Application Operations and Maintenance (O&M)-Scalable Open Financial Architecture(SOFAStack)-阿里云帮助中心

Application O&M provides application-centric operations for managing both applications and servers. You can perform five main operations: Restart, Online, Offline, Static resource deployment, and Initialize server.

Prerequisites

The server must be attached to the application and have a valid status.
For technology stacks provided by SOFAStack, such as SOFA Lite Web, SOFA Lite Core, and Spring, only the Linux operating system is supported. You must use the CentOS 7.x image provided by SOFAStack.

Create and execute an Application O&M ticket

On the App operations page, click Create. Configure the O&M ticket as described in the following table, and then click Create.

Configuration Item	Description
Title	Enter a title for the O&M operation. It can contain 1 to 50 Chinese or English characters.
Type	The following O&M operations are supported: Restart: Restarts an application that has been published on a server. This operation restarts the application, not the server. Online: Brings an application with the Offline status online. Offline: Takes an online application offline. It can also be used for servers with the Published or Publishing Failed status. Static resource deployment: Deploys static files to a specified directory on successfully published servers. Currently, only tar.gz compressed files are supported. Initialize server: Reinitializes servers under an application. You can initialize the data disk and the system disk.
