1. A VSAM keysequenced data set at the host processor, used to contain all of the IBMsupplied subsystem controller data, certain control records, and user programs for subsystem controllers connected to the host processor. It also contains the control records (SCDRs) that specify the configuration and options for individual store controllers.; 主處理機(jī)中的一種以關(guān)鍵字排序的虛擬存儲存取法(VSAM)數(shù)據(jù)集,通常包括所有IBM提供的子系統(tǒng)控制器數(shù)據(jù)、某些控制記錄以及連接到主處理機(jī)的子系統(tǒng)控制 器的用戶程序。它還包括為各個存儲控制器說明配置和選項(xiàng)的子系統(tǒng)控制定義記錄。 2. In DPCX, a library at the host system, created and maintained by subsystem support services, that provides services for subsystems such as creating and updating subsystem libraries, processing programs and data to be used by the subsystems, and transmitting the programs and data to communication controllers and programcontrolled terminals. | 在分布式處理控制執(zhí)行程序(DPCX)中,由子系統(tǒng)支持服務(wù)程序在主系統(tǒng)內(nèi)建立和維護(hù)的一種程序庫,為子系統(tǒng)提供有關(guān)服務(wù),如建立和更新子 系統(tǒng)庫、處理子系統(tǒng)將用的程序和數(shù)據(jù)、把程序和數(shù)據(jù)傳送到通信控制器及程序控制終端。
