In the previous article, we realized the high availability of Exchange CAS servers, and today we look at the high availability of mailbox server MBX.Mailbox servers are used to store all users ' mailboxes, no doubt about the importance! The previous version of EXCHANGE2007 uses disaster-tolerant technologies such as LCR,CCR, while the more stable and up-to-date DAG technology is used in Exchange2010.What is

Article Title: Linux: build bridges between different servers. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Integrating Linux and Windows servers may not be easy, but it is indeed the best solution for enterprises. In the past few years, the Linux and Windows operatin

Recently and a few friends, chatting to concurrency and server stress issues. Many friends, do not know how to calculate concurrency?　How many servers are appropriate to deploy? So, let's talk about it today. PV and concurrency, as well as how to calculate the number of Web servers. These are their own ideas plus some online summary, if not, welcome to shoot bricks.Several conceptsWebsite traffic refers to

discarding the hardware, you should follow some of the advice and advice given below. Feasible disassembly and modification scheme Many companies have made the mistake of discarding the old server in a corner, which is bad behavior anyway. From a security point of view, the data is easily stolen, the server is easily stolen. Equally important, the value of the server has been lost over time, and the unused servers can be retrofitted to a new office,

When using a linked server (Linked Servers), the most expensive cost is the transmission of large amounts of data between network bandwidth. It is important to write the correct code on the correct server, because each error can cause a very expensive cost to the network bandwidth. Here are a few common errors when using a linked server (Linked Servers):1: Use push method instead of pull method to fetch num

file format is the same as the authz File above the article, editing the file passwd put in the folder/etc/httpd/conf. d, use the following command to generate the user name and password: Htpasswd-c/svn/project/first admin // The command is htpasswd,-c is the parameter,/svn/project/first is the accessed version library, and admin is the user name Then, repeat the password you want to set to automatically store it in the file passwd. The default value is md5. ⑤ Restart the apache servic

A server, one of the most important resources is memory, memory enough, is directly related to system performance is the key.This article describes how to view the memory usage of Linux servers.1.

If you have more than one memcached server side, it is best to use memcache::addserver () to connect the service Frontend. instead of Memcache::connect () to connect to the memcached server, the PHP client uses the server pool to assign keys to different servers based on the algorithm.

Net.ipv4.tcp_max_tw_buckets = 5000Indicates that the system maintains the maximum number of time_wait sockets at the same time, and if this number is exceeded, the time_wait socket is immediately cleared and a warning message is printed. The default is 180000, which changes to 5000.For Apache, Nginx and other servers, the parameters of the last few lines can be a good way to reduce the number of time_wait sockets, but for squid, the

Introduction to HTTP protocol Hypertext Transfer Protocol (HTTP) is located in the TCP/IP protocol application layer, is the most well-known protocol, but also one of the most core protocols in the interconnection network, the same, HTTP is based on C/s or B + + model implementation. In fact, the browsers we use, such as Netscape or IE, are the clients that implement the HTTP protocol, and some common Web server software such as Apache, IIS, and iplanet Web

smtp| Server in the forum to see a lot of Master's speech, combined with their experience in practice, and finally have some comparative molding experience: The first thing to say is that two virtual SMTP servers are essential to prevent spammers from using your Exchange server for transit and other illegal uses of your SMTP service. This seems to be a very basic conclusion, but it is my "blood and tears" of the word. Because I used to rely on a vir

application are still on different application servers. This is mainly to facilitate employees from outside the enterprise access to the OA system. The advantage is that when a Web service suffers an attack that is not available, most employees are unable to access the OA system from outside the enterprise, without affecting the normal access of employees within the enterprise. However, I have made a similar mistake before. At that time, the enterpr

access|server|sqlserver| Access | server | links | data | database In WEB development, you often use an Access database. However, because access is a file-type database, Access cannot be made across servers. Through the author's exploration, we find that we can use the linked server of SQL Server to integrate the geographically dispersed Access database, so that the Access database has the ability to cross the Web server farm. By doing so, you can als
