This README file contains information not included in the PROGRESS DATADIRECT FOR ODBC FOR INFORMIX WIRE PROTOCOL DRIVER USER'S GUIDE. CONTENTS Driver Requirements Installation Directory Changes Since 8.0.2 GA Release 8.0.2 Features Driver WorkAround Options Notes, Known Problems, and Restrictions Documentation Installed Files for the 32-bit Driver Installed Files for the 64-bit Driver Driver Requirements * 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. 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 Changes Since 8.0.2 GA Driver Enhancements ------------------- * The default version of the OpenSSL library has been upgraded to version 1.1.1n, which fixes the following security vulnerabilities: - Infinite loop in BN_mod_sqrt() reachable when parsing certificates (CVE-2022-0778) - BN_mod_exp may produce incorrect results on MIPS (CVE-2021-4160) This upgrade is available in build 08.02.0216 of the following OpenSSL library files: ivtls28.dll (32-bit) and ddtls28.dll (64-bit). Version 1.1.1n also addresses vulnerabilities resolved by earlier versions of the library. For more information on OpenSSL vulnerabilities resolved by this upgrade, refer to the corresponding OpenSSL announcements at: https://www.openssl.org/news/vulnerabilities-1.1.1.html * The curl library files that are installed with the product have been upgraded to version 7.80.0, which fixes a number of potential security vulnerabilities. For more information on the vulnerabilities resolved by this enhancement, refer to: https://curl.haxx.se/docs/vulnerabilities.html. This upgrade is available starting in build 08.02.0278 of the curl library files. Release 8.0.2 Features Driver 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. 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 * The following Windows platforms have reached the end of their product lifecycle and are no longer supported by the driver: - Windows 8.0 (versions 8.1 and higher are still supported) - Windows Vista (all versions) - Windows XP (all versions) - Windows Server 2003 (all versions) 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. 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. ODBC Development on Windows Platforms -------------------------------------- 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. 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. Documentation PROGRESS DATADIRECT FOR ODBC FOR INFORMIX WIRE PROTOCOL DRIVER DOCUMENTATION SET --------------------------------------------------------------- The driver documentation set is available from the Progress Information Hub: https://docs.progress.com/category/datadirect-ibm-informix You can access the online help system directly via the HTML redirect in the installation Help directory.
