Configures an ordered set of similar, redundant services. This is useful when hot standby or backup adaptation servers are available. adaptation_service_set set_name service_name1 service_name2 ... The named services are used in the set declaration order. The first applicable adaptation service from the set is used first. The next applicable service is tried if and only if the transaction with the previous service fails and the message waiting to be adapted is still intact. When adaptation starts, broken services are ignored as if they were not a part of the set. A broken service is a down optional service. The services in a set must be attached to the same vectoring point (e.g., pre-cache) and use the same adaptation method (e.g., REQMOD). If all services in a set are optional then adaptation failures are bypassable. If all services in the set are essential, then a transaction failure with one service may still be retried using another service from the set, but when all services fail, the master transaction fails as well. A set may contain a mix of optional and essential services, but that is likely to lead to surprising results because broken services become ignored (see above), making previously bypassable failures fatal. Technically, it is the bypassability of the last failed service that matters.
