Chown commandChown is a command used to set file owners and file associations in Unix systems. Super User Permissions are required to execute this command. OnlyOnly the file owner of a Super User and a group can change the file association group. Non-privileged users (non-Super Users) may need to set an association groupUse the chgrp command.Usage

Note: at ordinary times, many administrators may say that this machine is a 2-way 4-core hyper-threading machine, which actually means almost the same. (But many times he does not know what two-way 4-core hyper-threading means ,).
Get down to the truth and understand the image:
(1) socket is the number of CPU slots inserted on the motherboard, that is, the "path" that the Administrator says.
(2) core is what we usually call "core", that is, dual-core

The authors note: The JDO and CMP-style ejbs are moving forward at the same time, but taking different routes. JDO's core idea is to store traditional Java objects (Plain old Java Objects, hereinafter called POJOs) at different
EJB2.0 finally gave us an operable container management persistence (CMP) model. Whenever possible, I use CMP beans in my EJB project, but I need to turn my entity into Bean management (BMP) Because of this strange thing. I use the following pattern to let me cleanly transition from the CMP model to the bean management Persistence model.
In this article, we will

CMP is used to compare two files in bytes. If the two files are the same, CMP does not display any content. Otherwise, CMP displays the number of bytes and row numbers corresponding to a different
CMP (x, y): Compares 2 objects, which are less than the latter return-1, and equal returns 0, greater than the latter returning 1.

The CMP functions of Python can be compared between the same type, or between different data types. The comparison size is then determined based on the return value of the Pyth

EJB has two main types: BMP (bean managed persistence) and CMP (container managed persistence), which have their own advantages and disadvantages.
BMP is used to call database JDBC in bean. That is to say, in your entity bean, SQL statements such as "insert .. "or" select .. ", and use datasource to obtain a database resource and connection to directly add, delete, and modify the database.
