Teradata ARC inserts rows into the RCConfiguration table for each archive activity that does not affect all of the AMPs in the configuration:
If the activity is for all of the AMPs, but some AMPs are offline, Teradata ARC records
a row for each offline AMP.
If the activity is for specific AMPs, Teradata ARC records a row for each AMP that
is both specified and online.
A row contains these attributes:
The event number assigned to the activity.
The logical identifier for the processor.
The cabinet and slot number for the processor.
A state flag of D (down) to indicate that a processor was offline during an all-AMPs
operation, or a flag of U to indicate the processor participated in a specific AMPs
operation.
A restart count to indicate during which restart of the event the row was inserted.
If the Teradata Database fails during an archive or recovery activity and the operation
is restarted and the configuration changes, then Teradata ARC writes rows to the RCEvent and RCConfiguration tables. The restart count ties these rows together.
