Issue of Oracle SQL Developer

Hello

The problem is that when I execute queries "heavy" through SQL Developer (v. 4.1.1.19 or back) the IDE does not meet any other action during the execution of the query (queries) (I can't cancel the task). I mean if want to connect to another diagram or choose an option from the menu of the IDE, then I have to open a second window of SQL Developer. Why is it so... Is this something I did wrong?

After further investigation, I think that the following tips will help you to avoid situations where a request seems to have been cancelled but...

1. He continues to run on the DB.

2. subsequent attempts to use or to break this connection are blocked.

3. another action (as if we were trying to close SQL Developer) causes the interface user to hang completely.

Your first choice should be to install an Oracle client (full or instant) and configure SQL Developer in Tools > Preferences > Database > advanced to use the JDBC OCI/thick driver.

If you do not want to install an Oracle client and prefer to use the JDBC Thin driver by default, then adding this to the file sqldeveloper.conf to your installation should help:

AddVMOption - .net .disableOob Doracle = true

The full dump thread you provide merely reflects the fact that the request does not actually get cancelled, the login is locked, and any other attempts to use it will hang. Anyway, as long as the user interface does not block, even if a request did not get cancelled at the DB level you should always be able to do things like...

1. open an unshared connection (Ctrl + Shift + N) of the worksheet occupied this connection.

2. create another name of the connection with the same details as the locked connection and use it.

3. open Tools > Sessions of the monitor for a user with enough power and kill the hanging session using the menu popup kill .

I hope this helps.

  • Issue of Oracle SQL Developer when you use VPN (Cisco)

    All,

    We have a somewhat obscure issue with connectivity SQL Developer to our databases of the laptop has distance from the employee.

    The database is hosted inside our firewall and when the employee is trying to connect to the database that it receives the following error message:
    + "Encountered error: an error has occurred to perform the requested operation: the network adapter could not establish the connection." Code provider 20 "+"

    I think maybe I saw the error at some point as well...
    Status: Failure-Test failed: IO error: the network adapter could not establish the connection

    Note: It gets this error when you are connected to our VPN & so that it can connect through SQL * more on that same basis. It gets the error without worrying if he uses the option to enter tnsnames in SQL Developer or if it uses the "basic" connection type

    What is interesting, is that if he disconnects the VPN, will turn off its wireless connectivity, then hard-wire in our network, it can connect, without issue.

    The strangest part for me, is that although it cannot connect to the database using SQL Developer, it can connect through SQL * more. It can ping the IP source address very well, he can tnsping database without problem, it can connect through SQL * Plus, it just cannot connect through SQL * Developer. Since SQL * more and tnsping work, I know that it can access the db server through port 1521, so I don't think it's a problem of port.

    Another weird thing: when it connects to our network via a 'old' virtual private network (VPN open) there is no problem.

    His machine is Windoz 64 bit (HP laptop) and it uses the latest version of the SQL Developer and a JAVA virtual machine.

    Also interesting: I also have a Windoz 64 bit computer laptop (Lenovo) and I don't have the same issues, as it does. I am however running an older version of SQL Developer and probably an older JVM.

    I dug around a bit, looks like maybe it has something to do with IPv6? No idea what to do next, except have my network guy look at the logs of firewall to try to grasp where the connectivity has been ignored.

    Any ideas or suggestions would be appreciated. I tried all sorts of things (giving him my file tnsnames.ora and sqlnet.ora, manually editing these files, try IP addresses instead of host names, host names I tried with the doman.org extensions, etc.).

    Still, any suggestion would be appreciated and I thank very you much.

    If it is IPv6, you can try adding

  • Oracle SQL Developer 3.0: Debugging of PL/SQL anonymous blocks: ISSUES

    Hello
    I just downloaded the Oracle SQL Developer 3.0. I used EA versions because they have emerged and was happy to see the final version. So I immediately tried to debug an anonymous block (something I was not looking to do in EA versions) and nothing happened.

    The "Debug" is grayed out and the string 'ctrl-SHIFT-F10' key did nothing. I found this forum:
    Re: 30EA1: debugging of anonymous block?
    and Vadim Tropashko follow-up advice. This has nothing to my anonymous block but has worked well for a simple example.

    So I started to whittle my anonymous block to the bottom to find the culprit, here's a breaking point repeatable for me:
    declare
        stmt1 long;
        stmt2 long;
        stmt3 long;
        stmt4 long;
        p_data varchar2( 500 );
        i      varchar2( 10 );
    BEGIN
        STMT1 := 1;
        STMT2 := 1;
        STMT3 := 1;
        STMT4 := 1;
        
        --the moment this is in the block "Debug" is no longer an option
         select
            SendDocumentResult
           into
            p_data
           from
            XMLTABLE( '/data' 
                    PASSING 
                    xmltype.createxml( '<?xml version="1.0" encoding="utf-8"?><data><SendDocumentResult>test</SendDocumentResult></data>' ) 
                    COLUMNS SendDocumentResult varchar2( 1000 ) PATH 'SendDocumentResult' ) ;
    end;
    The moment that I SELECT INTO... XMLTABLE() it fails (a normal SELECT INTO works very well).

    Is this a problem with my environment or there's a problem with SQL Developer 3.0.04. Overlooking the comments of K, it seems that debugging has worked for 'simple' blocks, so I wonder if it's just out of reach...

