The first object in the storage control file is a Defaults object. If no actual value exists for a given object, but a value for that object is required by a DB2 statement, then the default value is either derived from the Defaults object or inherited from a higher-level object.
You can override default values for any given object by explicitly defining the value in the object. For example, if the Tablespace object does not contain PriQty or SecQty values, then these values are inherited from the PriQty and SecQty values defined in the Defaults object. However, if the values are defined in the Tablespace object, then the explicitly provided value overrides the default and is used in the output DDL.
NOTE: If you create an extension table in Siebel Tools, and you use the apply process without creating new underlying objects for this table in the storage control file, then the necessary storage layout is derived from the default definitions. For information about the apply process, see Applying Schema Changes to the Target Database.
