system is:
C:\Program Files (x86)\Progress\DataDirect\ODBC
* The default installation directory for all other installations is:
C:\Program Files\Progress\DataDirect\ODBC
Requirements
* The installer program requires a JVM that is Java SE 11 or higher, including
Oracle JDK, OpenJDK, and IBM SDK (Java) distributions.
* The driver requires the following runtime library:
Microsoft Visual C/C++ runtime version 14.40.33810 or higher
* IMPORTANT: You must have the Microsoft Data Access Components (MDAC)
installed to use this product.
- For 32-bit Windows systems, version 2.6 or higher is required.
- For 64-bit Windows systems, version 2.8 or higher is required.
Depending on the version of your Windows operating system, these
components may already be installed. You can download a utility that
determines whether MDAC is installed and its version from the following

Third-party Components Compatibility Matrix
For 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
Changes for 8.0.2 GA
Debugging Symbols
------------------
The product package now includes .pdb files. These files contain debugging
symbols that can be used for diagnosing and debugging issues in the driver.
SCRAM-SHA-256 Support
---------------------
The driver has been enhanced to support the SCRAM-SHA-256 password hashing
mechanism for user ID/password authentication. The SCRAM-SHA-256 mechanism
is supported with Greenplum server v6.21 and higher.
Available starting: Driver version 08.02.0369 (B3149, U3111)
Windows Runtime Version Upgrade
-------------------------------
The driver is 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
This upgrade is available starting in build 08.02.1072 of the ICU
library files.
TLSv1.3 Support
---------------
The driver has been enhanced to support the TLSv1.3 cryptographic protocol for
TLS encryption. You can configure the cryptographic protocols used by the
driver with the Crypto Protocol Version (CryptoProtocolVersion) option.
End of Support for TLSv1.1 and TLSv1.0
--------------------------------------
The TLSv1.1 and TLSv1.0 cryptographic protocols are now disabled by default
and have been removed as selectable options for the Crypto Protocol Version
(CryptoProtocolVersion) option on the Setup dialog. These protocols are no
longer considered secure and, therefore, are no longer recommended for use.
However, the driver still supports them for legacy servers that do not
support the TLSv1.3 or TLS1.2 protocols.
Proxy Server Support
--------------------
The driver has been enhanced to support connecting to a proxy server through an
HTTP connection. HTTP proxy support is configurable with five new connection
options: Proxy Host, Proxy Mode, Proxy Password, Proxy Port, and Proxy User.
Refer to the user's guide for details.
Default Value for Batch Mechanism
----------------------------------
The default value for the Batch Mechanism (BatchMechanism) connection option has
been changed to 3 (Copy).
Default Values for Unbounded Numeric Precision and Unbounded Numeric Scale
--------------------------------------------------------------------------
The default values for the Unbounded Numeric Precision (UnboundedNumericPrecision)
and Unbounded Numeric Scale (UnboundedNumericScale) options have been changed to
-1.
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 8.0 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 xxtls27.dll
file to a different location before installing a new version of the 8.0 driver.
Copy it back to the install directory once the installation is complete.
Deprecation of the Allowed OpenSSL Versions Connection Option
--------------------------------------------------------------
The Allowed OpenSSL Versions (AllowedOpenSSLVersions) connection option has
been deprecated as the driver currently supports only version 3.0 of the
OpenSSL library.
Support for Windows Certificate Store
-------------------------------------
The driver has been enhanced to support the Windows certificate store for
TLS/SSL server authentication.
Support for TLS/SSL Server Authentication in a Serverless Environment
---------------------------------------------------------------------
The driver has been enhanced to support TLS/SSL server authentication for the
applications deployed in a server-less environment. The driver stores the
TLS/SSL certificates in memory and lets applications use TLS/SSL server
authentication without storing the truststore file on the disk. To use this
enhancement, specify the content of the certificate in the updated Trust Store
(Truststore) connection option or the new SQL_COPT_INMEMORY_TRUSTSTORECERT
pre-connection attribute.
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.
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=3
(Copy).
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.
Notes, Known Problems, and Restrictions
The following are notes, known problems, or restrictions with
Release 8.0.2 of the driver.
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.
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.
Upgrading from an Evaluation to a Licensed Installation
-------------------------------------------------------
If you have installed an evaluation copy of the drivers and want to
upgrade to a licensed version, you must use the Modify option of the
installation program. Refer to the installation guide for details.
Installing and Removing Default Data Sources
--------------------------------------------
When you first install a driver, you are given the option to install a
default data source for that driver. We recommend that you install
default data sources when you first install the drivers. If you do not
install the default data source at this time, you will be unable to
install a default data source for this driver later. To install a
default data source for a driver after the initial installation, you
must uninstall the driver and then reinstall it.
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
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 drivers 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 DATADIRECT CONNECT
SERIES FOR ODBC REFERENCE for a description of these options.
