It's very simple-to-configure a IBM HTTP Server/apache service on a Server. But sometimes, considering the cost or any other reason, we need to share a physical server and configure 2 or more Web SE Rvices. How to do it?Here I lists the major steps for reference and for my own record. These articles would not be only c

By turning on Statistics io, we can understand the IO overhead of statement execution , including physical reads, logical reads, pre-reading, and so on.

Physical reads: After the query plan is generated, if the cache is missing the required data, let the cache read the hard disk a
For ms SQL Server databases, there are several problems that are easy to misunderstand. For these problems, even if many SQL Server DBAs have incorrect understanding or insufficient understanding, therefore, I want to write a few articles to elaborate on the problems that are easy to understand and make mistakes. I also hope to correct these questions on the Internet (or I may know something wrong, ).

Notes on Linux physical server migration
Two days ago, we performed online migration on the two servers in the production system. Therefore, we would like to summarize some of the operations and lessons learned before and after the migration. In a professional style, I have read some official migration guides from Microsoft and RedHat before and after that, but I found that there are not many practical sect

A guid is a hexadecimal number of 16 bytes. duplicate numbers are not displayed. Compared with the ID column, guid can ensure uniqueness in a larger range.
Guid advantage: you do not need to perform a comprehensive check when copying a database that uses the guid primary key. the randomness of the guid value can reduce the hotspot of the database. You can use multiple metho
