 impdp system/*** directory=dump_dir dumpfile=expdp.dmp logfile=corruption_check.log sqlfile=corruption_check.sql 
                                                                                                                                         
What does this sqlfile do? 

Here we have used sqlfile option, which will not import any data to the database.

This will write all DDL statements (which will be executed if a import is performed) into the file which we mentioned in the command. 

So this will read the entire DATAPUMP Export dump file and will report if a corruption is detected.
