  Have you ever tried to force reboot the phone by holding down the button sleep and home for 10 seconds, until the call logo comes back again?

• What is the best solution for this idea...

  I have a task I'm trying to test and understand what would be the best solution for this, any recommendations would be appreciated.

  Devices at your fingertips:

  -2 ESXi hosts

  -1 iSCSI SAN OpenFiler (new just installed the app)

  2 ESXi hosts run a small amount of virtual machines that are all in the same domain.  I want to have a file server (or a repository somewhere) that houses a folder with easily accessible software (OS, Office, etc.) on the field.

  According to me, that if I made a virtual machine with a large hard drive and share the software, this would not be the best way because it would be dependent on the OS.  Someone has talked about doing a separte VMDK for it and then install it on the operating system on the virtual machine. This way I could always remove the and mount it somewhere else.

  It seems a bit weird to me that the software within this "shared folder" will also be sitting on the data store (if I create a virtual machine and need to use the OS/etc).  Not that doubles the space for the same software (in the comments, then the data store)?

  What is the best approach to make this action which can be accessed at the prompt (mostly windows) in the field?

  What is the best way to stay away the software doubles in action and on the data store?

  Please forgive me if I put interpereted your question.

  The problem you seem to face is that you must mount the ISOs of VMS software and physical systems that are on the field.

  (please, correct me if I'm wrong on this)

  If this is the case, then the best way to do would be to create sharing NFS on the openfiler, if you use openfiler to main databases also then he would be better for sharing this was separated to prevent the other help to be able to tamper with the VMDK and VMX files for your virtual machines.

  This could then be mounted in ESX to access the ISOs. While being easy to install on Linux and Windows machines to access the ISOs.

  If you have questions about NFS mounting in windows, so, this link may help

  http://sagehacks.WordPress.com/2009/01/21/HOWTO-mount-NFS-shares-under-Windows-7

  If you are needing to access the VMs software and it is mainly the downloading ISOs then th ISO directly to the data store is possible.

  This allows you to use ESX to mount the ISO on the virtual machine.

  On the point that the software will use double disk space when you install the software on a machine virtual car will be on the network share and the VMDK virtual machines in the data store. That's right, and that's by design.

  Each virtual machine under ESXI is 'independent' (http://www.vmware.com/virtualization/virtual-machine.html)

  This means that each virtual computer must have its own copy of the application.

  This perspective reflection of each virtual machine as a separate system of 'physical '. They interact with each other as if they were physical systems.

  Each VMDK resembles a physical hard disk. Being accessible (in most configurations) 1 VM at a time.

  So if you had a set of physical systems connected to a domain and I wanted to install an application on each one, then each would have its own local copy of the application. It's the same thing with virtual machines.

  However

  If you configure a set of physical machines so that you run the software from a network share. It is possible to do the same thing using virtual machines using the exactly the same configuration. However, the chiefs more associated to this are important in both cases.

• best way to write this query

  Hello
  
  I have a problem and I realized a simplified version of it:
  
  

   
  
  create table deals (id_prsn number, id_deal number, fragment number); 
  create table deal_values (id_prsn number, id_deal number, value_ number, date_ date); 
  
  insert into deals values(1,1,50); 
  insert into deals values(2,2,40); 
  insert into deals values(1,3,50); 
  insert into deals values(2,4,80); 
  insert into deals values(1,5,20); 
  insert into deals values(2,6,80); 
  
  insert into deal_values values(1,1,10 ,sysdate - 3); 
  insert into deal_values values(2,2,208, sysdate - 3); 
  insert into deal_values values(2,4,984, sysdate - 3); 
  insert into deal_values values(1,null,134,sysdate - 3); 
  insert into deal_values values(1,1,13, sysdate - 2); 
  insert into deal_values values(2,2,118, sysdate - 2); 
  insert into deal_values values(2,4,776, sysdate - 1); 
  insert into deal_values values(1,null,205,sysdate - 1); 
  insert into deal_values values(2,null,-5,sysdate - 1); 

  The id of the requirement to join these two tables based on:
  
  1.) ID_PRSN and ID_DEAL
  2.) max DATE_ grouped per person and deal
  (3.) in the case that ID_DEAL is defined in the AGREEMENTS, but not defined in the DEAL_VALUES table, I have to join this records to DEAL_VALUES based on the person where id_Deal is null.
  
