• Cannot query the SQL Developer apex_application_files

  Request Express 4.2.5

  SQL workshop

  I use a function table to analyze several files, delimited by tabs, that I downloaded and saved on the apex_application_files.  The strange thing is that when I run the following query in the SQL workshop and the schema that owns the function table, then it returns the correct results.  However, when I try to do the same on the SQL Developer as the user who owns the table function it returns no result.  A short, generic version of the base query is:

  SELECT * from apex_application_files

  Is there some kind of definition I need to put in SQL Developer, that tempt me to appear as a certain user APEX, so that I can get results when I run the above query?

  I was able to get the data I need questioning wwv_flow_file_objects$ of in SQL Developer.

  I don't see a problem with these steps. It is correct. Step 7 is redundant (because of the where you have placed the tnsnames.ora file)-it is only really necessary when you place the file in another directory where +%ORACLE_HOME%\network\admin+ is no longer applicable.

  Note that the customer himself, needs to load the DLL of OIC InstantClient - and this DLL uses the settings of environment and the rest of "do its thing".

  If customer load another customer Oracle DLLS, then bets are open InstantClient is used, never mind will work.

  Only one copy of a DLL can exist in memory. So if some other s/w is using other DLL OIC, then this DLL is already loaded and will be used by all other client s/w. Nothing will be able to use the DLL itself InstantClient.

  Therefore, make sure that no Oracle client driver is loaded at all. Then make sure that when the client s/w requests to load the DLL of the OIC, it is loaded from the InstantClient directory.

  As far as I remember, the core Win32 LoadLibrary() call is made by the application - if the DLL is not in memory, the current (in the virtual machine for this process of Windows) directory is used. If the DLL does not exist there, the %PATH% variable is used to find and load the DLL. DLL usage meter is then set to 1. When multiple processes require the DLL, it is incremented. When a process ends, the usage count is decremented. When it reaches 0, its unloaded from memory.

  Result of all this is that only one module DLL (whatever the number and versions of the physical DLL files on disk) can reside in the kernel space, and you must ensure that the correct physical DLL is loaded by the kernel.

• Need help on Sql Developer 4.0.0.13.30

  Hello

  I need a few suggestions if the underside of features/settings exist in the version of the sql developer said.

  When I open a new connection, a new code editor opens sometimes, sometimes it does not. It should open each time. Is there any setting for this?

  Can I get a list of all currently open windows in a corner of my window of developer sql (like its pl/sql developer tool, in the lower left corner)?

  I can cascade open windows? I can see vertical / horizontal / Float option window, but none cascading is here.

  Thank you

  If you click on the small blue arrow in the top right corner down - it will be on the same line as the list of tabs of the document - it will show you your list of open editors. Windows > Documents will also show you this.

  If you check the links below you can see how someone off 1Z0-007, 1Z0-047 or 1Z0-051 can be used to achieve OCAs either as a developer to DBA. In fact, you can aim for 1Z0-047 (database Oracle 11 g SQL Expert) and win 3 titles from 3 trials.

• The using Excel and Oracle SQL Developer data import - I need help

  Dear friends,
  
  I use Oracle SQL Developer 1.5.1 and I need to import an Excel file into a database table. If I try to import this file into XLS format, fields and headers are properly presented and separated, but if I press the button 'Next', it does nothing - it remains stopped.
  
  I did some research here in this forum and it seems to me that when you try to import a file via the XLS format, Developer SQL has bugs. Is this correct?
  
  If I save the same file in the CSV format and try to import the same file, it moves forward, but SQL Developer is not separating headers and fields correctly. It includes all CSV fields into one - say Column0 and fields 1. TEST; 01/01/2000 under the same Column0.
  
  Save the file in the CSV format is not a problem, by taking a little time. But I don't know how to make Developer SQL import correctly. Could someone help me please? Thanks in advance.
  
  Best regards
  
  Franklin

  This is a known bug in 1.5.1 so use 1.5.0 to import from Excel.
  With respect to the CSV, make sure that you have the right setting in the Preferences - Database - settings of export of genres - delimiter of export custom .

