WebSphere Application Server & Liberty

Hello, we're migrating an old IBM Operational Decision Manager version running on WAS to the latest ODM 8.11 release running on Liberty. We need both releases running on different ports of the same node while configuration finish. Direct access to the nodes is not allowed in this customer, access is configured in IHS.

I don't know much about IHS,  I found a pluginUtility that allows mergin 2 plugins. But I have some questions:

¿Is it possible to merge 2 plugins generated by different application servers like WAS and liberty?

¿How can I configure IHS to provide access to same routes in 2 application servers in the same host?

To be more clear, I need is something like this:

http://<IHS-host>:<port1>/DecisionService/...  ==> http://<node>:<was-port>/DecisionService /...

http://<IHS-host>:<port2>/DecisionService/...  ==> http://<node>:<liberty-port>/DecisionService /...

Thanks in advance. 

Hi Eduardo, merging traditional and liberty should work. To get the behavior you want, I suggest:

1. make a copy of both the WAS and Liberty plugin-cfg.xml
2. Update the default_host virtualhost of each XML so they are non-overlapping and match the webserver port1/port2
3. merge the files using the Liberty pluginUtility

You should end up with two virtual hosts, two ServerClusters, and two Route tags. 

Route tags are best read right-to-left and map a virtualhost + URIGroup to a ServerCluster.

Thanks in advance. 

I should have added, that whichever version gets the non-standard port, it will need to be reflected in the appserver virtual host configuration.

Hi Eric, thank you very much. I think that I understood, but I'm very new to IHS, just to be sure.

I should edit both plugins and replace the default virtual host name ("*") by two different <virtual-host-name> for was and liberty backends. I can keep the default ports (80 and 443) in both plugins and it is safe.

So, I edit each plugin and instead of:

  <VirtualHostGroup Name="default_host">      <VirtualHost Name="*:80"/>      <VirtualHost Name="*:443"/>  </VirtualHostGroup>

I replace by:

<VirtualHostGroup Name="default_host">      <VirtualHost Name="<virtural-host-name>:80"/>      <VirtualHost Name="<virtual-host-name>:443"/></VirtualHostGroup>

Is it like this?
