I can think of two things, Ajas. First, note that there is a softcache on top of the template cache. It's not widely known. It was first documented back in 2006 by Ashwin Matthews, when he was an Adobe engineer: http://blogs.sanmathi.org/ashwin/2006/07/12/tangling-with-the-template-cache /
It's also since been documented, though only barely, in both the CF 8 and 9 docs: http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=servermoni tor_07.html http://help.adobe.com/en_US/ColdFusion/9.0/Admin/WSc3ff6d0ea77859461172e0811 cbf364104-7fba.html In both cases, they only mention it, so I added a link in the comments back in 2009 to Aswhin's post. I doubt it will ever offer that level of detail. You will also see some comments I had back and forth with Ashwin, to bring out still more. It's quite important, yet many never notice it. There is no hard limit on the soft cache size, it seems. Also, they don't get garbage collected even when released, but instead only when there's high memory pressure. The soft cache is a JVM thing, and you can dig around to find more on that. There's also one other possible explanation for what you're seeing: I'm pretty sure I've seen that if you change the size of the template cache (raise or lower it), the Server Monitor count of files in the template cache will NOT go down but instead will go UP, which would be confusing and contradictory. I recall concluding that the change was indeed causing the template cache to be cleared, but again sadly these soft cache entries are not released, so the count grew well beyond what seemed should be the limit. Both of these can definitely make the template cache count less than reliable. It's a reasonable starting point. (Note also that the template cache hit ratio may also be unreliable, if what I've seen from the query cache hit ratio is proof. But that's a thread for another day, if anyone's interested.) /charlie arehart char...@carehart.org Providing fast, remote, on-demand troubleshooting services for CF (and CFBuilder) More at http://www.carehart.org/consulting From: ad...@acfug.org [mailto:ad...@acfug.org] On Behalf Of Ajas Mohammed Sent: Tuesday, September 20, 2011 2:14 PM To: discussion@acfug.org Subject: [ACFUG Discuss] CF admin template cache vs monitoring template cache We are on CF 9 Ent on Window 2003 server. The CF admin template cache is set to 1024 but when I looked at CF built in monitoring tool, the template cache shows the number as 1405. If I understand correctly, the CF admin setting drives how many templates can be cached. I am I missing something here? <Ajas Mohammed /> ------------------------------------------------------------- To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by http://www.fusionlink.com -------------------------------------------------------------
