1. Introduction of equipment Management
Devices in AIX are managed in a tiered fashion.
At the top is the functional classification, which is grouped by the same basic function, for example, all adapter cards belong to the adapter class.
The next level is a functional subclass, divided according to a clearer specific nature, such as a standard input/output adapter card and a Microchannel adapter, where the standard input/output adapter card belongs to the Sio functional subclass, and the Micr
Sometimes you need to collect various information about the server, such as CPU information, memory information, Linux version information, and various software information installed. The following describes how to view the main indicators. 1. view the Linux release information [root @ pcmweb ~] # Cat/etc/issue

Devices in AIX are managed hierarchically.
The top layer is the function category, that is, grouping by the same basic function. For example, all the adapter cards belong to the adapter class.
The next level is the function subclass, which is divided according to more specific properties, such as standard input/output adapter and micro channel adapter. Standard Input/Output adapter belongs to the class of the SiO2 function, the micro-channel adapter is a sub-

In 2014, 95 Chinese enterprises were shortlisted in the world's top 500 companies. China has shortlisted 95 of the world's top 500 enterprises, ranking second in the world. The total operating income of China's top 500 enterprises amounted to 50 trillion yuan, achieving a total net profit of 2.2 trillion yuan.
Among the 85 enterprises in the world's top 500 in mainland China, there are only 7 private enterprises, with 91.8% of State-owned and State-owned enterprises.

In the chain software, there are no more than two types of database structures. One is that all data is stored in the same database, including the headquarters, and the other is the independent headquarters database. Each branch has one database, I often use independent databases. These two methods have their own advantages. when data is stored in the same database, it is very convenient for data exchange b
