Hi Wei, Glad you are able to view the GOES data in CAVE now. The simplest solution to changing your purge rules is to back-up and then remove all the current purge rules in /awips2/edex/data/utility/common_static/base/purge except for the defaultPurgeRules.xml. Then edit the defaultPurgeRules and set the period to 7. <purgeRuleSet> <defaultRule> <period>07-00:00:00</period> </defaultRule> </purgeRuleSet> You shouldn't have to restart EDEX!
