5.2.3  Content Manager OnDemand storage management
The storage management criteria that you specify for the Content Manager OnDemand 
library server determines where and when Content Manager OnDemand stores reports and 
how those reports are maintained. 
Figure 5-4 illustrates Content Manager OnDemand storage object relationships. When a 
report is loaded into Content Manager OnDemand, it is assigned to an application group. The 
application group is associated with a storage set. The storage set contains one or more 
storage nodes that can be used by several application groups that have the same archive 
storage requirements. 
Figure 5-4   Content Manager OnDemand storage objects
For example, a storage set can be used to maintain data from different application groups that 
must retain documents for the same length of time and require the data to be kept on the 
same type of media. Different storage sets can be created to handle different data retention 
requirements. One storage set can be set up to maintain data on cache-only magnetic 
storage. Another storage set can be set up to point to a Tivoli Storage Manager client node 
that stores a copy of the report in archive storage.
If Tivoli Storage Manager is used as the ASM, the same storage management criteria must 
be specified for both Content Manager OnDemand and Tivoli Storage Manager. That is, the 
Life of Data and Indexes in Content Manager OnDemand and the retention period in Tivoli 
Storage Manager must have the same value.
