Chapter 2. Configuring Data Grid Servers

Apply custom Data Grid Server configuration to your deployments.

2.1. Customizing Data Grid Server configuration
Copia collegamento

Apply custom deploy.infinispan values to Data Grid clusters that configure the Cache Manager and underlying server mechanisms like security realms or Hot Rod and REST endpoints.

Important

You must always provide a complete Data Grid Server configuration when you modify deploy.infinispan values.

Note

Do not modify or remove the default "metrics" configuration if you want to use monitoring capabilities for your Data Grid cluster.

Procedure

Modify Data Grid Server configuration as required:

  • Specify configuration values for the Cache Manager with deploy.infinispan.cacheContainer fields.

    For example, you can create caches at startup with any Data Grid configuration or add cache templates and use them to create caches on demand.

  • Configure security authorization to control user roles and permissions with the deploy.infinispan.cacheContainer.security.authorization field.
  • Select one of the default JGroups stacks or configure cluster transport with the deploy.infinispan.cacheContainer.transport fields.
  • Configure Data Grid Server endpoints with the deploy.infinispan.server.endpoints fields.
  • Configure Data Grid Server network interfaces and ports with the deploy.infinispan.server.interfaces and deploy.infinispan.server.socketBindings fields.
  • Configure Data Grid Server security mechanisms with the deploy.infinispan.server.security fields.

2.2. Data Grid Server configuration values

Data Grid Server configuration values let you customize the Cache Manager and modify server instances that run in OpenShift pods.

Data Grid Server configuration
