Note - This upgrade is available starting in build 08.02.1072 of the ICU
library files.
* Linux platforms
- 32-bit product package: From libivicu28.so to libivicu.so
- 64-bit product package: From libddicu28.so to libddicu.so
Note - This upgrade is available starting in build 08.02.0965 of the ICU
library files.
* Solaris platforms (Sparc and Solaris X)
- 32-bit product package: From libivicu28.so to libivicu.so
- 64-bit product package: From libddicu28.so to libddicu.so
Note - This upgrade is available starting in build 08.02.1799 of the ICU
library files.
* Limited availability platforms (Linux PPC, Linux z/OS, and IBM Power 8)
- 64-bit product package: From libddicu28.so to libddicu.so
Note - This upgrade is available starting in build 08.02.1799 of the ICU
library files.
As part of the ICU 74.1 upgrade, the complier and runtime versions for the
driver have been changed to the following:
* For AIX platforms, the compiler version has been upgraded to xlclang++ 16.1.
As a result, you must have C/C++ runtime libraries of 16.1 or higher on
your machine.
* For Linux platforms, the compiler version has been upgraded to GCC 7.3.1.
As a result, you must have C/C++ runtime libraries of GCC 2.12 or higher on
your machine.
* For Solaris platforms, the compiler version has been upgraded to Oracle
Developer Studio 12.6. As a result, you must have C/C++ runtime libraries
of 12.6 or higher on your machine.
* For limited availability platforms such as Linux PPC (64-bit), Linux z/OS
(64-bit), and IBM Power 8 (64-bit), the compiler version has been upgraded to
GCC 7.3.1. As a result, you must have C/C++ runtime libraries of GCC 2.17 or
higher on your machine.
Debugging Symbols
-----------------
The driver binaries now include debugging symbols that can be used for
diagnosing and debugging issues in 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.
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.
Changes to Installation of Non-Essential Components
-----------------------------------------------------
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 Informix Wire Protocol
driver:
* OpenSSL library files, such as ivopenssl30.so, ddopenssl30.so, fips.so,
and openssl.cnf.
* Curl library files, such as libivcurl28.so and libddcurl28.so.
If the files are not used by any other DataDirect driver on your machine, you
can safely remove them from existing product directories.
Release 8.0.2 Features
Enhancements
------------
* 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.
* 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.
* 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. Refer to the
user's guide for details.
Changed Behavior
----------------
* Support has been deprecated for the following versions of Informix:
- Informix 11.0 and higher
- Informix 10.0 and higher
- Informix 9.2 and higher
Configuring Data Sources
Data sources are stored in the system information file (typically,
odbc.ini). For details on configuring this file, see the PROGRESS DATADIRECT
FOR ODBC FOR INFORMIX WIRE PROTOCOL DRIVER 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.
Notes, Known Issues, and Restrictions
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.
ODBC Development on UNIX and Linux Platforms
--------------------------------------------
All of the Release 8.0 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.
