This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-Connect-2.0.4-GA.html ________________________________________________________________________ INTRODUCTION The mxODBC Connect Database Interface for Python allows users to easily connect Python applications to all major databases on the market today in a highly portable, convenient and secure way. Python Database Connectivity the Easy Way ----------------------------------------- Unlike our mxODBC Python extension, mxODBC Connect is designed as client-server application, so you no longer need to find production quality ODBC drivers for all the platforms you target with your Python application. Instead you use an easy to install royalty-free Python client library which connects directly to the mxODBC Connect database server over the network. This makes mxODBC Connect a great basis for writing cross-platform multi-tier database applications and utilities in Python, especially if you run applications that need to communicate with databases such as MS SQL Server and MS Access, Oracle Database, IBM DB2 and Informix, Sybase ASE and Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many more, that run on Windows or Linux machines. Ideal for Database Driven Client Applications --------------------------------------------- By removing the need to install and configure ODBC drivers on the client side and dealing with complicated network setups for each set of drivers, mxODBC Connect greatly simplifies deployment of database driven client applications, while at the same time making the network communication between client and database server more efficient and more secure. For more information, please have a look at the mxODBC Connect product page, in particular, the full list of available features. For more information, please see the product page: http://www.egenix.com/products/python/mxODBCConnect/ ________________________________________________________________________ NEWS The 2.0.4 release of mxODBC Connect includes the following enhancements and fixes: Security Enhancements --------------------- * Upgraded client and server to the most recent eGenix pyOpenSSL Distribution 0.13.3.1.0.1.6. See http://egenix.com/go52 for details. * Authentication errors are now reported with the SYSTEM_ERROR log level, making them visible using the default server side log level setting. Server Enhancements ------------------- * Updated the server to use eGenix mxODBC 3.2.3 for database connectivity. See http://egenix.com/go45 for details. * Added new server connection configuration setting connection_cursortype which allows modifying the default cursor type (using the new connection.cursortype attribute value; see http://egenix.com/go42) without having to modify the client side applications. The setting can be applied on a per connection basis for enhanced flexibility. * The mxODBC DataDirect subpackage is now built against the current DataDirect ODBC manager version 7.1.2. Client Enhancements ------------------- * Fixed a problem with the .warningformat attribute not working as expected on cursors and connections. Performance Enhancements ------------------------ * MS SQL Server performance can be much enhanced, and increased to levels beyond that of mxODBC Connect 2.0.2 and previous releases, by adjusting the default cursor type to forward-only cursors instead of static cursors. mxODBC Connect 2.0.4 makes this possible without having to change client side applications by modifying the server-config.ini file as follows: [Connection_Example] ... # Use the faster forward-only cursors on this connection connection_cursortype = SQL.CURSOR_FORWARD_ONLY The performance increase compared to mxODBC Connect 2.0.2 is enormous: from 2-3x faster executes/fetches for average queries, up to 300x faster for simple cases. In mxODBC Connect 2.1, we will switch to using forward-only cursors per default for all database backends. * IBM DB2 can benefit from the same performance enhancements using forward-only cursors. The effect is a lot smaller, but still noticeable: up to 2x faster executes/fetches with forward-only cursors, compared to mxODBC Connect 2.0.2. For the full set of changes, please check the mxODBC Connect change log: http://www.egenix.com/products/python/mxODBCConnect/changelog.html mxODBC Connect 2.0 Highlights ----------------------------- mxODBC Connect 2.0 was released on 2012-08-20. These are the most important highlights: * mxODBC Connect Server now uses mxODBC 3.2 internally and makes its API available in the mxODBC Connect Client. This is a major step forward from the mxODBC 3.0 version used in mxODBC Connect Server 1.0. * We've added native Windows x64 builds. * mxODBC Connect Client now integrates directly with gevent, allowing client applications to run asynchronous tasks while performing remote database queries.
