Optical Disk Volume Maintenance Window
The Optical Disk Volume Maintenance window lets you create, modify, delete and view optical
disk volumes available for storing archived reports. This window provides a way for notifying
VISTA Plus of available optical disk volumes. It also defines the sequence VISTA Plus will use to
search optical disk volumes when determining the next volume to which to write a report.
To define reports to archive to optical disk, you need to first enable the Archive to Optical Disk flag
in the Archive Rules window. This flag must be enabled for each report you want to archive to
optical disk.
Optical Disk Volume Maintenance can be used to define optical disk volumes. The group and
account names assigned to each volume must match the group and account names that were created
on the volumes when the optical disk was installed.
Execute the VISTACLN program to remove aged reports from a folder and have them archived to
optical disks. When the VISTACLN process removes a report from a folder, it checks the Archive
to Optical Disk flag. If this flag is enabled, a search of available optical disks is performed to
determine the optical disk volume to which to write the report. When a volume is found, the report
is placed in the group and account associated with the optical disk volume.
The search for the next optical disk volume occurs in ascending order based on the field Volume
Number within each optical disk volume record. A check is also made to verify that space is
available on a volume to retain the report removed from a folder. If space is not available, then the
search continues with the next volume.
When a report is stored on an optical disk volume, VISTA Plus retains the volume name to which
the report was written. This allows VISTA Plus to restore a report from an optical disk volume.
The procedure for restoring a report archived to an optical disk is the same as the procedure for
restoring a report from a tape. Within VISTA Plus, the Select Archive window can be utilized to
select reports to restore. This window can be displayed with the function key labeled “Archived
Reports” on the Select Report window.
To select reports to restore, tag the report by pressing F4, Tag Reports. Press F6, Execute Restore
to initiate the restore operation. VISTA Plus will launch a batch job to perform the restore.
To view the Optical Disk Volume Maintenance window, enter 11 in the function field and press
Enter. The window on the next page will be displayed.
