rac1-> srvctl status instance -d devdb -i devdb1
Instance devdb1 is not running on node rac1
rac1-> srvctl status instance -d devdb -i devdb2
Instance devdb2 is not running on node rac2
rac1-> srvctl status nodeapps -n rac1
VIP is running on node: rac1
GSD is not running on node: rac1
Listener is not running on node: rac1
ONS daemon is not running on node: rac1
rac1-> srvctl status nodeapps -n rac2
VIP is running on node: rac2
GSD is not running on node: rac2
Listener is not running on node: rac2
ONS daemon is not running on node: rac2

解决方法：

rac安装完成重启后，GSD,LISTENER,ONS服务is not running问题解决

rac安装完成重启后，相关服务启动不正常如下：

[oracle@rac1 ~]$ srvctl status nodeapps -n rac1
VIP is running on node: rac1
GSD is not running on node: rac1
Listener is not running on node: rac1
ONS daemon is not running on node: rac1

[oracle@rac1 ~]$ crs_stat -t

解决方法：

1，在各节点上分别:

# /etc/init.d/oracleasm enable

#/etc/init.d/oracleasm scandisks

2，主节点上运行：

#su – oracle

$crs_stop -all

$srvctl stop nodeapps -n rac1

$srvctl stop nodeapps -n rac2

$srvctl start nodeapps -n rac1

$srvctl start nodeapps -n rac2

$crs_start -all

$srvctl start database -d devdb

注：如果#/etc/init.d/oracleasm listdisks能正常显示的话，第1步可以忽略。

经测试上文可用
