Thanks Michael. Also for other rule resources like .drl or .dsl and using
Drools - Expert, can we change the rules on the fly.

1) Please read about KnowledgeAgent, but you'd still need to upload the
revised worksheet to Guvnor.

2) Please read about AgendaEventListener's re: which rules fired. Guvnor
maintains audit history for "who" changed rules, but I'm not sure whether
there's a (public) API to retrieve this other than through Guvnor's UI.

  Hi,

  I have some queries about Drools - Guvnor :

  1) Is hot deployment possible in Guvnor, how can we do that? How can we
  change rules on fly? eg we are using Decision Table for rules and if we
  change some data in that sheet, how will the changes get reflected in the
  rule engine?

  2) Does the rule engine maintain a log file (in expert as well as in
  Guvnor). How to do an Audit check eg. for getting which rules were fired,
  which user changed the rules and at what time?

  Thanks & Regards,
  Sumeet Karawal
