Using the "cluster" profile, JDBC resources created on the DAS are enabled for
all instances while JNDI resources need to be explicitly enabled for a given set
of instances (at creation time or after). This doesn't sound right.
Either all resources should be enabled on all instances by default, or the
choice should be given to the user for both JDBC and JNDI resources as to which
instances are targets for those resources.
New users are left wondering why their JNDI resources are not enabled on their
cluster instances while JDBC pools are working fine.
