Sometimes dump files are wanted to import your system . But if you do not know source system structure import process can be trouble.Without knowing source tablespace , schema knowledge import will produce errors .
In order to solve this issue and do successful import , impdp are called with sqlfile parameter to get all DDL statements . Output contains all DDL statements and all necessary statements can be captured .
impdp $DBUSER directory=$DIRECTORY dumpfile=$DUMPFILE.dmp sqlfile=impfile.sql
After executing above statement impfile.sql generated.For example tablespaces can be seen with ,
grep TABLESPACE impfile.sql
command which lists all "TABLESPACE" statements . You can create tablespaces according to output or "remap_tablespace" parameter for impdp is used to reconfigure tablespaces according to your system.
