Bkjia.com exclusive Article]Oracle 11gR1 provides the ability to capture application loads in the production environment and replay loads in the testing environment, this technology is used to determine the impact on the performance of the system, database, or application after modification. In this article, I will describe how to capture and prepare the load from the current production database in the p + 0 environment, and how to

A BackgroundLast year, a MySQL trace replay test, due to the performance schema itself to collect sample length and other limitations, the actual playback of the success rate is relatively low.Recently found an open source tool, based on tcpcopy implementation of online traffic simulation test, this open source tool is NetEase's Wang bin development, many of the company's simulation on-line test is based on tcpcopy implementation.Https://github.com/se

Generation Log: All client and server interaction protocols will be placed in this log, and Vugen will then analyze the protocol interaction and eventually generate the script. The recorded Vugen script is generated from this log. If you want to return to the original state after an error or error modification at the end of the recording, you can use the Tools>regenerate script feature to regenerate the scripts back to the original state. recording Log: You can view related recording infor

Recently in the CSS animation, encountered the need to use a script to replay the animation. For example: CSS Animation code Copy Code code as follows: . seed_txt_out. seed_txt H2 { ANIMATION-NAME:SEED-H2; Animation-duration:2s; Animation-timing-function:ease; animation-delay:0s; Animation-iteration-count:1; Animation-direction:alternate; animation-play-state:running; position:relative; top:10px; } @keyframes SEE

If a client makes a request to a server-side interface, and if the request information is encrypted and intercepted by a third party to the request package, the third party cannot decrypt the data obtained, but the request package can be used for repeated request operations. If the server does not perform replay attacks, it will be the result of increased pressure on the servers and data disruption. The time stamp is used to resolve this problem.

7.3. replay attacks Replay attacks are sometimes called demonstration attacks. An attacker can reproduce the data sent by a valid user to the server to obtain access or other permissions assigned to the user. Like password sniffing, preventing replay attacks also requires you to be aware of data exposure. To prevent repla
