ORACLE DATABASE IN 3 COMMAND LINES "ONLY" (Version 18c XE and 19c EE)

# ----------------------------------

# Create a VM using VirtualBox.

# ----------------------------------
# The idea is create a VM as simple as possible. In this demonstration LAB that I am creating here, will fit for the versions XE and EE as well, we can have the same VM/Linux Installation for both tests.

# ----------------------------------
# VM Creating.
# ----------------------------------

OS: Oracle Linux 7.8 x86_64
Memory: 4 GB
SWAP: 8GB
DISKS: 1 Disk of 50GB
FS: XFS
Packages: BASIC (It's not necessary others package for this LAB during this installation).


# After installation of Linux on this VM, you can configure the "/etc/hosts" with the name of the server and the it's ip, this step is mandatory for the database creation.

# ----------------------------------
# 18c (Version XE)
# ----------------------------------
# To install all necessary packages on Linux, just execute this command, just it and all necessary packages will be installed for the Oracle Softwares.

yum -y install oracle-database-preinstall-18c-1.0-1.el7.x86_64.rpm


# ----------------------------------

# To install the Oracle XE software, just download and save the RPM Package, use this link to download it: 
https://download.oracle.com/otn-pub/otn_software/db-express/oracle-database-xe-18c-1.0-1.x86_64.rpm

# ----------------------------------
# Once the download it's done, just execute this command to install the Oracle XE Software.

yum -y localinstall /tmp/oracle-database-xe-18c-1.0-1.x86_64.rpm


# ----------------------------------

# After the installation process is done, we have to create the database, just execute that command and the database will be created, the SID will be: XE

/etc/init.d/oracle-xe-18c configure


# ----------------------------------

# This command asks you to insert the password of this instance.

# ----------------------------------
# That is it, after the database creation, you have to connect on the Oracle User, and connect on the database using sqlplus, (don't forget to setup the variables using . oraenv).

su – oracle

. oraenv <<< XE

sqlplus / as sysdba

select host_name
  , instance_number
  , instance_name
  , version
  , version_full
  , status
  , database_status
  , instance_role
  , instance_mode
  , database_type
  , edition 
from gv$instance
order by 1, 2;


# Look my example here!!!

# NOW THE 19c ENTERPRISE EDITION VERSION

# ----------------------------------

# ----------------------------------
# Install the pre-install package.

yum -y install oracle-database-preinstall-19c-1.0-2.el7.x86_64.rpm

# ----------------------------------
# Install the software (you have to download it first, www.oracle.com/downloads
).

yum -y localinstall /tmp/oracle-database-ee-19c-1.0-1.x86_64.rpm


# ----------------------------------
# Create the folder where the database instance will be saved.

mkdir -p /opt/oracle/oradata/
