摘要:
A computing system is configured to maintain equivalency of independent queues located in different coupling facilities. The computer system includes a first coupling facility and a second coupling facility. The first coupling facility receives a plurality of different commands instructing the first coupling facility to load data into a first structure. The first coupling facility generates a first command data block including first data corresponding to a received first command and a first sequence value indicating a sequence at which the first data was loaded into the first structure with respect to remaining data corresponding to the plurality of commands. A second coupling facility includes a second structure and a second queue. The second coupling facility receives the first command data block from a first queue of the first coupling facility and loads the first data from the second queue into the second structure based on the first sequence value.
