Figure 5-16   Defining a storage set for VSAM
Based on these parameters, Content Manager OnDemand creates VSAM datasets during 
the arsload program. A catalog entry is created, as shown in Example 5-2.
Example 5-2   VSAM dataset name
VSAMTST.FAA.L1.FAAA 
This catalog entry is created automatically by the Content Manager OnDemand system. The 
only part that you can create for yourself is the first-level qualifier. The space allocation during 
the Define Cluster is performed by the Content Manager OnDemand code, as well. The 
default object size that is set when you define the application group influences the number of 
bytes for the primary allocation and the secondary allocation. The number of bytes is divided 
by 16 for the primary allocation. Every time that an arsload command runs with this storage 
set, this amount of data is allocated even if the objects are much smaller.
Every load creates two VSAM datasets: one VSAM dataset for the data, and one VSAM 
dataset for the index. Every Define Cluster of a VSAM dataset is a catalog entry. If you have 
several million loads with this storage set, your catalog grows large.
Y ou can browse the VSAM dataset, but if the compression is on, you cannot see much. For 
test purposes, compression can be switched off and then the content of the VSAM dataset is 
viewable. Compression can be switched off on the load information in the application window.
If you store AFP data to VSAM, the resources are stored in a different VSAM dataset.
