1、超級(jí)用戶忘了密碼怎么辦？重起機(jī)器，自檢完成后，會(huì)出現(xiàn)這一行“Todiscontinue,pressanykeyin10seconds”,這時(shí)你按任意鍵，系統(tǒng)會(huì)中止啟動(dòng),進(jìn)入MainMenu.*鍵入“bo”,在系統(tǒng)詢問(wèn)“InteractwithIPL(YorN?)?”,輸入“y”。*在提示符ISL>后，輸入“hpux-is”,系統(tǒng)進(jìn)入單用戶狀態(tài)。*鍵入“passwd”,然后輸入新的密碼。鍵入“init3”,恢復(fù)系統(tǒng)正常運(yùn)行雙機(jī)熱備份常用命令:MC/LockManager(Multi-Computer/LockManager)是惠普公司推出專門(mén)用來(lái)保護(hù)關(guān)鍵業(yè)務(wù)應(yīng)用免遭軟、硬件故障影響的特殊應(yīng)用
2、軟件。使用MC/LockManager，多個(gè)節(jié)點(diǎn)(系統(tǒng))被組織成一個(gè)企業(yè)群集，為局域網(wǎng)(LAN)上的客戶機(jī)提供高可用性的服務(wù)。MC/Lock.Manager監(jiān)控程序監(jiān)控每一個(gè)節(jié)點(diǎn)的狀態(tài)，并且對(duì)出現(xiàn)的故障很快做出反應(yīng)，使對(duì)應(yīng)用程序的影響減小到最低。Abbreviations:CN=cluster_nameNN=node_namePN=package_nameExplainations:...=multipleoccurences
