Oracle 11g RAC 监听日常管理

需要必须掌握的命令，上周遇到了一个小问题，就是需要重启数据库监听，有的同学竟然使用oracle用户重启监听，原理就搞错了怎么行。以下操作都需要再grid用户下进行操作。

1、查看监听状态

<roidb2:+ASM2:/home/grid>$srvctl status listener
Listener LISTENER is enabled
Listener LISTENER is running on node(s): roidb1,roidb2
<roidb2:+ASM2:/home/grid>$srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node roidb2
<roidb2:+ASM2:/home/grid>$

2、关闭监听

<roidb2:+ASM2:/home/grid>$srvctl stop listener -n roidb1
<roidb2:+ASM2:/home/grid>$srvctl status listener -n roidb1
Listener LISTENER is enabled on node(s): roidb1
Listener LISTENER is not running on node(s): roidb1
<roidb2:+ASM2:/home/grid>$
<roidb2:+ASM2:/home/grid>$srvctl stop scan_listener
<roidb2:+ASM2:/home/grid>$srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is not running
<roidb2:+ASM2:/home/grid>$

3、启动监听

<roidb2:+ASM2:/home/grid>$srvctl status listener
Listener LISTENER is enabled
Listener LISTENER is running on node(s): roidb1,roidb2
<roidb2:+ASM2:/home/grid>$srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node roidb2
<roidb2:+ASM2:/home/grid>$
