AddVMOption command in SQL developer configuration files

Greetings developers,
I'm a newbie in database and Java world trying to understand what the Oracle sql developer configuration files do by executing AddVMOption commands. I'm guessing this command is something to do with Jdeveloper. Please enlighten me what the command does.
Regards,
Valerie

Valerie,
Nothing to do with JDeveloper at all.
SQL Developer (and JDeveloper incidentally) are created using Java - the AddVMOption's that you are referring to are arguments passed to the Java Virtual Machine that is used to run SQL Developer. For example, you can use AddVMOption to give more memory to SQL Developer.
Hope this clarifies,
John

  • Oracle SQL developer configuration file

    Greetings experts,
    I'm a newbie in a Java and Database world trying to understand configuration file in Oracle SQL developer. It uses command like AddVMOption. I'm guessing this is a Java language related command. Is this true? If yes, what does it do?

  • Getting an error while importing Development Configuration file (NW 2.0)

    i,
        while importing a development configuration file for Webdynpro (  SAP NW 2.0 ), i am getting an error
       "Getting Input Stream Failed-> Unable to find the host ..."
    But i can ping to the server and tr is also working .
    i could see Active and Inactive Objects
    Any access permission is needed to download a configuration file.
    or whatis the reason for this error.
    any preconditions have to be done for importing a configuration file ?

    You can try the following:
    1. try the fully qualified domain name of the DTR server host in NWDS Preferences->Development Configuration.
    2. Are your WAS and JDI are on a higher SP level. That may cause the problem

  • Setting IIS W3C Extended Log File settings via command line, registry or configuration file

    I am currently in need of a way to set IIS W3C Extended Log File settings via command line, registry or configuration file.  More specifically the 'Bytes Sent (sc-bytes)' and 'Bytes Received (cs-bytes)' settings that are not enabled by default. 
    If anyone knows where I can locate these setting (outside of the GUI) for all IIS versions that would be greatly appreciated.

    I believe I have found a valid solution. You must have the WebAdministration module loaded.  I hope this helps someone.
    Use the following syntax to view current W3C fields:
    Get-WebConfiguration -filter system.applicationhost/sites/sitedefaults/logfile | select-object -expandProperty logExtFileFlags
    Use the following syntax to set W3C fields:
    Set-WebConfigurationProperty -Filter System.Applicationhost/Sites/SiteDefaults/logfile -Name LogExtFileFlags -Value "Date,Time,ClientIP,UserName,SiteName,ComputerName,ServerIP,Method,UriStem,UriQuery,HttpStatus,Win32Status,BytesSent,BytesRecv,TimeTaken,ServerPort,UserAgent,Cookie,Referer,ProtocolVersion,Host,HttpSubStatus"}

  • Spool command in SQL Developer 3.1

    Hi,
    I am using sqldeveloper-3.1.05.97 .
    There are few scripts that I need to run on a EBS sandbox to generate txt files for a analysis tool input .
    The script is meant to be run with SQL * Plus but I am getiing a TNS listener error due to which I want to use SQL Developer.
    The Spool command is able to create file in local directory but the oputput is not the query result but the query itself. Please help if anything is wrong in the syntax below:
    ALTER SESSION SET NLS_DATE_FORMAT = 'MM/DD/YYYY';
    SET NEWPAGE 0
    SET SPACE 0
    SET PAGESIZE 0
    SET ECHO OFF
    SET FEEDBACK OFF
    SET COLSEP |
    SET MARKUP HTML OFF
    SET LINESIZE 600
    SPOOL FND_USER.txt
    SELECT USER_ID, USER_NAME, LAST_UPDATE_DATE, LAST_UPDATED_BY, CREATION_DATE, CREATED_BY, START_DATE, END_DATE, DESCRIPTION, LAST_LOGON_DATE, PASSWORD_DATE, PASSWORD_ACCESSES_LEFT, PASSWORD_LIFESPAN_ACCESSES, PASSWORD_LIFESPAN_DAYS, EMPLOYEE_ID, CUSTOMER_ID, SUPPLIER_ID
    FROM APPS.FND_USER;
    SPOOL OFF

    Hi Partha,
    It seems the line "SET PAGESIZE 0" is suppressing all output in SQL Developer, and not just "all headings, page breaks, titles, the initial blank line, and other formatting information" as documented for SQL*Plus. Keep in mind that SQL Developer does not yet provide full support for all SQL*Plus formatting commands. For example, without SET PAGESIZE 0, the script output tab shows these messages:
    line 2: SQLPLUS Command Skipped: set NEWPAGE 0
    line 3: SQLPLUS Command Skipped: set SPACE 0
    line 8: SQLPLUS Command Skipped: set MARKUP HTML OFF
    I will log a bug for this.

