• reading non-blocking

  Hello

  I'm trying to implement a lock read along the lines of peekdata() in matlab http://www.mathworks.de/access/helpdesk/help/toolbox/daq/index.html?/access/helpdesk/help/toolbox/da...

  I found I can do readings not blocked from using the reading + http://forums.ni.com/ni/board/message?board.id=230&thread.id=2862 reminders

  Is there another way to get non-blocking reads?   The reason is that if the above, I've implemented the matlab Matlab mex interface calls the file (mex) C and I do read (must wait the trigger occurs) before returning from the C file (aka it becomes again blocking). So that callbacks are not really useful if the thought in a single thread passing that matlab works.

  Thanks for reading.

  The way in which the driver is written is to block on a reading DAQmx.  In a single threaded method will always call blocking as I know.

• TTIMDB connection problems: cannot resolve a non optional application descriptor property [DSN]

  Hello

  We currently have the plugin TTIMDB 11 g deployed in our instance of EM10g without a problem and you want to migrate to 12 c.  Us have deployed/installed the 12.1.0.2.0 plugin in our instance of EM12c and it deployed to the agent of the 12cR3 on our dev TTIMDB server.

  When you add the target TTIMDB in the same way that it is deployed in 10g, fine tested connecting to the DB, however the target shows down with the following errors...

  1. supervised > all measures, we get this... "The TimesTen database is declining: [name of the source/db data] is not loaded '

  2. under the target Configuration > Monithat test us the connection and if Configuration connection test when fTSRI Configure the plugin has worked it is now failing... "
  Response; Cannot resolve a non optional application descriptor property [DSN] (DSN).

  
  

  Any thoughts on what may cause these errors?

  
  

  Thank you

  Hi Steve,.

  We are talking about the same thing. When I check to see if the TimesTen database is loaded into memory, I mean make sure that the database is running.

  By default, a TimesTen database is loaded into memory (start) during the first connection to the database. When the last connection to database stops, it will automatically unload the database of memory (close).

  As it is recommended to change this database startup behavior by manually changing the setting of strategy of the RAM .

  That is right I've proposed a ttIsql to connect to the database during the EM test. This will ensure that the target database is in place and running, so EM can connect to it.

  If you can stay connected to the database target using ttIsql and EM reports again that the database is down, then Yes, there is another problem.

  I suggest recreating the target and try again.

• Non-blocking with Perl VI API monitor task

  I am writing a perl script that needs...

  1. Suspend a virtual machine
  2. Do 'some other supervision' while the virtual machine in the suspension process
  3. Make sure that the task is complete suspension

  I was looking at the documentation for the API, but also the code example and there are many examples which have helped me understand how to do #1 and to some extent #3 by calling SuspendVM() on the managed virtual computer object (see my sample code "Option 1").  But it is not perfect for #3 and does not allow me to do #2 at all.  API documentation leads me to believe that I should be able to use SuspendVM_Task() on the virtual computer object for a task monitor-a measure of object (see 'Option 2') in my sample code.)

  However, I can't understand how to use this object task to track progress.  I think it must be something like "Block monitor" in my code, but that doesn't seem to work.  Watching a dump of the task object, "info" property seems to not even be there.  I can bless the object to its class real slot (instead of the generic ManagedObjectReference, it starts as), but then the property of the info is just empty.

  I know I probably stopped next to a simple shade of perlOO/perl/perlReference, but can not find where I'm going wrong... any help out there?

  Output of dump of the object of the task

  ========================

  $VAR1 = bless ({}
  'value' = > ' haTask-1808 - vim.VirtualMachine.suspend - 1852795401',
  'type' = > 'task '.
  (}, "ManagedObjectReference");

  Code example

  ==========

  #! / usr/bin/perl - w

  use strict;

  use warnings;

  Use Data::Dumper;

  use VMware::VIRuntime;

  past #./vmSuspend.pl--mot, username - XXXX XXXX - Server XXX.XXX.XXX. XXX - vmname XXXX

  My % opts =)

  'vmname' = > {}

  Type = > "s =",

  help = > "the name of the virtual machine.

  required = > 1,

  },

  'filter' = > {}

  Type = > "s =",

  help = > 'filter to select corresponding virtual machines. "

  required = > 0,

  },

  );

  OPTS::add_options (%OPTS);

  OPTS::parse();

  OPTS::Validate();

  Util::Connect();

  My $retval = 0;

  my $name = Opts::get_option ('vmname');

  My $vm_view = Vim::find_entity_view (view_type = > 'VirtualMachine',)

  filter = > {'name' = > $name});

  my $state = $vm_view-> run - > powerState-> val;

