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 a Java Virtual Machine (JVM): Java SE, version 8 or
higher, including Oracle JDK, OpenJDK, IBM SDK (Java), or higher
LTS versions.
* 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

CVE-2022-41853 - Use of Externally-Controlled Input to Select Classes or Code
('Unsafe Reflection')
-----------------------------------------------------------------------------
Several Progress DataDirect ODBC drivers utilized a version of HyperSQL
Database that was vulnerable to remote code execution described in
CVE-2022-41853. All impacted drivers have been patched to fix this
vulnerability. For details on impacted drivers and fixed versions, refer to
the following KB article:
https://community.progress.com/s/article/DataDirect-ODBC-Critical-Security-
Bulletin-November-2022-CVE-2022-41853
Changed Behavior
----------------
* 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.
- To install the 32-bit drivers on 64-bit Windows platforms and start the SQL
engine service, the installer requires the 32-bit version of Java SE 11 or
higher installed on your machine and defined on your path.
* The installer program has been updated to no longer install common components
for drivers that do not use them. As a result, the installer program no longer
installs the following common components for the Aha! driver:
- OpenSSL library files, such as ivopenssl30.dll, ddopenssl30.dll, fips.dll, and
openssl.cnf.
- Curl library files, such as ivcurl28.dll and ddcurl28.dll.
If the files are not used by any other DataDirect driver on your machine, you
can safely remove them from existing product directories.
* The Server Name (ServerName) connection option has been renamed Host Name
(HostName). To support existing configurations, the ServerName attribute will
continue to be supported as an alias for the Host Name option.
Enhancements
------------
* 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.
* 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.
Release 8.0.0 Features
The Progress DataDirect for ODBC for Aha!(Aha! driver) is a driver that
supports SQL read-only access for ODBC applications to Aha! services. To
support SQL access to Aha! services, the driver creates a relational map of the
Aha! data model and translates SQL statements to Aha! REST API requests. In
addition, the driver employs a SQL engine component that provides support to
SQL constructs unavailable to Aha! services. This functionality offers a number
of advantages, including support for reporting data and metadata in a form ODBC
applications are ready to use.
Features:
* Supports SQL read-only access to Aha! endpoints
* The driver supports all ODBC Core and Level 1 functions and some Level 1 and
Level 2 features.
* Supports Aha! data types through data type inference.
* Supports Aha! custom fields, including many fields added
through third-party plug-ins
* Supports Basic, URL parameter (API key), and OAuth 2.0 authentication
* Supports SSL data encryption
* Supports the handling of large result sets with paging, and the
Fetch Size (FetchSize) Web Services Fetch Size (WSFetchSize) connection
options
* Includes the DataDirect ODBC Driver Configuration Manager for quick
configuration and testing of your driver. This Configuration Manager allows
you to:
- Configure data sources
- Generate and edit connection URLs
- Test connect data sources and connection URLs
- Execute SQL commands for testing
- Fetch OAuth tokens
- Access connection property descriptions and the full product
documentation
For details, see the "DataDirect ODBC Driver Configuration Manager" section.
DataDirect ODBC Driver Configuration Manager
The driver includes an enhanced version of the setup dialog, the DataDirect
ODBC Driver Configuration Manager, that allows you to generate and test
connection URLs and data sources that you can use with your application. You
can launch the Configuration Manager by opening the ODBC Administrator from
the Progress DataDirect program group and creating or configuring a data source
for the driver.
The Configuration Manager will open in your default web browser. For more
information, refer to the user's guide for your driver.
Notes, Known Problems, and Restrictions
The following are notes, known problems, and restrictions for the
8.0 release of the driver:
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.
Connection issues when specifying ExtendedOptions
-------------------------------------------------
When specifying a value for the Extended Options (ExtendedOptions) option in
the Configuration Manger, the driver currently adds the option and its value to
the Connection String field. However, the ExtendedOptions attribute is not
supported in Connection Strings; therefore, attempting to connect with the
generated connection string or executing a test connect with the configuration
manager will result in the an “Invalid attribute in the connection string: XO”
error.
To work around this issue, manually edit the connection string to remove
"ExtendedOptions=" from the connection string; then, specify the value of
ExtendOptions as semi-colon separated options in the string.
For example:
Driver=<driver_name>;HostName=<host_name>;ExtendedOptions=WorkArounds2=4096,
WorkArounds2=8192;
Becomes:
Driver=<driver_name>;HostName=<host_name>;WorkArounds2=4096;WorkArounds2=8192;
Out-of-memory Errors
--------------------
The driver has been designed to handle large result sets that result. However,
out-of-memory errors can still occur. The following items outline how to reduce
the likelihood of out-of-memory errors for your environment.
* Reduce Fetch Size (FetchSize) to reduce demands on memory. By lowering the
maximum number of rows as specified by Fetch Size, you lower the number of
rows the driver is required to process before returning data to the
application. Thus, you reduce demands on memory and decrease the likelihood
of out-of-memory errors.
* Decrease Result Memory Size (ResultMemorySize) until results are successfully
returned. Intermediate results larger than the value specified will be
written to disk as opposed to held in memory. When configured correctly, this
avoids memory limitations by not relying on memory to process larger
intermediate results. Be aware that while writing to disk reduces the risk of
out-of-memory errors, it also negatively impacts performance. For optimal
performance, decrease this value only to a size necessary to avoid errors. By
default, Result Memory Size is set to -1, which sets the maximum size of
intermediate results held in memory to a percentage of the max Java heap
size. If you received errors using the default configuration, use the max
Java heap size divided by 4 as a starting point when tuning this option.
* Increase the JVM heap size. By increasing the max Java heap size, you increase
the amount of data the driver can accumulate in memory and avoid
out-of-memory errors.
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 might be 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.
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
