If the output.sql file has not exported
anything other than the Postgres Pro transaction header and footer,
there are two possible reasons:
The Perl script ora2pgpro dumps
an ORA-XXX error: that means that your DSN
or login information is wrong, check the error and your settings,
and try again.
The Perl script says nothing, and the output file is
empty: the user lacks permission to extract something from the
database. Try to connect to Oracle
as super user or take a look at the directive
USER_GRANTS above and in the next
section, especially the SCHEMA directive.
