> # Syntax of Operator Interface Commands

> The syntax for Operator Interface commands is:

>     compid command parms

> where:

> `compid` | is the ID of the server component to which the command is directed. Valid component IDs are: CNTL - (Server Controller Tasks) LOGR - (Messaging Component) DB2 - (DB2 Component) RRS - (RRS Component) THPL - (Threadpool Component) XA - (XA Component)
> `command` | is the command name.
> `parms` | are the parameters of the command.

> For example:

> `CNTL HALT` shuts down the Server immediately.

> NOTE: When using the Operator Interface, you can repeat the last command you entered by pressing F24 or Shift+F12.
