Display is almost every computer player to face every day, its work "performance" of good or bad, not only affect our day-to-day office efficiency, but also with our eyes "feeling" closely related. Let the monitor work daily, let it work "performance" has been in a good state, this is the tireless pursuit of every computer player; however, the display in the long time for our "service" process, there will inevitably be a variety of unexpected illnesse
Label:The pain and suffering of SQL analysis Many DBAs have some questions about the SQL statements on the line, and it's good to look at the cost of executing the plan, but there's a big difference in the actual execution. For a large SQL statement, looking at the resulting execution plan without knowing where the bottleneck is, the SQL statement is too complex, the execution plan looks more complex, and it is not easy to read the essentials. Occasionally some friends ask me, how to read an i
For normal testing, you often need to look at the data in Performance Monitor and now teach you how to turn on Performance Monitor:
1. Start-run (or press Win+r to open the Run dialog box)
2, input "Perfmon", and then enter

This is the article published today by MSDN on Windows 8 and multi-monitor support, and the author, Steven Sinofsky, reads: When people use a computer that connects multiple monitors, the satisfaction of the experience increases. A multi-monitor operating mode allows us to perform multiple tasks at the same time, thereby increasing the user's productivity. Windows 8 will lead you to experience the benefits
From: http://www.cnblogs.com/freshman0216/archive/2008/07/29/1252253.htmlThis article starts with the class relationship diagram of monitor, mutex, manualresetevent, autoresetevent, and waithandler. We hope to have a general understanding of common thread synchronization methods through this introduction, the application details of each method are not explained too much. Let's take a look at the relationships between these classes:

Abstract: This article introduces that the C # monitor class can lock an object. A thread can operate on this object only when this lock is obtained. The object lock mechanism ensures that only one thread can access this object at a time point that may cause confusion. When multiple threads share an objectCodeFor a similar problem, the lock keyword should not be used. here we need to use a class monitor
solely on the show slave status provided by MySQL itself. Pt-heartbeat is a good choice for master-slave replication latency monitoring. This article describes the latency monitoring in the case of master-slave replication and provides corresponding examples.
Pt-heartbeat is one of the percona-toolkit. Therefore, you need to install percona-toolkit before use. For details, see percona-toolkit installation and introduction.

Said to be incompatible, the actual fault is not a true sense of incompatibility, only from the symptoms of failure and language expression on the use of the word "incompatible" is more appropriate. This failure is not uncommon, with the computer more and more time to use, monitors and mainframe components are also slowly aging, capacitance capacity in the slowly become less, resistance will have some changes, then there may be some inexplicable fault, to our maintenance bring great trouble.Here
