New enhancements to DFSMSrmm are intended to help improve usability, availability,
and security elements for customer using IBM's premiere tape management solution
for z/OS.
Individual improvements include:
- DFSMSrmm backup improvements: Users can now run backups of the RMM CDS and
journal at any time, even during inventory management.
This enhancement also enables users to back up and clear just the journal data
set so as to help minimize the time required.
The backup of the journal without the CDS is designed to be non-intrusive
enabling CDS updates to continue throughout the backup.
- DFSMSrmm duplicate volume support: DFSMSrmm supports multiple, physical
volumes with the same internal volume serial number.
A duplicate volume is defined to RMM using a unique volume serial number together
with the VOL1 label volser.
A duplicate volume must be a physical non-scratch standard label volume and
can be used for input and output requests.
On return to scratch, the volume is relabelled to a non-duplicate volume.
- DFSMSrmm control information: The DFSMSrmm LISTCONTROL command is updated to
display the CDS percentage used and journal status.
The operator QUERY ACTIVE command has been updated with the journal status
information.
When the status of the journal changes a new message is issued to notify the
operator.
- DFSMSrmm command authorization: DFSMSrmm optionally supports security profiles
in the RACF DATASET and TAPEVOL classes as a way to authorize the use of certain
RMM TSO subcommands against data set and volume information defined in the CDS.
This capability can provide a more flexible alternative to the use of volume
ownership for authorization for the general user.
All of these functions are supported in z/OS V1.3 and z/OS V1.4 environments.
They can be obtained by applying APAR OW56584.
