问题1现象

数据导出脚本执行失败，报错如下

ORA-12537

 

到服务器上查看，报错：

[oracle@test ~]$ lsnrctl status

解决：

思路，报错提示地址已经使用，百度查找结果，大多都是hosts文件配置问题，但我的hosts文件正常的

最后真实原因是有其它监听已启用，kill掉重新注册监听

1）ps查看已有的监听并清除

$ ps -ef|grep LISTENER
oracle    1781  1373  0 11:38 pts/0    00:00:00 grep LISTENER
grid      5685     1  0  2018 ?        00:06:51 /grid/11.2.0/grid_1/bin/tnslsnr LISTENER_SCAN2 -inherit
grid      5687     1  0  2018 ?        00:09:32 /grid/11.2.0/grid_1/bin/tnslsnr LISTENER_SCAN3 -inherit
daemon   26031     1  0 11:10 ?        00:00:00 /grid/11.2.0/grid_1/bin/tnslsnr LISTENER -inherit

$ kill -9 5685 5687 26031

2）动态注册恢复监听状态

$ sqlplus / as sysdba

 问题二现象：

本以为可以连接了，然后执行远程登录测试，出现报错ORA-12502

C:\Users\Administrator>sqlplus user/passwd@hostname.:1521/sid

SQL*Plus: Release 11.2.0.1.0 Production on 星期二 4月 2 13:14:11 2019

ERROR:
ORA-12502: TNS: 监听程序没有从客户机收到 CONNECT_DATA

解决：

设置所有节点的LOCAL_LISTENER参数，即可解决。host为vip

SQL> show parameter local_listener;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
local_listener                       string
SQL> alter system set local_listener='(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.10.173)(PORT=1521))';

System altered.

SQL> show parameter local_listener;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
local_listener                       string      (ADDRESS=(PROTOCOL=tcp)(HOST=1
                                                 92.168.10.173)(PORT=1521))

 

成功远程登录，问题解决
