Multiple WebSphere App Servers bound to different IPs

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

Hi,

Is it possible to have multiple WebSphere application servers running on the same machine listening to the same port number bound to different IP addresses? If so how do we set it up?

Any help is greatly appreciated
Thanks!

To be more specific, I wanted to know if it is really possible for there to be two running instances of websphere app server both listening to port xyz on a single OS that could be configured to bind to different IP addresses.

Thanks!

multiple app servers running on the same machine should have different port numbers. If you assign same port to all the servers port conflict will occur. You could assign the same ports to all your servers but only one server instance should be running at a time.

what matters is socket ..so if you configure different IP addresses to listen on same port ..that should also be sufficient .I am assuming , you are also taking care of firewall rules and accessibility.

how do you bind the port to a specific IP ?

i think most likely there may be port conflict as the JVMs are on the same OS even if you can bind it to be different IP..

it may be possible if you have different zones (for solaris) or different LPARs (AIX)

i guess u could do it by creating seperate virtual hosts

Hi All,

Did any one get a proper solution to this issue.

I got some online material for this but it is not working.Please suggest a solution. Thanks

From my experience, each application server requires unique ports.  If you define multiple application servers to the same ports in the WebSphere Admin Console, you will run into a conflict upon starting the second JVM that prevents it from starting.

Is the question geared more towards inbound web connections coming over port 80/ 443/ etc?  If so, you still require a unique port for the WC_defaulthost and WC_defaulthost_secure for each JVM when running multiple JVMs on a single OS install. But, the plugin file you generate for your web servers (based on the application mappings in the console) takes care of the redirection to the corresponding JVM based on the appropriate web server handling the inbound connection.

Thanks for the info. I installed WAS using unique port numbers instead of using the same ones.
