Hi, I'm using this drools 5.0 scenario: agent using changeset file pointing to a LATEST package guvnor URL. The guvnor docs says how to start the agent resource scanning to make the engine change aware: - ResourceFactory.getResourceChangeNotifierService().start(); - ResourceFactory.getResourceChangeScannerService().start(); I suppose once the agent gets the packages from guvnor and caches it, it should not need guvnor anymore unless there are changes. The agent could use the cache and guvnor could be offline for a long time. This worked on version 5 M1. You could even restart the engine and it started using the cached version. The problem I have with the latest 5.0 with new Knowledge classes ang changeset.xml: when guvnor is offline, the resource scanning detects this and unsubscribes the package, leaving the engine without any knowledge. When guvnor is up again, the resource scanning cannot detect it, and the engine remains without any knowledge. How do I tell the agent to not unsubscribe url's that are offline, not to remove their knowledge and just use the cache ? Can I still configure the cache directory ? Maybe the problem I have is that I'm using the LATEST packages and not snapshots ? The point here is to make the engine totally independent of Guvnor when it got a package once. Hope anyone can help me. Maybe I'll try version 5.1 to see what happens then guvnor is down. Thanks, Wesley.
