________________________________________________________________________ ANNOUNCEMENT mxODBC Zope/Plone Database Adapter Version 2.1.1 for Zope and the Plone CMS Available for Plone 4.0, 4.1 and 4.2, Zope 2.12 and 2.13, on Windows, Linux, Mac OS X, FreeBSD and other platforms This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-Zope-DA-2.1.1-GA.html ________________________________________________________________________ INTRODUCTION The eGenix mxODBC Zope DA allows you to easily connect your Zope or Plone CMS installation to just about any database backend on the market today, giving you the reliability of the commercially supported eGenix product mxODBC and the flexibility of the ODBC standard as middle-tier architecture. The mxODBC Zope Database Adapter is highly portable, just like Zope itself and provides a high performance interface to all your ODBC data sources, using a single well-supported interface on Windows, Linux, Mac OS X, FreeBSD and other platforms. This makes it ideal for deployment in ZEO Clusters and Zope hosting environments where stability and high performance are a top priority, establishing an excellent basis and scalable solution for your Plone CMS. Product page: http://www.egenix.com/products/zope/mxODBCZopeDA/ ________________________________________________________________________ NEWS We are pleased to announce the new version 2.1.1 of our mxODBC Zope/Plone Database Adapter product. Feature Enhancements -------------------- * Added a new connection property "ODBC cursor type" which allows easily adjusting the ODBC cursor type to be used for mxODBC Zope DA connection objects. This new property allows enhancing the performance of the adapter significantly, when using it with MS SQL Server or IBM DB2 database backends. Please see below for details. Driver Compatibility -------------------- * MS SQL Server performance can now be much enhanced, and increased to levels beyond that of previous mxODBC Zope DA releases, by adjusting the connection ODBC cursor type to "Forward only cursors". The performance increase compared to mxODBC Zope DA 2.1.0 is enormous: from 2-3x faster executes/fetches for average queries, up to 300x faster for simple cases. In mxODBC Zope DA 2.2, 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 Zope DA 2.1.0. * Added documentation to explain the different cursor types, compatibility with different database backends and effects on performance. Fixes ----- * Fixed the installation instructions to be more generic and easily adaptable to Plone and Zope installations on both Windows and Unix platforms. For the full set of changes please check the change log: http://www.egenix.com/products/zope/mxODBCZopeDA/changelog.html ________________________________________________________________________ FEATURES Version 2.1.0 of our mxODBC Zope/Plone Database Adapter product was released on 2012-09-18.
