Batch Executing Commands on COC

Precautions

• You can perform this operation only when the selected instances are running.
• UniAgent of the selected instance must be running. For details about UniAgent-related operations, see Installing UniAgent on a Host.
• If the selected ECSs run different OSs (Linux and Windows), you need to deliver commands to the ECSs separately.

Constraints

Currently, only ECSs support batch command execution.

Batch Executing Commands on ECSs

1. Log in to COC.
2. In the navigation pane, choose Resource O&M > Batch Resource Operations.

   Table 1 Parameter configurations

   Parameter	Description
   Target Instance	Click Add and configure the parameters in the Select Instance dialog box. For details about the parameters, see Table 2 Parameters for selecting an instance.
   Operating System	OS of the target instance. Currently, Linux and Windows are supported. Select the operating system of the target instance.
   Executed By	User who executes the commands. For an ECS running on Windows, the preset value is system and the value cannot be changed. For an ECS running on Linux, the preset value is root. You can change it as needed.
   Execution Plan	Execution plan of the commands. The preset value is Execute Now.
   Timeout Interval	Timeout interval for an individual command execution. If the command execution times out, the command submission will be stopped forcibly. Value range: 6 to 1800 seconds (24 hours) Unit: second
   Command Type	Type of the script commands that can be submitted. For an ECS instance running Windows, you can set this parameter to Bat. For an ECS instance running Linux, Shell is used by default and Python is also supported.
   Command Input	Input box of the commands to be submitted. The input must be a command that produces a result after a single execution, meaning no further interaction with the command's output is required. NOTE: After a command is executed, you can enter another command in the command input box and run the command.
   Command Output	Output box of the commands. You can view the command execution results.
