Introduction to Oracle installation script code

If you are very depressed about the actual operation steps of the Oracle installation script. You can browse the following article. I found an Oracle installation script on a reputable website, including some preparation activities such as modifying the host name, setting kernel variables, and creating users.

In this way, you don't have to repeat the same job. The following is the script I compiled and the Oracle Installation notes I just installed yesterday. There is no time to test it now ):

The test is complete.
