databases, BCUSTOMR, BSERVICE, BTRANS are allocated on

SGDBFAST.

All table spaces in the development system will be allocated on

SGDBTEST.

The development databases are subject to migration by HSM. Those databases with a name starting with B will get preferential treatment.

A.4.1 Storage Classes

Using ISMF, option 5.3, the following Storage Classes were defined:

SCDBTEST

SCDBFAST

SCDBMED

SCDBCRIT

Figure 89 on page 166 shows page 1 of the associated panel used by the storage administrator to build the definition for SCDBTEST.
