Background information

You can use the Batch Instance Operations feature of Operation Orchestration Service (OOS) to perform a same operation on multiple Elastic Compute Service (ECS) instances. OOS supports the following batch operations on multiple instances: sending a remote command, performing basic O&M operations, and modifying instance attributes. Examples of supported remote commands are shell commands in Linux and Bat and PowerShell commands in Windows. Basic O&M operations supported include starting, stopping, restarting, initializing, and replacing the system disk of an instance. Instance attributes that can be modified in batches include the instance name, host name, and instance description.

  2. In the left-side navigation pane, choose Common O&M Tasks > Batch Instance Operations.
  3. On the Batch Instance Operations page, click Create. In the Select Task Type section, set Task Type.

    You can select Send Remote Commands or Instance Operations. In this example, select Send Remote Commands. Select Linux Shell (such as echo hello and hostname) for Command Type and enter df -h in the command content.
