Cache Data
The Cache Data setting determines whether the report data is stored in a hard disk drive 
cache and, if so, how long it is kept in cache before it is expired. Y ou can also choose whether 
to search cache when users retrieve documents for viewing. If you choose not to store reports 
in cache, you must select a storage set that supports archive storage. 
Life of Data and Indexes
The Life of Data and Indexes settings determine the length of time that report data, indexes, 
and resources are maintained in the Content Manager OnDemand system before they are 
deleted from the application group. The report data, indexes, and resources can be 
maintained indefinitely if set to never expire, or they might be kept for up to 273 years. After 
the maintenance threshold is reached, the arsmaint command can be used to expire the data 
from the system.
Note: Data that is retrieved often needs to generally remain in cache until it is no longer 
needed by 90% of Content Manager OnDemand users.
