This Bulletin identifies problems associated with attempting concurrent ODBC connections to multiple databases using proprietary ODBC drivers.
The Bulletin then identifies a potential solution to the problem using an ODBC Driver Manager. Although the Bulletin is written from the perspective of a TimesTen user, the concepts in the Bulletin may be applied to any application requiring concurrent connections to different vendors' datastores and databases via ODBC.
This Bulletin is intended for all application developers working who's applications require concurrent connections to different vendors' databases and datastores. It assumes a basic understanding of ODBC connectivity concepts, as well as C/C++ compilation and linking operations.
