combinations of these names. This provides the installation with great flexibility in implementation alternatives, such as:

High Level Qualifier Filter

The ACS routines contain a list of high level qualifiers. These qualifiers are used to assign the specific SMS classes. The high level qualifiers can provide a meaningful distinction between data of different DB2 subsystems. This method is recommended as a starting point, because of its simplicity. Some installations may have multiple, complex requirements and may prefer to use another method.

A variant of this method is used in the example shown in Appendix A, section A.4, “DB2 Table Spaces Using SMS, Existing Names” on page 165. In this appendix, Figure 92 on page 168 shows an ACS routine that assigns Management Classes based on a high level qualifier (which is also the DB2 subsystem name). The variant introduced is that certain databases (name starting with B) in the DB2D susbsystem are assigned a separate Management Class.

Database Name Filter

The ACS routines contain a list of DB2 databases. The database name is used to assign the specific SMS classes. All table spaces and index spaces within a database would have the same SMS classes. When a new database is created, the ACS routine has to be modified.

Table Space Name Filter

The ACS routines contain a list of DB2 databases and table and index spaces. These names are used to assign the specific SMS classes. Each table space and each index space can have distinct SMS classes. When a new table or index space is created, the ACS routine has to be modified. This technique is only manageable in static installations. A simple example of an ACS routine using this method is shown in Figure 18 on page 55.

High Level Qualifier Codes

The high level qualifiers contain a Storage Class code and a Management Class code. These codes are used to assign the specific SMS classes. Multiple high level qualifiers are required to obtain a meaningful distinction between data with different requirements.

Database Name Codes

The DB2 database names contain a Storage Class code and a Management Class code. These codes are used to assign the specific SMS classes. All table spaces and index spaces within a database would have the same SMS classes. The ACS routine does not need maintenance for new databases. This method provides a resolution at database or application level.
