从上面的日志可以看出应该是两个节点的端口不匹配导致的问题，手动创建ONS服务使用的是6251端口，使用vipca创建的可能不是6251端口，所以导致两边的端口不匹配。

一.onsctl工具

下面是onsctl工具的帮助信息：

[root@rhel1 bin]#./onsctl

usage: ./onsctl start|stop|ping|reconfig|debug

start                            - Start opmn only.

stop                             - Stop ons daemon

ping                             - Test to see if ons daemon is running

debug                            - Display debug information for the ons daemon

reconfig                         - Reload the ons configuration

help                             - Print a short syntax description (this).

detailed                         - Print a verbose syntax description.

[root@rhel1 bin]#./onsctl detailed

usage: ./onsctl start|stop|ping|reconfig|debug

start

Start ons daemon

stop

Shutdown ons daemon

reconfig

Trigger ons to re-read it's configuration files.

ping

Test to see if ons daemon is alive

debug

Display debug information about the ons daemon

help

Print a short syntax description.

detailed

Print a verbose syntax description (this message).

在第一个节点执行onsctl ping命令：

[root@rhel1 bin]#./onsctl ping

Number of configuration nodes retrieved: 2

0: {node = rhel, port = 6251}

GETHOSTBYNAME(rhel): 2

Adding remote host rhel:6251

GETHOSTBYNAME(rhel): 2

1: {node = rhel2, port = 6251}

Adding remote host rhel2:6251

ons is running ...

ons在第一个节点已经处于运行状态。

在第二个节点执行onsctl ping命令：

[root@rhel2 bin]#./onsctl ping

Number of configuration nodes retrieved: 2

0: {node = rhel, port = 6251}

GETHOSTBYNAME(rhel): 2

Adding remote host rhel:6251

GETHOSTBYNAME(rhel): 2

1: {node = rhel2, port = 6251}

Remote port for local node in local config does not match that from OCR.

ons is not running ...

发现第二个节点ons因为端口与第一个节点不匹配的原因而没有启动。

二.查看节点进程：

查看第一个节点的ons进程：

[root@rhel1 bin]#ps -ef | grep ons

root      2412     1  0 16:47 ?        00:00:00 sendmail: accepting connections

oracle   13513     1  0 17:17 ?        00:00:00 /u01/app/oracle/crs/opmn/bin/ons -d

oracle   13515 13513  0 17:17 ?        00:00:00 /u01/app/oracle/crs/opmn/bin/ons -d

root     15646  3340  0 17:22 pts/0    00:00:00 grep ons

查看第二个节点的osn进程：

[root@rhel2 bin]#ps -ef | grep ons

root      2400     1  0 16:45 ?        00:00:00 sendmail: accepting connections

root     13847  3546  0 17:22 pts/0    00:00:00 grep ons

三.ONS配置文件

执行find命令找到了ons的配置文件，如下：

./opmn/conf/ons.config.tmp

./opmn/conf/ons.config

./opmn/conf/ons.config.backup.10205

[root@rhel1 crs]#cat ./opmn/conf/ons.config

localport=6113

remoteport=6200

loglevel=3

useocr=on

显然配置文件中的端口与执行racgons配置的6251不匹配。

四.RACGONS工具

RACGONS的帮助信息如下：

[root@rhel1 bin]#./racgons

To add ONS daemons configuration:

./racgons.bin add_config hostname:port [hostname:port] ...

To remove ONS daemons configuration:

./racgons.bin remove_config hostname[:port] [hostname:port] ...

在OCR中可能配置有两条ONS的信息，执行以下的命令删除原有的6251端口配置：

[root@rhel1 bin]#./racgons remove_config rhel:6251 rhel2:6251

racgons: Existing key value on rhel = 6251.

racgons: rhel:6251 removed from OCR.

racgons: Existing key value on rhel2 = 6251.

racgons: rhel2:6251 removed from OCR.

重新启动nodeapps：

[root@rhel1 bin]# ./srvctl start nodeapps -n rhel2

[root@rhel1 bin]# ./srvctl start nodeapps -n rhel1

查看两个节点的状态：

[root@rhel1 bin]#./crs_stat -t

Name           Type           Target    State     Host

------------------------------------------------------------

ora.rhel1.gsd  application    ONLINE    ONLINE    rhel1

ora.rhel1.ons  application    ONLINE    ONLINE    rhel1

ora.rhel1.vip  application    ONLINE    ONLINE    rhel1

ora.rhel2.ons  application    ONLINE    ONLINE    rhel2

ora.rhel2.vip  application    ONLINE    ONLINE    rhel2

恢复正常。
