Command Line Shell Overview

The command line shell gives you control of all aspects of a grid. The shell is located in the controller and can be accessed over SSH using any suitable SSH client package. The shell commands are designed to do the following:

• Make the shell easy to use
• Provide simple means for scripting automation
• Support advanced web interfaces and datacenter management systems

This section specifies the command line usage of the Grid 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, user, log, message, or ha.
• command - specifies the command that is to be executed
• args - specifies additional command-specific arguments.

The "object command" and "command object" forms are interchangeable, for example, 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.

Note: Adhere to the naming conventions for CA AppLogic entities.