  • Using the equivalent of a BREAK ON command in SQL Developer SQL window

    Folks.
    In SQL*PLUS "BREAK ON Col1 ON Col2;", I can generate a report similar to the following:
    Col1Value1 Col2Value1 Col3Value1
    Col3Value2
    Col3Value3
    Col2Value2 Col3Value1
    Col3Value2
    Col3Value3
    Col1Value2 Col2Value1 Col3Value1
    Col3Value2
    Col3Value3
    Col2Value2 Col3Value1
    Col3Value2
    Col3Value3
    etc.
    I want to be able to do the same thing in my SQL Developer SQL window so that I can export the results to a spreadsheet file.
    Does anyone know if this is possible?
    I've tried using the SQL*PLUS BREAK command in my SQL Developer window but it appears to be ignored. My resultset looks something like
    Col1Value1 Col2Value1 Col3Value1
    Col1Value1 Col2Value1 Col3Value2
    Col1Value1 Col2Value1 Col3Value3
    Col1Value1 Col2Value2 Col3Value1
    Col1Value1 Col2Value2 Col3Value2
    Col1Value1 Col2Value2 Col3Value3
    Col1Value2 Col2Value1 Col3Value1
    Col1Value2 Col2Value1 Col3Value2
    Col1Value2 Col2Value1 Col3Value3
    Col1Value2 Col2Value2 Col3Value1
    Col1Value2 Col2Value2 Col3Value2
    Col1Value2 Col2Value2 Col3Value3
    .

    OK thanks.
    I did get around this by using SQL*PLUS to generate an output file with a separation character between the columns and spooling the SQL*PLUS output to a text file.
    I then open the text file with Excel and specify the same character as a column separator. Seems to load properly into Excel.

  • Does SQL Developer allow file spooling?

    Hello, I'm asking whether SQL Developer application allows me to use the spool command to save all the queries I entered during a session into a text file, just like we used to do in sqlplusw.exe, so that they can be used for reference? or do we have to save each single query we enter?

    You can also select All in the output windows. Then you can right click to export the data from the output in several format.

  • SQLPLUS commands in SQL Developer

    We are using 11g with Sql Developer. We have some script such as healthcheck etc provided by oracle support, which has SQLPLUS commands in it.
    We are not able to run those in SQL Developer. We are getting errors.
    Are there any way, we could invoke SQLPLUS shell within SQL Developer?
    Thanks in helping.

    Hi qwe16235
    SQLPLUS command failed - not enough arguments

    The other command seems like an error in the middle of a PL/SQL block which we should have covered, just the start of it is not enough to know what the error is.

  • SQL developer bat file not found?

    (possibly this should be posted in another place)
    I installed the new Oracle 11.2.0.1 64 bit in windows 2008 sp2 64 bit, the sqldeveloper doesn't work,
    D:\app\serv_hyperion\product\11.2.0\dbhome_1\SQLDEVELOPER\SQLDEVELOPER\BIN\sqldeveloper.bat
    Actually, I cannot find this bat file, this is strange. And I have to refer to the sqldeveloper.exe file, and it looks for a java, and I refer it to a jdk or jre Java, but stilll error happens. what happens? why i cannot find the sqldeveloper.bat file?
    when I refer the sqldeveloper.exe to JRE java.exe, the error is: J2SE SDK is not found. If I refer the sqldeveloper to JDK java.exe, the error is Java Virtual Machine is not available. I have 2 issues: the first probelem is I cannot find the sqldeveloper.bat that should exist, the 2nd problem is I cannot start the sqldeveloper.exe no matter if I use JRE or JDK, thanks!

    Hello,
    Sincerely, I always install SQL Developer separately on a directory whose name specify the Release. For instance, sqldeveloper-2.1.1.64.45.
    Because Oracle delivers new release every 2 or 3 months, and it's recommended to do not modifying Oracle Server installation without using OUI.
    Then, you can locate the sqldeveloper.exe on this directory and create a shortcut to it.
    Afterwards, when you want to install a later release (sqldeveloper x.y.z.aa.bb) you may create another directory for that and import straigthly all the connexions you already defined from the former installation.
    By exporting / importing connexions you won't have to recreate them.
    By that way, you may have several releases of sqldeveloper and compare them. Sometimes there're differences between them.
    For instance, the first release of SQL Developer (1.1) allows connexions to Oracle 8i database while it's not allowed in 2.1.
    Hope this help.
    Best regards,
    Jean-Valentin

