Troubleshooting on message buffer

OVOW agent 与server之间进行消息的传递，牵涉到多方面的配置。如果使用 opcagt/opcragt查看 agent状态发现有message buffering状况发生，可以尝试以下一些方法进行排错

1） 删除message queue

on the agent side.
1- stop the agent via "opcagt -stop"
2- delete msgagtq
3- restart the agent via "opcagt -start"

On the management server side, 
1- stop the OVOW services via "vpstat -3 -r stop"
2- remove the file “MessageQueue”
3- restart the OVOW services via "vpstat -3 -r start"

2） 设定 OPC_IP_ADDRESS

在Cluster或者其它有多个ip地址的情况下，agent可能会使用不正确的那个IP来发送message 到OVOW server, 所以 应该手动指定。

You have to insert in the opcinfo file of the agent the key word "OPC_IP_ADDRESS

.

另外，还可以用 ovconfget 来查看配置情况， ovconfchg 来修改配置。

3）配置trusted certificates for multiple management servers

1.On every management server, export the trusted certificate to a file using the following command:
ovcert -exporttrusted -ovrg server -file
The command generates a file with the name that you specify.
2.Copy each file to every other management server, and import each trusted certificate using the following command:
ovcert -importtrusted -ovrg server -file
3. run ovcert -updatetrusted
