The Forms service takes form designs that were created
in Designer and renders them in various formats.
The Forms page in Administration Console contains settings that
control the way the Forms service caches items. You can adjust these
settings to optimize the performance of the Forms service.
The Forms service caches the following items:
form designs: The Forms service caches form designs
that it retrieves from the repository or from HTTP sources. This
caching improves performance because for subsequent render requests,
the Forms service retrieves the form design from the cache instead
of from the repository.
fragments and images: The Forms service can cache
fragments and images used in form designs. When the Forms service
caches these objects, it improves performance because the fragments
and images are only read from the repository on the first request.
forms: The Forms service caches the forms that it
renders. This type of caching improves performance because the Forms
service does not need to resolve and render the same form in subsequent
requests.
Forms stores the cache in two locations:
in memory: Items are stored in memory for quick
access. The in-memory cache has a limited size and is deleted when
you restart the server.
on disk: Items are stored in the server’s file system.
The disk cache has a larger capacity than the in-memory cache and
it is retained when you restart the server. The location of the
disk cache depends on your application server. For information on
changing the location of the disk cache, see Configuring locations for Forms.
