Onsctl

Onsctl这个命令是用来管理ONS(Oracle Notification Service)是OracleClustser实现FAN Event Push模型的基础。

在RAC环境下,需要使用$CRS_HOME下的ONS,而不是$ORACLE_HOME下的ONS,这点需要注意。配置文件位于$CRS_HOME/opmn/conf/ons.config。

[oracle@felix2 conf]$ pwd

/u01/oracle/10.2.0/crs_1/opmn/conf

[oracle@felix2 conf]$ cat ons.config

localport=6113

remoteport=6200

loglevel=3

useocr=on

[oracle@felix2 conf]$ netstat -ano | grep 6200

tcp 0 0 0.0.0.0:6200 0.0.0.0:* LISTEN off (0.00/0/0)

tcp 0 0 192.168.10.102:8471 192.168.10.101:6200 ESTABLISHED off (0.00/0/0)

[oracle@felix2 conf]$ netstat -ano | grep 6113

tcp 0 0 127.0.0.1:6113 0.0.0.0:* LISTEN off (0.00/0/0)

[oracle@felix2 conf]$

配置ONS:

添加ONS:

[oracle@felix2 conf]$ racgons add_configfelix11:6200 felix22:6200

删除ONS:

[oracle@felix2 conf]$ racgons remove_configfelix11:6200 felix22:6200

[oracle@felix2 conf]$

Onsctl命令:

使用onsctl命令可以启动、停止、调试ONS,并重新载入配置文件,其命令格式如下:

注意:

ONS进程运行,并不一定代表ONS正常工作,需要使用ping命令来确认。

[oracle@felix2 conf]$ onsctl

usage: /u01/oracle/10.2.0/db_1/bin/onsctlstart|stop|ping|reconfig|debug

start - Start opmn only.

stop - Stop ons daemon

ping - Test to see ifons daemon is running

debug - Display debuginformation for the ons daemon

reconfig - Reload the onsconfiguration

help - Print a shortsyntax description (this).

detailed - Print a verbosesyntax description.

(1)在os级别查看进程

[oracle@felix2 conf]$ ps -ef | grep ons

root 2530 1 0 20:19 ? 00:00:00 sendmail: acceptingconnections

oracle 5223 1 0 20:22 ? 00:00:00/u01/oracle/10.2.0/crs_1/opmn/bin/ons -d

oracle 5224 5223 0 20:22 ? 00:00:00 /u01/oracle/10.2.0/crs_1/opmn/bin/ons-d

oracle 10833 29589 0 21:59 pts/2 00:00:00 grep ons

[oracle@felix2 conf]$

(2)确认ONS服务的状态

[oracle@felix2 conf]$ onsctl ping

Number of configuration nodes retrieved: 2

0: {node = felix1, port = 6200}

Adding remote host felix1:6200

1: {node = felix2, port = 6200}

Remote port for local node in local config doesnot match that from OCR.

ons is not running ...

[oracle@felix2 conf]$

从输出的信息课件,ONS服务是停止的。

(3)启动ONS服务

[oracle@felix2 conf]$ onsctl start

Number of configuration nodes retrieved: 2

0: {node = felix1, port = 6200}

Adding remote host felix1:6200

1: {node = felix2, port = 6200}
