Fixes: Describes the issues resolved since general availability.
Version 7.1.6
Enhancements
The Driver Manager has been upgraded to version 8.0. The purpose of
this upgrade is to have all DataDirect for ODBC drivers use the latest
version of the Driver Manager, which allows for faster security updates
and a consistent user experience. Note that the Driver Manager is
backward compatible. As part of this upgrade:
The following ICU library files have been added to the product
package:
For UNIX: libivicu28.so (32-bit) and libddicu28.so (64-bit)
For Linux: libivicu.so (32-bit) and libddicu.so (64-bit)
The trace library file names have been changed for both UNIX and Linux:
32-bit: From ivtrc27.so to ivtrc28.so
64-bit: From ddtrc27.so to ddtrc28.so
Note 1: libivicu27.so (32-bit) and libddicu27.so (64-bit) will continue to
be included in the product package to support driver functionality. Note 2: The Driver Manager build included with the product is 08.02.1997 (U1987).
For Linux platforms only, the ICU library files that are installed with
the product have been upgraded to version 74.1. In addition, the ICU library
file names have changed for Linux platforms:
For the 32-bit driver: From libivicu27.so to libivicu.so
For the 64-bit driver: From libddicu27.so to libddicu.so
This upgrade is available starting in build 08.02.0965 of the ICU library
files.
For Windows platforms, the trace library file names have been changed from ivtrc27.dll to ivtrc28.dll (32-bit) and from ddtrc27.dll to ddtrc28.dll (64-bit) to
have the same file names across all platforms. This change allows for
faster release of security updates and a more consistent user
experience. Note: To support the trace library file name change, the following
ICU library files have been added to the product package:
ivicu28.dll (32-bit) and ddicu28.dll (64-bit).
A Password Encryption Tool, called ddencpwd, is now included with the product package. It encrypts passwords for secure handling in connection strings and odbc.ini files. At connection, the driver decrypts these passwords and passes them to the data source as required. See Password Encryption Tool (UNIX/Linux only) for details.*
The drivers using base version B0649 and later have been enhanced to include timestamp in the internal packet logs by default. If you want to disable the timestamp logging in packet logs, set PacketLoggingOptions=1. The internal packet logging is
not enabled by default. To enable it, set EnablePacketLogging=1.*
The Driver Manager for UNIX/Linux has been enhanced to support setting the Unicode encoding type for applications on a per connection basis. By passing a value for the SQL_ATTR_APP_UNICODE_TYPE attribute using SQLSetConnectAttr, your application can
specify the encoding at connection. This allows your application to pass both UTF-8 and UTF-16 encoded strings with a single environment handle.
The valid values for the SQL_ATTR_APP_UNICODE_TYPE attribute are SQL_DD_CP_UTF8 and SQL_DD_CP_UTF16. The default value is SQL_DD_CP_UTF8.
This enhancement is available in build 07.16.0398 of the driver manager.
The new NamedIDBehavior config option allows you to determine whether the Name attribute of NamedID fields is exposed in the relational map. This option can be used to avoid "poor performing query" errors by reducing the size of result sets. Refer to "Poor performing query" error message and NamedIDBehavior (Config Option) for details.*
The new Min Long Varchar Size connection option allows you to fetch SQL_LONGVARCHAR columns whose size is smaller than the minimum imposed by some third-party applications. Refer to Min Long Varchar Size for details.
The new Varchar Threshold connection option allows you to fetch columns that would otherwise exceed the upper limit of the SQL_VARCHAR type for some third-party applications. Refer to Varchar Threshold for details.
Changed Behavior
The product package no longer includes the ODBC Cursor library file
(odbccurs.so) because it has some known security vulnerabilities that
could potentially expose you to security risks.* Note: The installer program cannot remove the ODBC Cursor library file
automatically while installing a new version of the driver. Remove it
manually.
