1.2.1 I/O Modules & OAMs
The LANSA Repository details for files are included in Input/Output Modules. These modules are called I/O Modules (IOMs), or Object Access Modules (OAMs). IOMs are only used on the IBM i in partitions that are not enabled for RDMLX or where no OAM exists. OAMs are used for all other file requests.
