• the basic sql question

  Hi all I have a basic sql question
  Watch below two querries
  

  1.  select 1 from dual where 1 in (select 1 from dual union all select null from dual) 
  
  It gives output  as 1
  
  but below one 
  
  2.   select 1 from dual where 1 not in  (select 2 from dual union all select null from dual)
  
  It gives output as no data found 

  I think as operator will not compare with all the values, but not the outcome it will compare with all values... When comparing with the value null, the result is automatically null
  
  I'm wrong
  Please help me on this
  
  and why performance wise in operator is more better than no of?
  
  Thanks to all in advance

  Thanks for posting your explain plan command

• VPN connection question

  In my workplace, there are two networks is the local LAN that connect other computers to the internet and the wireless network which my computer connect to and is directly to the internet, my question is that is it possible to connect to the LAN over the internet using the connection V P N if yes how? Please help me because whenever I want to read my emails, I have to put the UTP cable which will be sometimes annoying.
  Please indicate all the measures that are needed to establish the VPN connection.

  Ask it professionals about your place of work.  They know what is possible and what is not.

  Where I work, there is an available VPN that allows connections to the LAN from outside work.  If I use a laptop computer provided by the company, access the LAN just as if I'm at work.  If I use my PC, I get a link that allows me to access a limited number of resources, such as the email of the company.  I can, however, DRC to my desktop at work PC and can get access to the local network.

• Basic PCMCIA question: where is the controller?

  Hello people,

  I have a basic question of the PCMCIA:

  The PCMCIA controller is integrated on the motherboard or does the PCMCIA device?

  Practicality: if I want to change the PCMCIA in a laptop, I can change everything (part mechanical + electronic) or simply the mechanical part?

  I have a mono-emplacement controller, and I would have a dual slot PCMCIA. If the controller is on the motherboard, I have no chance of success.

  Thank you:

  UB

  The controller is on the motherboard. Pcmcia slot unit is removable, as stated above, but it's just a cage to hold the cards... no chip is in it other than a plug-in interface on the motherboard which channels to the pcmcia controller.

• Carrier - installation and basic connection issues

  We have never used or installed the front carrier.  We currently use Tidal 5.3 x and a sandbox to 6.2 upgrade.  I looked at all the documentations of carrier I can find or miss me even a few very simple questions - more I can't "help" to the carrier to work.

  1. WHERE to install the carrier and why?  CM server?  Master Server?  Desktop computer?  If it's on a server, then should the user executing remote server in order to transport the user?
  2. I have tried to install on each of the above, but a connection could not be.  When I click on 'test', I get the error "Failed to Connect [failed to connect with responseCode [404]] what should I be entered in each of the areas following connections?  My comments indicate that I assumed/attempted to enter and received the above error.
  • Name of the connection - just a name given to a connection? aka TESSandboxMaster
  • Server - server name?  master?  Y at - it a specific format, in that it must be?
  • DSP/Plug in name - I found a dsp on my CM server file named YOUR - 6.0.dsp - should I put YOUR - 6.0 here?
  • User - user of the network which is a Super user of tide?  aka networkname\superuser?
  • pwd - pwd for this user windows?

  Thanks for any help you can provide.

  Hi Patricia,

  1. the carrier is installed on the Client Manager - CM is essentially a web to manage the demands of customers, orders sacmd and Server utility for the transport of jobs from one environment to the other. A tide user should be given rights to move Production jobs, and I think tide user must be able to sign the cm as well.

  2. I looked at an older copy of user guide 6.1 carrier provides instructions on how to complete these fields:

  To create a connection: (on page 32)

  • In the connection name field, enter the name of the connection file.
  • In the server name field, enter the name of the Client Manager machine.
  • DSP/Plugin name, enter the name of the primary instance.
  • The name of the primary instance is the name of YOUR DSP or Plugin. It is displayed from the user Web interface in master status pane.
  • In the Server Port field, enter the Web Service used by the Web Client tide listening port. The default value is 8080 for unsecured connections and 8443 for secure connections.
  • In the user and password fields, enter a valid Business Planner user name and a password.
  • Select the secure HTTP option if you want to connect safely through the HTTPS protocol.

  This option is only enabled if the carrier has been configured for sure
  connections. Figure 8 is an example of a carrier not configured for sure
  connections.

• Wire Vs sleep Vs MDS Http connection Question

  Hello

  Here's my situation...

  I created a thread for background based on this article:

  http://www.BlackBerry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800451/800660/How_To _...

