Allocating Space for Table Spaces and Indexes

To acquire space for DB2 table spaces and indexes, use IDCAMS to allocate a VSAM data set for each table space or index, or reference a storage group when creating the table space or index. A storage group identifies one or more DASD volumes available for DB2 table spaces and indexes.

The Data Store List documents how to decide to use storage groups or IDCAMS to acquire DB2 space. When you use storage groups, CA Gen generates the JCL to run the appropriate DDL. When you use IDCAMS, CA Gen generates the JCL to run the IDCAMS control statements and DDL.