  Print "$name is $state\n";

  # Option 1 - blocking

  # $vm_view-> SuspendVM();

  # Option 2 - non-blocking

  My $suspendTask = $vm_view-> SuspendVM_Task();

  print Dumper ($suspendTask);

  # Block monitor

  # everything in ($suspendTask-> info-> status-> val eq 'running' | $suspendTask-> info-> status-> val eq 'pending') {}

  # < < some other surveillance > >

  #}

  $vm_view-> update_view_data();

  $state = $vm_view-> run - > powerState-> val;

  Print "$name is $state\n";

  Take a look at this script for example: http://communities.vmware.com/docs/DOC-10269 there is a method in there called getStatus() that shows you a task queue is complete before continuing. You are on the right track, but must do a few more things to get the display of the task and make sure that you update the view after sleep/wait and then check again.

• Application Modules Resuablity face-to-face Web and Non Web Application

  I have a web application that uses the plsql API list and not of Java Web Application that uses the same API plsql can I write an Application Module and use it in the web not Application?
  
  If not
  If there is a way to manage for the Non Web Applications connection pooling
  How can I share common codes that plsql api call between Web and Non Web application
  
  IF yes how can I manage the DBTransaction creation for non web?

  Hello

  You can use application Modules in non-web environments.

• How to use a KeyManager custom in SSLSocketChannel non-blocking

  In our existing project I had to replace the SocketChannel non-blocking by SSLSocketChannel no blocking. My implementation of the SSLSocketChannel non-blocking mask all the SSL stuff and can be used as a SocketChannel overall of the project that just use the SSLSocketChannelProvider instead of SocketChannelProvider in one place.
  
  Now I have a new requirement. Different server-certificate should be used for various IPS on the same SSLServerSocket. The relationship between the IPs and certificates is well known. The first idea was to use a custom KeyManagerDelegate that extends from X509ExtendedKeyManager to select the certificate from the server. The KeyManagerDelegate should delegate calls to a KeyManager obtained by

  KeyManagerFactory.getInstance("NewSunX509").getKeyManagers();

  It works if I use a blocking SSLServerSocket obtained by SSLContext.getServerSocketFactory () .createServerSocket ();
  
  But the KeyManagerDelegate is never called by the SSLContext if I use my own non blocking SSLServerSocketChannel. Instead of calling my KeyManagerDelegate the SSLEngineImpl throws an Exception
  

  javax.net.ssl.SSLHandshakeException: no cipher suites in common
       at com.sun.net.ssl.internal.ssl.Handshaker.checkThrown(Handshaker.java:951)
       at com.sun.net.ssl.internal.ssl.SSLEngineImpl.checkTaskThrown(SSLEngineImpl.java:466)
       at com.sun.net.ssl.internal.ssl.SSLEngineImpl.writeAppRecord(SSLEngineImpl.java:1092)
       at com.sun.net.ssl.internal.ssl.SSLEngineImpl.wrap(SSLEngineImpl.java:1064)
       at javax.net.ssl.SSLEngine.wrap(SSLEngine.java:452) 

  The next thing I'm going to try would be to get the SSLContext to use my own SSLSocketChannelProvider as ServerSocketFactory.
  
  Or I use different SSLContext for each incoming connection, which would break my own design because the server had to waste his time with the construction of new SSLContext. Another possibility is to implement a callback in the ServerSocketChannel to get a new SSLContext for each accepted connection. It would be sure my design but looks like a ugly workaround solution for me and I do not know if it works.
  
  All the best ideas?
  
  Thanks Domi

  I just tested this with my SSLSocketChannel and it works like correctly, the KeyManager methods called as expected. You hurt something else ;-) Do not extend X509ExtendedKeyManager to work properly with the engine.

• Web HTTP proxy using IO Non blocking

  Solved thank you...

  customer. Register (selector, SelectionKey.OP_READ
  | SelectionKey.OP_WRITE);

  OP_READ only at this stage. OP_WRITE is always 'ready' unless the socket buffer is full, so your selector will turn only. Do not save OP_WRITE until you have something to write.

  ByteBuffer bferClient = ByteBuffer.allocate (4096);

  You do this each time around the loop, and you don't even know if the key is still readable. Do it when you accept a connection, and then save it as the essential accessory for this channel.

  client.configureBlocking (false);

  It is already in non-blocking mode. Why you do it again?

  try {}
  If ((bytesRead = client.read (bferClient))! = - 1) {}

  bferClient.flip ();
  String msgFromClient = new String (bferClient.array ());

  new String (bferClient.array (), 0, bferClient.limit () - 1), but you're assuming that you've got a complete command here. You do not have. This is another reason why you need a ByteBuffer by channel.