  Here is my code:

  / * Thread that runs in the background * /.
  the final private class BackGroundThread extends Thread {}
  private static final int TIMER = 15; minutes
  Private boolean _stop = false;

  public synchronized void stop() {}
  _stop = true;
  }

  Private boolean isCoverageSufficient() {}
  If ((DeviceInfo.isSimulator ()) |)
  (RadioInfo.getState ()! = RadioInfo.STATE_OFF & (RadioInfo.getNetworkService () & RadioInfo.NETWORK_SERVICE_DATA)! = 0) & {CoverageInfo.isCoverageSufficient (CoverageInfo.COVERAGE_MDS))}
  Returns false; a Simulator or a real device with sufficient coverage
  }
  Returns false; real aircraft with insufficient coverage
  }

  public void run() {}
  CoverageInfo.addListener (new CoverageStatusListener() {}
  {} public void coverageStatusChanged (int newCoverage)
  {Switch (newCoverage)}
  box (CoverageInfo.COVERAGE_CARRIER):
  System.out.println ("COVERAGE_CARRIER");
  GPS.this.sendPoints ();
  break;
  box (CoverageInfo.COVERAGE_MDS):
  System.out.println ("COVERAGE_MDS");
  break;
  box (CoverageInfo.COVERAGE_NONE):
  System.out.println ("COVERAGE_NONE");
  break;
  }
  }
  });
             
  While (! _stop) {}
  GPS.this.getPoint (); try to get a GPS point
  Make sure the radio is on and there is the coverage of the data
  If (isCoverageSufficient()) {}
  GPS.this.sendPoints (); Send the _Dans table to the web server
  } else {/ / blackberry is out of coverage}
  GPS.this.storePoints (); store the table _Dans on blackberry
  }

  try {}
  Thread.Sleep(Timer*1000*60); pause the thread for a set number of minutes
  } catch (InterruptedException ie) {}
  System.Err.println ("Error:" + ie.toString ());
  }
  }
  }
  }

  The 'getPoint()' method to get a coordinate GPS using LocationProvider.getLocation ().

  The method 'sendPoints()' send the GPS coordinated to a web server using the HTTP connection:

  ...

  HttpConnection con = (HttpConnection) Connector.open (URL); Open the connection URL
  con.setRequestMethod (HttpConnection.POST); POST method
  con.setRequestProperty ("Content-Type", "application/x-www-formulaires-urlencoded");
  OutputStream out = con.openOutputStream (); display the results in a stream
  out. Write (Data.GetBytes ());
  int responseCode = con.getResponseCode (); Send data and receive the response code
  If (responseCode == HttpConnection.HTTP_OK) {}
  success
  }
  If (con! = null) con. Close; close the connection to the URL

  ...

  The "storePoints()" method simply store the GPS on the Blackberry Persistent Store when the BB is out of coverage.

  When the Blackberry is trying to send a GPS coordinate, but cannot because it is out of coverage, GPS data are stored on the Blackberry. My thread can sleep for 15 minutes before getting another coordinated GPS. If the BB is on the cover in the next interval of 15 minutes, the two coordinates are sent (the current and that (or those) that have been saved on the device).
  It works very well.

  However, now, I would put up a CoverageStatusListener so my GPS coordinates would be sent as soon as the BB is on the cover (and not wait for the next 15 minutes).
  I tried to "COVERAGE_MDS", but he never seems to have triggered... but gets "COVERAGE_CARRIER".
  I have a post on this here: http://supportforums.blackberry.com/rim/board/message?board.id=java_dev&thread.id=6076

  My question is on the wire. Actually here is called the 'sendPoints()' method:
  box (CoverageInfo.COVERAGE_CARRIER):
  System.out.println ("COVERAGE_CARRIER");
  GPS.this.sendPoints ();
  break;

  However, since my son sleeps, this method is not able to initiate a connection HTTP using MDS. I get an error in timeout after 2 minutes.

  I'm not an expert on the threads. I think I have all the necessary parts of the code... but I'm not sure about how to reorganize this.
  Can anyone help?

  Thank you!

  The network connection should be asked by a listener method.  Do not perform any operation or the heavy within a method of transformation of blocking listener.  Instead, you can create a new thread from the method which could then create the network connection to send your data.

• Basic VMWare question

  Hello, people:

  Please forgive my very basic questions, but I'm totally new to VMWare.

  Yes, as a R & S Cisco engineer, I worked with server

  specialists to get their online environments, but my focus was on the

  network component, from the access layer.

  Anyway, when you create a virtual machine and associate a request,

  This virtual machine has an IP address assigned to its own vNIC?  So, if it

  5 virtual machines run on a physical server, the number of addresses IP are you going

  have? How the allocation of an IP address of the physical NETWORK adapter is bound to the

  others?

  Once again, thank you for your help in advance.

  Take a look at the document I linked in the previous post.

  The virtual network is based on vSwitch which are "dummy" brigde.

  So has each VM's own MAC address (which is virtual and the part of the seller is dedicated to VMware).

  A physical NETWORK card is simply an uplink to the physical switch and the physical MAC address is generally not used and not visible in your network traffic or your ARP table (think a unmaged switch, it can have a MAC address, but you don't see it on your network).

  When you have several (more than one bear on a vSwitch) uplink you can have different types of team policy.

  (For you is probably the simplest to understand) is like the etherchannel on Cisco switches (and it takes a good configuration of the physical switch).

