Oracle Error Message
ORA-27419: unable to determine valid execution date from repeat interval
Reason for the Error
The specified repeat interval contained conflicting clauses that made it impossible to ever find a matching date, e.g., ‘FREQ=YEARLY;BYMONTH=FEB;BYMONTHDAY=31’. Alternatively, the scheduler reached its maximum number of attempts to try to find a valid execution date. This occurs when theoretically there is a valid execution date far in the future, but the scheduler took too many attempts to determine this date.
Solution
Remove the conflicting clauses, or simplify the repeat interval so that it is easier to determine the next execution date.
