Oracle Error Message
ORA-03127: no new operations allowed until the active operation ends
Reason for the Error
An attempt was made to execute a new operation before the active non-blocking operation completed or a new operation was attempted before all the pieces of a column were inserted or fetched.
Solution
Execute the new operation after the non-blocking operation completes. If piecewise binds/defines were done, execute the new operation after all the pieces have been inserted or fetched.
