6.1.3 SMS Storage Class

Some DB2 installations may use only one Storage Class for DB2, but in others, the DB2 administrators may require several Storage Classes for DB2 table spaces. Table 12 on page 49 shows four examples. These are:

SCDBMED

This Storage Class is intended for the majority of table spaces. It

 

provides good performance and good availability.
