| To Be Assigned |
his course will enable participants to enhance their system administration skills to maximize the availability of IBM System p hardware, determine the causes and solutions associated with system problems, create a secure system and perform advanced tasks not available through SMIT.
This course is targeted for system administrators with at least three months experience in AIX and with other relevant education.
Participants should be familiar with various system administration tasks. They should be able to use the basic tools and commands available to help with system administration such as, SMIT, grep, find, mail, and chmod. Participants must be able to perform basic file manipulation and file system navigation. They must be able to define basic file system and LVM terminology and carry out basic system installation activities including the setup of printers, disks, terminals, users and software. Finally, participants must be able to manage AIX processes. This knowledge can be gained by attending IBM AU13 and Au14 (AIX System Administration I : Implementation) courses.
- Perform problem determination and analyze the problem by performing the relevant steps, such as running diagnostics, analyzing the error logs and carrying out dumps on the system.
