为什么会存在一个监听在rac-two上无法注册呢？
查看该节点监听：
[grid@rac-two admin]$ ps -ef | grep LISTENER grid 6120 1 0 17:02 00:00:00 /u01/app/11.2.0/grid/bin/tnslsnr LISTENER -inherit grid 8511 1 0 18:28 00:00:00 /u01/app/11.2.0/grid/bin/tnslsnr LISTENER_SCAN1 -inherit grid 11010 1 0 18:42 00:00:00 /u01/app/11.2.0/grid/bin/tnslsnr LISTENER -inherit grid 11246 9191 0 18:44 pts/1 00:00:00 grep LISTENER
原来是启动了两个，全部停掉再次重启：
