Creating a Copy of the Preinstallation Configuration File for the grid User

Create a copy of the preinstallation configuration file for the grid user to set hard and soft limits for the operating system parameters.

1. As the root user, go to the /etc/security/limits.d directory.

   # cd /etc/security/limits.d

2. Create a copy of the preinstallation configuration file for the grid user by replacing the oracle user with the grid user.

   # cat oracle-database-preinstall-19c.conf | sed 's/oracle /grid /g' > oracle-grid-user-preinstall-19c.conf

3. Delete the preinstallation configuration files for the earlier release.

   # rm -r -f oracle-database-preinstall-18c.conf oracle-grid-user-preinstall-18c.conf
