Sql developer freezes

After a sql statement is entered it cannot be changed. I cannot add or delete anything from the statement. Has anyone every encountered this problem?
Thanks
Pany

Hi,
I finally found where all the prefernces are stored; check in C:\Documents and Settings\"username"\Local Settings\SQL Developer
Remove/backup this folder. Then restart desktop and should work. If you want to save your connections you will need to export them first and then reimport.
Hope this helps,
Adrian

  • Re: SQL-Developer Freezes Every Time I Click on a Trigger to Edit it

    Yes: SQL-Developer Freezes Every Time I Click on a Trigger just to edit it, even though the trigger is disabled. How do I get SQL-Developer to stop freezing-up and making me re-boot every time I even just click on a Trigger to select it, so that I can then rt.-click and edit it. Sometimes, SQL-Developer won't freeze immediately upon selecting the Trigger with my mouse, it will allow me to rt.-click to bring up the pop-up menu where I then try to click on "Edit" so I can change the same trigger, & as soon as I choose "Edit" SQL-Developer freezes-up -- must reboot.
    Also, one time I dropped a Trigger altogether in SQL-Developer, not just disabled it, but SQL-Developer was still launching the supposedly "dropped" trigger (the trigger also no longer appeared as an item under "Triggers" tree view) when I ran
    a SQL Script that did INSERTs: this supposedly dropped Trigger that no longer appeared anywhere in SQL-Developer was still executing (I could tell because I was getting ERROR MESSAGES in the Messages box) and the Trigger that I had executed the DROP command on from within SQL-Programmer really was only dropped and stopped executing after I re-booted. Can you help me?
    My immediate problem is the one above though. Do I need to create a Schema-Level Trigger to disable or drop all Triggers when I first logon (triggered by my logon system event), and then they will "CREATE" properly and stop freezing up and acting weird?

    Sorry, the above thread should have been a "new" post, not a reply post.

  • 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.

  • SDO_GEOMETRY displaying in Oracle SQL Developer (freezing)

    Hi,
    I am using Oracle SQL Developer (V 1.5.3) heavily at work, and have noticed some undesirable behaviour when the table's data tab is trying to display SDO_GEOMETRY. In this version (and subsequent ones) Developer tries to convert the geometry to WKT, instead of just displaying "sdo_geometry". I can see why this has been added in, however I am using many geometries that are quite large, and have extremely large sdo_ordinate_array/s . This is causing Developer to appear to be freezing while it runs the conversion, often hanging for many minutes at a time. I have briefly looked at V 2.1, and it appears to be the same.
    Does anyone know if there is a check box option, or similar to switch this behaviour off? Limiting the number of rows returned has been suggested, but even when dealing with a STATES table the 9 rows needed for all 9 Australian states is far too large for a data tab display. If an option doesn't currently exist, it might be worth adding in to future versions of SQL developer.
    regards, Jeff

    Hello,
    I´ve the same problem. I use version 3.0.03 (3.45) but I can´t find the possibility to change this option.
    Can someone help me?
    Thanks

  • EA2/EA1 - SQL Developer freeze in file editor

    I had a PL/SQL local file open (.pkb) with a database connection selected and compiled the file. There was a compilation error and when I went to correct it, SQL Developer froze (before my typing had updated the file).
    I had the console open and it shows the following exception, which I assume is relate to the freeze:

    I have just gotten basically the same exception on the console with EA2 using JDK 1.6.0_04. This time I had an SQL file open and had just looked at the history and switched back to the SQL tab to run a query.
    Is the history tab trying to do something that is not yet being shipped with EA2?

  • SQL developer freeze behaviour

    I thought SQL Developer can run multiple SQLs at the same time, or at least enable one to browse a database whilst a piece of SQL is running.
    However, I always have problems doing more than one thing at a time.
    For example, I had a piece of PL/SQL running today and then tried to start a new connection.
    All I got was an hourglass.
    I am using Version 1.5.3 Build MAIN-5783 on Windows XP SP2.
    Is it SQL Developer or Java that is causing problems like this ?
    I am not using the latest version of Java, as that is incompatible with some other products I use.
    I am however using Java Version 1.5.0 (build 1.5.0_12-b04).
    Thanks.

    SQL Developer by default only opens a single DB connection for all of the worksheets for a SQL Developer connection and a single DB connection can only do one thing at once. However, as Sue said, you can open a new worksheet and DB connection for an already connected SQL Developer connection with the Ctrl+Shift+N keystroke (called an unshared worksheet) - this will give you a second DB connection for running something else at the same time.
    I don't use this much, but I have sometimes had SQL Developer it couldn't open the unshared worksheet as the connection was busy, so it can help if you know something is going to take a long time before you run it, to create the unshared worksheet first and run the long running statement/script in it.

  • EA3: SQL Developer freezes on index creation

    OS Name     Microsoft Windows XP Professional

    Click the Index option in search dialog.
    Click the Add Index (green plus).
    Highlight the Index Name and paste (CTRL-V) a new name into the field.
    Notes: On tables with a small number of indexes (0-2) it seems to pause for a time (30+ seconds) and then return. On tables with larger numbers of indices, it just hangs and does not come back (waited 20 minutes).
    Another odd behavior in the same dialog is if you change the index name after picking your column to index, it changes the column to index back to the default value and you have to select it again.

    I forwarded this on to a developer. I see the same thing that it takes longer than it should.

  • SQL Developer 1.5.4: "Keep alive" setting to keep connections open?

