Week Overview
Change Management Revision Control Time Management
Change management is an organized effort to implement changes to a system
Change Management
Typically, change management involves the following elements:
The goal is to complete the changes with minimal impact on the users and related systems
Communication is a vital component of all change management stages All steps should be properly documented
Planning Implementation Evaluation
Revision control in the technological side of the change management Usually, revision control uses software to keep track of changes to systems or software Revision history allows tracking of changes and quick reversion of changes in case of problems
Revision Control
Revision control is heavily used in software development, but system administrators can use the same tools to control vital elements of their systems configuration files, accounts etc.
Revision control should not be confused with backup
Linux has several software tools available for revision control Perhaps the most popular and simplest to use is the RCS package
Revision Control for Linux
You will need to install RCS on your systems from source code
Complex scenarios can be addressed though other tools such as CVS and Subversion
As a nonroot user:
RCS Installation
Download the latest version of RCS Untar the source Run the ./configure script Compile the source using make
You will need the gcc package installed
As a root user:
Install the software using make install
RCS Usage
Files brought are under RCS control through checking them in and out Use the ci utility to check in files Use the co utility to check out files Notes:
RCS stores version differences By default, the version file is created in the same directory as the original
Use ./RCS subdirectories if you want to keep version files separately
Use the l option (locking) when you wish to edit the file
Lock is counterintuitive remember that it is seen from the RCS side
Time Management
Time management, although being a commonsense term requires training In it, good time management boils down to using available time efficiently
Prioritize your tasks Plan out your work Delegate tasks (if you can) Learn how to deal with others users and management
Especially learn how to deal with interruptions
