5.3.4  Storing data in Virtual Storage Access Method datasets
Another way to store data on the z/OS system is through Virtual Storage Access Method 
(VSAM). Content Manager OnDemand can create objects that are stored in VSAM datasets. 
All storage management issues for VSAM datasets, such as allocation, backup, and 
migration, apply for these object datasets.
To create a storage set that stores objects in VSAM datasets, the Content Manager 
OnDemand administrator must provide the first-level qualifier for the defined cluster 
statement. In the example that is shown in Figure 5-16 on page 118, VSAMTST is the high 
(first) level qualifier.
Tip: Content Manager OnDemand and OAM can run in different DB2 subsystems 
(different DB2 subsystem identifiers (SSIDs)).
