ORA-27417: BYWEEKNO clause is only supported when FREQ=YEARLY
Cause: A repeat interval or calendar contained a BYWEEKNO clause with a frequency other than yearly.
Action: Remove the BYWEEKNO clause or change the frequency to yearly.
ORA-27418: syntax error in repeat interval or calendar
Cause: The repeat interval or calendar definition could not be recognized as a valid syntax.
Action: Specify a valid repeat interval.
ORA-27419: unable to determine valid execution date from repeat interval
Cause: 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.
Action: Remove the conflicting clauses, or simplify the repeat interval so that it is easier to determine the next execution date.
ORA-27421: usage of string not supported in a calendar definition
Cause: The calendar definition contained a clause that is specific for a repeat interval
Action: Specify a valid calendar definition.
ORA-27431: chain string.string has a user-managed rule set
Cause: An attempt was made to modify a rule set that is not managed by the Scheduler.
Action: Modify the rule set directly using the dbms_rule_adm package or create another chain without specifying a rule set.
ORA-27432: step string does not exist for chain string.string
Cause: The step specified does not exist for the given chain.
Action: Reissue the command using a step that exists for this chain.
ORA-27433: cannot alter state of step string for job string.string to string
Cause: The step cannot be changed to the requested state. The state of a running step cannot be changed. A step which is running or has already run cannot be run again.
Action: Wait until the step has finished running.
ORA-27434: cannot alter chain step job string.string.string
Cause: A step job of a running chain cannot be altered, only stopped or dropped.
Action: Stop or drop the chain step job or alter the running chain step instead.
ORA-27435: chain job terminated abnormally
Cause: A chain job has ended abnormally. The error code for the running chain could not be retrieved.
Action: No action necessary. The job will run again when it is scheduled to.
ORA-27451: string cannot be NULL
Cause: An attempt was made to set a NOT NULL scheduler attribute to NULL.
Action: Reissue the command using a non-NULL value for the specified attribute.
ORA-27452: string is an invalid name for a database object.
Cause: An invalid name was used to identify a database object.
Action: Reissue the command using a valid name.
