Figure 7-22 CF cache update panel in ISMF
SMS storage class changes
After defining your cache sets, you need to assign them to one or more storage classes (SC)
so that data sets associated with those SCs are eligible for VSAM RLS by using Coupling
Facility cache structures.
Follow these steps to assign the CF cache sets:
1. Select option 5, Storage Class, from the ISMF primary option menu for storage
administrators
2. Select option 3, Define, and make sure, that you specified the right SCDS name
3. On the second page of the STORAGE CLASS DEFINE panel enter the name of the
Coupling Facility cache set you defined in the base configuration (see Figure 7-23 on
page 407).
4. On the same panel enter values for direct and sequential weight. The higher the value, the
more important it is that the data be assigned more cache resources.
