For VMware Identity Manager, database replication is configured so that data remains consistent across database servers within the primary data center and across to the secondary data center.

Whether you are using the vPostgres internal database or configure an external database to work with VMware Identity Manager, you must configure your database for high availability. Configure a master and slave database architecture, where the slave is an exact replica of the master.

To set up your external database for high availability, refer to your external database documentation.

To set up the internal VMware Identity Manager database as a master and slave configuration for high availability, see KB 2094258, Using embedded vPostgres database for VMware Workspace Portal 2.1.
