Install Oracle-from the begining 2

Continue from the failure yesterday.

I knew it would not go smooth.

Since the file image copied from cpttm is for 64bit, however, since my desktop only support 32bit application, I have to download the Oracle Linux for 32bit, but what follows is worse...the initial parameter setting may vary from the one for Oracle Linux x86-64bit. OK, but I need to fixed it anyway!

After dowloading the Linux ISO file, I installed the Linux OS into my VM. And, I found another problem, I actually download the Oracle Linux 6 while what I learned from the cpttm is Linux 5...well so basically I cannot follow the note given by Ken.

THe installation indeed is different from Linux 5 in which require a lot of settings. For Linux 6, I can hardly choose anything. There is one I had not configured in Linux 5 before, is the software, application type of the OS. Whether it is a basic server? database server or mail server. As this is used for Oracle, I chose database server, but then I found something wrong, the database software in the next step is MySQL!? Then I found out from the internet that database server is to configured a MySQL server, while basic server is for Oracle softeare. Odd name! On the same page, you can customize the software in the OS. In contrast to my instinct to follow the default setting, I click in the customized software setting and see what kind of application I can choose. There are a lot of tools: network tool, basic function...and X Window. 

X Window? soemething like Windows? No applicable for this Linux right? So I did not choose it.

After I finished the installation of Linux, it remains in the typical CLI HMI. Even after I logged in as root successfully, it just stayed there. What should I do with it?

As searched from the web, the command "startx" should put me to Linux desktop GUI, where I am familiar with. However, when I enter the command "startx" it returned "command not found". Afterward I found out that it is because I did not check X window application when I customize the application on my Linux.

So actually X Window has nothing to do with MS Windows, it is a GUI system in Linux. Based on WIKI:

X provides the basic framework, or primitives, for building such GUI environments: drawing and moving windows on the display and interacting with a mouse, keyboard or touchscreen. X does not mandate the user interface; individual client programs handle this. Programs may use X's graphical abilities with no user interface. As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces.

Since I exclude X windows in the Linux, the startx command cannot be recognized by the system. I then chose the most stupid way: reinstall the Linux. This time I checked all the application available, then after I logged in as root, the GUI appear. OK, I can start the configuration eventually,

To be continue.
