This course is for experienced administrators. Advanced troubleshooting techniques are shown using crash and truss. Tuning the performance of UNIX is looked at in detail along with the structure of the UNIX kernel. The course uses hands on with Solaris and Linux but can be customised for other UNIX variants
NOTE: The exact contents of this course will depend on the specific variation of UNIX (e.g. AIX, HP/UX, Linux or Solaris) required

If you need training for 3 or more people, you should ask us about onsite training. Putting aside the obvious location benefit, content can be customised to better meet your business objectives and more can be covered than in a public classroom. It's a cost effective option.
