Object Access Method (OAM) Usage

The Control‑V IOASMON Archive server retrieves reports from the OAM through the OSREQ application interface.

The resources (devices) defined in IOASPRM for media type OAM are logical devices. A logical device task is activated whenever a request is made to access a dataset that is not already being handled by another logical device. Each logical device handles only one dataset at a time.

Up to 100 logical devices can be activated at a time depending either on the value specified for Control‑V installation parameter MAXCONN or, optionally, the maximum number set through a START or STOP operator command. If the maximum number of logical devices are active concurrently and additional requests are made, those requests wait in a queue for an available logical device.