  Number 3 gives me headache. I realized the following query:
  

   
  
  select *from ( 
  select a.id_prsn, 
         a.id_deal, 
         a.fragment, 
         b.value_, 
         b.date_, 
         max(b.date_) over (partition by b.id_prsn, b.id_deal) max_date 
    from deals a 
  inner join deal_values b 
      on a.id_deal = b.id_deal or b.id_deal is null 
     and not exists  (select 1 from deal_values 
                                where id_prsn = a.id_prsn 
                                  and id_deal = a.id_deal) 
     and a.id_prsn = b.id_prsn 
  ) 
  where date_ = max_Date; 

  It returns the correct result of he,
  
  
  ID_PRSN ID_DEAL FRAGMENT VALUE_ DATE_ MAX_DATE
  1 1 50 13 16.10.2012 09:59:48 16.10.2012 09:59:48
  1 3 50 205 17.10.2012 09:59:48 17.10.2012 09:59:48 OK
  1 5 20 205 17.10.2012 09:59:48 17.10.2012 09:59:48 OK
  2 2 40 118 16.10.2012 09:59:48 16.10.2012 09:59:48
  2 4 80 776 17.10.2012 09:59:48 17.10.2012 09:59:48
  2 6 80-5 17.10.2012 09:59:48 17.10.2012 09:59:48 OK
  
  
  
  but the join clause:
  

   
  
  
      on a.id_deal = b.id_deal or b.id_deal is null 
     and not exists  (select 1 from deal_values 
                                where id_prsn = a.id_prsn 
                                  and id_deal = a.id_deal) 
     and a.id_prsn = b.id_prsn 

  in fact the query much slower.
  
  I was wondering is there a different way to write this join and manage the logic.
  
  Thanks in advance

  Here's a different approach:

  select * from (
    select a.id_prsn, a.id_deal, a.fragment, B.value_, b.date_,
    ROW_NUMBER() over(
      partition by a.ID_PRSN, a.ID_DEAL
      order by B.ID_DEAL nulls last, B.DATE_ desc
    ) RN
    from DEALS a
    join DEAL_VALUES B
    on a.ID_PRSN = B.ID_PRSN and a.ID_DEAL = NVL(B.ID_DEAL, a.ID_DEAL)
  )
  where rn = 1
  order by 1, 2;
  

  "nulls last" is the default sort order; I just put that for clarity.

• Is an array, the best solution for this problem?

  Hello
  
  I work a demo where a couple of small games come in a Panel. There is a main menu which you bounce around to select the things (games as well as other applications.)
  
  When one party runs, it takes up the entire jury. When two or more run, they run in a format "mini." In addition, when a game is running, a special 'return to the game' button in the main menu.
  
  It is a click by dog and pony, see the demo. It is not a production application, but it should work well enough to be played with internal clients. So it must work well.
  
  At this moment I have a few variables put in place as follows:
  
  var gameActive:Boolean = false;
  var gameDual:Boolean = false;
  
  In the launch menu and my game function, I check these (and one or two others) variables to see if I should do things like show a mini-version of the game or show return to the play button. I added many features, it becomes a bit difficult to handle.
  
  At stake is the games. Let's say that I only have two. I could make a table and then load in the name of the game, when a game is started. I could check this table in my functions to see not only if the games is launched, but the game is launched so I can use the full or mini games as the case may be.
  
  Is this a good approach, or is there a better way? I'm rusty with my code and not super comfortable, making things right now. But I could go on like this if it was the best.

  There's not much to it.  This is the only 3 things that you are likely to need to do with your associative array:

  var yourAA:Object = {};

  function addAAItem (aa:Object, o: DisplayObject) {}

  AA [o.Name] = o;

  }

  function removeAAItem (aa:Object, {o: DisplayObject}

  AA [o.Name] = null;

  }

  function aaLength(aa:Object):int {}

  var i: int = 0;

  for (var s:String in aa) {}

  i ++ ;

  }

  Return i;

  }
