Learn To The Oracle Linux 7: System Administration course covers a range of skills including installation, using the Unbreakable Enterprise Kernel, configuring Linux services, preparing the system for the Oracle Database, monitoring and troubleshooting. This course teaches you how to handle typical issues faced by administrators. You learn to understand the kernel development model and learn about Linux distributions. You hear about Oracle's comprehensive solutions and Oracle's contributions to the Linux community. Learn To: Enable kernel features. Set up users and groups. Configure system logging, the boot process, the network and storage. Install additional software packages. Keep the kernel up to date by using Oracle Ksplice. Configure services such as NTP, NFS, FTP, OpenSSH, firewalld and iptables. Benefits to You Oracle Linux brings you the latest Linux innovations, delivering extreme performance, advanced scalability, and reliability for enterprise applications and systems. Implementing Ksplice provides you zero down time kernel updates. Prerequisites Suggested Prerequisite Archiving and compressing files in Unix; performing remote connections and file transfers Types of user accounts and working with files and directories in Unix Unix shell command line features and basic shell scripting Text editing using vi and Unix process control Required Prerequisite UNIX and Linux Essentials Shell Programming Ed 1 Audience Database Administrators Database Administrators System Administrator System Administrator Support Engineer Support Engineer Technical Consultant
