Purging cache is the process of deleting the entries from the query cache. In Siebel Analytics you can purge the cache entries in the following ways:
a) Manually, using the Administration tool cache manager facility (in online mode)
b) Automatically, by setting the Cache persistence time field in the physical table dialog box for a particular table.
c) Automatically, by setting the Siebel Analytics server event polling table.
d) Automatically, as the cache storage space fills up.
