In last article, we discussed step by step environment readiness before starting installation of oracle database 19c on Linux/Oracle Linux 8.x version. but in this article we will learn the step by step guide, Installing oracle 19c on Linux. In this article we will learn in detail how to oracle 19c step-by-step installation on Linux.

Before starting oracle 19c installation on Linux

How to ready environment before starting Installing Oracle Database 19c on Linux/Oracle Linux 8.

Step -1

First, need to download oracle database 19c zip file for Linux x86–64. as downloading process starts, system will prompt to save the file, by default the file will save into download folder.

use wget command to download the installation file.



We are now going to copy the installation files to the ORACLE_HOME location “/u01/app/oracle/product/19c/dbhome_1” that we created in the previous step and unzip the downloaded oracle database installation file.

[oracle@oraclelinux dbhome_1]$ unzip -q

Start Installation

For interactive mode, I generally launch the installer through MobaXterm. Download MobaXterm on the Host machine, open a console and connect to your Linux machine using ‘ssh’ and IP address of the Linux machine with oracle user, as shown in the screenshot below.

Run oracle installer

Navigate to the folder where you have unzipped the Oracle using MobaXterm console and execute ‘runInstaller’.

[oracle@oraclelinux /]$ cd /u01/app/oracle/product/19c/dbhome_1
[oracle@oraclelinux dbhome_1]$ ./runInstaller

Oracle 19c installation started

Then you will see the installation wizard started, first the oracle splash screen then wizard ask to click on Next to move next step. if you counter an issue ” [INS-08101] Unexpected error while executing the action at state: ‘supportedOSCheck” then click on below link

How to resolve INS-08101 Unexpected error

Once you resolved the above issue then the normal installation wizard will start and again the same error [INS-08101] will not appear.

Step 1:

Click create and configure a single instance database

Step 2:

select the class on which environment you want to install server. Here we will select “server Class” to install on central server.

Step 3:

On the basis of requirement and license agreement, we will select database edition. Here we will select Enterprise Edition as the taken license from Oracle.

Step 4:

Next, we will choose oracle base path as we already set in file while configuration .bash_profile environment.

Step 5:

Oracle database will choose the oraInventory directory to save installation files. and select the group name that has the privileges of oraInventory directory.

Step 6:

select the type of database that we want to create as for the environment requirements.

Step 7:

Provide the information of Global database and SID. IF you want to create a container database, then follow oracle official documentation.

Step 8:

Here, adjust the memory allocation that you oracle will use to reside data.

Step 9:

in Next step, will specify the database file location.

Step 10:

Step 11:

enable or disable database recovery location, from where we can recover the database in case of any disaster.

Step 12:

Create a password for system level users. it can be set separately for each or can be set single for all users.

Step 13:

step-by-step oracle installation-operating groups

Step 14:

if we set root password in below screen, oracle database wizard will run the scrips automatically. else we need to execute the scripts separately from terminal with root user.

Step 16: Summary

Step 17:

Step 17-1:

we already had done configuration in Step-14 to proceed automatically, here just we click on Yes button to proceed.

Step 17-2:

Step 18:

If you encounter error ” [INS-20802] Oracle Database Configuration Assistant failed”, then use below link to follow how to resolve issue. once the issue resolve then click on “Retry” button to proceed the process.

This is the last step of oracle database 19c installation on Linux/Oracle Linux 8.9 version.

Post Installation steps

1- After oracle successful installation, First need to start oracle “Listener” or check Listener status with below commands but error message “Command not found”

[oracle@testora bin]$ lsnrctl start
bash: lsnrctl: command not found
[oracle@testora bin]$ lsnrctl status
bash: lsnrctl: command not found

2- Run below command to find the processes are running and oracle service

[root@testora ~]# ps -ef|grep smon
oracle 11803 1 0 Sep04 ? 00:00:01 ora_smon_testora
root 48834 48755 0 10:54 pts/0 00:00:00 grep –color=auto smon
[root@testora ~]#

3- Switch to user oracle and locate oracle home directory.

[root@testora ~]# su oracle
[oracle@testora root]$ . oraenv
bash: .oraenv: command not found
[oracle@testora root]$ cd /u01/app/oracle/product/19c/dbhome_1/bin

4- Run oraenv file to configure oracle SID

[oracle@testora bin]$ . oraenv
ORACLE_SID = [oracle] ? testsora
The Oracle base has been set to /u01/app/oracle
[oracle@testora bin]$

5- Now find the oracle environment with ora parameter.

[oracle@testora bin]$ env |grep ora
[oracle@amsora bin]$

6- after all above configuration done, we will check Listener status

[oracle@amsora bin]$ lsnrctl status
