Explanation:
A: Steps to Deploy Application using Administration Console
E: To enable the administration port for your domain:
Note: If you want to use the Administration Console to make configuration changes, you must first
click the Lock & Edit button in the Change Center. When you click Lock & Edit, you obtain a lock
on the editable hierarchy of Configuration MBeans for all servers in the domain (the edit tree).
As you make configuration changes using the Administration Console, you click Save (or in some
cases Finish) on the appropriate pages. This does not cause the changes to take effect
immediately; instead, when you click Save, you are saving the change to the edit tree and to the
DOMAIN_NAME/pending/config.xml file and related configuration files. The changes take effect
when you click Activate Changes in the Change Center. At that point, the configuration changes
are distributed to each of the servers in the domain. If the changes are acceptable to each of the
servers, then they take effect. (Note, however, that some changes require a server to be
restarted.) If any server cannot accept a change, then all of the changes are rolled back from all of
the servers in the domain. The changes are left in a pending state; you can then either edit the
pending changes to resolve the problem or revert the pending changes.
