1. Introduction [Top] ============================================================ Overview: ========= The purpose of this exercise is to provide a DBA the opportunity to setup Dataguard on VMware's free VMware Server Product. The cost of hardware has come down significantly and it's now within an individual's budget to build a machine capable of running a virtualised database environment. This introductory article covers the setup of the VMware host on which the Dataguard (or any other env) will be built. The main steps are: i) Download the VMware Software and install it ii) Configure VMware networking iii) Setup a Guest Host iv) Clone the guest host What this is not: ================= This is not a production Dataguard setup. It provides a good starting point for a DBA to learn the core concepts of Dataguard. Aspects such as monitoring, good standards etc. are left to the reader to investigate. Disclaimer: =========== I (Ahbaid Gaffoor) will not be held responsible for any damages or loss of data incurred as a result of following these examples. |
2. VMware Terminology [Top] ============================================================ VMware uses certain terminology when referring to machines and different parts of the environment. The following is a brief explanation of VMware terms. 1. Machine Classification: Host: The host machine is the machine on which VMware Server is installed Guest: A guest machine is a virtual host installed on the host machine 2. Network Types: Bridged: A guest machine network interface that has access to the host machine's network. The guest machine ususally has an ip address on the same network as the host, this makes the guest machine accessible to the rest of the real network beyond the host as a real machine. IP addresses for a bridged network are either statically allocated or assigned by the real network's DHCP server. The bridged network interface can also have a DNS entry on the real network. NAT: NAT is Network Address Translation, the guest machine's network interface has access to the real network through the host machine's network interface. This is also known as masquerading. The guest machine is not visible from the real network. VMware runs its own DHCP service which can assign ip addresses to guest network interfaces. Host Only: The guest netowrk interface is inaccessible beyond the host machine, the guest machine can access other guest machines that have similar guest only interfaces on the same subnet mask. The host machine can also be allocated an IP on the same subnet allowing it to access guests on the Host Only network. |
