Red Hat Summit1.2.5. Passing Data Grid Server configuration at startup
Specify custom configuration when you start Data Grid Server.
Data Grid Server can parse multiple configuration files that you overlay on startup with the --server-config argument. You can use as many configuration overlay files as required, in any order. Configuration overlay files:
-
Must be valid Data Grid configuration and contain the root
serverelement or field. - Do not need to be full configuration as long as your combination of overlay files results in a full configuration.
Data Grid Server does not detect conflicting configuration between overlay files. Each overlay file overwrites any conflicting configuration in the preceding configuration.
If you pass cache configuration to Data Grid Server on startup it does not dynamically create those cache across the cluster. You must manually propagate caches to each node.
Additionally, cache configuration that you pass to Data Grid Server on startup must include the infinispan and cache-container elements.
Prerequisites
- Download and install the server distribution.
-
Add custom server configuration to the
server/confdirectory of your Data Grid Server installation.
Procedure
-
Open a terminal in
$RHDG_HOME. Specify one or more configuration files with the
--server-config=or-cargument, for example:bin/server.sh -c infinispan.xml -c datasources.yaml -c security-realms.json
