You might be thinking, why is it necessary to specify schemas versus perform full import or why create SQL file?
$ cat impdp_full02_user.par
directory=DATA_PUMP_DIR userid="/ as sysdba" metrics=Y dumpfile=full.dmp logfile=impdp_full_user.log schemas=GGS_ADMIN,DEMO include=USER sqlfile=user.sql
There are 5 users imported which correspond to EXU8USR view.
If users already exists in the new database, wouldn’t create user just fail?
From demo below #schemas=GGS_ADMIN,DEMO (commented) which will
import SYS/SYSTEM/OUTLN

One good reason to create SQL file is to know what changes will be made to DB ahead of time.
