DFSMS provides the following functions to help you more
easily manage data residing on optical and tape volumes:
- Interactive Storage Management Facility
- ISMF lets you define attributes for optical libraries and optical
drives interactively.
- MVS system commands
- OAM and SMS allow you to display the following information:
- Object access method status (the number, type, and availability
of defined optical drives in the active configuration)
- A summary of the name, type, and status of OAM control tasks,
and information about object processing status
- Details about the number, type, and status of object processing
for a specified control task
- Optical and tape library, optical drive status, and
tape drive status (online, offline, connectivity to the system).
- Object Access Method
- The object access method (OAM) lets you create, access, and
delete objects on optical, tape, or disk storage.
You define SMS groups and classes to establish the following operating
conditions:
- Object storage medium hierarchies and requests for a backup copy
of an object
- Whether
the object resides on optical, tape, or disk storage
- When to migrate an object from one storage medium to another
- The number of backup copies of an object assigned to an object
or object backup storage group
- Object expiration sequences
- Parallel Sysplex
- A Parallel Sysplex® allows you to link
multiple systems together to communicate and share data through the
cross-system coupling facility. XCF services allow authorized applications
on one system to cooperate with and share data with applications on
the same system or on other systems within the sysplex. Because a
sysplex facilitates parallel processing on multiple systems, objects
can be accessed from all instances of OAM and from optical hardware
within the sysplex. This allows transactions to be processed more
efficiently.
