SMSDCIX in macro DSN6SPRM

Specifies a DFSMS data class for indexes. Before you set this parameter, you need to define the data classes for your index data sets. You also need to code SMS automatic class selection (ACS) routines to assign indexes to one SMS storage class and table spaces to a different SMS storage class.

SMSDCIX is one to eight characters long. When you use DFSMS and DB2® storage groups, you can use the subsystem parameters SMSDCFL and SMSDCIX to assign table spaces and indexes to different DFSMS data classes. If you assign a value to SMSDCIX, DB2 specifies that value when it uses Access Method Services to define a data set for an index. If the value for SMSDCIX is one or more blanks, DB2 does not specify a data class when it creates data sets for indexes.

The default value of SMSDCIX is a blank.

This subsystem parameter is deprecated in DB2 10.
