Changes Since 7.1.6 GA
Windows Runtime Version Upgrade
-------------------------------
Some components of the driver are now compiled with a Visual Studio 2022
compiler for Windows platforms. As a result, you must have Microsoft
Visual C/C++ runtime version 14.40.33810 or higher on your machine to
run the driver.
JRE Requirement for the Installer
---------------------------------
The installer program now requires you to install a JRE that is Java SE 11 or
higher before running the installer. In earlier versions, the JRE used by the
installer program was included in the product. However, to avoid potential
security vulnerabilities, the installer program no longer includes a JRE.
Instead, the installer program uses the JRE in your environment to allow for
the most secure version of a JRE to be used.
Notes:
* This change does not affect the JVM requirements for the driver. For the latest
driver requirements, refer to the Product Compatibility Guide:
https://docs.progress.com/bundle/datadirect-product-compatibility/resource/
datadirect-product-compatibility.pdf
* The installer program cannot remove the already installed JRE files from the
install directory automatically. Remove them manually.
ICU Library Upgrade (74.1)
--------------------------
The ICU library files that are installed with the product have been
upgraded to version 74.1. As a part of this upgrade, the ICU library
file names have changed:
* For the 32-bit driver: From ivicu28.dll to ivicu.dll
* For the 64-bit driver: From ddicu28.dll to ddicu.dll
Notes:
* This upgrade is available starting in build 08.02.1072 of the ICU
library files.
* ivicu27.dll and ddicu27.dll will continue to be included in the product
package to support driver functionality.
Trace Library File Name Change
------------------------------
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)
SSL Enhancement (3.0.9)
-----------------------
Note: OpenSSL library 3.0.9 has been replaced with a later version. For
the latest information about the third-party components that are installed
with the product, refer to the ODBC Third-party Components Compatibility
Matrix on the DataDirect Product Life Cycle page:
https://docs.progress.com/bundle/datadirect-product-life-cycle/page/topics/
datadirect_life_cycle/datadirect-product-life-cycle.html.
The default version of the OpenSSL library has been upgraded to version
3.0.9, which fixes the security vulnerabilities listed on the following
page: https://www.openssl.org/news/vulnerabilities-3.0.html
This upgrade is available in build 08.02.0595 of the following OpenSSL
library files: ivopenssl30.dll (32-bit) and ddopenssl30.dll (64-bit).
Notes:
* The driver supports the following OpenSSL 3.0 providers: Default and
FIPS.
* The FIPS provider is supported only on the following platforms:
Windows 64-bit, Linux 64-bit, and AIX 64-bit.
* The following connection options have been added to configure the
driver to use OpenSSL 3.0: Enable FIPS (EnableFIPS), OpenSSL Config File
(OpenSSLConfigFile), and OpenSSL Provider Path (OpenSSLProviderPath).
For more information on the new connection options and how to configure
the driver to use OpenSSL 3.0, refer to the user's guide.
* When installing a new version of the product, the installer program will
automatically replace the OpenSSL 1.1.1 library files with the OpenSSL 3.0
library files in the install directory, which will impact all the DataDirect
ODBC drivers installed on a machine. Therefore:
- If you are using multiple 7.1 drivers, upgrade all your drivers to the latest
version.
- If you are using both 8.0 and 7.1 versions of the driver, copy the xxtls28.dll
file to a different location before installing a new version of the 7.1 driver.
Copy it back to the install directory once the installation is complete.
End of Support for OpenSSL 1.1.1
--------------------------------
The product no longer includes version 1.1.1 of the OpenSSL library.
The library will reach the end of its product life cycle in September 2023
and will not receive any security updates after that. Note that continuing
to use the library after September 2023 can potentially expose you to
security vulnerabilities.
Note: As a result of this change, when installing a new version of the product,
the installer program will automatically remove version 1.1.1 of the library
from the install directory, which will impact all the DataDirect ODBC drivers
installed on a machine.
