RMAN Tablespace Point-in-Time Recovery (TSPITR) 11gR2 Enhancements

One of the good new features in 11g Release 2 is that it enables us to recover from a case of a dropped tablespace. TSPITR (tablespace point in time recovery) has been around in earlier releases, but we could not recover a dropped tablespace.

here is an demo for your reference

RMAN TSPITR DEMO

Recovery Manager (RMAN) automatic tablespace point-in-time recovery (commonly abbreviated TSPITR) enables you to quickly recover one or more tablespaces in an Oracle database to an earlier time, without affecting the state of the rest of the tablespaces and other objects in the database.for theoritical part please refer oracle documentation.

Here in this demo i am going to create and truncate a table in tablespace USERS for schema(username) RAJESH and recover truncated table TEST1 of users RAJESH schema in tablespace USERS.

We can use RMAN TSPITR in the following conditions

1. Recovering data lost after an erroneous TRUNCATE TABLE statement;
2. Recovering from logical corruption of a table;
3. Undoing the effects of an incorrect batch job or other DML statement that has affected only a subset of the database;
4. Recovering a logical schema to a point different from the rest of the physical database, when multiple schemas exist in separate tablespaces of one physical database.
