Command Line Shell Reference

Overview

The AppLogic command-line shell gives you control of all aspects of an AppLogic grid. The shell is located in the AppLogic controller and can be accessed over SSH using any suitable SSH client package. The shell commands are designed in order to 1). make the shell easy to use by humans, 2) provide simple means for scripting automation, and 3) support advanced web interfaces and datacenter management systems.

This section specifies the command line usage of the AppLogic Shell. Each shell command is executed using one of the following three command line forms:

command [ args ]*

object command [ args ]*

command object [ args ]*

Where

• object - specifies the type of object and may be: grid, server, application, component, interface, volume, catalog, class, appclass, user, or log.
• command - specifies the command that is to be executed
• args - specifies additional command-specific arguments.

The "object command" and "command object" forms are interchangeable, e.g. app start and start app are both valid and will produce the same result. This is done to avoid religious wars over which comes first and promote your freedom of choice.
