Hiperbatch is a VSAM extension designed to improve performance
in specific situations. It uses the data lookaside facility (DLF)
services in MVS to provide an alternate fast path method of making
data available to many batch jobs. Through Hiperbatch, applications
can take advantage of the performance benefits of MVS without changing
existing application programs or the JCL used to run them. For more
information about using Hiperbatch, see
MVS Hiperbatch Guide.
Note: Effective with DFSMS in
z/OS 1.3 and above, VSAM clusters defined as extended format or extended
addressable may use Hiperbatch.
