Changes take effect after you redeploy the module or restart the server.
If this attribute configures a module that you deploy (such as an application or
a JDBC data source that is part of an application) or a system resource whose configuration
is saved in a descriptor file instead of in the domain's
config.xml file (such
as a JDBC data source that is scoped at the system level), the module or resource cannot
process the change until you redeploy it or restart its host server. 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.
If this attribute configures some other part of the domain (such as a server, a cluster, or an EJB container), the system cannot process the change until you restart the server or cluster.
