[oracle@sh ~]$ lsnrctl status

TNS-01189: The listener could not authenticate the user

-- 這個問題基本2個原因?qū)е?  

1,  /etc/hosts 文件中的 ip和主機名不一致

2, listener.ora 中監(jiān)聽主機非當前主機.

通過檢查, 是 listener.ora  監(jiān)聽主機填寫錯誤錯誤

LISTENER =  (DESCRIPTION_LIST =    (DESCRIPTION =      (ADDRESS = (PROTOCOL = TCP)(HOST = sh)(PORT = 1521))    )    (DESCRIPTION =      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))    )  )

修改為當前主機名后,重啟監(jiān)聽恢復(fù)正常.
