Enhanced Tablespace Point-In-Time Recovery (TSPITR)

Tablespace point-in-time recovery (TSPITR) is enhanced as follows:

You now have the ability to recover a dropped tablespace.
TSPITR can be repeated multiple times for the same tablespace. Previously, once a tablespace had been recovered to an earlier point-in-time, it could not be recovered to another earlier point-in-time.
DBMS_TTS.TRANSPORT_SET_CHECK is automatically run to ensure that TSPITR is successful.
AUXNAME is no longer used for recovery set data files.

This feature improves usability with TSPITR.
