Which ip hosts use in the mc/sg env?

[常有慈悲心]

I setup a mc/sg env and a package with oracle9i interation. The host1 ip is 192.1.1.1, host2 ip is 192.1.1.2 and the package ip is 192.1.1.7. the package run on the host1 mainly. But when package, running on the mc/sg env, ping the host3 beyond the firewall on the network, I find that the hosts1 ip used in the firewall log, not used the package ip.and the application on host3 only recieve the ip 192.1.1.7 not recieve other ip, so the application report the error. so my question is which ip be used in the mc/sg env and how i can use the dedicate ip 192.1.1.7 to communicate with others?

Hi,
First thing is what OS are you using.
I guess its 11.00 or above because that is a big difference from 10.20 as i have experienced and discussed with HP.

In OS 11.00 and above when the IP address is assigned to the package you'll see a noticable difference that its an alias network interface which is created.
i.e if the networks card is say lan0 and you have a package running on that node, it will have interface as lan0:1 which is physically the same interface. Thats is reason why for all communication purpose only hosts IP address will be seen.
Like if you assign security in /var/adm/inetd.conf on other servers outside cluster, you'll see putting package IP doesn't help, you'll have to use host IP, i.e host1's IP address.
For all these reasons when you ping the host outside firewall (or even if you do within the same side of firewall) the source IP assigned to the ping packet is always host1's IP not package IP address.

It sounds like what you want is for the application to 'bind' to the relocatable IP.

Suggest you read this customer_viewable document in the technical knowledge database:
KBAN00000700
ServiceGuard TCP/UDP Application Binding and Routing

If you need further assistance, discuss this issue with a network specialist in the HP Response Center
