Cluster with horizontal cluster members
- Complete the installation of a WCS node.
- Create a WCS instance.
- Backup the WAS administrative configuration.
- Federate the WCS node into a deployment manager cell.
- Prepare additional nodes for each node that to add to the cluster.
- Define the JDBC provider path for each node that contains a server that is or will be a member of the WCS cluster..
- Create a WCS Cluster.
- Add additional cluster members if required.
- Start the WAS administration server.
- Launch the WebSphere administrative console.
- Create an Internal Replication Domain for the application:
It is possible to create this as part of the initial cluster setup. If you have already created a Replication Domain for the application, you can use the existing one.
- Click...
Environment | Replication domains | New
- For Number of replicas, select Entire Domain.
- Save the changes.
- Enable cache replication in each clone.
- Click Servers > Application servers > Clone Name > Container Services > Dynamic Cache Service.
- To enable replication, select Enable Cache Replication.
- Choose a replication domain.
- Choose a replication type. For WCS, the recommendation is to use Not shared. Refer to Dynamic cache service settings for other options.
- Repeat steps a-d for each clone.
- Save the changes.
- Instead of using a default setting, always explicitly specify the replication mode for each entry in cachespec.xml.
For example:
- Add <sharing-policy>shared-push</sharing-policy> to each cache-entry in cachespec.xml.
You can choose not to replicate certain cache entries.
To configure a cache entry to not replicate, set...
<sharing-policy>not-shared</sharing-policy>
- Regenerate the Web server plug-in and copy the plug-in to the Web server.
Verify the Web server configuration file, httpd.conf, points to right Web server plug-in file.
- Start the WCS cluster.
