Oracle Job Scheduling

Chapter 3 - Time-Based Job Scheduling

Calendar Syntax in Oracle10g

PARAMETER

MEANING

byday

Specifies the day or days of the week with reference to the frequency using the three letter abbreviation. When used with a yearly or monthly frequency, the day can be prefixed with a number.  Prefixing the day with a number indicates the occurrence of that number within the frequency, with negative numbers providing a backwards count.
