4 Working with Data Replication

You can perform all data replication tasks from the Administration Server home page. You can add Extracts and Replicats after creating your deployments.

Before you begin creating Extract processes, you need to:

• Add trandata or schematrandata
• Enable supplemental logging for SQL Server CDC capture
• Create and enable heartbeat tables.

Before creating Replicats, you need to:

• Create the checkpoint table

You'll also create a user with the admin role from the Administration Server. The initial user created during deployment is a security admin role. The security admin user should not do other tasks. So, you need to create users with the admin role and this user is used to create Extract and Replicat processes.

Users in Service Manager deployment are different from Administration Sever deployment. Service Manager deployment. users are created from the Service Manager web interface, and normal deployment users are created from the Administration Server web interface. Users in Service Manager deployment have control of Service Manager functions like stopping, starting, enabling, and disabling services. Users created from the Administration Server can create Extract, Replicat, and other processes.
