[rules-users] Guvnor JCR repository

Hi Guys, I am using Guvnor 5.5. For moving packages between environments, I am doing an export, and then import in the new package. I have a lof of assets in each package. I am using the DB storage for the jcr repository. After some months, the DB has grown a LOT! (like 3.5GB). Is there a way regularly clean the JCR history, or maybe disable JCR history as we are not using it at all? These are the steps I did to remove the history and seems to work fine. Does is seem safe? Is there a better way? 1. Export the entire repository via guvor. 2. Delete all the packages. 3. Stop tomact 4. "truncate" the following guvnor tables: a. Pm_ws_default_binval b. Pm_ws_default_bundel c. Versioning_pm_binval d. Versioning_pm_bundle 5. Restated tomcat 6. Import what I exported on step #1 Thanks! Demian
