|
History | No | Determines if historical values are stored, and if so how many.
The default maximum value is 32767. Zero (0): TIBCO BusinessEvents does not store historical values for the concept. It stores the value without a time and date stamp One or more (>0): TIBCO BusinessEvents stores the property value when the property changes, along with a date and timestamp, up to the number specified. When the maximum history size is reached, the oldest values are discarded as new values are recorded. See TIBCO BusinessEvents Architect’s Guide for more details. Note:
Use of a temporal function with a concept that has a history size of 0 may cause a runtime exception.
