CE-560 Not caching as CFS size in getting filled

Hi,

I have configured CE-560 for http caching by giving CFS file system of about 60Gb space. But it has been observed that every 10 days or so, this space will get filled up and hence browsing comes to a halt. I thing the content is not getting cleared and hence its getting accumulated. If I clear all the http cache manually it will start working.

Is there any way to solve this so that no manual intervention is required.

Re: CE-560 Not caching as CFS size in getting filled

Hi,

I am not too sure if there is a dynamic way to clear the cache. From what I have been able to gather from the documentation,

The cfs clear command deletes nonbusy objects from the specified cfs volume. A nonbusy object is an object that is not being accessed (read or written). The cfs clear command (without force) deletes all possible objects without generating a broken GIF or HTML message to the client.

The cfs clear force command deletes all objects, busy or nonbusy, and may generate broken GIF or HTML messages for objects that were being read from the disk when the command was executed. If an object is being written to the Content Engine disk when a cfs clear force command is executed, the application stops caching that object but still delivers the object from the web server to the client.

You could also use the clear cache command which removes all cached contents from the currently mounted cfs volumes. Objects being read or written are removed when they cease being "busy." The equivalent to this command is the cache clear or cfs clear command.

Hi,

You could use the cron feature on the CE to perform a standard automated task if you would like. You could create a cron job on the CE that launches periodically to clear the cache. If you would like to do this, please let me know and I can put together an example.

Peter, I'd like to see that example...
