From the above we could see that.
1) An new auxiliary cdb instance is created.
2) CDB datafiles are stored in the auxiliary
destination.
3) PDB tablespace manzoor is restored in the actual
location.
4) Recover is done until the specified scn.
5) TTS export and import done.
6) Tablespace is made
online.
