摘要
The environment of distributed transaction involves a number of resource managers,and we should do operations on resources such as connection and enlistment.during a transaction. Connecting to a resource will cost a lot of time,so connection pool mechanism is put into use on account of improving performance. And the resource connections in the connection pool need to be scheduled properly. In this paper,we specify how to implement resource enlistment and delistment in a distributed transaction,and present an algorithm of resource connection reusing and scheduling. Now the resource connection reusing and scheduling algorithm has been successfully employed in the implementation of the distributed transaction manager ISTX 1.0 system.
