column read and write command must have an interval with the row valid command, this interval is defined as TRCD, that is, RAS to CAS delay (RAS to CAS latency), this is very well understood, After the address line to send the line address, to wait until the line address stable positioning and then send the address, TRCD is an important time parameter of SDRAM, the relevant values refer to the corresponding chip hardware manual. Usually trcd in the number of clock

compare the algorithms by the number of cycles.2. Exchange Law:The procedure for exchanging is the clearest and simplest, which is compared and exchanged each time with the following elements of the current element one by one. Copy Code code as follows: #include void Exchangesort (int* pdata,int Count) { int itemp; for (int i=0;i{ for (int j=i+1;j{ if (Pdata[j]{ itemp = PData; PData = Pdata[j]; PDATA[J] = itemp; } }

In the actual production, Tomcat server is generally not used alone in the project, the response to static resources Nginx performance is better, in addition, because Nginx is dedicated to reverse proxy server, it is easy to implement the Java request forwarded to the back end to the Tomcat container processing, And itself is used to handle static resources.Usually the Tomcat front end is Nginx or Apache, the back end is Tomcat, also means that no matter what the front-end is the role of the age

It takes about 40 s Unfortunately, CentOS uses the command method and can be tested without a browser. By default, JBoss only listens to localhost, so it can

requests that can be placed in the processing queue when all the threads that can be used to process the request are used, and requests that exceed this number will not be processedThis is an optimization of the HTTP connector, and if you use Apache and Tomcat to load balance the cluster and use the AJP protocol for Apache and Tomcat protocol forwarding, you also need to optimize the AJP connector.connecti

The integration of Tomcat and Apache has the following advantages: 1. Use Apache for load balancing and fault tolerance; 2. Apache focuses on static Web page parsing and tomcat focuses on dynamic web page parsing, which can improve server efficiency; 3. Applications can be upgraded seamlessly. First install Apache and Tomcat and install the mod_jk (SUDO apt-getinstall libapache2-mod-jk ). I. AJP Connector Tomcat 6 provides the

It was originally installed with APT-Get on Ubuntu apache2, but how can not be integrated with Tomcat 5, there are a lot of online Introduction, basically is the use of mod_jk-apache-2.2.4.so, through it to forward requests to Tomcat, according to the following post, I have fully configured it (because it won't compile, so I searched this post to directly compile the mod_jk version): Apache and tomcat integration, however, after running, apache2 does not distribute requests to Tomcat. Then, reco

Coyote package. connector is divided into the following categories: HTTP ctor Ctor is responsible for establishing HTTP connections based on the HTTP protocol. It can be divided into bio HTTP ctor AND NiO HTTP connector. The latter provides support for non-blocking Io and persistent connection comet. Based on the

Tomcat source code analysis (startup Framework) Preface: This article is some of my experiences after reading the Tomcat source code. It mainly explains the Tomcat System Framework and startup process. If you have any mistakes, please criticize them! Suggestion: After all, the Tomcat framework is still complicated. It is not easy to grasp the Tomcat framework simply by understanding the text. Therefore, you must practice, practice, and practice again. We recommend that you download the Tomca

Modify the port number when multiple tomcat servers are deployed on the same server. tomcat details When multiple tomcat servers are deployed on the same server, port numbers conflict. Therefore, you must modify the tomcat configuration file server. xml. Take tomcat 7 as an example. First, let's take a look at the main tomcat ports: 8080 is the HTTP port and 8443 is the HTTPS port. 8005 indicates the remote service Stop port 8009 is the AJP
