Post-GA Product Announcements
The readme files will no longer be updated with product announcements and new
features after the General Availability (GA) of the product. For the latest
updates and enhancements, please refer to the release notes
(https://www.progress.com/datadirect-connectors/whats-new).
Installation Directory
* The default installation directory for the 32-bit driver on a 64-bit
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
Microsoft site:
http://msdn.microsoft.com/en-us/data/aa937730.aspx
You can also download MDAC from the same site.
Data Source and Platform Support
For the latest data source and platform support information, refer to the
Product Compatibility Guide:
https://docs.progress.com/bundle/datadirect-product-compatibility/resource/
datadirect-product-compatibility.pdf
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)
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.
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 using base version B0548 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.
Changes for 7.1.6 GA
No features introduced
Notes, Known Problems, and Restrictions
The following are notes, known problems, or restrictions with
Release 7.1.6 of the driver.
Text Driver Against Invalid Files
---------------------------------
Restriction: When the Text driver encounters an invalid file, you may
receive duplicate or multiple errors.
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.
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.
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.
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.
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.
