Tuning UNIX course description
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.
Who will benefit?
System administrators.
Network administrators.
Support personnel.
UNIX training course prerequisites
Essential UNIX administration
Knowledge of shell programming and C would be useful though not essential.
UNIX training course objectives
By the end of the course delegates will be able to:
- Customise the UNIX kernel.
- Use UNIX tools to analyse problems.
- Monitor the performance of UNIX.
- Add and remove device drivers to and from the UNIX kernel.
- Tune the UNIX system.
- Describe the organisation and implementation of the filesystem.
Duration: 5 days

NOTE: The exact contents of this course will depend on the
specific variation of UNIX (e.g. AIX, HP/UX, Linux or Solaris)
required. |
