Administer

Administration is the set of tasks by which you prepare and then monitor the environment into which applications are deployed.

Administrative activities include:

• Configuring appservers and the resources in the environment in which those servers run

• Installing, updating, and uninstalling applications (see also Deploying, as deploying is distinguished from administering in this documentation and J2EE specification)

• Starting, stopping, and monitoring processes used in the product Requesting dynamic behavior changes for live runtime components

• Administering clusters of servers (Network Deployment)

• Accessing and managing components on remote nodes (Network Deployment)

Preparing the environment includes tasks such as establishing globally used security IDs and database connections.

Managing appservers involves all aspects of the components that are combined into the runtime for the server process. Such components include the JVM and the ORB. There is a distinct difference between administering the configuration data for servers and administering the live objects that are executing within a running server. Server administration includes both of these activities. The server aspects of Web services and messaging support also must be managed.

Applications are assembled from multiple component parts and then deployed. Administration of deployed applications includes:

• Configuring application components

• Deploying applications (discussed separately in documentation)

• Controlling the execution state of an installed application

Applications can be updated and redeployed with revised code or deployment descriptors. Use administrative tools to control several application services, such as transaction services and session services.

Administering the resources that exist in the server environment includes configuring:

• Embedded JMS provider (if it is used)

• JDBC resources

• Java Connector Architecture connections and factories

• JavaMail and URL resources

• Resource environment reference factories

For more information about resources, see Welcome to Resources.

You have many options for configuring and controlling system security settings. While the configurations of many components are fairly discrete, security configurations are likely to be referenced in the configurations of various other components such as the Web container, administrative service, and Java Connector Architecture configurations. For additional information, see Welcome to Security.
