High Availability/Failover

For programs running or resident on backup machines, IBM defines 3 types of situations: "cold"; "warm"; and "hot". In the "cold" and "warm" situations, a separate license for the backup copy is normally not required, no additional charge applies, and IBM does not need to be notified. In a "hot" backup situation, the customer needs to acquire another license. All programs running in backup mode must be under the customer's control, even if running at another enterprise's location.

As a practice we have the following definitions and allowable actions concerning the copy of the program used for backup purposes:

- cold - a copy of the program may be stored for backup purposes on a machine as long as the program has not been started. There is no charge for this copy.

- warm - a copy of the program may reside for backup purposes on a machine and is started, but is "idling", and is not doing any work of any kind. There is no charge for this copy.

- hot - a copy of the program may reside for backup purposes on a machine, is started and is doing work. However, this program must be ordered. There is a charge for this copy.

"Doing Work" includes, for example, production, reporting, development, program maintenance, and testing. "Doing Work" does not include activities such as mirroring of transactions, updating of files, synchronization of programs, data or other resources (e.g., active linking with another machine, program, database or other resource, etc.).

The standby server should be licensed using the same metric as the production server, depending on how the production licenses are purchased.
