You execute commands by specifying them in a UAP. The specified commands are executed at the HiRDB server.

The following SQL statements are used to execute commands from a UAP:

• CALL COMMAND statement
  This statement is used to execute HiRDB operation commands and utilities. The CALL COMMAND statement does not require any preparations for command execution.
  
• COMMAND EXECUTE
  This statement is used to execute HiRDB operation commands, utilities, and OS commands.
  Because execution of commands from COMMAND EXECUTE is implemented by collaboration between the HiRDB client and HiRDB Control Manager - Agent, HiRDB Control Manager - Agent must be installed on the HiRDB server. For details about HiRDB Control Manager - Agent, see the respective Release Notes.
  Command execution from COMMAND EXECUTE can be used only when the UAP is written in C.
  The following figure provides an overview of command execution from COMMAND EXECUTE.
