Update the SMS configuration
For DFSMSdfp to use the CF for VSAM RLS, after defining one or more CF cache structures
to MVS you must also add them in the SMS base configuration.
Define cache sets
In 7.14, “Coupling Facility structures for RLS sharing” on page 397 we discuss how to define
CF cache structures. You now need to add the CF cache structures to the DFSMS base
configuration. To do so, you need to associate them with a cache set name.
The following steps describe how to define a cache set and how to associate the cache
structures to the cache set:
1. From the ISMF primary option menu for storage administrators, select option 8, Control
Data Set.
2. Select option 7, Cache Update, and make sure that you specified the right SCDS name
(SMS share control data set, do not mix up with SHCDS).
3. Define your CF cache sets (see Figure 7-22 on page 406).
