Managing Command Operation Tasks
A bastion host supports fast operations. You can manage many resources concurrently by executing commands. You can execute the same command on multiple host resources that use the SSH protocol through one task, and the corresponding execution results are returned accordingly.
This topic describes how to manage command tasks, including creating, executing, and stopping command tasks, and viewing task execution results.
Constraints
- Fast operation is supported by professional editions only.
- Fast operation tasks apply only to Linux hosts using the SSH protocol.
- Currently, Fast operation tasks cannot be performed on Windows host, database, or application resources.
Prerequisites
- You have the management permissions for the Fast Operation module.
- You have obtained the access permissions for the resources.
- The network connections between the managed hosts and the bastion host are normal.
Procedure