  Have fun

  Thanks for your reply.
  My question is, we would have to apply the hands on review after completing exams Developer OCA to get our certification in post?

  PL/SQL Developer OCA or same PL/SQL Developer OCP have one hand on the requirement of the course.

  You don't need to attend (yet) training for the latter.

• problem starting sql developer 4.1.1.19.59

  Hello

  I installed SQL developer 4.1.1.19.59, but when I start it up it crashes on the login window for the proxy server that is not responding. I can't even shut it down, and the only way is to kill the process with the Task Manager.

  An administrator can run the program, but I'm not an administrator on my PC.

  I'm runnning Windows 7 Professional 64 bit.

  Can someone tell me what permissions are needed to facilitate this run as a normal user?

  P.S. I don't have this problem with SQL Developer 4.0.3.16.84

  Thanks, Wouter

  HI Wouter,

  In fact, my advice was r ide.user.diuse to replace the default user settings folder.  Under normal circumstances the default value of %APPDATA%\SQL developer and the problem is usually an administrative policy that prevents updates records and files in %AppData%.

  My expectation was so you would set ide.user.dir to something other than a folder under % APPDATA %., maybe C:\Temp\OSD, to see if it works.

  Kind regards

• Copy of database SQL Developer - you can copy a database non-Oracle?

  
  I was hoping to use the database copy utility in Oracle SQL Developer 4.0.2.15 to copy data from a sybase database table in an oracle database table. I created both the Sybase and Oracle database connections, however only the Oracle connection is available in the 'Source' and 'Destination connection' lists drop-down in the copy database wizard. Is it possible to use this utility to copy a non-Oracle database, any advice would be much appreciated.

  Assuming that you don't have just to copy a single table (or just a handful of tables), 'copy Oracle"function should appear when you right click on your target table from the Tables node on the sybase connection.

  If you need to migrate tables more this can become tedious, but in this case probably consider using specially designed SQLDeveloper migration functions to migrate all drawings of third to Oracle databases (for this right click on the connection to sybase and choose "Migrate to Oracle").

• How export/import the database from the Tools menu in sql developer.

  Hello
  
  I need to export the database to a server and import it on another server db using the export function of database under the Tools menu in SQL developer. How to import it? This is for Oracle database 10g.
  
  Thank you

  Hello

  You can do it, but I do not recommend because sqldeveloper could eat all the memory of the system to analyze the script. Now the question is do you have also opted for storage option when you export, if yes make sure that similar tablespace exists or available in env b. Also if you want to use the generated sqldeveloper file you can run this file from sqlplus session

  sqlplus newuser/password
  sqlplus > @myexport.sql

  But my advice or suggestion or recommendation to be, you should consider using export/import or datapump but the decision is yours. Hope this helps

• Guard application launch at the start of the appliance, also need advice for the implementation of network methods

  Hi all

  I'm new to the development of Blackberry and I'm writing a relatively simple application to run on 7.1.

  So far the development was interesting, I managed to create my user interface using resources online (mainly this forum), but today I tried to implement some of the network classes that I need and now I just met constant problems.

  I use Eclipse SDK 3.7.2 (the one that comes with the plugin RIM)

  First question:

  I'm not sure what I changed, but today I noticed that whenever I start the Simulator (by sim 9360) my application is started during the initial startup process. I don't think he did this before, but to be honest, I wasn't paying much attention. I think it starts at the start of the device is because I put a breakpoint in the constructor for my class from the main screen, which is hit before the Simulator happens even to the point where it is ready for user interaction. In addition, once it is ready, if I press the BB button, I see my registered application.

  I don't have it set to automatic start in .xml descriptior enforcement.

  I started this application on the HelloBlackBerry sample, here is my main method for the entry of the application:

  public static void main( String[] args ) {
          appSettings = AppSettings.fetch();
          // Create a new instance of the application and make the currently
          // running thread the application's event dispatch thread.
          HelloBlackBerry theApp = new HelloBlackBerry();
          theApp.enterEventDispatcher();
          //openConnection();
  
      }
  
  
  

  As far as I know, this is the only entry point for the application.

