• Extension of SQL Developer Java does not

  Hello

  I developed a small extension of Java to start the SQL Developer via command line and put some parameters such as the server name, user and password to create a connection when you start.

  THS connection will be deleted when closing.

  This extension was working fine until the 3.0.2 version and does not work with version 4.0.2.

  My question: are there changes in the load of an extension?

  Any help would be appreciated, thanks.

  My question: are there changes in the load of an extension?

  Yes - there are MAJOR changes and they include the use of "lazy" loading of extensions.

  See note on the main page of Oracle extension exchange.

  http://www.Oracle.com/technetwork/developer-tools/SQL-Developer/Extensions-083825.html Special Note regarding Extensions developed prior to SQL

  Developer v4.0:

  With the new version of SQL Developer 4.0, an extension that was written for an earlier version of the SQL Developer will no longer work. Developer SQL is based on the JDeveloper Framework. We have updated the framework to be up-to-date with the JDeveloper 12 c version. With JDeveloper 11 g 2, they switched to an OSGI framework. The JDeveloper team issued instructions to update your extensions to be compatible with the new framework and SQL v4.0 developer.

  Note that first sentence than the previous expansions 'won't work' If you use them in 4.x

  It also appears to be bugs or incompatibilities between the extension of JDeveloper published SDK and the "new" version Sql Dev 4.x uses. The public is 12.1.2, and is one that is available for download for use in the development of an extension. SQL Dev uses version 12.1.3 and who has NOT yet been published.

  I have a new thread posted recently to ask about any aspect of this compatibility, but have not yet had all the answers:

  https://community.Oracle.com/thread/3570408

  A few simple extensions, perhaps yours, may only need a small change in the file "extension.xml" use appropriate brackets.

  Other extensions will require additional changes. One of the main changes is the new ESDK of "lazy" loading of extensions use.

  Some additional info is available on the Java.net site:

• SQL Developer to crash at startup.

  I made several attempts using different versions of SQL Developer and different versions of Java on the machine with Microsoft Windows 8.1 Build Enterprise (x 64) 9600.

  sqldeveloper - 4.0.1.14.48 - no - jre.zip 235,385,812

  sqldeveloper - 4.1.2.20.64 - no - jre.zip 329,066,864

  sqldeveloper - 4.1.2.20.64 - x 64.zip 399,957,535

  sqldeveloper64 - 3.0.04.34 - no - jre.zip 154,645,086

  sqldeveloper64 - 3.2.20.09.87 - no - jre.zip 182,052,469

  sqldeveloper - 4.1.3.20.78 - no - jre.zip 331,401,110

  Example of process:

  (1) files extracted to sqldeveloper - 4.1.2.20.64 - no - jre.zip

  (2) run sqldeveloper

  (3) window appears asking you to JDK home - click 'Browse '.

  (4) access to the Java/jdk1.8.0_65 - click on "select a folder.

  (5) confirm the path with "OK".

  (6) beginning of the program - the start screen flashes on the screen, but for a short period of time (tenths of a second).

  (7) nothing else is happening.

  (8) for execution sqldeveloper again not questions about the JDK. All splash screen (once again just flash).

  (9) in the Manager of tasks (details) I see for about a half second the process 'sqldeveloper64W.exe '.

  I've tried combinations of different JDK and version of the SQL Developer - some versions display warning on the supported Java versions.

  The latest version I managed to run (ignoring warning) 3.2.20.09 has been building hand - 09.87 using java jdk1.8.0_65.

  No luck with all versions 4 +.

  I also tried to collect debugging information as described in http://www.thatjeffsmith.com/archive/2012/06/how-to-collect-debug-info-for-oracle-sql-developer/

  First attempt was unsuccessful - screen displayed for the second half and then again in line with command prompt is displayed in the CMD window.

  I tried several times and finally was fast enough to press ctr + pause/break in this short time.

  I tried it with versions 4.1.2.20.64 and 4.1.3.20.78. The latest is here:

  Please let me know if all the config files or additional information would help

  Concerning

  Location of these files can cause problems? It does not prevent SQL Developer 3.2 work.

  Apparently. Director of the company may shed some light on why this is true. In practice, you can try to force the SQL Developer user settings in a local folder that is writable, discutΘ in: problem starting sql developer 4.1.1.19.59

  For convenience, here's an excerpt.  Use your 4.1.3.20.78x64 installation.  Choose a path to a local folder, even one on a flash drive.  Should work.

  Add something like this line to the file sqldeveloper.conf to your installation:

  AddVMOption - Dide.user.dir =

• Non-Oracle DB with SQL Developer

  I wonder if any body knows if the SQL Developer "Requester" can work with databases non-Oracle? (using connection drivers we can connect to a database)

  I have to work with Teradata now, but the Oracle tool was perfect for me, now I want to use this tool to make complex queries.

  Any advise?