  Channel.Connect (SocketAddress);

  You should do it in non-blocking mode, save the channel for OP_CONNECT and leave the select loop to take care to complete the connection.

  Channel.Write (bferClient);

  The incoming command is CONNECT. You do not write than upstream.

  If (!) » ». {Equals (msgFromClient.Trim ()))}
  int bytesReadServer;
  response from Byte [] = new ubyte [4096];
  try {}
  ByteBuffer bufferNIO = ByteBuffer.allocateDirect (1024);
  While ((channel.read (bufferNIO))! = - 1) {}
  bufferNIO.flip ();
  customer. Write (bufferNIO);
  bufferNIO.clear ();
  }

  And you don't do that here. Register the new channel for OP_CONNECT, then when you get finishConnect() and then save it to OP_READ, and moving forward in your select loop. You also need to associate the channel with the channel that read you the CONNECTION since. If you really need an object of attachment key for the original channel that contains the buffer of bytes and the channel upstream; Similarly, the channel upstream must a key attachment that contains sound buffer and its channel downstream. The effect of making all this stuff here rather than around the loop of selection is that you're never going back to the loop of the selection: you manage what a customer here in blocking mode, until the connection is dropped. Completely wrong.

  } catch (IOException e) {}

  Hang up. If bytesRead a-1, you must close the channel.

  e.printStackTrace ();

  And if you get an IOException here you must also close the channel.

  If (channel! = null) {}
  try {}
  Channel.Close ();

  This is a really strange place to close this channel.

  When you get this fixed upward, your zip code and I will tell you how to handle the OP_WRITE.

• Modal dialog box non-blocking

  Hello world
  
  I want to display a modal dialog box, capture user input and use it for further processing, as below:
  
  showWindow(); PopupManager.createPopUp () calls
  code to deal with user input
  
  My problem is that the showWindow() call is non-blocking, i.e. the code to deal with user input is executed immediately after the posting of the modal window. How can I do to run when the modal window is closed?
  
  Any help will be greatly appreciated.
  
  Thank you
  
  Rajesh Jayaprakash
  

  You can register a listener for the event of closure of the pop-up window and then on this listener, call the method that you want to run when the window is closed.

• UTL_TCP (mode of blocking or non-blocking sockets)

  Hi all,
  
  Please, does anyone know if the UTL_TCP using blocking or non-blocking mode sockets? I did a search but cannot find this information.
  
  Kind regards

  UTL_TCP.open_connection has a parameter of tx_timeout. If set to 0, the connection is not blocking. A value of n will trigger the connection block for n seconds before exhaling. Null value causes the connection to block indefinitely.

• record of /Hybrid/ with non-hybrid applications

  Hi guys,.

  Just trying to figure why I have animals associated with non-hybrides apps in

  .../user_projects/epmsystem1/EssbaseServer/essbaseserver1/hybrid/ < appname >.

  In fact I don't have hybrid any application on this server.

  Thank you

  I thought that the hybrid file is filled in when any cube BSO is launched and it does not matter if the hybrid parameters are applied.

  See you soon

  Updated with the reference of the documentation:

  Clarification: Additional directories are created for the aggregation of the hybrid, although the hybrid aggregation is not enabled

  In the Readme Essbase 11.1.2.3.500 file, the following information describes the additional directories created in the application for the aggregation of the hybrid. Please note that these directories are created even if the hybrid aggregation is not enabled.

  Associated with the addition of hybrid aggregation in block storage bases, in this version, the following subdirectories are created under $ARBORPATH/hybrid/AppName:

• Blocked application

  I have a web site (www.paphosinfo.com), which has a visitor counter. This has worked for many years but recently has forced me to say that I want to run the application "unsecured".

• Download touch and non-touch application with the same name

  HII I'm doing a new version of an application

  in the new version of the application, I have two separate release touch and non touch.

  so create us the same name of the app and app-world as a separate product with a different version

  and download sound on 22 Dec 2012 but until the pending status

  so exactly what I do if blackberry approvue my request

  When I send an email to app world support rereading as 'is there a reason? why you create the same application again  You can't have two applications in the portal of the same name. »

  Thanks again in advance for proofreading

  I would look to create the same application in charge touch and non touch at the same time.  You can do if your application supports OS 4.7 and later only.

  If you really need to do two different builds, then add the two builds in separate bundles to the same app on App World and use the selection of the device to make sure that your touchscreen package is only for touch devices to screen and vice versa.
