Abstract
A method is disclosed for providing distributed transaction support functionality using JDBC 1.0 drivers. Instead of creating a new physical database connection for each connection request, an interface driver internally maintains a mapping in a table between a global transaction identifier and the physical database connection. Even if an application requests multiple connections to the same database for the same transaction, all database access through those connections would actually be redirected to the same physical database connection as maintained in the table. This allows all the work to be coordinated under the same transaction. Thus, limited JDBC 2.0 Standard Extension driver compatibility is achieved using standard JDBC 1.0 drivers.
