This topic describes how to set the maintenance window of an ApsaraDB RDS for PostgreSQL instance. The backend system performs maintenance on the RDS instance during the maintenance window. This ensures the stability of the RDS instance. The default maintenance window spans from 02:00:00 to 06:00:00 UTC+8. We recommend that you set the maintenance window to an off-peak hour. This allows you to avoid interruptions to your workloads.
Precautions
- Before the maintenance starts, ApsaraDB for RDS sends emails to the contacts that are associated with your Alibaba Cloud account.
- To ensure stable maintenance, the RDS instance enters the Maintaining Instance state during the maintenance window. While the RDS instance stays in the Maintaining Instance state, database access and query operations such as performance monitoring are still available. However, apart from account and database management and IP address whitelist configuration, all the other modify operations such as upgrade, downgrade, and restart are temporarily unavailable.
- During the maintenance window, one or two brief disconnections may occur. Make sure that your application is configured to automatically reconnect to the RDS instance.
