CHAPTER 1
V2R6.1.1 Features and
Discrepancy Reports
This chapter describes new software features for Teradata Database Release V2R6.1.1 and
updates to the software that affect user documentation.
The following sections describe the features and updates for V2R6.1.1:
•
New features for V2R6.1.1
•
Requests for change (RFCs), which describe features that have been implemented for
V2R6.1.1

New Features
Teradata Database on SUSE Linux Enterprise Server 9 with More Than Four
Nodes
Starting with V2R6.1.1, Teradata Database is available on SUSE Linux Enterprise Server 9 on
more than four nodes, with a few limitations. Teradata Database V2R6.1.1 on SUSE Linux
Enterprise Server 9 does not support the following:
•
Channel-attached systems.
•
Data migration from 64-bit SUSE Linux Enterprise Server 9 to 32-bit platforms (MP-RAS
and Windows).
•
Full upgrade and backdown. SUSE Linux Enterprise Server 9 requires a fresh installation.
In addition, some row sizes and data types increase in width for 64-bit architectures. For more
information on this and for detailed requirements for running Teradata Database V2R6.1.1 on
SUSE Linux Enterprise Server 9 on more than four nodes, see the Base System Release
Definition for V2R6.1.1.
Requests for Change
Requests for Change (RFCs) provide a mechanism for introducing new features and tracking
major enhancements to existing features.

Requests for Change
Note: For most maintenance releases, changes to the user documentation in response to RFCs
are documented only in the Release Summary and are added to the individual Teradata books
for the next major or minor release.
RFCs in V2R6.1.1
The following RFCs have been incorporated into V2R6.1.1.
RFC
Description
Teradata Books Affected
57103
With the exception of DBS replacement
characters, all double-byte characters from the
Unicode 4.1 standard are now be accepted into
the database. Quadruple-byte characters
represented by surrogates are not supported.
Previously, only characters from the Unicode 2.1
standard were supported.
• International Character Set
Support
• Introduction to Teradata
Warehouse
Other changes from this DR include:
• The User-Defined Area from U E000 to U
F8FF (inclusive) is accepted into the
database.
• Users can now enter and retrieve U F8FF
directly into the database. Because U F8FF
continues to be used by the database as the
vargraphic error character, users of Graphic
data may be affected.
96214
For SUSE Linux Enterprise Server 9 only:
None
This RFC enables the front panel dump switch
on SUSE Linux Enterprise Server 9 nodes with
Teradata Database installed. The code is being
moved from a separate package, panicnmi, to
part of PDE. The change will be picked up in the
required fresh installation of SUSE Linux
Enterprise Server 9.
In order to use the dump switch on non-TPA
nodes, customers need to install the panicnmi
package.
97030
For SUSE Linux Enterprise Server 9 only:
None
This RFC ports the internal tool gettbl to SUSE
Linux Enterprise Server 9. The gettbl tool
determines which database table is associated
with a bad sector on a disk.
101279
For SUSE Linux Enterprise Server 9 only:
None
Whenever a user tries to set a new desired
version for PDE, ctl checks that the version is
available on the system. If the desired version is
not available, ctl sends an error message.

GPL-compliant PDE driver source code is
installed on customer systems, which will
automatically compile the source when a new
SUSE Linux Enterprise Server 9 kernel is
installed. Customers will be able to run on a
newly released SUSE Linux Enterprise Server 9
kernel without installing a new PDE package.

For SUSE Linux Enterprise Server 9 only:
This DR standardizes the default locations used
by Teradata Database for dump, temp, and
config directories. The default directories are
changed to:
• Teradata Replication Solutions
Overview
• Database Administration
• Utilities
Configuration directory: /etc/opt/teradata/
tdconfig
Temporary directory: /var/opt/teradata/tdtemp
Dump directory: /var/opt/teradata/tddump
Software Discrepancy Reports
Discrepancy Reports (DRs) provide a mechanism for tracking updates and corrections to
software and to the documentation affected by updates.
Teradata plans to incorporate all updates documented here into appropriate user
documentation and republish the Teradata book set at the next major or minor release.
The exceptions to the above for Teradata Database V2R6.1.1 are the following documents for
internal users:
•
Upgrading to V2R6.1.1 on NCR UNIX MP-RAS and Linux Systems
•
Upgrading to V2R6.1.1 on Microsoft Windows Systems
•
Migrating Data to V2R6.1.1
These books are being published to support V2R6.1.1 and have been revised in accordance
with the DRs that affect them. These books are available at:
