Setting up a new proxy core group
It is necessary to separate the WebSphere® Application Server (WAS) proxy server and the PushNotificationClusters into different core groups to ensure that requests for the PushNotificationClusters do not get routed to the HTTP Server (IHS) simultaneously.
About this task
Procedure
-
Create a new proxy core group for the proxy server and the PushNotificationClusters.
- On your Deployment Manager (DM) console, navigate to .
- Ensure that the PushNotificationClusters and the WAS proxy server are stopped before proceeding.
- Ensure that the WAS proxy server nodeagent is stopped before proceeding.
- Click New.... Specify a new core group name.
- Accept the default values for the rest of the settings. Click Apply and save the configuration if prompted.
-
Assign PushNotificationClusters and proxy server components to the proxy core group.
- Click DefaultCoreGroup and then select Core group servers.
- Select all elements relating to the PushNotificationClusters and the WAS proxy server. Include any nodeagents associated with the proxy server.
- Click Move....
- The To core group option should already be selected to be the ProxyCoreGroup that you set up earlier. If not, or if you have multiple core groups, make sure that the Proxy Core Group option that you previously set up is selected.
- Click Apply and save the configuration file if prompted.
-
Set up the Core Bridge interfaces.
- The core group bridge service enables the exchange of high availability information among core groups within the same cell, as well as among core groups in different cells. You must set up core bridge interfaces within the DefaultCoreGroup and the ProxyCoreGroup in order for them to communicate with each other at a high level. On your DM console, navigate to .
- Expand DefaultAccessPointGroup. You should see your DefaultCoreGroup and your ProxyCoreGroup listed.
- Select DefaultAccessPointGroup, and then select Core group access points.
-
Select DefaultCoreGroup, which might be displayed as
CGAP_1\DefaultCoreGroup
and click Show Detail. - Select Bridge interfaces.
- Click New.... A list of the various elements of the associated servers and WebSphere® server within the CoreGroup is displayed.
- For DefaultCoreGroup, select each of the Cluster and Servers from the associated WAS application nodes. You can only select one option at a time, so select one option, click Apply, save the configuration file, and repeat this process by clicking New. Repeat this procedure until all Cluster#_server# types are selected.
- Follow the link breadcrumb trail on your DM and navigate to Show Detail. . Select your proxy core group from the list and click
- Select Bridge interfaces.
- Click New.... Select one option from the list, click Apply, save the configuration file, and repeat as needed.
-
Verify the bridge interfaces.
- On your DM console, navigate to .
- Expand all + options for the listed Core Groups and their access points. You should now see your bridge interfaces set up accordingly.
- Stop, synchronize, and restart your node agents. If you restart your deployment after assigning the bridge interfaces, and the initial loading of the bridge interfaces causes an error, restart the Java™ Virtual Machines (JVMs).
