Hi,
My DTS have 5 parallel transfer data from sql db to oracle db at the same time, it have come up with an error "ORA-12842: Cursor invalidated during parallel execution"
Based on the information I get is as per below:
Cause: The cursor was invalidated during the parse phase of deferred parallel processing, e.g. when set operands are parallelized.
Action: Depends on why the cursor was invalidated. Possible causes include DDL on a schema object and shared pool being flushed.
I have no idea why it related to cursor. Can someone guide?
