stability and predictability, percona Server has an adaptive checkpoint algorithm. Percona also said that the version of Percona Server/XtraDB based on the MySQL 5.5 code baseline will be released. Currently, version 5.5.7 has been released, but it is still in Beta testing status and can be downloaded from LaunchPad.
The platform for Percona testing is a DELL PowerEdge R900 machine that uses a RAID 10 disk array and has about 50 GB of test data. conf

persistent connection often does not send data, so it can also be viewed as an inactive connection.For the system, this kind of inactive connection does not occupy CPU and network resources, but only occupies the system memory.Therefore, we assume that the system can support the number of connections we want as long as the system memory is sufficient. Is that true? If this is the case, it is also a test for the kernel to maintain this large data structure.

So, we assume that as long as the system has enough memory, the system will be able to support the number of connections we want to reach, so is the fact true? If this is the case, the kernel will be a test for maintaining this fairly large data structure. To complete the test, we need to have a server and a large number of clients. Therefore, the servic

Principle of RAID5 Data recovery algorithmTo understand the principle of RAID5 data recovery first to know RAID5, "distributed parity of the independent disk structure" is what we call the RAID5 data recovery has a concept to understand, that is, "parity check." We can simply understand it as an "XOR operation" in binary operations, usually using an XOR identity. The rule for this operation is that if the values are the same, the result is 0, and if the results are different, the result is 1.For
Method
Find Symcjit.dll, find two places, both JRE (Java Runtime Environment)
Rename the two files to Symcjit_.dll and install them, which can be completely normal.
Install hardware (already installed properly):

Description
A few days ago under the Win2000 installed two years ago, Oracle 8.1.7 ntee Release 1 (Enterprise Edition), found that after running the setup file, th

environmental or special application needs, equipment manufacturers strive for high temperature environment, the introduction of high-temperature-resistant servers or with cooling technology equipment for the overall solution, such as Dell PowerEdge Server can be 5 ℃ to 45 ℃ normal operation.
Dell to ensure that the enterprise data center servers, storage and other equipment in the high temperature environment to operate normally, reduce the additio
system prompts for insufficient disk space.
Third, find the reason:
There are a very large number of small byte cache files in the/data/cache directory, and the block is not much occupied, but it takes up a lot of inode.
Iv. Solutions:
1, delete some files in the/data/cache directory, release part of the/data partition Inode.
2, the Newcache directory in the free partition/opt is connected to/data/cache with soft connection, and the inode of/OPT partition is used to alleviate the problem
Server: dell™poweredge™860
System: Windows 2003 R2
Problem: Install the 2003R2 version, the BIOS can identify 4G memory, after installing the system, can only recognize 256MB memory.
"How to solve the problem"
Enter BIOS as shown:
Setting the original OS Install Mode = "on" to "off" solves the problem that the
DELL server does not recognize 4G memory .

supported multiple cores, including the operating system and all of Microsoft's applications, other leading American software vendors have already achieved most of the multithreading of their software. As for the Chinese and Asian markets, there has been great progress in implementing multi-threaded applications, so the main obstacle to software has been overcome. This year, Intel will be integrated into the dual-core products, by the end of this year, 85% of the server will achieve dual-core.