    Is there any way to configure SQL Developer 1.5.4 such that it "pings" the server every now then to keep the connection open?
    It's very frustrating to be working on a script, step away from it for a while, and have SQL Developer freeze when trying to execute the next SQL statement.
    What can I do?
    My workaround--execute a "dummy" SQL statement like "select * from dual;" every now and then to keep a connection open.
    Thanks.
    Dana

    I have had this problem till I had a RAM upgrade.
    Since I have had the upgrade JDeveloper also responds well.
    A way to check is via task manager, if PF usage is more than you physical RAM size it is a indicator that you need more RAM or shut down some application that is hogging memory.
    Just to rule out if its not some other problem, have you tried working in SQL Developer running by itself or with one other program.

  • Problems using SQL*Loader with Oracle SQL Developer

    I have been using TOAD and able to import large (milllions of rows of data) in various file formats into a table in an Oracle database. My company recently decided not to renew any more TOAD licenses and go with Oracle SQL Developer. The Oracle database is on a corporate server and I access the database via Oracle client locally on my machine. Oracle SQL Developer and TOAD are local on my desktop and connected through TNSnames using the Windows XP platform. I have no issues with using SQL*Loader via the import wizard in TOAD to import the data in these large files into an Oracle table and producing a log file. Loading the same files via SQL*Loader in SQL Developer, freezes up my machine and I cannot get it to produce a log file. Please help!

    I am using SQL Developer version 3.0.04. Yes, I have tried it with a smaller file with no success. What is odd is that the log file is not even created. What is created is a .bat file a control file and a .sh file but no log file. The steps that I take:
    1.Right click on the table I want to import to or go to actions
    2. Import Data
    3. Find file to import
    4. Data Preview - All fields entered according to file
    5. Import Method - SQL Loader utility
    6. Column Definitions - Mapped
    7. Options - Directory of files set
    8. Finish
    With the above steps I was not able to import 255 rows of data. No log file was produced so I don't know why it is failing.
    thanks.

  • SQL Developer EA4 - compile/open spec/body take longer then 3.2.2

    The Compile takes too long in compare to SQL Developer 3.2.2
             Sometimes the SQL Developer  freeze
             Sometimes a warning of low memory window come up  and then goes away
    The Opening of Spec/body takes too long compare to SQL Developer 3.2.2.
    Note:
    More visible on big packages (3000,5000,10000 lines)
    Environment:
    Oracle Database 12c Enterprise Edition Release 12.1.0.1.0 - 64bit
    Windows 7 Ultimate
    Processor Intel(R) Core(TM)i7 CPU [email protected] GHz
    RAM 8. GB
    OS 64 bit

    The package body has  around 6200 lines take a while to open.

  • SQL Developer 4.0 Early Adopter 2 - avoid "Please amend your code to something like this" message

    When I edit PL/SQL packages or sql queries in SQL Developer 4.0 Early Adopter 2,
    when i copy/paste SQL code, sometimes "Please amend your code to something like this: "select * from when", or "begin when; end;" appears.
    Sometimes SQL Developer freezes.
    Can I avoid that message (turn off some kind of checks in SQL Developer properties)?

    This has been raised/documented fixed in future releases here:
    EA42 - Ambiguous Context Pop-up

  • 30EA1: 2nd instance of the sql developer delivers no query results

    Hi,
    the first instance works like expected, the 2nd one doesn't delivers any result in queries and in the Messages i found that Error:
    SEVERE     43     0          Error while registering Oracle JDBC Diagnosability MBean.
    best regards
    Werner

    hi,
    well - the main reasons have been already discussed; another intresting one
    (i don't know if somebody else was already running into it): sometimes i start e.g. a long running pl-sql block in the window
    Then i go back to e.g. the code editor to take a look on another part of the code which i want to edit - then the sql developer freezes
    (i think because something is executed through the main connection - and unfortunatly the main session is already executing something)
    When the pl-sql block is finished i can use the sql developer instance again; but in the meantime i need another instance
    in my regular work i use 3-4 instances of the sql developer
    (like mentioned above - to prevent myself by modifying the productive db during i am working on the
    development one in the same schemas, to work on another topic which a customer asked me without loosing my old work or because a window freezed)
    Here an idea (i know - maybe it is dirty) - the sql developer could open always 2 connections - one for the communication of the tool to the database (which can't be used by a window)
    and one for the window (sure - i am aware that i can open an unshared connection window, but sometimes i just forget to do that)
    Another benefit of that: currently a lot of statements are sent through the connection - if i want to trace something i have to do it in the sqlplus because these statements are messing up my trace
    however - i took a look into the new version and i am quite impressed, a lot of new cool features

  • SQL Developer 1.5.1, JDK 5 u16 + JDK 6 u7 + u10, & Insider 2.5 = FREEZE

    Just found an issue with Insider 2.5 in SQL Developer 1.5.1 while using JDK 5 u16, JDK 6 u7 or u10 on WinXP SP3:
    Insider freezes SQL Developer 1.5.1 completely.
    Console output is as follows:

    I already knew that one... There are no spaces in the connection name.
    I have also removed and reinstalled the Insider plugin with "Check for Updates". Version is 2.5.

  • SQL Developer Worksheet freezes

    Hi All,
    I'm using SQL Developer 3.1.07.42
    I'm having issues where when im in the worksheet, it will freeze for up to 20 seconds.
    This usually happens when im trying to change code, or even just clicking to a pre-existing line.
    Is there anything i can do to stop this?
    Cheers,
    Russ H.
