The Events_ConfigurationV[X] view contains rows for each archive activity that does not affect all AMPs in the Teradata Database configuration.

If the activity is for all AMPs and there are AMPs off-line, a row is inserted for each off-line AMP. If the activity is for specific AMPs, a row is inserted for each AMP that is specified and online.

Corresponding Tables

The X view references these additional tables:

  • DBC.AccessRights
  • DBC.DBase
  • DBC.Owners
  • DBC.RoleGrants
  • DBC.Roles

CreateDate and CreateTime

The CreateDate and CreateTime columns are updated by the PE on which the session is running. That is, all events for a given session are timestamp-ordered.

However, if multiple or concurrent sessions are running on different PEs, any discrepancy in AMP clocks may be reflected in the timestamp sequence. This may also occur if a Teradata Database is connected to more than one client system and the client system clocks are not synchronized.

Possible Values for EventType

  • CHECKPOINT
  • RESTORE
  • DELETE
  • ROLLBACK
  • DUMP
  • ROLLFORWARD
