7.6.  Demonstrate understanding of the WebSphere Application Server Network Deployment V8.0 XML files and their purpose.

[Note]

Config XML data

WebSphere Application Server's configuration data is stored in XML files. Knowing the structure and the content of these files is useful when it comes to understanding how the system operates.

In a Network Deployment environment, master copies of the xml files are stored in the cell repository on the deployment manager node. The master files overwrite local files on each node in a cell.

The config files are stored in the config directory for the specific profile defined for the WebSphere Application Server under the product installation directory. For example, the config files for a Deployment Manager profile are stored in /opt/IBM/WebSphere/AppServer/profiles/Dmgr01/config/. Within this directory is a specific WAS subdirectory hierarchy. At the top of the hierarchy is the cells directory, followed by the nodes, and then the servers directory.

For example, an Application Server with a Deployment Manager profile, Dmgr01, having a subdirectory hierarchy of cell, test317Cell01, node, test317CellManager01, and server, dmgr, can be shown as:

/opt/IBM/WebSphere/AppServer/profiles/Dmgr01/config/cells/test317Cell01/nodes/test317CellManager01/servers/dmgr/