  I remember well, version 3.0, SQL Developer under license from a third-party tool (see ActiveQueryBuilder.jar) to replace the old Query Builder.  This tool offers support for several flavors of SQL on several RDBMS platforms.  The problem was, our team began to hear about problems with the query designer on the Oracle RDBMS as well as issues with more complex Oracle SQL queries which does not correctly handle the third-party tool.

  For various reasons, including limited control on bug fixing by the third party and emphasizing the support of third-party RDBMS Oracle migration, it was decided to take the position Query Builder provided as a tool for Oracle SQL non-expert programmers.

  I do not exactly remember when support for Oracle NON-SQL got off, but you can start with the 3.2.2 version to see if that allows him to always...

  SQL Developer downloads version 3.2.2

  .. .and chain backwards (see the link at the bottom of the page) to a previous version if necessary.

  Hope this helps,

• SQL Developer debugger does not start

  I found a strange behaviour, while debugging PL/SQL stored procedures using SQL Developer version 4.1.0.19 on Ubunto 12.04 LTS. The debugger works fine for all the bases of my company, except one. When I start a debugging session in this database, the debbuger let go forever and never debug dialog box open. When I use another IDE, for example, PL/SQL Developer of AllroundAutomations on Windows 7, the debugger works very well. I used the same user database with all necessary Preobrajensky. First I thought it was a bad configuration of the database, but as I could start with another IDE debugging sessions, I think that this is not the case. So, I would like to know if someone could help me understand what is happening.

  

  We opened a request for support at Oracle and they offer us to turn on an earlier version of the debugger to work around the problem:

  Add at the end of the file line-by-line ide.properties:

  DatabaseDebuggerDisableJDWP=true

  


  The ide.properties file can be found here (on Windows XP):

  C:\Documents and Settings\\Application Data\SQL Developer\system${VERSION} \o.sqldeveloper${SYSTEM_VERSION}

  


  or here (on Windows 7):

  C:\Users\\AppData\Roaming\SQL Developer\system${VERSION} \o.sqldeveloper.${SYSTEM_VERSION}

  for Linux users:

  $HOME/.sqldeveloper/system${VERSION}/o.sqldeveloper.${SYSTEM_VERSION}/ide.properties


  It works!

• Choose one in SQL Developer fails - SQL * more work

  Hi all

  I have the HS to MySLQ connection works correctly and most of the requirements I have in regards to the data works.

  
  However, I "only able to test my procedures and functions in SQL * more." IN SQL Developer 4.0.0.12 there is always a problem and questioning of the results are never displayed.

  Thanks in advance for any advice.

  Hello Mike,.

  I use Oracle XE 11.2.0.2 x 64 on Linux. Using the MySQL ODBC 5.3.4 connection.

  I've just upgraded the SQL Developer to version 4.0.3 (released September 2014) and the problem seems to be resolved because I'm able to query the MySQL database and get the results.

  However, there is something I don't like all the whitespace added, whether in SQL Developer 4.0.3 in SQL * more.

  Here's the query I tested:

• How to get these settings in sql developer

  According to this link, when I chose my lines in sql developer I don't get all the options illustrated in the screenshot of the binding,
  
  My sql developer is Version 3.2.20.09 64-bit windows, to use this options I need to make all the settings?

• 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

  AddVMOption -Djava.net.preferIPv4Stack=true

• New installation of SQL Developer 4.0.3 is not Java 1.7

  Just got a new computer and the Java is 1.7.0_85 so I will try to install the 4.0.3.16.84 SQL Developer because it says it's compatible with Java 1.7 version.  So I run the sqldeveloper/sqldeveloper.exe, and he invites me to the path of Java.  I enter the path to Java.exe (C:\Program Files\Java\jre7\bin) it fails with the error: could not find an If Java SDK installed to the path: C:\Program Files\Java\jre7\bin\.

  What Miss me?

  The message says that you need a software Java SE development kit.  It's C:\Program Files\Java\jdk1.7.0_85 in your case,.  If it (or some other recent jdk 1.7.0_xx) is not already there, you better download the 4.1.2 latest version.

  If your machine and the OS is 64-bit, you can download the zip file with JDK 8 (abbreviated to 1.8) already included instead of separately download the JDK and SQL Developer.  Otherwise, if yours is a 32 bit (probably unlikely at that time) OS, download a 32-bit jdk1.8

  "Status: failure Test failed: [Microsoft] [ODBC Driver Manager]" Data source name not found and no default driver specified".

  I added the 32-bit for MS Access ODBC data source I try to use with SQL version 4.0.3.16 with the "C:\Windows\SysWOW64\odbcad32.exe" application developer, but I still don't have the same error.

  I seems that Developer SQL version looking 4.0.3.16.is the 64-bit driver (ODBC Data Source) and I have no idea of directing SQL Developer version 4.0.3.16 to use the 32-bit driver (ODBC Data Source) when opening MS Access 2010

  Thanks in advance for your advice.

  the on-board jdk is 64-bit. To actually install a JDK 7 Java 32 bits, and then configure sql developer to use this JDK

  OR

  go back and get the 3.2 with a JDK embedded sql developer - it is a 32-bit, a

• [4.0] production SQL Developer crashes when you try to extend Java in the browser connection

  People,

  I'm under production Developer SQL on Oracle Linux 5.8 and whenever I click on the link Java in browser connections with a SYS AS SYSDBA SQL Developer connection is suspended.

