This article will provide a detailed guide on Oracle database preinstallation rpm 19c download. We’ll walk you through each step of the process with proper screenshots.

1.If you plan to use the “oracle-database-preinstall-19c” package to perform all your prerequisite setup, issue the following command as a root user for Oracle database preinstallation RPM 19c download:

yum install -y oracle-database-preinstall-19c

2. If you are creating an RAC database then you must perform the following for the grid user otherwise ignore the below steps:

• Take the backup of the oracle-database-preinstall-19c.conf file:

[root@node1]# mv /etc/security/limits.d/oracle-database-preinstall-19c.conf /etc/security/limits.d/oracle-database-preinstall-19c.conf.bak

• Edit the file /etc/security/limits.d/oracle-database-preinstall-19c.conf and add the same parameter value for the grid user as oracle:

[root@node1 limits.d]# cat /etc/security/limits.d/oracle-database-preinstall-19c.conf
