    I need help for the upgrade of my current system.

    I have SBS 2008 with (Exch 2007, SQL 2005, Sharepoint, backupexec 2010 for sbs) licenses.

    I want to make the larger environment using the following:

    (1) apply Virtualization

    (2) apply to the failover process (clustering)

    "(3) the environment must support adding server terminal server, ERP server, exchange server, domain controller, backup manager.

    Storage 4) that supports Raid (1 and 5)

    UTM excellent 6) that supports (SSL VPN, VPN Global)

    suitable backup solution 7)

    (8) good antivirus for clients

    my questions:

    (1) can you provide me with a good design for this environment

    (2) should I choose what operating system:

    Microsoft datacenter or company

    I know datacenter provide us the unlimited VM but needs per processor license

    so if I have two Grouped servers I want to buy 4 licenses

    and just 4 VMs per company license... to say that we have two servers and maintain 8 vms so wat happened if 1 goes down... How can I migrate the 4 virtual machines on the server failed to another server group... ? should I buy enterprise license?

    (3) if I get the SAN storage for data... How can I save this storage... should I get another SAN?

    (4) how can I upgrade SBS stad single server (windows standrad) without losing the licenses as Exch 2007, SQL 2005, sharepoint.is it a must to buy an edition full std server or there is a way to upgrade (license wise, I mean)?

    (5) what about win2k8 license for VM:

    lets say we have physical that has windows license so that enough to have windows for VM or should I buy windows for VM licenses?

    (6) can I use backExec license for SBS with windows 2008 standard

    (7) who better to virtualization AMD or INTEL

    (8) hyper V or VMware?

    (9) what of Microsoft data protection Manager... is this good?

    (10) what virtual machine manager? What are the benefites keys

    What are the requirements of system for this program?

    What version of Windows it says on the package, it was designed for?

    If its designed for an earlier version of Windows such as Windows 95 or Windows 98 or XP, then it is probably incompatible with Windows 8.

    If the product packaging indicates anything in the 1990s OR early 2000s, I am afraid that this is not something that is guaranteed to work with Windows 8.

    You can try the following average time.

    Point to the installation files where they are.

    Right-click on the configuration file, and then click "troubleshoot compatibility".

    Sorry, but the restriction password cannot be reset, it is part of the backup and restore a backup that was taken after the restrictions were activated, restore this code again.

    You will have to start without the help of the data backup, configure the phone to factory settings and start over. Follow the steps mentioned in this article:

    Use iTunes to restore your device to factory settings - Support Apple iOS

    If you lose or forget your password restriction, you must erase your device and then put it up as a new device to remove the restriction password. Restore the device by using a backup does not delete the access code.

  • 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!

  • Solution for the mutation of table of error when using triggers

    Hello

    Could you please give the solution for the error table mutation during the use of triggers. I'll give you the simple scenario here,

    I created a trigger on the employees table, whenever all DML operations takes place in the employees table, it must run the trigger body. I intentionally used also of the employees in the body of the trigger table. Please give me the solution.

    Triggering factor:

    create or replace trigger test_trigger

    before you insert or update or delete employees

    for each line

    declare

    an employees.first_name%type;

    Start

    Select first_name from people where job_id = "AD_PRES";

    end;

    DML statement:

    Update employees set salary = 20000 where job_id = "AD_PRES" (I run this query)

    Error message:

    ORA-04091: table HR. Is the transfer of EMPLOYEES, the function of triggering/can not see

    ORA-06512: at "HR. TEST_TRIGGER', line 4

    ORA-04088: error during execution of trigger ' HR. TEST_TRIGGER'

    Can anyone tell, in what other scenarios, we get this error or recursive table mutation?

    Thanks in advance

    Hello

    When you create a trigger on a table, you cannot edit/query this table the trigger is not completed.

    You can use

    (1) transaction of Pragma autonomous

    (2) instead of row-level trigger, you have statement-level trigger

    (3) to 11 g, try with COMPOSITE trigger

    Try below to avoid it (a solution):

    create or replace trigger test_trigger

    before you insert or update or delete employees

    for each line

    declare

    PRAGMA AUTONOMOUS_TRANSACTION;

    an employees.first_name%type;

    Start

    Select first_name from people where job_id = "AD_PRES";

    COMMIT;

    end;
