Running Oracle Database Setup Wizard to Install Oracle Database


Log in as the Oracle installation owner user account (oracle) that you want to own the software binaries.

Download the Oracle Database installation image files (db_home.zip) to a directory of your choice. For example, you can download the image files to the /tmp directory.

Create the Oracle home directory and extract the image files that you have downloaded in to this Oracle home directory. For example:

$ mkdir -p /u01/app/oracle/product/18.0.0/dbhome_1

$ chgrp oinstall /u01/app/oracle/product/18.0.0/dbhome_1

$ cd /u01/app/oracle/product/18.0.0/dbhome_1

$ unzip -q /tmp/db_home.zip

From the Oracle home directory, run the runInstaller command to start the Oracle Database Setup Wizard.

$ cd /u01/app/oracle/product/18.0.0/dbhome_1

$ ./runInstaller

In the Select Configuration Option screen, select Create and configure a single instance database.

Select your installation type.

When prompted run root.sh as root user.


[root@prodapp /]# /appstier2/app/oracle/product/18.0.0/dbhome_1/root.sh
Performing root user operation.

The following environment variables are set as:
    ORACLE_OWNER= orauser
    ORACLE_HOME=  /appstier2/app/oracle/product/18.0.0/dbhome_1

Enter the full pathname of the local bin directory: [/usr/local/bin]:
   Copying dbhome to /usr/local/bin ...
   Copying oraenv to /usr/local/bin ...
   Copying coraenv to /usr/local/bin ...


Creating /etc/oratab file...
Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root script.
Now product-specific root actions will be performed.
