Description
Description:
Scenario:
- Shared Nothing
- Two inference agents (inf1 and inf2) are deployed in FT mode.
A rule based timer event is scheduled by the primary agent (inf1). When the primary agent (inf1) is brought down, the secondary agent (inf2) is activated. When the time is reached to trigger the timer event, the event is not triggered.
Scenario:
- Shared Nothing
- Two inference agents (inf1 and inf2) are deployed in FT mode.
A rule based timer event is scheduled by the primary agent (inf1). When the primary agent (inf1) is brought down, the secondary agent (inf2) is activated. When the time is reached to trigger the timer event, the event is not triggered.
Issue/Introduction
While using Shared Nothing, a rule based timer event scheduled from a primary engine is not triggered from the secondary engine.
Resolution
Rule based timer
events will not be recovered in Cache only mode. Fail-over of rule
based timer events require cache plus memory cache mode. Shared Nothing
persistence works in cache only mode. For Shared Nothing persistence, the workaround
is to use the scheduler instead of rule based timer events.
