TNS-01106: Listener using listener name LISTENER has already been started

-- 通过ps 命令没有发现监听的进程

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=wh)(PORT=1521)))

TNS-01189: The listener could not authenticate the user

-- 这个问题基本2个原因导致,

1, /etc/hosts 文件中的 ip和主机名不一致

2, listener.ora 中监听主机非当前主机.

通过检查, 是 listener.ora 监听主机填写错误错误

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

修改为当前主机名后,重启监听恢复正常.
