6.1.6 DB2 STOGROUPs and SMS Storage Groups

The concepts of DB2 STOGROUP and SMS Storage Group are different, but very similar. While a Storage Group refers to a set of volumes in an installation, the STOGROUP refers to a set of volumes containing a set of data. Different STOGROUPs can share the same disk volume or volumes.

DB2 administrators normally define many STOGROUPs for their applications. Sometimes they have STOGROUPs for each individual volume and use it to direct the table spaces to that specific volume. Other installations have STOGROUPs at database or application level.

To make the best use of DFSMS, DB2 administrators should define their STOGROUPs as before, but using a generic volume reference (VOLUMES ’*’ ). See the example in Figure 100 on page 172. The generic volume reference allows DFSMS to choose a volume based on the SMS classes assigned to a table or index space.

Sometimes these generic volume references cannot be used for DB2 STOGROUPs. This can happen, for example, during the conversion process from non-SMS to SMS management. If generic volume references cannot be used, SMS Storage Groups can be made to match DB2 STOGROUPs. One important restriction may have to be resolved; this is:

One disk volume can only belong to one SMS Storage Group.
