Abstract
A method, system, and program product for allocating a port for a connection by an application instance on a computer system is provided. The application instances used the port and a shared network address to connect to one or more application instances accessing the shared network address. A distributing stack creates at least one common table of available ports. Each table is associated with a different unique shared network address. When a request is received for a port to assign the shared network address, the distributing stack allocates a set of available ports. When a termination message is received, the distributing stack updates the common table of available ports associated with the shared network address. When a transfer from the distributing stack to a backup distributing stack is made, ownership of the common table of available ports is transferred to the backup distributing stack.
