Hi @NikVit,
thank you for your feedback.
This is actually weird, as batch processing must work on Oracle 12 (but not Oracle 10 or 11). Could you may be check, if you are using some kind of compatibility mode in your database?
I think it is described here: https://docs.oracle.com/en/database/oracle/oracle-database/12.2/upgrd/what-is-oracle-database-compatibility.html#GUID-551DEA35-0A31-4D1C-A367-AFAF8906AEC8
Can you may be run this query on your database:
SELECT name, value FROM v$parameter WHERE name = 'compatible';
This could help us to understand, in which cases batch processing can not be used.
Best regards,
Svetlana
