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 the 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
