• Challenge IOM not accepting questions not answers involving numbers

  Hello

  When we enter the answer to the questions challenge involving numbers, the system throws insert error failure (screenshot below). It works without numbers.

  Is this a bug in the IOM?

  If not, how to avoid this? Please notify

  

  Thank you

  The column for the response of the database table is varchar2 sense it's text, but when you supply a value like 123 (a pure number), the database will think that you are trying to insert an integer into a field of varchar2. Add the quotes will make think it's the text instead of a number.

  This is probably a bug in programming so if you want to get to the bottom of this, raise a SR with Oracle support, but if you look at the example in more detail, you will notice that he asks for one more month and given suggestion shows the month written in his full name, so in theory if you have followed the example, the answer would be not only a pure number.

  To work around the problem, you can customize your form validation and always add quotation marks to the input values.

• General question: what is involved with a DBA position entry level?

  Hello
  
  I hope I've put this in the right forum. I was hoping to get feedback by those in or near the field to get a better understanding of the responsibilities and requirements for entry level DBA work. (What is a "I need a job", I did not).
  
  I don't know there is a wide range of difference depending on who you work for. So, I guess I should post a more specific question, if any feedback is greatly appreciated. I don't need to know it is to meet the education requirements, I have that down.
  
  Number of questions:
  -With an "entry level" position, commonly how one should be in SQL and PL/SQL?
  -Would you spend more time working on isolated tasks, or management of database encompassing all the?
  -One would spend time to work in other languages?
  -Would one spend a lot of time on the architecture and design of DB?
  -Other than the server (and associated material general network) is there any other material can be expected to work with?
  -"Beginners" would require a vast maintenance, troubleshooting, and hours of coding?
  -In general, is "entry level" a post of Assistant?
  and finally
  There's anything like that, you wouldn't expect not as a requirement, but is often in the field. Such functions often passed down that one would not expect, or additional skills that would be expected not to in general.
  
  Thanks in advance for any comments. Feel free to include comments not mentioned in this post. I must add that I have a solid knowledge of google, but I'm hoping to get previews experienced (at all levels).
  
  Thank you

  Is pretty much answered your questions

  It depends on.

  It depends on what you know already - master (or at least become quite good at) before entering the DBA work.
  It depends on how your store is set up.
  It depends on what is needed at the moment.
  It depends on if the shop you can (has a place for you) with your skill set.

  There is no standard for what makes a DBA. Not really. No s/n, at least no that last a very long time, never turns down a task because it is not DBA job to do. Therefore, the best DBA (very useful) are quite versatile in what they know and what they do.

• Question about the interface inheritance & documentation

  If I Foo interface that extends the interface bar, I wonder if there is a way for Foo add more documentation to one of the methods of the Bar.
  
  For example, if I have:
  

  public interface Foo {
   /**
    * The "stuff" that gets done by this method should be more properly defined in the implementing class. 
    */
    void doStuff();
  
  }
  
  public interface Bar extends Foo {
  
  }

  Is it possible for me to clarify for Bar to replace the doc on the legacy of Foo doStuff() method (such that it could read something like ' all implementers of Bar doStuff() method should [behave in manner x] ')?
  
  I know that I am probably not articulating myself very clearly, so let me know if I need to shed light on what it is.
  
  Thank you!
  
  Edited by: Caryy on November 30, 2010 16:06

  I think that you are authorized to declare a method identical doStuff() Bar and give its own documentation. He will not just get concatenated to doc supertype, but the javadoc tool could generate a link to the parent method as it does when a class overrides or implements a method.

• fundamental question of OOP.

  Hello, can someone explain why the value keeps returning an undefined value?
  this.speedX and this.speedY are not defined.
  
  in the source file, I used to instantiate the class:
  
  var test: csmove = new csmove (circle, 2, 2);
  
  

  If you use AS2 when you set the onEnterFrame upsdatepositie
  the scope of this function is not for your class. to ensure
  that you use Delegate.create

  ...
  Import mx.utils.Delegate;
  ...

  function movenow() {}
  this.targetMC.onEnterFrame = Delegate.create (this,
  This.upddatepositie);
  }

  and if you want the targetMC keep moving inside the updatepositie
  You should have

  targetMC._x += this.speedX;
  targetMC._y += this.speedY;

  hope this is useful

• Computer cannot find the printer on the network

  I have a Photosmart D110A and use a router Airport Extreme to print from my PC and iPad.  Until a few days ago, it worked fine but now neither my iPad or PC can find the printer on the network.  When I run the test report of network on the printer, it shows that everything is fine and dandy.  No the guided HP solutions even to get close to solving this riddle... it seems that any questions they discuss involve the printer will not connect to the network.

  OK, so they are both on the network of comments.  Comments network does not allow for communication between devices.

