Step by Step Oracle 19c Binary Installation and Database Creation On Linux


This article is a continuation of the previous article where we have completed prerequisite and binary installation for 19c on Linux 8, click here to read more about it. In this article, we are going to demonstrate Part 2 database creation Step by Step Oracle19c (19.3) enterprise edition binary Installation and database Creation On Linux 8.3 (OEL) using GUI mode which will be on a multitenant architecture (CDB & PDB). We will complete this article in three parts.

1.  Prechecks / Prerequisite {Completed in Part 1}
2. Oracle 19c binary installation (runInstaller) {Completed in Part 1}
3. Oracle database creation (DBCA)

3.  Oracle database creation (DBCA)


3.1. Set up environment variables: Add below entry in .bash_profile resides in user oracle home directory. In our demonstration it resides on /home/oracle.

export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=DBsGuruN3.labdomain
export ORACLE_UNQNAME=labcdb01
export ORACLE_BASE=/u02/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19c/db_1
export ORACLE_SID=labcdb01
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib


3.2. Execute environment variables: Here we can execute the environment variables command or go to $ORACLE_HOME/bin to execute the dbca command.

[oracle@DBsGuruN3 ~]$ export ORACLE_HOME=/u02/app/oracle/product/19c/db_1
[oracle@DBsGuruN3 ~]$ export PATH=$ORACLE_HOME/bin:$PATH
[oracle@DBsGuruN3 ~]$ which dbca
/u02/app/oracle/product/19c/db_1/bin/dbca
[oracle@DBsGuruN3 ~]$ dbca


3.3. Launch database creation assistant tool: Once you execute dbca, we can see dbca launched a screen and on the first screen, all options are disabled Create database and Manage template, since we are creating the first database for specific ORACLE_HOME. Select option Create a database and click on Next.


3.4. Creation Mode: In this screen select Advanced configuration to opt for available options like character set, memory, DB files, container, etc. according to your requirements.


3.5. Deployment Type: In this screen, select Database type: Oracle Single Instance database and Template name: General Purpose then click on Next.


3.6. Database identifier: Pass the value of Global database name / SID along with the opt-in container database with one PDB and click on Next.


3.7. Storage Option: If you want to create DB files in your desired location then select the second option and browse the directory location, now click on Next.


3.8. Fast Recovery Option: In this section, specify an archive location, size of FRA, and opt-in eenable archive. If you don’t want to enable archive then simply uncheck all boxes. Now click on Next.


3.9. Network Configuration: Specify a listener name along with a port number. If you want to create a non-default listener or dedicated listener for the database then provide the listener name and port according to that.


3.10. Database Vault Option: Skip this screen if don’t want to use Database Vault configuration i.e remain to uncheck boxes.


3.11. Configuration options: In this screen, we will click on each tab and do configuration as required.

Memory: Go with either Option-01 Automatic Shared Memory (allocate SGA & PGA) or Option-03 Automatic Memory Management (Memory target).


Sizing: Allocate value of parameter Processes, the default value is 480.


Character sets: Select here AL32UTF8 which supports multiple language groups. If any constraints/dependencies then go with your requirements.


Connection Mode: Select option-01 Dedicated server mode.


Sample Schema: Check the box Add sample schemas if you require else you may skip it and click on Next.


3.12. Management Options: Remain to uncheck the box for Enterprise Manager and click on Next.


3.13. User Credentials: Pass the value of the password for SYS & SYSTEM and click on Next.


3.14. Creation Options: In this screen, we have options to multiplex control files and redolog files. If you want then click on customize Storage Locations. Now click on Next.


3.15. Summary: This is a final screen to review the summary on the basis of steps 1 to 12 of dbca so review carefully if found anything to change then go back and change the configuration. Once you are ready click on Finish.


3.16. Progress: Take a long breath and closely monitor the progress of database creation along with the database alert log & DBCA log.

3.17. Finish: Upon successful creation of database LABCDB01, optionally you can click on Password Management to set a new password and unlock the account of sample schemas as required then click on Close.


3.18. Post Validation of database creation: Here we will perform basic validation of the database.

3.18.1: Validate database service along with listener status.
