Chapter 2.. NET Resource ManagementChapter 2:. NET Resource Management
A simple fact:. Net ApplicationsProgramIt runs in a hosted environment. This environment has a lot of conflicts with different designers, so there is always Objective C #. To greatly discuss the benefits of this environment, you need to change your thoughts on the local environment to. Net C
4.2 Evictor Mode
The Evictor mode describes when and how to release resources to optimize resource management. This mode allows us to configure different policies to automatically determine which resources should be released and when they should be released.

Highly robust and scalable systems must efficiently manage resources. Over time, ApplicationsProgramIt will get a lot of resources,
The graduation design of the enterprise human resource management system greatly improves the utilization rate of enterprise talents and the convenience of personnel management, which creates greater value for enterprises. The improvement of talent utilization has enhanced the core competitiveness of enterprises, comprehensively improved the

In a perfect design, all resource access should be done through resource management objects, and resource leaks are perfectly overcome. However, the world is imperfect, and many APIs directly manipula
Resources are owned by the system and must be returned to the system after borrowing resources. The main resources include: memory, file descriptor, mutex, font in graphical interface, database connection, network socket. article : Managing Resources with Objects Memory that is managed by pointers in an object, such as memory allocated dynamically during a run , can easily be forgotten by the user, or it is difficult to grasp its release time, thus causing a memory leak, by using the object to
Resources are: once used, they must be returned to the system in the future. In addition to common memory, there are also file descriptors (File description), mutex locks, brushes in the graphic interface, and database connections.
And network socket. Considering exceptions, multiple return paths in functions, and software changes made by the program maintainer, the impact was not understood, and it was found that the special methods of resource

III. Resource Management The resource is that once you have used it, the system must be returned in the future. The most common resource in C + + is dynamic memory allocation. In fact, resources also include file descriptors, mutexes, glyphs in graphical interfaces, paint brushes, database connections, sockets, and so
Network resource Management
network resources refers to the use of network equipment through a variety of means of installation, deployment, maintenance of the form of information containers or channels. The main difference between it and network equipment is: network resources is a logical concept, network equipment is the physical concept of network resources is the processing and utilization of network

Using the features provided by cgroups, you can easily limit the physical memory usage of a group of services within the system. For network packets, device access, or IO reso
The configuration of resource limits (large list) in the SharePoint Management Center is the core of SharePoint. Everything in SharePoint is a list. It can be said that SharePoint content is list-driven. The disadvantage of SharePoint in earlier versions is that when more than 2000 items are listed, the performance will be degraded. This does not mean that if the list contains 2001 items, the performance de
Resource management has been a place where C + + is criticized by other languages, such as Java. It is undeniable that garbage collection is a more advanced and efficient means of managing resources, and because of its internal algorithm improvement, its speed and efficiency is gradually improved. But, after all, garbage collection allows programmers to take a step further away from the system, not only to
