Jonathan, I don't see how this can be done. I am using the Standard RAM Cache manager to cache the results of a couple of scripts(python). I am not writing a new Product, just using zope default components. All I want to do is invalidate all cashed results let's say with a single mouse click. The purpose of this is to give the user a possibility to refresh the view whenever he wants to. This means in between the Cache Managers cleanup_interval. May be a way to achieve this would be to set the cleanup_interval to 0 and then back to the original value. But this seems to be also a kind of sick, if it will work at all. However, thanks for your input Juergen -----Original Message----- From: Small Business Services [mailto:toolkit@magma.ca] Sent: 20 April 2004 16:26 To: Rauch, Juergen (Juergen); zope@zope.org Subject: Re: [Zope] RAM cache invalidation From: "Rauch, Juergen (Juergen)" <juergen.rauch@optimay.com>

The 'Flush Cache' tap hyperlinks to 'Control_Panel/Database/manage_cacheGC'. The StandardCacheManagers don't have a 'manage_cacheGC' function. At least I couldn't find one. I didn't really make any progress so far. May be I have to extend the interface of the RAM Cache Manager to get this working.

If you are working with python products/external methods to implement your application, could you subclass your RAM cache manager to get access to the 'manage_cacheGC' utility? Jonathan