  • SQL Developer export files not visible

    Hi All,
    I've started using SQL Developer recently and I am completely new to this tool.
    I've noticed a weird problem. All the export files and the folders I create from SQL Developer is not visible from the normal windows. Say I've executed a query and I need to export the output to a file. I right-click on the data grid; select Export Data -> xls/csv (anything) . I get a pop to mention the Location of the file. I click on Browse ; then select the location and then click on apply. I expect the file to be created. But when I go to that folder; I do not find any files.
    To add on to my suprise; If i click on open a file and navigate to the above mentioned path; the pop-up shows that the file is present in that folder. But it is not visible from Windows. This is of no use as I cannot use those files.
    BTW; version is 2.1.1.64
    Note: I've also enabled the option of viewing all hidden files and folders in Windows.
    Regards,
    Arun

    Hi Arun,
    If you are using Windows Vista, Windows 7, or higher, and writing to a directory (like C:\, C:\Windows\, C:\Program Files\) that Microsoft wishes to protect from malware or just simple clutter , then you are running afoul of a redirect feature in the OS that puts the unwanted file in a VirtualStore folder for your user name, specifically:
    C:\Users\<yourusername>\AppData\Local\VirtualStore\<full path where you think the file got stored>See the following for details:
    http://answers.microsoft.com/en-us/windows/forum/windows_7-files/folder-redirect-in-windows-7/95218744-37e6-40cd-b890-2e647351df16
    I just ran across this myself for the case of C:\ and perhaps this applies to your situation also.

  • SQL Developer zip file

    Hi
    I am having trouble getting an unbroken copy of the latest distribution of SQL Developer. Is this a problem at my end or have others experienced the same problem.
    Cheers
    Ben

    From time to time, Oracle's servers behave kinda badly. You're not the first one experiencing that, and for sure will not be the last one either.
    Just keep trying until you get it right ;-)
    Good luck,

  • Setting sql developer CONF file

    I try to play around with its CONF file, and I have a difficulty understanding the language that is using. What language is this? I can only guess "sqldeveloper-debug.conf" is executed when I set "IncludeConfFile sqldeveloper-debug.conf" in sqldeveloper.conf. But I don't really know what those configuration files do. Could you give me some guidelines to learn this?
    Best regards,
    Valerie

    I got it, the configuration files pass arguments to Java Virtual machine......

  • SQL Developer running slow, possibly caused by Java Virtual Machine

    Dear all
    I am currently working with SQL Developer 1.5.1, connecting to an Oracle database 10.2.0.2 and it is taking about 10 minutes for SQL Developer to load. I believe the problem may be due to the Java Development kit. I upgraded to the latest version last week.
    The versions running according to Java settings is:
    1.6 1.6.0_15 http://java.sun.com/products/autodl/j2se C:\Program Files\Java\jre6\bin\javaw.exe  true

    1.4 1.4.2 http://java.sun.com/products/autodl/j2se C:\Program Files\Java\j2re1.4.2\bin\javaw.exe  trueHaving looked at other posts on here I have run SQL Developer with the console and the messages in that are as follows:

    /sqldeveloper/ide/lib/ide-boot.jar, by sun.misc.Launcher$AppClassLoader@9627532]I also use a photo Web Site, which is unrelated to my Oracle work but for it's photo uploader also uses Java, and that is running slow, which is why I think the problem is Java based. I would say the problem occurred within the last couple of months but has got much worse in recently weeks. SQL Developer is also slow at times, mainly when I've used another application and it is just in the background.
    Kind regards

    Hi there
    Thank you for taking the time to reply. I use GeoRaptor and for what I use it for, I have not come across any errors whilst using it.
    I had no reference to the JDK in my SQL Developer configuration file. I did a search on my system and could not located a copy of JDK, or one in my programs installed control panel, so I installed it again. However I then found a copy in the sqldeveloper folder. However that wasn't referenced in my control panel.
    However having added a reference to the JDK in my SQL Developer configuration file, pointing to C:\Program Files\Java\jdk1.6.0_16, it seems to be taken even longer to load.
    SQL Developer is using 98,608k once loaded and my system has 1.25GB of memory. Whilst loading I was using 1.38GB. For about a year I've had slightly less memory than I sometimes use. The reason for not having 2GB is due to a previous memory failure. However this did not cause a problem for SQL developer until more recently.
    Would it be worth reinstalling GeoRapter?
    Kind regards
    Tim
