While I was recovering the production database backup in staging environment. I got the below errors.

ORA-19755: could not open change tracking file
ORA-19750: change tracking file: ‘/u02/oradata/test/ofsap_blk_change.dbf’
ORA-27037: unable to obtain file status

This error occurred because “The block change tracking file got deleted or the file is not backed up”. The block change tracking file is mainly used to speedup the backup processes. We can disable this and proceed further.

Solution :-

alter database disable block change tracking ;

recover database;
