Hi all!
I have encountered an error in a transaction.

When the application try to insert n .pdf or .jpg files in a table (field in BLOB data type), in dependence on them sizes it fail. The error generated is the ORA-00001: unique constraint (string.string) violated but the sequence that populate the _id works!

In another db the transaction works, and the only difference between the first and second database is the edition: where fail we have the Standard, the other is Enterprise.
