11、大文件時(shí)，提供事務(wù)完整性和基于日志的恢復(fù)。SFS 能夠提供數(shù)據(jù)處理與管理功能。數(shù)據(jù)處理功能提供訪問(wèn)和修改數(shù)據(jù)所必需的標(biāo)準(zhǔn)操作：讀、插入、更新、刪除、鎖定、解鎖等等。管理功能允許程序 查詢和修改 SFS 文件和卷、復(fù)制和刪除文件等等。SFS 使用 RPC 與其它服務(wù)器通信。132021/8/6142021/8/6XA接口是提供事務(wù)管理器和資源管理器之間互相調(diào)用的規(guī)范152021/8/6 CICS 區(qū)域處理一個(gè)或多個(gè)客戶請(qǐng)求的事務(wù)。通常，區(qū)域經(jīng)過(guò)訪問(wèn)數(shù)據(jù)庫(kù)、完成一些商業(yè)邏輯，然后才答復(fù)客戶。CICS 區(qū)域維護(hù)并使用一個(gè)多線程的進(jìn)程池，其中每個(gè)進(jìn)程提供一個(gè)處理事務(wù)的完整環(huán)境，這樣的進(jìn)程稱為應(yīng)用程序服
