Update the configurations of a store

OceanBase Migration Service (OMS) Community Edition allows you to view and update the configurations of a specified store. When you update the configurations, the current configurations of the store are displayed by default. You can view or modify the configurations of the store.

Background information

The newly added or updated Store component will be updated to the topic by default, and subsequent Store component startups will use the updated parameters.

For example, if there are N Store components (N >= 1) in the data migration task before the update, and the user selects one Store component for updating, the execution logic for the update is as follows, while the configurations of the other N-1 Store components remains unchanged.

1. Update the configurations of the selected Store component.

2. Update the configurations of the Subtopic corresponding to the Store component.

Limitations

• OMS Community Edition allows you to update the configurations of a store in the Running , Stopped , Abnormal , or Unexpected Exit state.

  Notice

  Store configurations are usually updated in optimization or emergency scenarios. Exercise caution when you perform this operation.

• If the new configurations are incorrect, the store may run abnormally and the corresponding data migration or synchronization task may fail. You can contact OMS Community Edition Technical Support as needed.

• After you update the configurations of a store, the system will restart the store for the update to take effect. Proceed with caution.
