Fast Recovery of Tables

Table 27 presents fast-recovery scenarios for the six table types available with Extended Parallel Server. For more information about the table types, see Table Types.

Important:
To ensure data integrity when you use raw, static, or operational tables, force a checkpoint or perform a level-0 backup after you modify or load the table.

Table 27. Fast Recovery of Tables
Table Type Fast-Recovery Behavior
Standard Fast recovery is successful. All committed log records are rolled forward, and all incomplete transactions are rolled back.
Temp or Scratch Temp and scratch tables are not recoverable because they are dropped when the database server restarts. All changes made to these tables are lost, and the space can be reused.
Raw If a checkpoint completed since the raw table was modified last, all the data is recoverable. Updates and deletions that occurred after the last checkpoint are lost. The raw table looks as it did at the last checkpoint. If a light append was in progress at the time of the failure, all appended records are lost on reboot.
Static If you alter a raw table to static, you can recover it only if it was not updated since the previous checkpoint. If you alter an operational table to static, you can recover it only if light appends did not occur. If light appends occurred, they are lost on reboot. If you alter a standard table to static, you can recover it successfully.
Operational All inserts, deletions, and updates are successfully recovered. All committed log records are rolled forward and incomplete transactions are rolled back. If a light append was in progress at the time of the failure, all appended records are lost on reboot.
