own synchronization to prevent simultaneous access from multiple threads from Causing a race condition. Calls to the MTA object from a thread in an STA is also marshalled. Dynamically determined Apartment (threadingmodel=Both) In the Both apartment mode, the server auto-selects STA or MTA at object creation to match the apartment type of The calling thread. This can is useful to avoid ma

less system resources. Like other MTA, Postfix has a primary configuration file. Each configuration of the postfix is table-driven and can be converted to any relational database or text file. It also uses a Perl-compatible regular expression library. Installing postfix is relatively complex compared to other MTA. It supports virtual mailboxes and virtual domains. Sendmail: in Linux

multithreading in ArcGIS Engine. This means that all Ao items should be put in one thread to work, and ao com components cannot be used across threads. Okay, I'm speechless, and there's no solution to this problem .. I really don't understand why it is limited to a thread. As in the last article, leave a message: Well written. I recently encountered the problem of multithreading in the Development of AE, which has not been solved. Finally, give up and return to the single-thread developm

This memory structure will have one for each thread. A COM object that supports STA can only be used in the line thread that created it, and other threads will fail if it is created again.Mta:mutil-thread Apartment, Chinese call

Project Background: the ratio of reading to writing is about. the number of users is more than one million, and the concurrency is about 4000 (high or low, high to 10 K, and low to 1 K) the performance of several servers is almost the same, and load balancing can basically be evenly distributed to each server. I want them to directly one to one through load balancing... project background: The ratio of reading to writing is about. the number of users

What is the difference between a Web server, an application server, and an HTTP server? What kind of server does IIS, Apache, Tomcat, Weblogic, and WebSphere belong to? This concept is important.The basic function of Web server is to provide Web information browsing service. It only supports HTTP protocols, HTML document formats, and URLs. Mates with the client's browser. Because the Web server primarily supports protocols that are HTTP, HTTP servers

Web servers and ApplicationsProgramWhat are the differences between servers and HTTP servers? Which server does IIS, Apache, tomcat, WebLogic, and WebSphere belong to? these problems have been confusing for a long time. Today, we have finally sorted them out: The basic function of a Web server is to provide web information browsing services. It only supports th

In web development, you often hear Web servers (Web server), Web containers (Web Container), application servers (application server), reverse proxy servers (Reverse proxies) Server) can be confusing and difficult to understand nouns. In the interview, this is also often asked. This paper introduces the understanding, difference and connection of the four people.

Web ServerWeb servers are generally divided into two types: Dynamic and Static. Static web pages are usually stored on servers by combining texts and images. They usually do not change much. Using two CPUs and One gigabit Nic can easily meet extremely high click rates. When a server uses a dual-processor, it can fully meet the requirements of thousands of clicks per second. It can also be used for large-sca

In the process of learning the front end. Process to hear and see the Web server, HTTP server, application server, but always do not know what the difference between them, puzzled for a long time, today, many of the blog read, finally sort of comb through, I will summarize their differences, shun do not know some servers.First we need to know that the Web server only supports HTTP protocols, HTML document formats, and URLs. The main function is to transfer the page so that the browser can browse

the Red Flag Linux system is released when it is announced to be compatible with the RPM package, and in the red flag provided by the tool CD, I see a lot of packages are Rhel 4, so you can determine, Red Flag Linux can at least support the RPM package in Rhel 4. If you're using an RPM package, it's easy to install, and it's annoying that servers and client and other libraries are packaged separately and downloaded. And I downloaded a single compres