  More code

      public HelloBlackBerry() {
          // Push a screen onto the UI stack for rendering.
          mainScreen = new ScreenHelloBlackBerry();
          pushScreen( mainScreen );
      }
  

  Here is the method of. my class AppSettings fetch()

      // Retrieves a copy of the effective properties set from storage.
      public static AppSettings fetch()
      {
          AppSettings savedSettings = (AppSettings) _store.getContents();
          return new AppSettings(savedSettings);
      }
  

  Some of this code that I wrote myself, the persistence store cause the launch of my car?

  I tried to reset the Simulator to the factory settings, no change.

  All applications initialized during the startup of the device and then closed shortly after?

  Part 2: Need advice for the implementation of functions of network in the application

  I need to implement some methods that will retrieve data from a web service, and I also need to send data to this service. What I've read, the ConnectionFactory is the way to go. I want my application to make a request when the application is open and can check on a set interval. I didn't know exactly how to go about adding another thread for networking, I understand that network connections should not be created on the thread main event, so I tried to do this:

  The constructor of my class that implements screen (ScreenHelloBlackBerry), I use the following to create a modal dialog box to prompt the user for a username, I also try networking wire in the same segment of spawning:

          public ScreenHelloBlackBerry(){...initialize fields and managers, add it all together...then near the end
  
  //This will open the confirm dialog when the application is launched
          UiApplication.getUiApplication().invokeLater(new Runnable() {
                public void run() {
                    openConfirmDialog();
                  //start connection - Possibly broken
                    ConnectionThread ct = new ConnectionThread();
                    ct.start();
                }
          });
  

  I don't know if it's somehow OK to do, but it seems to work for what I need. I want a user who launches the application at the prompt, and if a user switch applications, when they come back they wondered again (unless they close the app and reopen it).

  Here is my ConnectionThread:

  public class ConnectionThread extends Thread
  {
  
      public void run()
      {
  
            ConnectionFactory connFact = new ConnectionFactory();
            ConnectionDescriptor connDesc;
            connDesc = connFact.getConnection("http://www.google.com");
            if (connDesc != null)
            {
                HttpConnection httpConn;
                httpConn = (HttpConnection)connDesc.getConnection();
                try
                {
                    final int iResponseCode = httpConn.getResponseCode();
                    UiApplication.getUiApplication().invokeLater(new Runnable()
                    {
                        public void run()
                        {
                            Dialog.alert("Response code: " +
                                          Integer.toString(iResponseCode));
  
                        }
                     });
                    httpConn.close();
  
                 }
                 catch (IOException e)
                 {
                   System.err.println("Caught IOException: "
                        + e.getMessage());
                 }
            }
      }
  }
  

  At the moment it has basically unmodified code from a sample that I found, I'll be retooling to meet my needs whenever I can make it work. I HAD this work to the point where, after the closed user confirm this dialog, a few moments later a an alert dialog appears with the 302 response code. I don't know what changed, but now it doesn't work at all, and if I try to scroll with the debugger, I can't past the httpCon.getResponseCode (). I've seen some mistakes earlier on "no record of service was set up", and I also had once a timeout exception.

  I'm sure I'm doing this wrong, but at the same time as I said WAS working, and now it is not. If someone has done this far, thank you very much for your time and advice are much appreciated.

  Also, should I try to start the thread of the network of the UIApplication class instead of the screen? There is currently very little happening in the class that extends UIApplication, do I spend most of my business logic out of the class of the screen and in the UIApplication class?

  Thanks in advance!

  Hi all

  Just to conclude this topic for those who are interested, I found an excellent guide to the implementation of networks in applications of BB, click here for a link.

  About my application being started at the start of the simulator of the device, I found that on a device real this behavior is not complied with, and in addition, the behaviour seems to have stopped after uninstallation and reinstallation of my Simulator.

  See you soon,.
