Configuring Data Replication from One Source to Multiple Targets

Configuring Data Replication from One Source to Multiple Targets

You can use the Server Manager with the InitialSync, Extractor, and Applier components to replicate data from one source to multiple targets.
Data Replication does not allow replication configurations to define multiple Hive targets. In the Data Replication Console, the
Routing
tab is unavailable when the target type is Hive.
All of the targets must be of the same database type. Also, all of the mapped columns in the secondary target tables must have the same names as the corresponding columns in the primary target tables and have datatypes that are compatible with those of the corresponding columns in the primary target tables.
When you configure replication, define one primary target and multiple secondary targets. The primary target is the target database that you defined on the
Target Database
tab.
To configure and run the replication job, complete the following high-level tasks from the Data Replication Console:
  1. Define a Server Manager Main server on a machine in your environment and connect to it. The Main server does not need to run on the source or primary target.
  2. Define a subserver for each of the other target machines.
  3. From the
    Server Manager
    tab >
    Connections
    view, define a connection for the primary target database and a connection for each secondary target database.
  4. Create and save the configuration. On the
    Target Database
    tab, specify the connection that you defined for the primary target database.
  5. On the
    Routing
    tab, define each target server and connection. Optionally, perform the following tasks:
    • Filter rows by table so that different targets receive different subsets of rows.
    • Exclude one or more entire tables from replication to a particular target.
    • Rename the target schema so that each target uses a different schema name.
    • Override the apply mode or audit log table schema for a particular target.
  6. Run the replication.
