Abstract: A computer-implemented method according to one embodiment includes receiving a request to add a generic volume entry to a generic volume element list, storing the generic volume entry in the generic volume element list in a SMS configuration in a SCDS, and building a volume list definition of the SMS configuration. A unit control block chain is parsed for determining additional specific volumes. It is determined whether a specific volume found in the parsing was not used in the building. In response to a determination that the specific volume found in the parsing was not used in the building, it is determined, for the specific volume found in the parsing, whether at least one predetermined condition is met. The specific volume found in the parsing is added to the volume list definition in response to a determination that the at least one predetermined condition is met.

Abstract: A computer system includes at least a server procedure and a client processor. The client processor includes plural applications which issue requests for execution of server procedures. A queue is present in the client processor and lists the requests. The client processor also includes plural input/output procedures which enable dispatch of requests to the server procedure. The client processor operates in conjunction with the I/O procedures, removes a request from the queue, and dispatches the request to the server procedure. The processor responds to occurrence of a time-out, with no response being received from the server procedure, to place the current request at the beginning of the queue so as to enable the I/O procedure to service a further request from the queue.
