But, I have set LongReadLen, on the db handle, equal to 90000000. Apparently this is an oracle problem because it acceppted data longer than its type, so my guess would be that in your table you have a char(n) column that could be enlarged before the migration. <https://support.oracle.com/knowledge/Siebel/476591_1.html> Hope this helps. And please report the version of ora2pg when asking for help. Luca
