Selective tcp/ip stack reconfiguration

A computer program product comprising a computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:

• defining a plurality of recovery groups on each transmission control protocol/internet protocol (TCP/IP) stack in a cluster of servers, wherein the recovery group includes a service, one or more IP addresses associated with the service, a trigger condition, and a recovery action;
• monitoring each of the plurality of recovery groups for an occurrence of the trigger condition associated with the service;
• and
• in response to detecting the trigger condition, notifying a backup TCP/IP stack to automatically perform the recovery action defined for a failing recovery group on an owning TCP/IP stack, wherein only the failing recovery group is recovered and remaining recovery groups execute uninterrupted.

A computer system, comprising:

• one or more processors;
• and a computer-readable memory coupled to the one or more processors, the computer-readable memory comprising instructions for:
• defining a plurality of recovery groups on each transmission control protocol/internet protocol (TCP/IP) stack in a cluster of servers, wherein the recovery group includes a service, one or more IP addresses associated with the service, a trigger condition, and a recovery action;
• monitoring each of the plurality of recovery groups for an occurrence of the trigger condition associated with the service;
• and
• in response to detecting the trigger condition, notifying a backup TCP/IP stack to automatically perform the recovery action defined for a failing recovery group on an owning TCP/IP stack, wherein only the failing recovery group is recovered and remaining recovery groups execute uninterrupted.
