The Global Cardholder Synchronizer role ensures the two-way synchronization of shared cardholders and their related entities between the local system (sharing guest) where it resides and the central system (sharing host).

Only a single instance of this role is permitted on each system.

The Global Cardholder Synchronizer can synchronize the host and the guest using the following three ways:
On demand
The guest system is synchronized only when it is requested by a user.
On schedule
The guest system is synchronized on schedule using a scheduled task.
Automatically
The guest system is synchronized automatically.

The guest-to-host synchronization is always performed immediately by the GCS role, because all changes to the global partitions must be validated by the host system before they can be accepted by the guest system. The host system processes the change requests on a first come, first served basis. The Global Cardholder Synchronizer (GCS) role must stay connected to the sharing host to keep the local copies of the global entities synchronized with the host.

NOTE: The Global Cardholder Synchronizer can sync up to a maximum of 250,000 credentials.
