I have been in the Oracle DBA industry for several years, but speaking of Oracle Installation experience, I am not very familiar with it. At the beginning, I was a little confused, as Oracle has become more and more familiar with the principles and mechanisms of various aspects, it is rare to install Oracle.

Basically, the method for installing Oracle can be classified into the following three phases:

Now let's look back to the conclusion that errors may occur during installation, which is generally caused by failure to follow the official operation procedures. Therefore, we strongly recommend that you refer to the operation procedures in the official documentation when installing Oracle, read these installation documents at least once to help you avoid some inexplicable installation errors.

I compared the installation of Oracle software with the installation of a common software, and found that there is basically no difference between the two, but we often do not pay attention to it, as shown below:

Remarks

Any software depends on the operating system. Therefore, any software must run the operating system that meets the requirements.

Generally, software requires a certain amount of space. Therefore, any software installation must meet the requirements of the file system space.

The running and installation of any software cannot leave the memory.

Any software is composed of code. At least components that can parse and run the code are required. This is also a dependent component.

Although the installation and running of the software do not depend on the host name, a meaningful host name will omit a lot of troubles in the future.

If the software needs to be connected by other machines, we usually need to configure the network, but we do not pay much attention to it.

　

Generally, we create an exclusive running user for the software.

It must all exist. We cannot allow a software to initiate thousands of processes or anything. This is a limitation.

Some permissions are required for running the software. Therefore, we usually grant it some privileges.

For example, each software must run with a PATH variable, but most of the time we do not pay attention to it.

　

Other points