  Oracle Enterprise Edition 11.2.0.1.0

  SQLDeveloper 4.0.0.13.80

  Oracle Linux 6

  JDK Version 1.7.0_45

  Do the same with the user SCOTT (no SYSDBA) works very well (although there is no Java objects).

  Thank you

  This was noted as a bug.

  The bad plan/performance was recorded as a bug. Developer SQL has not hang for me - I was able to cancel the query using the Panel on the progress of tasks.

• Installation of Oracle SQL Developer and Java

  I finished installing the Oracle Client without problems. SQL Developer opened for the first time and he asks me the full path Java.exe.
  
  That's fine, but when I entered the java.exe I just don't ask again, no errors. Repeat to infinity.
  
  I have the most recent Java SDK installed and tried the 32-bit and 64-bit versions (jdk 7u4). I even tried to install Oracle Client version 11.1.0 AND 11.2.0 to see if that makes a difference, but it is all the same.
  
  I uploaded a screenshot if that helps: http://i50.tinypic.com/mjtqte.jpg
  
  Any ideas?
  
  Kind regards

  Hi Gunnar.

  Documentation:
  http://docs.Oracle.com/CD/E25259_01/doc.31/e26419/install.htm#sthref8

  Ideas:

  -Do not use java7
  -Use JDK JRE not
  -On widows, there is a version of SQLDeveloper, including jdk 6 java
  -Instant client is not necessary - but if you want to use use at least 11.2.0.2
  -SetJavaHome updated to sqldeveloper\sqldeveloper\bin\sqldeveloper.conf to point to the JDK
  -There is some confusion about 32-bit and 64-bit operating systems, java and SQLDeveloper, you can search the forum for more details, for example: put on the title: "Unable to start Oracle SQL Developer.

• SQL Developer Version 3.0.02 really slow to produce results

  Hello
  
  Hoping someone can point me in the right direction here as a SQL Developer on my machine is so slow, that it is virtually unusable (it was not as bad in previous versions but it is possible, that I also have a new JDK since). I open a connection to an Oracle database and the simple type:
  
  Select a_column a_table where a_column = 1
  
  and click on the green triangle (ctrl + enter). The green triangle and the icons of commit / rollback are going gray and I start counting the seconds rough. I arrive at 30 before the result is displayed and I can do anything and yet it says:
  
  All of the lines read: seconds 1 to 0.002
  
  In sqlplus the exact same query returns immediately. I added - J - Dsdev.insight = false to the command line (as it may slow down the Oracle SQL Developer) but this did not help. I'm running Linux Ubuntu 10.10 with
  3353400 KB of memory according to cat/proc/meminfo and my ~/sqldeveloper/jdk file contains:
  
  /usr/lib/JVM/Java-6-Sun-1.6.0.24
  
  quality shows:
  
  PID USER PR NOR VIRT RES SHR S % CPU % MEM TIME + COMMAND

  and this is the only java program I am running.
  
  Any ideas?
  
  Thank you

  Yes, there were "dark ages" for the performance of the SQL Dev queries from 30EA1 and 30EA2 (3.0.02).
  He said that re-encoding on SQL history was to blame for this.
  Unfortunately, there is no satisfactory solution for these versions.
  Try at least 30EA3 and better to have production 3.0 a.

• 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.

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

  Hi all
  
  Currently, I am working with SQL Developer 1.5.1 connection to an Oracle 10.2.0.2 database and it takes about 10 minutes for Developer SQL load. I believe that the problem may be due to the Java Development Kit. I've upgraded to the latest version of last week.
  
  Versions running under 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  true

  After reviewing other posts here, I ran SQL Developer with the console and messages that are as follows:

  I also use a photo of the Web Site, which is not related to my work as Oracle, but for it's photo uploader also uses Java, and which is slow, that's why I think that the problem is based on Java. I would say that the problem occurred in the last two months but has gotten much worse in recent weeks. Developer SQL is slow at times, especially when I used another application and it's just in the background.
  
  Kind regards

  Two things here at first:

  * JDK:
  If you do not remove one sqldev used before, he always uses this one. You can change yourself in \sqldeveloper\bin\sqldeveloper.conf:

  SetJavaHome C:\Archivos programa\Java\jdk1.6.0_10

  Be sue to point to a JDK, however, not a JRE that you mentioned above. Update 1.6.x generally better performance than 1.5.x update.

  * GeoRaptor:
  You installed this extension and it's errors. If you don't need or it doesn't work anymore, better to disable it in preferences - Extensions.

  The NullPointerException in SearchBarAddin is already for several versions, but dev seems not very motivated to solve. Just ignore it.
  If you still see exceptions after checking the JDK and GeoRaptor, or sqldev is still useless, do come back and give some details about the memory usage.

  Hope that helps,
  K.
