In the previous article, I talked about some basic knowledge about computer networks and introduced socket. From this section, I started to get started. 1 Probability TCP:Transimission Control Protocol Transmission Control Protocol. UPD: User datav protocol user data packet protocol. Both belong to the transport layer protocol, the fourth layer in the OSI model described in the previous article. Comparison:

Abstract:
This article uses examples to show how to chat, send files to each other, and capture the screen of the recipient to save as a file in the LAN. The program also includes obtaining the IP address and computer name of the Local Machine and the other party. The first time I published an article on functions such as the rolling ListBox control, I just
A few days ago, there were some interesting examples of redirects and piping-related usage. Software communication based on TCP/UDP protocol is implemented through redirection.
There is a special file in the Linux device:
/dev/[tcp|upd]/host/port just read or write to this file, the system will try to connect: host this machine, corresponding port port. If the host and port exist, a socket connection is established. There will be a corresponding fil

understanding of us, timely correction of our mistakes, there are targeted guidance, conducive to improve learning efficiency.(2) I hope the teacher's lecture is slow.Although the rapid progress will make us spend more time outside the classroom to consolidate the knowledge, and let us have more time to prepare for the review of the final exam, but I think that steady and better, not only to deepen our memory of the knowledge points, but also help us a little time to see the teacher recommended
ORACLE-006: Remove and stop jobs, oracle006 remove jobs
Generally, you can use SQL to delete or stop a job.
Remove JOB: remove
Stop JOB: broken
First pass
Select * from user_jobs;
Find the job id, and then call
Dbms_job.broken or
Dbms_job.remove to remove and stop. The SQL statement is as follows.
Take removing a job as an example.
1. Search for and remove a JOB based on what value of the job.
