ABSTRACT:
A method, apparatus, and article of manufacture accesses a dataset using an unsupported access method. A first request to access a dataset is intercepted. The first request is associated with a first data structure that specifies a first access method. The first data structure is replaced with a second data structure that specifies a second access method which is different from the first access method. The dataset is accessed in accordance with the second access method of the second data structure.In another particular embodiment, the first access method is the basic direct access method, and the second access method is any of the basic sequential access method and the queued sequential access method. In yet another embodiment, the dataset is an extended format physical sequential dataset.
