varchar length of 200, and the field of most of the existing data length of the row is basically 180 bytes, then the table Imports UTF8 encoded database, The field originally stored in most of the 180-byte Chinese characters, you need to 180*3/2=270 bytes of character length to normal storage, and at this time when performing the IMPDP import operation, the table structure will not change, that is, the original field definition colum001 length or mai

Colleague phone query Linux next cluster 2 hosts before and after 2 days of no response, the performance status of Ping did not respond.Because there is no monitoring or other performance data, you need to get historical OS performance data.We know that rhel5,6 can see the OS history information by default with the SAR command, so the SAR can see the data of the day.[[email protected] sa]# SARLinux 2.6.32-4

The goal of the second class is to create a simple online data management system with a movable lattice.Look at the design interface. Just started to follow the point, a little Meng circle, to finish, recalled, in fact, is to build a table, and then, the table and the page, that is, in the page to underline some areas, and the table field binding. Then generate the page as a tabular form.This is what happens after the build:This means that if I want t

After more than 10 years of development, China has made remarkable achievements in the construction and development of high-speed railway, and now has the world's largest and highest-speed high speed railway network. From the earliest 100 kilometers per hour "Dongfeng" diesel locomotives to the latest top speed of 486 kilometers of "harmony" high-speed car, China's railway technology to achieve a rapid leap-forward development, local technology has been in the forefront of the world.Similarly, i

of this.This is different from the previously mentioned "heap Files and indexes (' Heap file index ') approach, and it's a good idea to ask yourself," What's the difference between such columns and how each field has indexed "heap and index"?The key to the problem is the index file sequence: The Multipath lookup tree (Btree) is sorted according to the retrieved field, and the data connection at the end of the two retrieval involves a flow operation,