    My environment:
    Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production     
    PL/SQL Release 11.2.0.1.0 - Production                                           
    CORE     11.2.0.1.0     Production                                                         
    TNS for IBM/AIX RISC System/6000: Version 11.2.0.1.0 - Production                
    NLSRTL Version 11.2.0.1.0 - Production
    
    and Oracle SQL Developer
    3.0.04 (Buld Main 04.34 with bundled Java) on a Window's XP box.

    The analysis has been the problem indeed. Can offer no alternative workaround, that packing horror XML in a view.

  • Oracle SQL Developer to the database unifying connection

    Hello community!

    I am developing a SQL string that will pull data from various processes of cost (i plan to wrap the dataview object in a cube and publish a dashboard after that). I was wondering if there is any way to connect oracle SQL Developer for oracle hosted instance unify to create code more efficiently? If so, explain the steps for me please?

    I can get the following information of Oracle BI Publisher, see Exhibit A.

    I have to fill in the fields in Appendix B and this is where I don't know how to do this, see Exhibit B.

    Your help is highly appreciated

    Concerning

    Amir

    Hi Amir - there is currently no way to directly connect to the DB for unifying hosted environments. We are currently working on this issue.

    In the meantime, you can use the SQL Editor in your BI Publisher server interface. You build instructions SQL can then be pasted in via data in unifying views.

  • Taking JDBC connection configuration supported the RAC in Oracle SQL Developer?

    How can one Oracle SQL Developer be configured to successfully connect to a [Oracle RAC | http://en.wikipedia.org/wiki/Oracle_RAC] environment, that is, not only the installation program always to connect to one of the individual nodes?

    [http://programmersjournal.blogspot.com/2008/08/jdbc-connection-string-for-oracle-rac.html] is an example of a classic and taking version supported the equivalent CARS of a JDBC connection string. I've used a CAR of the same format connection string from within Java applications custom without problem. I thought that the same thing should be configurable in Oracle SQL Developer, by setting the 'Connection Type' drop-down menu on "Advanced", then enter the connection string JDBC RAC-aware as "Custom URL JDBC". However, after the test connection, the following error message is displayed at the bottom of the dialog box:

    Status: Failure-Test failed: IO exception: NL Exception has been generated

    There is no additional information shown on the display 'Page Logging'. With the help of Oracle SQL Developer 1.5.5.

    Thank you!

    You could always give the current 2.1 ai2 test... continuous development may have fixed the issues in this area...

    Hope that helps,

    (1) Note that there is a separate SQL Developer forum where you probably want to run this kind of issue in the future

    (2) assuming you are using 1.5, tools | Preferences | Database | NLS parameters has an option to Format for a Date. You want to change this to any mask format you prefer.

  • Why is-menu Oracle SQL Developer navigation so slow?

    For example if I click Tools, it takes like 5 seconds to open.

    The cursor icon taking also like 2-3 seconds to next day where it is.

    Can anyone help or point in a direction?

  • Partitions don't synchronize only not - Oracle SQL Developer 4.1.3.20

    Hello

    First of all, thanks a lot for developers for this great tool.

    I use the Data Modeler which comes with Oracle SQL Developer 4.1.3.20.

    In the 12 c database, I created the following table:

    CREATE

    TABLE MMOURA. TEST_TABLE

    (

    NUMBER OF ID_TEST_TABLE (10) NOT NULL

    DATE_TEST_TABLE DATE NOT NULL

    )

    ORGANIZATION HEAP PCTFREE 10

    LOGGING NOCOMPRESS NO INMEMORY

    NOCACHE NOPARALLEL NOROWDEPENDENCIES DISABLE THE MOVEMENT OF THE LINE;

    I import with Data Modeler and add the partition:

    CREATE

    TABLE MMOURA. TEST_TABLE

    (

    NUMBER OF ID_TEST_TABLE (10) NOT NULL

    DATE_TEST_TABLE DATE NOT NULL

    )

    ORGANIZATION HEAP PCTFREE 10 TABLESPACE SYSTEM NOT LOGGING NOCOMPRESS NO INMEMORY RANGE PARTITION

    (

    DATE_TEST_TABLE

    )

    INTERVAL OF

    (

    NUMTOYMINTERVAL (1, 'MONTH')

    )

    (

    PARTITION P_BEFORE_2010 VALUES LESS THAN (TO_DATE (JANUARY 1, 2010 ',' DD/MM/YYYY "")) NOCOMPRESS

    )

    NOCACHE NOPARALLEL NOROWDEPENDENCIES DISABLE THE MOVEMENT OF THE LINE;

    So I can create a partition and generates the correct code.

    I click on "Synchronize data dictionary with model" and see the differences with the model and the database.

    In the models 'compare', 'Physical Details' is red. 'Partition' is red, "Selected" are marked, "Source table: TEST_TABLE ' is YES and" target Table: TEST_TABLE "is no.

    "Partitioning" is marked, and I can see the new partition "P_BEFORE_2010."

    But when I click on 'Overview of DOF', theres no changes:

    Thanks for reporting the problem. I logged a bug.

    You can view together as "list of system types" directory to "preference > Data Modeler"-probably no longer exists. I guess that the setting for this directory is empty when you start SQL Dev as a different user.

    I checked in SQL Developer 4 and I found no option to do this.

    I don't think it's available. You can open the table and add filters on each column and change. Or you can add where clause as suggested the link written by Jeff that I already gave. (http://www.thatjeffsmith.com/archive/2013/06/sql-developer-im-looking-at-a-record-how-do-i-edit-it/)
