Test Cases for DB2 Recovery Data Sets 197
B.3.3 Storage Group
Two additional storage groups are defined to cater for image copy data sets,
SGDBIC and SGDICH. Table 34 on page 197 shows the distribution of volumes
across all the storage groups used in all three examples of this appendix.
Table 34. Image Copies—Storage Group Volumes
Figure 121 on page 188 shows an extract of the Storage Group ACS routine to
divide the data sets by use of the &STORCLAS and &MGMTCLAS variables:

B.3.4 Data Set Allocation Results
Again, ISMF test cases were built and executed against the updated SCDS and
the ACDS, producing the expected results.
Following the activation of the new SMS configuration, a number of image copy
data sets were allocated. Figure 137 on page 198 shows the JCL used in this
exercise.
