the network returns to a normal state. This saves sig-
nificant time and system resources when large files are
transferred.
File Backup
DTF for OpenVMS allows OpenVMS users to target IBM
disks and tapes for backup and restore operations. In
large co-resident HP and IBM sites, this capability opti-
mizes system resource usage. Users have the ability to
include an allocation space qualifier when backing up
files to target IBM disks to ensure proper disk space
availability.
Remote Job Submission
DTF for OpenVMS users can submit jobs remotely from
all clients.
Post-Processing
Using DTF for OpenVMS, OpenVMS, and IBM, users
can provide a post-processing file to be executed after
a file transfer is completed. This feature allows Open-
VMS and IBM users to logically connect the running of
a batch job to the successful completion of a DTF file
transfer. This makes the implementation of distributed
processing functions significantly easier to synchronize
between IBM applications and OpenVMS-based appli-
cations.
Record-Level Access
DTF for OpenVMS supports record-level access from
OpenVMS systems to IBM mainframe systems.
Supported File Types
DTF for OpenVMS supports multiple file types (RMS,
VSAM, and BSAM), allowing easy applications devel-
opment. DTF also supports mixed case IBM file speci-
fications.
HSM Support
DTF for OpenVMS supports IBM’s Hierarchical Storage
Management (HSM) facility.
IBM Enterprise Architecture and SMS Support
DTF for OpenVMS runs in compliance with IBM’s Enter-
prise Architecture and will support SMS-managed data
sets (refer to the Supported IBM Configurations section).
Data Translation Using Load Balancing and
Performance Tuning
DTF for OpenVMS supports text translation from HP
DMCS (Digital Multinational Character Set, a superset of
ASCII) to EBCDIC and vice versa on a record-by-record
basis. DTF for OpenVMS supports load balancing and
performance tuning between the IBM system and the
OpenVMS DTF server node by allowing users to select
which system performs the text translation. Enhanced
performance of the OpenVMS DTF server often results
when this translation is performed on the IBM system.
Data Security
DTF for OpenVMS controls access and protects valu-
able data with superior security capabilities. The main-
frame component supports the industry-standard SAF
security interface that runs on IBM machines.
Proxy access to the IBM system allows OpenVMS users
to access the mainframe system without IBM user IDs
and passwords flowing over the network connections.
Server Management
The DTF for OpenVMS product includes a management
utility to manage the OpenVMS DTF server.
Event Logging
The mainframe component logs events which can be
used for historical inquiry or accounting. System pro-
grammers can easily write specialized accounting and
bill-back reports using DTF’s logs.