Installer Upgrade
-----------------
The installer program has been enhanced to use a more modern and
secure technology. As a result of this enhancement:
* The default installation location has been changed to:
- For the 32-bit driver on a 64-bit system:
C:\Program Files (86)\Progress\DataDirect\ODBC
- For all other installations:
C:\Program Files\Progress\DataDirect\ODBC
* The new installer program does not support upgrading installations
made with earlier versions of the installer. You will need to
uninstall the existing installation and reinstall with the new
installer to resume upgrades in the same directory.
* The existing data sources cannot be used until they are
updated to point to the new installation location. To learn
how to update them, refer to the best practices documented
at https://community.progress.com/s/.
* License keys you have used for the retired 7.1 installer cannot
be used with the new installer. Request new keys by either
contacting the Progress DataDirect Technical Support team or visiting
https://www.progress.com/datadirect-connectors/request-upgrade.
End of Support for OpenSSL 1.0.2
--------------------------------
The product no longer includes version 1.0.2 of the OpenSSL library.
The library has reached the end of its product life cycle and is not
receiving security updates anymore. Note that continuing to use the
library could potentially expose you to security vulnerabilities.
Note: As a result of this change, when installing a new version of the
driver, the installer program will automatically remove version 1.0.2
of the library from the install directory.
Documentation
-------------
Any product package made available after February 9, 2021 will not include the
HTML help system or user's guide PDF. The Progress DataDirect Connect Series for
ODBC documentation set is available via product and data source tiles from the
Progress Information Hub:
https://docs.progress.com
While the product packages will not include these documentation items, the
installation Help directory will provide an HTML redirect for direct access
to the HTML help.
Timestamp Logging in Packet Logs
--------------------------------
The drivers has 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.
Allowed OpenSSL Versions Connection Option
------------------------------------------
* The new AllowedOpenSSLVersions option determines which version of the OpenSSL
library file the driver uses for data encryption when multiple versions are
installed with the product. For example, when specifying a value of 1.1.1
(AllowedOpenSSLVersions=1.1.1), the driver uses the 1.1.1 version of the
library stored in the /lib subdirectory. Refer to the user's guide for more
information.
Support for Windows Platforms
-----------------------------
The following Windows platforms have reached the end of their product
lifecycle and are no longer supported by the drivers:
* Windows 8.0 (versions 8.1 and higher are still supported)
* Windows Vista (all versions)
* Windows XP (all versions)
* Windows Server 2003 (all versions)
Batch Mechanism Connection Option
---------------------------------
The driver has been enhanced with the new Batch Mechanism (BatchMechanism)
connection option, which specifies the preferred mechanism for executing
batch insert operations. By setting Batch Mechanism to 2 (MultiRowInsert) or
3 (Copy), the driver can achieve substantial performance gains when
performing batch inserts. The default setting is BatchMechanism=1
(SingleRowInsert).
Citext, Float, and Tinyint Data Types
-------------------------------------
The driver has been enhanced to support the following data types: Citext,
Float, and Tinyint.
Power BI connector
------------------
A Power BI connector is now included with the product package. You can use
this connector to access your Greenplum data with Power BI. Refer to the
user's guide for details.
Changes for 7.1.6 GA
CryptoLibName and SSLLibName Connection Options
-----------------------------------------------
The new CryptoLibName and SSLLibName connection options allow you to
designate the OpenSSL libraries used when SSL is enabled.
Support for Kerberos Authentication
-----------------------------------
Support for Kerberos Authentication, which can be configured using the
following new connection options:
* Authentication Method
* GSS Client Name
* Service Principal Name
* User Name
Notes, Known Issues, and Restrictions
Power BI Connectors
-------------------
Branding for Power BI connectors is not currently supported.
Specifying values for the same connection option multiple times
---------------------------------------------------------------
The driver does not support specifying values for the same connection
option multiple times in a connection string or DSN. If a value is
specified using the same attribute multiple times or using both
long and short attributes, the connection may fail or the driver may
not behave as intended.
