You can override the properties specified in the ra.xml file of a resource adapter. Use the asadmin create-resource-adapter-config command to create a configuration for a resource adapter. Use this command’s --property option to specify a name-value pair for a resource adapter property.
You can use the asadmin create-resource-adapter-config command either before or after resource adapter deployment. If it is executed after deploying the resource adapter, the existing resource adapter is restarted with the new properties. For details, see the Sun Java System Application Server Platform Edition 8.2 Reference Manual.
