The caches apps
Caches is a collection of three cache administration apps:
- Cache statistics: Provides options to flush caches and an overview on the current memory consumption.
- Flex cache: Provides an overview on all flex cache entries and their variations.
- Image cache: Provides an overview on all cached images and their variations.
Some of the cache flushing tools provide extra options. Here we provide an overview of these options.
Flushing tools and options
- Core Cache
Core cache flushing always flushes the whole cache. No options are available. What exactly happens depends on your installation. Technically, an event is sent that can be handled in various places.
- Flex Cache
For flushing, you can choose if you want to flush the cache for online resources and if you want to flush the whole cache (keys and variations), or only the stored variations of HTML output.
- Image Cache
The image cache flushing tool allows a date to be specified, such that only images (image variations) are removed that have not been requested after the given date.
- Initialize the workplace
Reinitializes workplace related options, e.g. the workplace message bundle.Calls org.opencms.workplace.CmsWorkplaceManager#initialize(CmsObject). Additionally the core cache is flushed.
- JSP Repository
The JSP repository can only be flushed completely. Afterwards, all JSPs that are requested must be exported to the server again, before they are executed.
The Flex cache app lists all cached entries and via the context menu you can show the single cached variations. Moreover, in the toolbar, you can get the statistics of the cache's memory consumption and access to the cache flushing options for all caches.
The image cache app allows to search via a regex on the image paths to search for cached images. For each image, an overview on the cached variations is provided. Moreover, in the toolbar, you can get the statistics of the cache's memory consumption and access to the cache flushing options for all caches.
