Changes Since 7.1.6 GA
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) for AIX Platforms
--------------------------------------------
For AIX platforms, 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 AIX platforms:
* For the 32-bit driver: From libivicu28.a to libivicu.a
* For the 64-bit driver: From libddicu28.a to libddicu.a
Notes:
* This upgrade does not apply to the other UNIX platforms.
* This upgrade is available starting in build 08.02.1072 of the ICU
library files.
* libivicu27.a (32-bit) and libddicu27.a (64-bit) will continue to
be included in the product package to support driver functionality.
Driver Manager Upgrade (8.0)
----------------------------
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:
- For the 32-bit driver: From ivtrc27.so to ivtrc28.so
- For the 64-bit driver: From ddtrc27.so to ddtrc28.so
Note: libivicu27.so (32-bit) and libddicu27.so (64-bit) will continue to
be included in the product package to support driver functionality.
The Driver Manager build included with the product is 08.02.1997 (U1987).
ICU Library Upgrade (74.1) for Linux Platforms
----------------------------------------------
For Linux platforms, the ICU library files that are installed with
the product have been upgraded to version 74.1. As a part of this upgrade,
the following ICU library files have been added to the product package:
libivicu.so (32-bit) and libddicu.so (64-bit).
This upgrade is available starting in build 08.02.0965 of the ICU library
files.
Password Encryption Tool
------------------------
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.
ODBC Cursor Library
-------------------
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.
Linux ODBC Administrator
------------------------
Support has ended for the DataDirect ODBC Data Source Administrator for Linux.
As a result, the Linux ODBC Administrator will no longer be installed with the
product. In addition, to avoid exposure to potential security vulnerabilities,
the installer program will remove Linux ODBC Administrator files from
existing installation directories during updates and new product installations.
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:
- On AIX: libivopenssl30.a (32-bit) and libddopenssl30.a (64-bit)
- On other platforms: ivopenssl30.so [.sl] (32-bit) and ddopenssl30.so (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.so
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:
/opt/Progress/DataDirect/ODBC_32Bit
- For the 64-bit driver:
/opt/Progress/DataDirect/ODBC_64Bit
* 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 driver 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.
Setting Unicode Encoding Type for Connections
---------------------------------------------
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.
AllowedOpenSSLVersions
----------------------
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.
BatchMechanism Connection Option
--------------------------------
The driver has been enhanced with the new 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.
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:
* AuthenticationMethod
* GSSClient
* ProxyUser
* ServicePrincipalName
Configuring Data Sources
Data sources are stored in the system information file (typically,
odbc.ini). For details on configuring this file, see the DATADIRECT
CONNECT SERIES FOR ODBC USER'S GUIDE.
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.
Notes, Known Issues, and Restrictions
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
odbc.ini, 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.
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.
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
SSL and the Linux ODBC Administrator
-----------------------------------
The Linux ODBC Administrator does not correctly save the encrypted
truststore password, keystore password, and key password in the
odbc.ini file when specifying them on the Security tab of the driver
Setup dialog boxes. To set these connection options, you must edit the
odbc.ini file directly and use the appropriate connection string
attributes to store these passwords in the file. You cannot use the
driver Setup dialog boxes. See the DATADIRECT CONNECT SERIES FOR ODBC
USER'S GUIDE for details about the Security tabs and the odbc.ini file.
ODBC Development on UNIX and Linux Platforms
--------------------------------------------
All of the Release 7.1 Core Components (header files, etc.) needed for
development of ODBC applications on UNIX and Linux are installed into
the /include directory created by the product installer.
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.
Developers using programming languages other than C++:
The DataDirect ODBC Driver Manager is a C++ shared library. The ODBC
Driver Manager can be used with any language that supports loading a
C++ shared library; however, if you are using a programming language
other than C++, you must take additional steps to ensure that the C++
libraries are initialized properly when loaded. If you are not using
C++, consult your compiler documentation for instructions on using C++
shared libraries with your application.
LANG Environment Setting on UNIX and Linux Platforms
----------------------------------------------------
A default installation of the product on UNIX and Linux assumes that
the value of the LANG environment setting is en_US. If your locale is
not set to en_US, the drivers may not return error messages properly.
In this case, you must create a symbolic link in the
<Install_Dir>/locale directory that has the same value as the LANG
environment setting. This link must point to the
<Install_Dir>/locale/en_US directory.
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.
