Performing RMAN Tablespace Point-in-Time Recovery (TSPITR)

Purpose of RMAN TSPITR

Recovery Manager (RMAN) TSPITR enables quick recovery of one or more tablespaces in a database to an earlier time without affecting the rest of the tablespaces and objects in the database.
RMAN TSPITR is most useful for the following situations:
  • To recover a logical database to a point different from the rest of the physical database, when multiple logical databases exist in separate tablespaces of one physical database. For example, you maintain logical databases in the orders and personnel tablespaces. An incorrect batch job or data manipulation language (DML) statement corrupts the data in only one tablespace.
  • To recover data lost after data definition language (DDL) operations that change the structure of tables. You cannot use Flashback Table to rewind a table to before the point of a structural change such as a truncate table operation.
  • To recover a table after it has been dropped with the PURGE option.
  • To recover from the logical corruption of a table.
  • To recover dropped tablespaces. In fact, RMAN can perform TSPITR on dropped tablespaces even when a recovery catalog is not used.
