How Do I Handle Data Loss in a HetuEngine Data Source?
Question
Why is the data source lost when I log in to the client to check the data source connected to the HSConsole page?
Answer
The possible cause of data source loss is that the DBService active/standby switchover occurs or the database connection usage exceeds the threshold.
- You can log in to FusionInsight Manager.
- View the alarm information and clear the DBService alarm based on the alarm guide.
