ApsaraDB RDS:Manage scheduled events

Prerequisites

A pending O&M event exists.

Usage notes

• Events fall into the following levels based on urgency:

  • [S0: Urgent] Risk fixing: Events at this level are unexpected events that need to be fixed at the earliest opportunity to prevent faults in most cases, such as urgent replacement, upgrades, or updates of faulty versions, host exception fixes, and SSL certificate upgrades before expiration. Event notifications may be sent three days or more in advance and the window for changing the scheduled switchover time is short.

  • [S1: Scheduled] System maintenance: Events at this level are resolution of low-risk issues or scheduled upgrades of software and hardware in most cases. Event notifications are sent more than three days in advance and you can cancel the events.

• To ensure that you can receive notifications of scheduled O&M events, select the notification methods and configure the contacts for ApsaraDB Fault or Maintenance Notifications in the Message Center console. We recommend that you specify database O&M personnel as the contacts. The notification methods include Email and Internal Messages. We recommend that you select Email to improve the success rate of notifications.

• If you want to be informed of O&M events at the earliest opportunity or want to customize event-driven O&M automation, you can use CloudMonitor to configure system event subscriptions. Then, cloud database services push CloudMonitor system events related to the lifecycle of O&M events, such as subscription, start, end, and cancellation. For more information, see Manage event subscription policies (recommended). For information about CloudMonitor system events to which you can subscribe, see the "Appendix 1 CloudMonitor-related system events" section of this topic.

  Sample CloudMonitor event:

  {
    "eventId": "c864b30b-7f69-5f04-b0e7-8dfb0eabcfd9", // The event ID. The same event has the same ID.
    "product": "RDS",                                  // The service code.
    "reason": "Host software/hardware upgrade",        // The cause of the event.
    "extra": { 
      "impactEn": "Transient instance disconnection",  // The impact of the event.
      "eventCode": "rds_apsaradb_transfer",            // The code of the type of the O&M event.
      "eventNameEn": "Instance migration",             // The name of the O&M event.    
      "switchTime": "2024-09-15T01:30:00+08:00",       // The scheduled switchover time, which is the time when a transient connection occurs on the instance if a switchover is performed.
      "startTime": "2024-09-14T21:30:00+08:00",          // The scheduled start time of the event, which is the time when the event enters the scheduling queue and waits to be executed.
      "cancelCode": "OutOfGoodPerfBySoftHardwareUpgrade", // The cancellation risk code. For more information, see the "Appendix 2 Detailed cause codes and cancellation risks" section of this topic.
      "detailCode": "HostSoftHardwareUpgrade",            // The detailed cause code. For more information, see the "Appendix 2 Detailed cause codes and cancellation risks" section of this topic.
      "instanceInfo": ""
    },
    "instanceId": "rm-2ze9d66o65q1g02g6",             // The instance ID.
    "eventType": "Maintenance",
    "instanceComment": "rm-2ze9d66o65q1g02g6",        // The alias of the instance.
    "instanceType": "Instance",
    "publishTime": "2024-09-10T16:01:47+08:00"
  }

Procedure

1. Log on to the ApsaraDB RDS console.

2. In the left-side navigation pane, click Event Center. In the top navigation bar, select the region in which the RDS instance resides.

   Note

   If a pending O&M event requires you to schedule a time for the O&M operation, a message appears to prompt you to schedule the time at your earliest opportunity.

3. Optional. On the Scheduled Events tab, configure the recurring time window.

   Note

   The Recurring Time Window Settings panel provides the global configuration items of proactive O&M events except events that are used to fix high-risk vulnerabilities. After you configure the periodic switching time, the scheduled time of switchovers for newly generated proactive O&M events is automatically changed based on the configured time interval. If you do not configure the periodic switching time, the scheduled time of switchovers for newly generated proactive O&M events is automatically changed based on the maintenance window of your RDS instance. For more information, see Configure a maintenance window.

   1. Click Recurring Time Window Settings.

   2. In the panel that appears, configure the parameters and click Save.

4. On the Scheduled Events tab, view the details of the event. To change the switching time of the event, select the RDS instance that you want to manage and click Schedule Event.

   Note

   The displayed information varies based on the event type.

5. In the Schedule Event dialog box, configure the scheduled switching time and click OK.

   Note

   • If you select Earliest Execution Time, the system automatically provides the earliest switching date and time for the next O&M operation. After you save the settings, the RDS instance prepares to switch over and enters the Pending state. If you do not select this option, you can customize the date and time.

   • The time that is specified by the Scheduled Switching Time parameter cannot be later than the time that is specified by the Deadline parameter.
