different amount of resources and different prices.

Once the database has reached the maximum number of active connections, it will no longer accept new connections.

First, inconsistencies may arise in the new FM which has to be checked prior to be used as the DSPL architectural FM

DSPL designers should decide what degree of automation they need in order to support the runtime concerns of the DSPL in

There are potentially many types of decentralized control patterns, two of which are described, ring and serial patterns

queue up : faire la queue

it is going quiescent.

A  remove  command  is  used  to  remove  each component  that  will  no  longer be part  of  the  new configuration.


Import VM Argument into java application

In another tutorial, we saw how we could use the Locale.setDefault() method to set the default locale at runtime. If we examine the System properties, we can see the “user.language” property which is responsible for the default language and the “” property which is responsible for the default country. My “user.language” is set to “en” and “” is set to “US”.

Since the default country and default language for the locale are System properties, they can be set at start-up via -D VM arguments, such as the following arguments that set the default language to Swedish and the default country to Sweden.


In EclipseSW, we can specify the VM arguments in the “VM Arguments” textbox on the Arguments tab of our application’s Debug configuration:

Specifying VM Arguments in project's Debug Configuration

It should be noted that the “user.language” and “” values need to be passed as VM Arguments at startup and NOT set using System.setProperty() at runtime, since System.setProperty() will not influence the default locale that is already in memory. If you need to change the default locale during runtime, use Locale.setDefault();

		System.setProperty("user.language", "sv");
		System.setProperty("", "SE");

Các bước cài đặt VPN không cần IP tĩnh trên đường ADSL

1. Hoạch định và lựa chọn thiết bị: 

IP VPN có thể là phần cứng hay phần mềm, gồm VPN Server và VPN Client:

  • Phần mềm: hầu hết mọi hệ điều hành đều hỗ trợ. VD: đối với HĐH Windows thì hệ điều hành Win2K, Win2K3 Server có thể làm VPN Server vừa làm VPN Client, HĐH WinXP có thể làm VPN Client
  • Phần cứng: ADSL Router Vigor 2700 hỗ trợ 2 kênh VPN, Vigor 2800 series làm VPN Server lẫn Client (32 kênh đồng thời)… Tương thích với tất cả các thiết bị khác hỗ trợ IP VPN như CISCO, Fortigate, Check Point, Nokia và các hệ điều hành.

Le système adaptatif

  1. Des définitions

Le logiciel adaptatif – c’est le logiciel qui peut se changer son comportement pendant son exécution. Il a un certain nombre d’avantages potentiels,  la capacité pour réagir rapidement des menaces de la sécurité pour optimiser les performances comme les caractéristiques de l’environnement d’exécution sous-jacent changent.