  Open Airport utility, select your airport and click installation manual.  Access to the Internet zone, then DHCP.  What are the two structures IP DHCP for your two airport networks (invited and regular).

  For example, mine is 10.0.1.X for the ordinary and 17.16.42.X for my network of comments.

• Printing problems HP Officejet 4500 and warranty issues

  Help!

  I have problems with a HP Officejet 4500 that I bought last January.  He stopped working at the end of December, but I had to get out of town for Christmas and have not reported in time.  It is not my main printer, so I didn't start working to try to make it work until today.

  It will start printing, but stops after a few lines, the screen indicates that it is out of ink.  Sometimes he says that the black ink is low, sometimes the tri-color, sometimes both.  After I have the OK button it will print another line or two until it stops and says it's out of ink.  What it prints, it's kind of uneven and blotchy.  Sometimes it falls a letter of a Word.

  When I run a report it wybody help best cut down the lines.  For example, if the line is different sizes of the 'Aa' letter, it will only print the top of the letter.  He will also skip lines.

  I cleaned the cartridges, I aligned the cartridges (that I did when I put these new cartridges), and I'm at the end of my mind!

  Can someone help me or am I just bad luck?

  Thank you!

  I would like to look at this document here. It will give one the troubleshooting steps to try to resolve the problem you are having with a quality of printer output. Among the measures here are ones you mentioned by train, but there are others in the document which are available and which were not included in the above post. If you reach the end of the document, and the question is still involved, would seek the replacement of the product.
  
  If you are still in warranty, HP can replace the printer without cost to you. I'll link the information to get in touch with them below. The link takes you to a form to fill out. Once you fill it and she is treated, it will give you the printers warranty information, a file number and the phone number to call.

• Satellite Pro 4600: How can I get my wireless to turn on?

  EIS,

  Sorry to ask the most basic questions, but I just inherited a Toshiba Satellite Pro 4600, on the back side of the laptop, I have the following information:
  CEL 750 / 128 / 20 GB / 14T

  On the left side of the Panel, there is a wireless - switch this switch, how can I get the built in wireless to work please?

  Thank you.

  Hi mate,

  Firstly: are you sure that you have a wireless card installed? This is the first question and perhaps the most important of them. Not every Satellite 4600 has been bundled with a wireless card and a switch wireless on the left side says nothing.

  I know it s hard without technical knowledge, but what you can do is download the drivers from the Toshiba Drivers and Downloads 'Archive' wireless, turn on the wireless switch and check if some materials are recognized. If Yes, then welcome to the wireless world. :)

  Would like to hear some comments from your part Thx.

• Satellite L30 - 11 d is not recognizing the full RAM

  Hello

  I have a Toshiba Satellite L30 - 11 d, as shown in the subject. I had the laptop for a year before, I decided to move the ram to 2 GB. In 2008, I bought a RAM 1 GB DDR2 5300 AENEON chip and another microphone technology DDR2 5300 s 1 GB RAM chip.

  These two circuits are compatible with my laptop. These two circuits work in the two slots of RAM and CPU - Z can confirm that there is 2 GB of memory in my laptop. However, Vista was unable to register for 2 GB, instead it sees only 896 MB of RAM. After a few months of frustration, I decided to downgrade to Windows XP Professional to see if she could remedy the situation and allow my life become a little more smooth. However, the same question is still involved.

  Literally 10 minutes ago, I confirmed that these two circuits operate in the two slots of RAM and CPU - Z can confirm that there is 2 GB of Ram in my laptop. BIOS, graphics and all other drivers I can enter on the Toshiba site has been installed and it's really just leaving me completely stumped. If someone has any ideas as to what could be the problem, it would be highly appreciated.

  Thank you for your time,

  Ash.

  It's very strange
  Also the shape of most recent BIOS, from Toshiba Web site is installed did you say?

  Have you tried to use two modules of the same production? I think it is the reason for this. Notepad starts with the two modules, ok, but I think that must be the reason for this. In your case I would test it with two modules of the same production.

  In addition, the video RAM is shared with the RAM. Then don t forget you can use 2 GB only for main memory.

  Sorry, but at the moment I can say s.

• 2 replicated domain controllers or clone 1 DCs as cold standby

  I don't know if this is the right forum to ask this question or maybe someone can divert my question. Any involvement of a Windows 2008 Server cold waiting without any network connection for a period of time, tombstone question? and the reason that I asked for, it is I think to perform replication from domain controllers 2 where 1 fail and 2nd DC to support, or just to clone standby and connect the network whenever the 1 domain controller fail.

  Appreciate any comment.

