name of tables are different ?
    If I understood then try this below:
    C:\> exp user/[email protected] file=maytable.dmp tables=SAFETYADMIN_TBL_0022_43
    C:\> imp user/[email protected] file=mytable.dmp full=y
    After this import, then you can:
    C:\>sqlplus user/[email protected]
    SQL> insert into SAFETYUSER_TBL_0022_44
         select * from SAFETYADMIN_TBL_0022_43;
    SQL> drop table SAFETYADMIN_TBL_0022_43;Feedback if this is not that you want.

  • How to insert data from *.dmp file to  oracle 11g using Oracle SQL Develope

    i backup my database using PL/SQL developer and made *.dmp file
    how to insert data from *.dmp file to oracle 11g using Oracle SQL Developer
    and how to make *.dmp file from sql*plus ?
    thanks in advance

    Pl/Sql developer has a config window, there you choose the exec to do the import/export.
    Find it and his home version, it may be exp or expdp, the home version is the version of the client where the exp executable is.
    Then use the same version of imp or impdp to execute the import, you do not need to use Oracle SQL Developer If you want to use it, you must have the same version in the oracle home that exp/imp of sql developer use.

  • How to use Oracle SQL Developer 4.0 to connect to Ms Access file with .accdb extension

    Hi all,

    Thank you very much in advance

    That MS Access driver is 64-bit, I think.  If SQL Developer, or JDK is 32-bit you need to use the 32-bit driver.   You can see if you have a 32-bit driver installed using  c:\windows\system32\odbcadm32.exe

  • Issue during migrating from Sybase to Oracle using Oracle SQL Developer

    I am using SQL Developer v to migrate from Sybase to Oracle Pl/SQL 12c
    While migrating the stored procedure the following block did not convert. I got NULL instead of object_id:
    Sybase Block:
    IF OBJECT_ID(‘dbo.CheckEst’) IS NOT NULL
    DROP PROCEDURE dbo.CheckEst
    IF OBJECT_ID(‘dbo.CheckEst’) IS NOT NULL
    PRINT ‘<<>>’
    PRINT ‘<<>>’
    Oracle Block after conversion:
    END IF;
    END IF;
    Lines 1 & 4 got converted to NULL. I have many places where such code is written.
    Is there any quick way to overcome such an issue? or what needs to be done in such case?

      You are using an older version of SQL*Developer.  Could you download the latest 4.0.2 version available from here -
    Oracle SQL Developer
    and check if you still have the problem ?

  • SQL Server table capture using Oracle SQL Developer

    I need to know how to set up the Oracle SQL Developer to captuer SQL Server table with correct field precision. For some reason, all NVARCHAR field precision sizes are the double of the original precision size after capturing the table.
    SQL Server table 'A' with the following field:
    name NVARCHAR( 50)
    after table capture becomes:
    name NVARCHAR2(100)
    which is double of the original precision.
    Any feed back or input is greatly appreciated.
    Thank you.
