It was developed in the late ’80s as a prototype product for an insurance company to replace microfiche and has since evolved into one of the most widely used data-archiving solutions on System z* servers. OAM views an object as a data stream and no matter what the object contains—company emails, billing statements, medical images—OAM can store any object up to 2000 MB. OAM is part of DFSMSdfp, a base element of z/OS*, and is typically used for storing archive-type data.
