Obiettivi


Enrolling in this course will help you work towards becoming a knowledgeable Oracle Linux System Administrator. You will install Oracle Linux, configure services, and gain an understanding of the benefits of Oracle's Unbreakable Enterprise Kernel(UEK).


Learn To:

  • Configure systems to use the UEK and enable kernel features.
  • Perform initial system configuration; set up users and groups, configure system logging, networking, and storage.
  • Install additional software packages.
  • Keep systems up-to-date using Oracle’s Unbreakable Linux Network.
  • Keep the kernel up-to-date using Ksplice technology.
  • Configure services available in Oracle Linux, such as: DHCP, DNS, NFS, Samba, FTP, OpenSSH, NIS, LDAP, PAM, Web and Email.
  • Secure, monitor and troubleshoot systems.
  • Prepare Oracle Linux systems to run Oracle Database.


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.
