listener TNS-01189 问题

-- 启动监听,提示已经启动.

[Oracle@sh ~]$ lsnrctl startLSNRCTL for linux: Version 12.1.0.2.0 - PRoduction on 06-FEB-2017 15:30:14Copyright (c) 1991, 2014, Oracle.  All rights reserved.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

[root@sh ~]# ps -ef | grep -i tnsroot        36     2  0 Jan26 ?        00:00:00 [netns]root     14995 14824  0 15:30 pts/1    00:00:00 grep -i tns

-- 查看监听状态,报错; TNS-01189

[oracle@sh ~]$ lsnrctl status

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.
