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 checked with all the nested view and the status is valid during that time.
FYI, the view have function, materialized view, view and table.
Every time the cursor invalidated happen, the query from the DTS will become slower and slower.
Any idea what the cause of it or how to trace the problem?
Thanks And Best Regards,
Kien Way

I have checked with all the nested view and the status is valid during that time.
Error message says the "cursor" is getting invalidated, not any of the underlying objects.
Try the process with no degree of paralellism.
