Configuring a HetuEngine Maintenance Instance

Scenario

A maintenance instance is a special compute instance that performs automatic tasks. Maintenance instances are used to automatically refresh, create, and delete materialized views.

Only one compute instance can be set as a maintenance instance, and the maintenance instance can also carry original computing services at the same time.

Prerequisites

• You have created a user for accessing the HetuEngine web UI. For details, see Creating a HetuEngine User.
• The compute instance to be configured must be in the stopped state.

Procedure

1. Log in to FusionInsight Manager as a user who can access the HetuEngine web UI.
2. Choose Cluster > Services > HetuEngine to go its service page.
3. In the Basic Information area on the Dashboard page, click the link next to HSConsole WebUI. The HSConsole page is displayed.
4. Locate the row that contains the target instance, and click Configure in the Operation column.
5. Check whether Maintenance Instance in Advanced Configuration is set to ON. If not, change the value to ON.
6. After the modification is complete, select Start Now and click OK.