• Two guests of virtual machine running in Bridge Mode connection question

  Hello

  I seem to be a little lost with a problem.  What I've read, VMWare Server is free (I plan to use it in a test environment, which is low-budget).  I installed on a server and got two VMGuests of installation at the moment.  The question I have is that I don't see the first guest that I boot on the network at any time? Anyone who encountered this?  that is, if I start the server A and Server B then, Server A is located on the network without problem but can't change anything to or from Server B.  If I stopped server server B still does not work.  If I stop the server B and then start up with the server still does not, it will work on the network.

  At first, I thought that because it's free it will allow only one server at once, but I don't think it's true.  The only other thing I can possibly think, is that I just copied a basic virtual machine Image I created so that both servers are at the same image.  When asked if I had copied from moved it I chose move, this might be the reason, and I need to select copied?

  Anyone got any ideas please?

  Kind regards

  Wayne

  Looking for a line like the following, with a text editor in the file .vmx for each of your virtual machines:

  ethernet0.generatedAddress = "00: 0C: 29:b2:04:03.

  There may be several entries being Ethernet if you have multiple network cards. That's how the MAC address is set and must match what ' ipconfig/all' or 'ifconfig - a' shows you in this prompt.

  MAC addresses are not totally free but you can manually change the lowest few bytes (for example the 03 to 05 in the example above) or a more correct way is to add another NETWORK card and then delete the original, a copy.

  When you reach the point of having the 'model' virtual machines - where you copy the files manually to a new location to create a new virtual machine - and then add the following line to the .vmx to avoid this problem doesn't happen:

  UUID.action = "crΘer".

  Thanks for posting this; It is very useful.
  Do not attempt to INSERT a VARCHAR2 (like January 1, 2011 "") in a DATE (such as start_date) field. Even if the above instructions to INSERT work today on your system, there is no guarantee that they will work on the system of someone else, or that they will work on your system in the future. Use TO_DATE or a DATE literal to INSERT a DATE.

  Here's a way to do what you asked:

  SELECT     key_group
  ,     CONNECT_BY_ROOT start_date     AS s_date
  ,     end_date
  FROM     test_connect_by
  WHERE     CONNECT_BY_ISLEAF     = 1
  START WITH     (key_group, start_date) NOT IN
                      (
                    SELECT  key_group
                 ,     end_date
                 FROM     test_connect_by
                 WHERE     end_date     IS NOT NULL     -- If necessary
                )
  CONNECT BY     key_group     = PRIOR key_group
       AND     start_date     = PRIOR end_date
  ;
  

  Whenever you use a NOT IN subquery, make sure that it never returns NULL values. If end_date is a NOT NULL constraint in your real of the table, then you don't need the WHERE clause of the subquery.

  Whenever you have a question, always say what version of Oracle you are using.
  This is particularly important with CONNECT BY queries, because each version since Oracle 7 has had significant changes in this area.
  The query above requires Oracle 10.1 (or higher).

• Basic Actionscript question: mouse listener ROLL OVER event

  Hello-

  This is a very basic question, but I can't seem to find an answer. I have a mouse over the event and have created the buttons with the mouse overs which works very well. I created the actionscript code to go to a specific web page when a user clicks the button. Now, I need to add a label to the mouse more then when someone of the mouse on any area of the button, it will show them a particular name for the button.

  I'm sure it can be done using actionscript in a mouse event run on command, but I can't understand what I need to display the text. Here is where I am:

  community_btn.addEventListener (MouseEvent.Roll_Over, showmsg);

  function showmsg(evtObj:MouseEvent):void

  {

  }

  Thank you!

  If you want the text to follow the mouse, you can have a movieclip that contains the textfield object is empty, and when you rollover the button, the function of turning tells that movieclip to take the x and y position of the mouse (mouseX and mouseY) and fills this movieclip with the appropriate text.  Roll off the button removes the text, making the invisible text movieclip.

  If you want the text to have a background, you could also control the visible from the movieclip property so that it appears on rolling and disappears when you deploy.

  Thus, in the reversal function, assuming that you had this ToolTip named MC... "toolTip", soimething this might work for you

  toolTip.x = mouseX;  could add a little space if you want, for example: mouseX + 5;

  toolTip.y = mouseY;

  toolTip.visible = true;

  toolTip.tField.text = 'text ';

  And implementation code to would have to deal with the last two lines.

• Pretty basic Calc question... I think so.

  I think this question is PRETTY Basic. So we all know that the data is located at the INTERSECTION of dimension members. Therefore, you can not say that the data is a single dimension not more that he is sitting in another dimension. Which means that, if the data is found on the account "xyz" for the year of "FY10"... it would be the same as saying my data is from the year "FY10" on behalf of "xyz".

• Podcast connect Question

  How to ask for help on a podcast from iTunes, if I presented the show per person interposed as Libsyn - and not iTunes? I need to create an account just for this - or can I use my Apple ID?

  I production-edition two shows. We have a missing episode. The other is a not yet post in iTunes, even if it has been almost two weeks. I read on this forum where I can ask a 'refresh '. Question - what I have to have a specific account to ask for this help or my identifier Apple will work for this purpose?

  I talked to Libsyn and they say to be patient. I'm just trying to do everything possible, because podcasters themselves are not happy.
