Synchronizing Role Instance Configuration

Updated at: Aug 17, 2021 GMT+08:00


When Configuration Status of a role instance is Configuration expired or Configuration failed, you can synchronize the configuration data of the role instance with the background configuration.

After synchronizing a role instance configuration, you need to restart the role instance whose configuration has expired. The role instance is unavailable during restart.


You have synchronized IAM users (on the Dashboard tab page, click Click to synchronize on the right side of IAM User Sync to synchronize IAM users).
