Restriction: cpio and ULTRIX |
When using cpio on an ULTRIX client, the cpio -c option must be used. The headers created by the ULTRIX cpio utility are non-standard and not recognized by THRUnet unless the -c option is used. Note: See the cpio man page for
more information about the cpio utility. |
Upgrading to V2.4
Introduction |
This section details the procedure followed by those THRUnet users upgrading from THRUnet V2.x to THRUnet V2.4. |
Procedure: upgrading from V2.x |
To perform an upgrade from THRUnet V2.x to THRUnet V2.4, follow the steps detailed in the table below. |
|||
|
Step |
Action |
|
|
|
1 |
Make sure existing THRUnet server is running. |
|
|
|
2 |
Load the THRUnet V2.4 distribution media. |
|
|
|
3 |
Follow the installation and configuration procedures as detailed in the THRUnet V2.4 documentation, Chapter 2. THRUnet V2.4 has a new database format that is not compatible with previous versions of THRUnet. During the installation, you will be prompted to convert and save your previous database. To save this data, respond “YES”. |

Changes for Version 2.3-02
Introduction |
This section details new features, enhancements, and bug fixes for THRUnet V2.3-02. |
New feature |
THRUnet now supports the BRU™ archive utility. BRU is a robust backup and restore utility developed and marketed by Enhanced Software Technology, Inc. History files are supported for BRU. |
History file specification format |
THRUnet history files no longer require VMS format file specification. History files are now stored in native UNIX file specification format. This eliminates the need for conversion routines and enhances backup performance when history processing is enabled. |
History file naming convention |
The history file naming convention has been changed. All THRUnet history files are now formatted as follows: |
|||||
|
File type |
Convention |
|
|||
|
the saveset history file |
<machinename>_<username>.SETS_5R0 |
|
|||
|
the files history file |
<machinename>_<username>.FILES_TN23 |
|
|||
|
Note: When a user is defined with an owner field, the history
is stored in a file based upon the machine name and user name rather than the
owner name. |
|
||||
Database format change |
The THRUnet database format now allows longer media type string lengths. |

The TNTHIST utility |
A history processing utility is now included with THRUnet. This program, known as TNTHIST is available for both VAX (HISTUTIL_VAX.EXE) and Alpha AXP (HISTUTIL_AXP.EXE) platforms. TNTHIST can be used to: |
• convert pre-V2.3-02 histories to the new format, and
• clean or list the contents of a history file.
Note: You can still view history files with the TNT QUERY FILES command. However, TAPESYS history query commands will no longer work.
Media compaction |
A bug was reported in previous versions of THRUnet that prevented media compaction from working in some instances. This has been fixed. |
Device allocation error message |
If TAPESYS is running and you specify a volume (with the TNT ALLOCATE command), THRUnet uses the mediatype and location found in the TAPESYS database to allocate a device. If, when specifying a volume, you also specify a mediatype and location and it differs from those returned by TAPESYS, THRUnet displays an error message. |
Device allocation location |
Previously, THRUnet allocated a device if it exactly matched the mediatype and location specified. It now will allocate for locations that exactly match the specified “location” and any appended characters formatted as “location...”. For example, if the location name equals “Boston”, then THRUnet will attempt devices at “Boston1” or “Boston2”. |

Additional TAPESYS support |
The Allocate command now allows you to specify a Notes field and a Scratch Date. THRUnet passes this information to TAPESYS and updates the media database. To specify Notes: VMS: use the /NOTES=<notes> qualifier on the $TNT ALLOCATE command UNIX: use option “N” and include a notes string in quotes for the corresponding value To specify a Scratch Date: VMS: use the /SCRATCH=yy-mmm-yyyy qualifier on the $TNT ALLOCATE command UNIX: use option “s” on a first or third party tnt allocate command and include the Scratch Date in the form dd-mmm-yyyy for the corresponding value
|
Changes for Version 2.4
Backup and Restore |
If a backup and/or restore completes successfully with zero bytes transferred, a status of "no data transferred" is returned. |
Machine name width |
The machine name width has been increased from 31 to 128 characters. |
DEC C Run Time Library |
THRUnet is now built with the DEC C RUN TIME LIBRARY. |
UNIX command |
The UNIX command 'EU' no longer requires options 'x' or 'y'. This allows autoconfigure mode to work for UNIX client machines. |
Help information displayed |
The UNIX client now displays help information relating to command syntax. For example: 'tnt Q?' will display syntax of all Query commands and 'tnt ?' will display syntax of all commands. |
Portmapper |
The embedded portmapper has been removed since UCX now supports a reasonably functional portmapper. |
Diagnostic routines |
The server now has improved diagnostic routines. |
Bug fix |
The server would sometimes free volumes which could not be mounted because the user had no access to them. This has been fixed. |
Nounload option |
The nounload option has been fixed. |
Changes for Version 2.4-01
tar Header Format Variations |
The server has been modified to recognize additional variations in the tar header for correct check sum generation. |
Bytes Transfered Counter |
The server has been modified to accurately report bytes transfered to 15 digits within server log files. The server has also been modified to return Kbytes (1024 bytes) transfered when queried using the TNT QUERY JOB command. |
Job Completion Status |
Some failed jobs incorrectly reported a successful completion. The server has been modified to correctly report job completion status. |
