All main and worker applications must be synchronized:
- After receiving a TD_SYNC_Barrier or TD_SYNC_TELINFO status code.
- All instances should enter and exit the same following methods together:
- Initiate
- Checkpoint/Restart
- EndAcquisition
- ApplyRows
- Terminate
Because of the synchronization, the instance on the slower machine will affect the instance on the faster machine. Teradata strongly recommends that you run all of your instances on machines that have the same power throughput.
