Abstract: The invention provides reconnection of a client to a server in a transaction processing server cluster having a single address in order to resolve partially completed transactions, such as in doubt units-of-work. The method carried out at a client includes: establishing a connection with a first server in the server cluster and requesting units of work at the first server; detecting a failure of the connection to the first server; establishing a connection with a second server in the server cluster and requesting units of work at the second server; receiving a reconnection request from the first server, wherein the first server has unresolved units of work; terminating the connection with the second server including completing current units of work; and reconnecting with the first server and resynchronizing the unresolved units of work with the first server. The reconnection request may include a flag indicating that it is for a previously established connection and the server cluster to which the first server belongs.
