  **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. You 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. 
  
  **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. 
  
  **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.
