The first step is to design the replication environment. This example demonstrates how to replicate the HR.EMPLOYEES
and HR.DEPARTMENTS
tables at the master sites DBS1 and DBS2. DBS1 is designated as the master definition site for the system.
See Oracle Database Advanced Replication for detailed information about planning and designing your replication environment.
Note: The primary key of HR.EMPLOYEES
is the EMPLOYEE_ID
column, and the primary key of HR.DEPARTMENTS
is the DEPARTMENT_ID
column.
