Introduction: System administration
We can administer the WAS through scripts, command line tools, the admin console, or the Java programming interface. You administer server processes, topological units referenced as nodes and cells, and the configuration repository where configuration information is stored in XML files.
A variety of tools, processes, and configuration files are provided for administering WAS v7:
- Administrative topology
Servers, nodes and node agents, cells and the dmgr are fundamental concepts in the admin universe of WAS ND. It is also important to understand the various processes in the admin topology and the operating environment in which they apply.
Graphical interface that provides many features to guide you through deployment and systems administration tasks. Use it to explore available management options.
- wsadmin scripting
Non-graphical command interpreter environment enabling you to run admin operations in a scripting language. We can also submit scripting language programs to run in batch mode. The wsadmin tool is intended for production environments and unattended operations.
- Command line tools
Programs run from an operating system command-line prompt to perform specific tasks, as opposed to general purpose administration. Using the tools, we can start and stop appservers, check server status, add or remove nodes, and complete similar tasks.
WAS ND supports a Java programming interface for developing admin programs. All of the admin tools supplied with WAS are written according to the API, which is based on the industry standard JMX specification.
Product configuration data resides in XML files that are manipulated by the previously-mentioned admin tools.
