Changes take effect after you to restart the server or redeploy the module.

The value of this attribute is bound to the domain's in-memory, working configuration when you instantiate the MBean. If you change this value for an MBean that is already instantiated, you can activate this change (which updates the domain's working configuration files), but you must re-instantiate the MBean to update the domain's in-memory configuration. To do so for MBeans that provide system-wide services, such as ServerMBean, restart all servers in the domain. For MBeans that represent deployed modules, redeploy the module on all servers; if the module is a component in an application, BEA recommends that you redeploy the entire application to avoid complications due to intra-application dependencies.
