DBLOAD combines the two statements CATALOGLOAD ALL and TABLELOAD ALL to form one statement.
Syntax:
CATALOGLOAD ALL and TABLELOAD ALL are implicitly executed one after the other. The first INFILE name must therefore indicate the file with the CREATE statements for the database catalog, the second INFILE name must indicate the file containing the pertinent table contents, and the file specified after OUTFILE will receive the tables that could not be loaded.
DBLOAD can only be executed by a SYSDBA.
