In MVS, a subsystem that receives jobs into the system, converts them to internal format, selects them for execution, processes their output, and purges them from the system. In an installation with more than one processor, each JES2 processor independently controls its job input, scheduling, and output processing.; 操作系統(tǒng)MVS中的一種子系統(tǒng),負(fù)責(zé)接收輸入系統(tǒng)的作業(yè),把它們轉(zhuǎn)換成內(nèi)部格式,選擇符 合條件的作業(yè)去運(yùn)行,然后處理其輸出,最后把不再有用的作業(yè)從系統(tǒng)中刪去。對(duì)于具有多 個(gè)處理機(jī)的計(jì)算中心而言,其中的每臺(tái)JES2處理機(jī)可以獨(dú)立地管理(即控制)其作業(yè)的輸入、 調(diào)度和輸出處理。
