A Method and System for Optimally Selecting and Using Extended Format Attributes

Disclosed is a method and system for optimally determining and using extended format data sets along with supported attributes for a user system.

The method and system disclosed herein creates a product registry table for product components for identifying the components which can support extended format data sets along with particular attributes. Initially, the registry table is filled with default values. Thereafter, a filter is used for naming conventions. The filter extracts the specific name of the data sets which is used by the product and store in the registry table for identification purpose. The registration of the product can be updated by calling the registry table. For example, a table has an entry which indicates a product supports Extended Format (y), Extended Addressable (y), Striped (n), Stripe Count (#), and Compressed (n). The existing values in the Automatic Class Selection (ACS) Storage Class and Data Class indicate a procedure for using allocated data sets. However, when the system indicates the data sets can be Extended Format, the table is checked for naming convention filters to insure the validity of allocated data sets name. If it is not valid, the restriction in the table overrides the allocated data sets.

Thereafter, the method and system additionally checks the Extended Format non-VSAM data sets for access methods. If the access methods are detected with the data sets, then the registry table entry can be updated to indicate that the data sets do not support Extended Format. If the registry table do not have an entry for the data sets name, the nam...