Disabling Diffie-Hellman Cipher Suites
--------------------------------------
If your database has not been fixed to address the Logjam vulnerability, you
can still use the most recent version of the OpenSSL Library by disabling the
Diffie-Hellman cipher suites. To disable the Diffie-Hellman cipher suites,
specify the following value for the undocumented CipherList connection option:
CipherList=DEFAULT:-DH
If you have already specified a value for CipherList, add the following to the
existing value:
:-DH
The option-value pair for undocumented options can be specified in the
connection string or the Extended Options field of the GUI. For
details, refer to "Configuring and Connecting to Data Sources" in the
individual driver chapters of the DATADIRECT CONNECT SERIES FOR ODBC
USER'S GUIDE.
126 Error When Modifying Data Sources on Windows 10
---------------------------------------------------
You may receive a 126 error when adding or configuring a data source stored
on a network location. This is caused by the settings of the User Account
Control (UAC) security feature on Windows 10. To work around this issue:
Important: Implementing this fix disables security safeguards that are designed
to protect your machine. Before starting, refer to the following Microsoft
documentation for potential risks associated with disabling the UAC feature:
http://windows.microsoft.com/en-us/
windows/what-are-user-account-control-settings
1. From the Start menu, type regedit in the search field; then, select regedit
from the results list. The Registry Editor window opens.
2. Navigate to the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
3. Right-click on the subkey; then, select New > DWORD Value.
4. Rename the new value EnableLinkedConnections.
5. Right-click EnableLinkedConnections, and then click Modify. The Edit DWORD
Value window opens.
6. In the Value data field, type 1. Click OK.
7. Close the Registry Editor; then, restart your computer.
For SSL Users
-------------
When trying to connect to a database using SSL encryption, you may
receive an error message similar to: "PRNG not seeded". This is because
certain versions of some operating systems do not generate truly random
numbers necessary for encryption. For more information about this error
and available patches, please refer to the Web site:
http://www.openssl.org/support/faq.html#USER1
ODBC Development on Windows Platforms
--------------------------------------
Please read the notices.txt file in the installation directory for
licensing information regarding the ODBC Core Components. Contact your
Progress DataDirect representative if you have any questions.
SQLColAttribute(s)
------------------
The column attributes 1001 and 1002, which were assigned as DataDirect-
specific attributes, were inadvertently used as system attributes by
the Microsoft 3.0 ODBC implementation. Applications using those
attributes must now use 1901 and 1902, respectively.
SQL_C_NUMERIC
-------------
Because of inconsistencies in the ODBC specification, users attempting
to use SQL_C_NUMERIC parameters must set the precision and scale values
of the corresponding structure and the descriptor fields in the
Application Parameter Descriptor.
For Developers Using IIS
------------------------
One of the most common connectivity issues encountered while using IIS
(Microsoft's Internet Information Server) concerns the use and settings
of the account permissions. If you encounter problems using DataDirect
drivers with an IIS server, refer to KnowledgeBase document number 4274
on the Progress DataDirect web site:
http://knowledgebase.datadirect.com.
For Microsoft Access Users
--------------------------
Some SQL implementations, such as PROGRESS, do not allow queries to
contain the COUNT function without the DISTINCT set quantifier. For
example, "SELECT COUNT(empid) FROM employees" is not a valid SQL query
for PROGRESS. This type of query can be generated using Microsoft
Access and results in an error.
Driver WorkAround Options
Progress DataDirect has included non-standard connection options (workarounds)
for the driver that enable you to take full advantage of packaged ODBC-enabled
applications requiring non-standard or extended behavior. Refer to the chapter
"WorkAround options" in THE PROGRESS DATADIRECT FOR ODBC DRIVERS REFERENCE for
a description of these options.
Documentation
PROGRESS DATADIRECT CONNECT SERIES FOR ODBC DOCUMENTATION SET
-------------------------------------------------------------
The Progress DataDirect Connect Series for ODBC documentation set is available
via product and data source tiles from the Progress Information Hub:
https://docs.progress.com
You can access the online help system directly via the HTML redirect in the
installation Help directory.
