[rules-users] Best practise, configuration in DB or in a BRMS

[Ross H]

Just a few comments on the use of Guvnor in a production environment that
may be of interest. We are using 5.1.1 Guvnor and Drools-Server configured
with a KnowledgeAgent.

Early testing showed that if Guvnor was unavailable and a scanner was
configured, the KnowledgeAgent would unsubscribe from the resource and
remove the rules. We were also concerned about "accidental" deployments, the
"Oops, I didn't mean to do that" situation!

To overcome this we decided to decouple Drools-Server from Guvnor and
created a simple package admin ui within Drools-Server to stop the scanner,
pull a package from a URL (generally Guvnor) and restart the scanner. In
this situation the scanner only looks at a local directory. A little bit
more effort to deploy, but this gives a lot more control over deployment of
packages for those rules applications that are business critical.

I remember seeing some comments about a push mechanism from Guvnor some time
ago. This might be a good enhancement.

Regards Ross.