• Remove the auto to replace new installed XP Pro search function, whenever I try to open transferred files/documents

  Hello all him world-same advisors windows on this forum:

  I thought I had posted this slight question here, but maybe on other forums of Web site...  I could not find in this forum, throughout 50 not possible pages to be sorter for the dates of entry anywhere to locate mines. So, I am apologically, submit again (if I already posted here).

  I prefer my implementation of behaviors on my programmed replacement XP computer to be what I'm used to.  My old computer was XP system (do not know if a Home or Pro).  Whenever I have clicked/open a saved folder and/or its documents/pictures, etc., he immediately opened everything I wanted.  Very simple and the most privileged.

  This computer has been changed by a virus (HDisc has been cleaned) and breath of capacitors (?).  I replaced this computer with a similar XP programmed order.  This computor (Lenovo) is installed with OEM XP Pro (Service Pack 3 2002).  My cleaned documents and records were transferred to this computer.  They are also on my external hard drive. All resettled programs worked / I was able to run everything as I preferred, and I know my game previous changes.

  The new computor will now automatically in the search window (I got rid of this infernal animated dog) whenever I click/point on a folder and or any document in this folder.  I now do a right click to open the menu, scan down to go to search, explore, open and click on open every time I want my stuff with immediate access. I went and variously adjusted/delete/restore items separated and grouped in file search options. No effect I wanted, then it's back to the restored original basis.

  Does anyone have a simple solution for a keen memory private user of documents and folders to open the first time I point to them, without having to the Group of experts through 2-3 additional steps to counter some automatic placement in a research program?

  Thanks for the reply.  Method 1 as fact: click Start, control panel (click appearance and themes is not in this Panel) then you click on options files, display tabs, then erased automatically search box of files network, apply, and then click OK.  No effect.  When I click on registered (non-shared, never networked shared, in a single computer only) folder, the search engine appears and indicates to click on in the box on the left to share.  It brings up a list.

  I want my file to open it in mode icon in place, what it does when I go its just clicked menu to open.

  Method 2: start, press go to run, should have read clicked ok, locate items in step 2 (through the menu items open progressive as indicated), when in the value DWord, when started banging NoNetCrawling he immediately travelled to this window and in box will the number 1, which was already. This spruced up, press OK and the closed registry editor and start box.     Once again, no change in behavior.  Go back to defaul restoration, since it is the basis for me to start without jump my computer up to my forgotten violin.

  Thanks a lot again.  However, responses to my question don't involve any networking computors, shared, wifi /, household D link wireless routers, office or home setting or use dial-up.  It is a computor that whenever I point to a folder, the search procedure starts automatically.  I want this behavior stopped and I want the computer to open the folder and the files it contains right now I click on it (I use the simple click).  Click and open.  Don't click, search, open.

  How can I find my question?   I went to the discussion for XP, all questions and did not find it anywhere among the 50 items recently answered to.  Only it obtained pressing the issue on my e-mail address containing your answer.

• Cannot print with HP Officejet R40xi

  I have recently switched to a computer running Windows 7.  I got the cable from the printer to make it compatible USB.  The printer is and the convenience store says it very well, but I try to print every time, I get an error.  I can copy on the machine and the copies are great so I know the printer works.  What I am doing wrong?

  Hi as1.

  The question is probably involving parallel to USB adapter, so a better solution would be to add a port to your computer.  I checked and add on cards can be purchased in the range of 10 to 20 dollars.  This would require a desktop computer.  If you have a laptop, you may need help of the parallel until dealer adapter USB.

• forced upon restart OS choice

  Continue to address the issues on my reinstallation of windows XP Pro Sp3 on HP d4650e desktop. led to this question of the 2 part. On reboot I get a black man with a white police asking me to choose what operating system I want to open. It's 2 selection of the same I just reinstall. The only option, the screen offer is somewhere else on Earth 'F' where the options are Boot or restore to the last working configuration.

  When replacing only two programs cannot be copied or installed, and I had to go around them. They were C:\$WIN_NT$.˜LS\1386/property.dll, this was before the partitioning. Then after partitioning sequence he wouldn't copy the file property.dll then later with ahcix86.86

  That this has something to do with it? I don't know, maybe not. All I know is that it was the only strange thing that occurred during the process. I save as much as I could from system on external hard drive until...

  Nevertheless, I'm really sorry, my question is so involved, but I have little recourse. Mega Bravo await you.

  Try to start with a utility cd to delete all partitions, create 1 partition & format hard drive. I had good results with the free Partition Wizard. Scroll the page & download the iso to Bootable CD here ! Download ImgBurn here to burn the image to a cd.

  Once all operations with made PW try to boot with your XP disk again. Be sure to disconnect all external devices such as printer, wireless adapter, etc. Just kbd, mouse & monitor attached. (You can also use the test drive included in the cd PW)
