Installing Oracle 19c on Windows Server

Hi everyone, in this blog I have shown the steps to install Oracle software (enterprise edition) for single instance on Windows server.

Download oracle software file from https://www.oracle.com/database/technologies/oracle19c-windows-downloads.html or you can use https://edelivery.oracle.com

Step 1 : Frist step is different from previous version Oracle installation and an important one. You have to create db_home location on server and place extracted software file inside that location.

For eg., I created a folder D:\app\oracle\product\193000 and placed extracted oracle software file inside that location.

Step 2: Click on setup file inside db_home. Oracel universall installer will pop up.

 

Step 3 : In Configuration Option select Set up software only to install oracle 19c software only and click Next.

Step 4 : In database installation options select single instance database installation to only install binaries and libraries required to support single instance database and click next

Step 5: In database edition option select Enterprise Edition to install enterprise oracle database features libraries and binaries and click next.

Step 6 : In this option choose your type of Oracle home user and click next

a) exisiting windows user

b) Windows built-in account (Not recommended)

c) virtual account (Doc ID 2224768.1)

d) new windows user

Note : Oracle home user is the owner of Oracle Services that run from Oracle Home and cannot be changed after installation. You must not log in to the Oracle home user to perform administrative tasks.

For single-instance Oracle database installation, Oracle recommends that you use Virtual account or a standard Windows user account

Refer : https://docs.oracle.com/en/database/oracle/oracle-database/12.2/ntqrf/using-oracle-home-user-for-oracle-single-instance-database-and-oracle-database-client.html#GUID-399882FD-7A38-446D-A4B4-9426A4A57213

Here i am creating  new windows user 

Step 7 : In installation location enter Oracle base location. As you can see Oracle database home is selected by default and you can't change this. This is why we have to create db_home folder first in 19c unlike other version database installation. Software directory is the location where you kept your extracted installation folder. So software directory and Oracle home directory will always be same.

Step 8 : In this step Oracle setup performs prerequisite check. Status of all the checks should be succeeded. If the status is not succeeded click on Fix & check again.

Verification Result on top must show : All minimum requirements are satisfied. You may proceed with the installation.

Step 9 : Check your settings summary and click on install

You can see at the bottom there is an OraMTS Port number which we didn't setup. What is this OraMTS??

OraMTS is a Oracle MTS Recovery service which is automatically installed with Oracle services in windows. It accepts requests to resolve in-doubt MS DTC-coordinated transactions started on this computer

For more information on OraMTS read this : https://docs.sdl.com/802001/79043/sdl-knowledge-center-2016-sp3/oracle-rdbms

or you can check out oracle docs

Step 10 : Installation

Step 11 : Check the installation log files in cfgtools location ($ORACLE_HOME\cfgtoollogs\cfgfw). At last run sqlplus -v to check the version.
