Switching the Systems
This is the 4th part of a blogger series describing how to easily create runable shadow copies of productive systems using Sun Solaris 10 native OS virtualization functionalities (Solaris Zones). These shadow systems can be used for applying updates, patches or similar tasks which would result in a downtime of the productive system otherwise. In this part the steps performed in part 2 and part 3 are demonstrated using a simple bash script. In the second part the productive system and the shadow system are switched as shown in Part 3.
