Creating a database using DBCA can be done in both ways, 1) either INTERACTIVE which provides GUI window to configure your options just like any other software you would install OR 2) SILENT method where you can achieve the same with a single command.
Even in the SILENT mode, you have 2 ways, 1) to use RESPONSE file 2) to exclude response file and put all the configuration options in DBCA command as shown in this post. I'll cover the SILENT installation using RSP file in another post.
Installing a database using Database Configuration Assistant's (DBCA) graphical & interactive mode is quite simple. It's just like installing any other software but here you must take few decision when going through different screens. I'll talk about it with each snap below where needed.
Interactive method seems easier but is time consuming, as you grow experienced, you'll realize that using script to create database via Silent installation method is more convenient & faster.
This post talks about Installation of Oracle Database on Oracle Linux 8. Here I am running a Virtual Machine creating using Virtual Box and have installed OL8 on it. Also, I am going with Oracle Database 19c version as it's one of the latest version which is being used in the market as of now.
If you also want to see how I have configured the VM on virtual box, please comment below and I'll create one post for that as well.
While installing an Oracle database with Silent installation method, it threw me the below error after few seconds of running the command.
[FATAL] [DBT-50000] Unable to check for available memory.
Either it's because wrong environment variable configuration OR Unsupported OS OR lack of Administrative privileges.
