Oracle10g RMAN Automated TSPITR Instantiation

In previous Oracle releases, you could use RMAN to perform tablespace point in time recovery (TSPITR).  However, you needed to create an auxiliary instance manually.

In Oracle 10g, when you perform tablespace point in time recovery, RMAN creates an auxiliary instance automatically on the same target database server.  RMAN removes the auxiliary instance after you complete the tablespace recovery.

RMAN creates the data files required by the auxiliary instance as specified by set newname, configure auxname, and db_file_name_convert.  RMAN removes these files when the recovery tasks are completed.
