Doc36: Clear Cache

Title: Clear Cache

You can force Traction to clear its caches by clicking the Clear Caches button.

This will cause:

All config files to be re-parsed. For example, you may need to do this after installing a new skin or custom view, listener, SDL tag, or other plug-in.
Data (e.g. user profile information and group membership) cached from external directory servers to be flushed. The user's next access will refetch this information from the directory server. (Note: this cache is normally refreshed every five minutes)
Cached Traction articles and other data structures to be flushed. As a result, the first few views after clearing caches may take slightly longer than normal to complete.
Java Garbage Collection, to release any memory being used by unreferenced objects.

In most cases, clearing caches is sufficient to cause a server configuration change to take effect. One notable exception is that the server must actually be Rebuild, Restart, and Shutdown for new locales to be added, or for modifications to existing locale files to take effect.

Cache Manager

Traction 3.7 and later include a special interface that lets you selectively clear caches. Type /cachemanager into the Rapid Selector search box to access the Cache Manager interface. You can select the caches you wish to clear, then press the "clear selected caches" button.

This can be used, for example, to force re-parsing of configuration files in order to install a new plug-in while not causing a large principal cache to be jettisoned.
