Object access method (OAM) processes very large, named byte streams (objects) that have no record boundary or other internal orientation. These objects can be recorded in a DB2 database, file system, optical storage volume, or tape storage volume. OAM uses SMS policies to provide information lifecycle management for these objects. For information about OAM, see z/OS DFSMS OAM Application Programmer's Reference and z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide for Object Support.
