Unified Intelligence Center uses a cache to optimize access to the
local Cisco Unified Intelligence Center database and it is built on top of the
local configuration database. Unified Intelligence Center is designed to
provide a highly scalable cluster in which every node manages its own local
cache independently of other nodes.
When an item stored in the local cache (such as a report template or a
dashboard) is modified, a message is sent to other nodes in the cluster
indicating that the item has been modified and that their version of that item
is stale. On receipt of this message, each node invalidates its own references
to the stale item in the local cache. In this manner, all nodes remain
In a few exceptional cases where, stale data can be re-cached or
become out of synch in the cluster. Therefore, the Unified Intelligence Center
System Configuration administrator has access to the
Synchronize Cluster link on the menu bar.
Click and confirm. This action notifies all nodes in the cluster to
clear their local cache, and it synchronizes and empties all caches in the
cluster. Clearing the locale cache forces each node to go directly to the
database for the requested information.
Each node gets fresh data from the database. The data is
automatically put into the local cache and accessed during future requests.
Data will be consistent in the database, and there will be no loss of
It is best to perform this action during off-hours.
