Usage

Using data set models

Data set models are currently used only to specify attributes of the work files used by the REORG utility. For more information about how it uses data set models, see REORG.

Data set model duration

Data set models are transient entities that, once created, exist in memory for the life of the database session in which they are created. They are not stored in a dictionary.

Defining dummy files

You can define attributes for a dummy file by creating a data set model whose dsn-expression resolves to the character string NULLFILE. This is equivalent to specifying DUMMY on a DD JCL statement.
