asadmin

The asadmin command-line utility is the primary tool for administering Oracle GlassFish Server and other Java EE compliant application servers. It allows administrators to perform a wide range of management tasks, including starting and stopping the server, deploying and undeploying applications, configuring resources, managing security, and monitoring server performance. The asadmin tool is typically accessed from a command prompt or terminal and interacts with the running GlassFish Server instance.

Users can invoke asadmin with various subcommands, each designed for a specific administrative function. For instance, the 'start-domain' command initiates a GlassFish domain, while 'stop-domain' halts it. Application deployment is handled by commands like 'deploy' and 'undeploy', which manage the lifecycle of web applications, enterprise applications, and other deployable artifacts. Resource configuration, such as setting up JDBC data sources or JMS connection factories, is done through commands like 'create-jdbc-resource' or 'create-jms-resource'.

Security management features include commands for creating and managing users, groups, roles, and authentication realms. The 'list-users' command, for example, displays registered users. Monitoring capabilities are provided through commands that can retrieve server status, thread dumps, and other runtime information. The asadmin utility supports scripting, allowing administrators to automate repetitive tasks by creating shell scripts that execute multiple asadmin commands. It is an essential component for efficiently managing and maintaining GlassFish Server environments.
