Overview of Creating a Replication Environmen t

Figure 1-1 illustrates the basic steps required to build a replication environment. Regardless of the type of replication site or sites that you are building, you be gin by setting up the replicated site.

After you have set up your replication sites, you are ready to begin building your master groups and materialized view groups. After you have built your replication environment, make sure that you review Chapter 6 and the chapters in Part II, "Managing and Monitoring Your Replication Environment", to learn about conflict resolution and managing your replication environment.

Before You Start

Before you begin setting up your replication site, make sure you plan your replication environment so that it meets your needs. Planning considerations include:

• De signing your replicated database objects
• Deciding on the settings of initializat ion parameters that are important for replication
• Deciding whether you want to c reate a multimaster replication environment or a materialized view replication environment, or if you want to combine both types of r eplication environments into a hybrid environment
• Deciding how you want to confi gure your scheduled links
• Deciding how you want to configure your scheduled purg es
• Deciding whether you want to use serial or parallel propagation
• If you use parallel propagation, then deciding on the degree of parallelism
• If you plan to create a materialized view environment, then deciding whether you want to use depl oyment templates to create the environment
• Analyzing your environment for possib le conflicts and, if conflicts are possible, then deciding which conflict resolution methods to use
• Configuring security for your replication environment
• Design ing your replication environment for survivability
