In MySQL JDBC connector, the first argument, or catalog, to getTables() targets
the database or schema in MySQL, which is the collection of tables.
Currently, the 2nd schema argument does not seem to do anything.

ResultSet rs = dmd.getTables( "test", null, null, new String[] {"TABLE"} );
while(rs.next()) {
System.out.print(rs.getString(1) + ", " +
rs.getString(2) + ", " +
rs.getString(3) + ", " +
rs.getString(4) + ", " +
rs.getString(5) + ", " +
"\n");
}

The output of this program is a listing of tables in my local "test" schema/database:

test, null, emp, TABLE, ,
test, null, t1, TABLE, ,

So it would seem to me that the JDBC Oracle schema argument would work
the same as the MySQL JDBC catalog argument.
