I changed a process to multiple threads to read data from DB. the original code works fine. I just change main process to multiple threads with DBPool and keep all DB code without change.
after changed to multiple thread, it throws
: ORA-01001: invalid cursor
: Closed Statement: next
Any advices for the change for multiple threads DB access?

Use only local variables for thread-safety.
