1 Using This Tutorial

This chapter provides information that you must know before using this tutorial.

Intended Uses

This tutorial is designed to be used in one of the following ways:

  • A quick overview of the steps needed to configure resources (such as single-instance databases) using Oracle Fail Safe to ensure high availability of the same

  • A step-by-step introduction to using Oracle Fail Safe Manager

This tutorial provides the basic steps for configuring resources to make them highly available; it does not provide detailed information on the concepts behind high availability. You may find it helpful to refer to the Oracle Fail Safe Concepts and Administration Guide while using this tutorial.

The following terminologies are frequently used in this tutorial:

  • Cluster: A group of independent computing systems that operates as a single virtual system.

  • Failover: The process of taking cluster resources offline on one node and bringing them back online on another node. This process can either be planned (upgrades or maintenance) or unplanned (system failure).

  • Group: A logical collection of cluster resources that forms a minimal unit of failover. In a failover situation, the group is moved to a failover node. A group resides on only one cluster node at a time. In newer versions of failover clusters, "service or application" or "clustered role" is referred to as a group.

  • Resource: A physical or logical component that is available to a computing system. For example, disks, the network IP address, Oracle databases are resources.

  • Virtual address: A network address at which the resources of a group can be accessed, regardless of the hardware server hosting those resources.

  • Virtual server: A group with one or more virtual addresses.
