ABSTRACT:
A determination is made whether a first application server of a group of N application servers, N being at least two, is a coordinator of the group. Responsive to determining that the first application server is the coordinator of the group, a connection to a billing system is established, via a terminal server, by the first application server. A determination is made whether a second application server of the group of N application servers is the coordinator of the group. Responsive to determining that the second application server is not the coordinator of the group, a periodic check is made whether the second application server of the group of N application servers is the coordinator of the group. The second application server may later be determined to be the coordinator of the group, when the first server experiences difficulty. Once it is determined that the second application server now is the coordinator of the group, a connection is established to the billing system, via the terminal server, by the second application server.
