Open System in CTY Program

OPSx55 template

  • Specific Outcomes
  • C1: Stuff to learn: Installing, Testing, and maintaining (add/remove/modified)
  • C2: Basic shell command and script level x
  • C3: Configuration files and configuration items
  • C4: Log files and log entries (to understand the meaning of each log entry)
  • C5: Backup and recovery when system breakdown or migration
  • A6: Automation of tasks.

C1 - C5: Componets of the course - each topic has 5 components

  • C1 - subject contents: what is it for? how does it work? how to make it available to the users? how to keep it running?
  • C2 - shell command / script needed for the subject matter
  • C3 - configuration files/items for the subject matter
  • C4 - log files/entries for the subject matter
  • C5 - what need to be backed up/recovered/migrated if required

A6 - Assignment : how to automate C1 to C5 if applicable

P1 - How to get it up and running according to specification? P2 - How to create a good backup for disaster recovery? P3 - How to restore the stuff after a disaster?
