• Connect to the Oracle database - does not connect

  I am new to JAVA and for the first time that I am trying to connect to an Oracle using JAVA data. Well, I get an error when you try to connect to the database.

  The try section runs very well but only partially because you get the exception "ClassNotFoundException", which means that it is impossible to load the Oracle driver class (so it does not reach the line where it says):

  Class.forName(driverName);
  

  You intercept this exception and then simply print a line "could not find the database connection: null". Then you let the code continue, obviously without you still initialize your variables.

  I would recommend rewriting those catch blocks throw new RuntimeException so that the code will not continue any further when an error is detected in the try or don't catch not all of them if you donot want to manage them appropriately.

  As for your problem, you probably have not added the ojdbc14.jar is to your project, and this is why it cannot find the class OracleDriver.

  Finally, try adding {noformat}

  {noformat} around your code when you post code.  It makes it a lot more readable.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
  

• Listener (and the database instance) does not start automatically: ORA-12514: TNS:listener does not currently of service requested in connect descriptor

  Hi all... I am a newbie with oracle database.,.

  I have the problem of monitoring:

  I installed Oracle Database 11 g R2 XE on my CentOS 6.5 guest operating system.

  I changed the host name in my CentOS so (where installed oracle 11g R2 XE) after the installation was completed successfully.

  Installation-) before and during the hostname is localhost.

  (-) After the installation, I changed the host name in VMCentOS

  From the moment where I changed the host name, nothing starts automatically. In particular, the listener and the database instance does not start automatically.

  When I start the listener manually and I try to connect to the instance of database with SQLPLUS I get this error:

  ORA-12514: TNS:listener is not currently of service requested in connect descriptor

  I think that the problem is due host name changed because I have to test and debug the object, re-installed a machine virtual operating system CentOS, re-installed oracle database 11 g and I do not have this problem. The database instance and the listener starts automatically!

  Can someone tell me if, maybe, the problem is with the host has changed? ... and why?

  P.S.: After changing the hostname I also modified the listener.ora and the tnsnames.ora by changing the HOST with the correct host name.

  Hello

  It seems that you don't install Oracle Database Express Edition (XE). If you post this question in the wrong forum.

  When you install EA or there is no script that starts the database at startup.

  If you wish, you can create by yourself. For example search for instructions to Google how to create script.

• Completed tasks remain in the queue, subsequent job does not print.

  Queue says 100%, but it never goes away.  If I put the computer to sleep, it prints a second copy of the work "completed" (even if only one has been specified.  If I have a second job in the queue, it does not print until I have manually delete one (a troublesome task with several jobs to print).

  I tried a few suggestions that I found these boards of Directors, including the removal and re-adding the printer, printing (Option-click) system reset, unplug the power cord and plug and unplug the USB cable and reconnect.  None of these things has eliminated the problem.

  I can impose by the experts here to suggest something that I might have missed?

  I recommend you only uninstall the HP software using the "scrubber":

  Go to Applications/Hewlett Packard / click Uninstall HP
  Click on continue
  Highlight your device in the left pane
  Press on and press and hold Ctrl + Alt + Cmd keys on the keyboard at the same time as you click on uninstall, it IS the Option of the scrubber, no button is labeled "washer".
  There will be a pop up that asks if you are sure you want to uninstall all hp software. (At this point, if you continue, all HP printers you have installed will need to be reinstalled)
  Click on continue and let it finish

  Download and install this: http://support.apple.com/kb/DL907

  Restart your Mac.

  Now reset the printing system:

  -Sys Prefs, Print & Fax
  -Right (control) click inside the box that lists your printers and select Reset Printing System.
  WARNING - This will remove ALL your printers!
  -Select the sign + to add again. Search for the printer, select it, and wait until the button 'Add' becomes available. Until it clicks.

• DBMS_SCHEDULER job does not start if use_current_thread is set to false

  Hi all

  I'm trying to run a job (via sqlplus) by typing:

  dbms_scheduler.run_job exec ('jobname', false);

  I see:

  but the task does not run. If I change from FALSE to TRUE, it rotates - but of course my session will have to stay connected.

  The work has a program (which is a PL/SQL block) and the calendar set.

  Hmmm... seems that you must specify the schema name if you are not using the current thread. Now that I think about it, it makes sense... I'm leaving the scheduler does not define the default schema (or does not really like the user?) when running in the background and does not find the job, that's why run_job ends but nothing appears in the use of the term paper because it was never found in the first place.

  It is also interesting that instance caged features differently... no instance caged during parallel execution using the current thread. For example, caged when not to use the current thread.

  Hello mpm068,

  Thank you for using communities of Apple Support.

  Since your iSight webcam works up to the time that your Mac goes to sleep, I would like you to start please help desk trying to replicate this problem then to reboot in safe mode:

  1. Choose the Apple menu > shut down.

  2. After your Mac stops, wait 10 seconds, then press the power button.

  3. As soon as you hear the startup tone, hold down the SHIFT key.

     You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.

  4. Release the SHIFT key when you see the gray Apple logo and progress indicator.

  To exit safe mode, restart your Mac, but no press during the startup.

  OS X El Capitan: start in safe mode

  Take care.

• AiOSoftwareNPI (* .ms) the Setup program does not start when I start my computer.

  original title: AiOSoftwareNPI

  I'm having a problem with a software AiOSoftwareNPI problem (* .ms) the Setup program does not start when I start my computer.

  I know it's a Windows Installer but I don't have a disc with this route. I even tried to reinstall the windows xp disk and it does not work, I still

  Thank you

  Ms. C

  After doing a Google search for AiOSoftwareNPI and followed by the reading of many different threads in various forums, I found that it is for drivers for an HP all-in-One printer.

  You have an HP printer?

  If so, the usual suggestion was to place your HP printer disk in your CD/DVD drive and restart. After reboot would be installed the necessary files and the pop - up would more appear at startup. I don't know if it will actually work because in all the discussions I've read, none of the original poster never responded by saying that it worked or not.

  The next most common suggest was to download the latest driver for your HP printer to your version of Windows (including at the level of the ILO) and install it. Yet, not a single original poster has responded.

  In fact, if you have an HP printer I suggest to visit the web site of HP support below the link to get the latest drivers and their installation. Visit the support for the correct installation method and if you need to remove the old driver first. You can also visit the communities of Support HP for assistance (a link for communities is also on the next page).

  My laptop started running very slowly and I can't seem to start the Task Manager. Ctrl alt delete gives me the opportunity to start that I chose, but I don't get an inactive icon in my toolbar. I am running vista Home basic with service pack 1. When I restart or stop the laptop hangs at logging off-page. I also noticed that some of my applications/startup process are not start or appearing in my toolbar. I initially had Bit defender as my anti virus - but he exchanged for computer related. I had the problem with both.

  Hi Omanianne,

  Please read the following article from Microsoft Help on the Troubleshooting Task Manager.  Specifically, look at the sections of the Task Manager does not start, and How to enable the Task Manager if it has been disabled.  Based on the other symptoms you have described, it is very possible that you have some kind of virus.  Please make sure that your antivirus software is up to date and run a scan complete your system.  Please let us know if you have any problems or questions.  Thank you.
