'''Object access method''' is an [[access method]] under [[z/OS]] which is designed for the storage of large numbers of large files, such as images. It has a number of distinguishing features, e.g. compared to [[Virtual storage access method|VSAM]]:

*OAM datasets do not have anyan internal record structure,; they are accessed as binary data streams.

*OAM datasets are not directly cataloguedcataloged. Rather, they are stored into OAM collections, with only the OAM collection being cataloguedcataloged. The reason for this is to prevent the cataloguecatalog from being overloaded with large numbernumbers of (e.g. image) files.

OAM is meant to be used in conjunction with [[IBM_DB2|DB2]]. An example use case for OAM would be storing medical images in a DB2 database running under z/OS.
