Case Study of excessive time in slow query logs
Description:
Recently, when analyzing the server's slow-log and bin-log, we found that these two logs contain some statements.Execute time is extremely largeFor example, 4294967295.Log information: #091008 21:40:04 server id 1 end_log_pos 3440531 Query thread_id = 63169 exec_time = 4294967295 error_code = 0However, the statements with a very long execution
Classic case study of MAC address drift
The network topology is as follows:
IRF virtualization is performed between the two carrier access switches (that is, two switches are virtualized into one), and VRRP hot backup is performed between the two Server Load balancer instances.
The network structure is Layer 2, and the gateways of each link are located at the carrier.

I. Based on the 7 UX evaluation criteria We have listed, we analyze the "public number of educational management system of Nantong University" where you feel satisfied with the user experience design (not less than 2 o'clock) and (20 points), please state your reasons.A: 1 give users timely and quick feedback. Whenever there is a need, the system can give a reply immediately, without taking the time to wait.2 User control rights. Users can choose the relevant information for their own needs.Two.
Advantages:1. Necessary tips and help documentationThis public number is more convenient to use, the wrong or lost will automatically appear the public number of functions, very humane.2. Give users timely and quick feedbackUse this public number for results query, timetable query, public elective course inquiry, etc., the speed of feedback is very fast, almost no need to wait, compared to the use of computers more convenient and save time. 3. Academic Work ReminderThe public number wil
most important function one is the result inquiry, the other is the public elective course registration, does not register in the public elective course and checks the resultPeak, the public number is basically idle. While the public elective course registration, the system is very easy to paralysis. Some of the people who push attention are still very few,3. Query empty classrooms This function also has Other software can be implemented, such as many college students in the super timetable,
First, based on 7 UX evaluation criteria for the public number: Nantong University Educational Administration system of the public number analysis.1: The response to the user is particularly fast.2: The interface is very neat, instructions are very simple is the man's pinyin initials.3: The reply is accompanied by other requirements of the instruction abbreviation. Convenient for users to query.Secondly, there are still many problems in the public administration system of Nantong University, the
users timely and prompt feedback "
No "suggest" or "feedback" function at all
interface does not conform to Convention
Unlike most public interface, this public number is not a function menu , there is no keyword settings , the way users get the information they want only by the directory to enter specific characters, and historical messages are It's impossible to find it directly. This is more like a text messaging service, not very convenient.

performed based on the channel-zone server.3. Compile a statistical script and save the statistical results to the result library. A game has only one result Library (including all channels and servers)4. Because there is only one result library, you need to consider Table sharding to avoid slow Query when a single table is too large. The analysis is as follows:Assume that there are 50 channels, 100 regional servers, and no more than 5 single-Table dimensions. Estimate the [10 W-15 W]/day incre
