Request parameters

ParameterTypeRequiredDescriptionExample
DBClusterIdstringYes

The cluster ID.

pc-****************
DBNodeIdsstringNo

The node ID. You can set this parameter to modify the parameters of a specified node or of the cluster. Separate multiple node IDs with commas (,).

Note If you do not specify this parameter, only the cluster parameters are modified.
pi-****************,pi-**********,
ParametersstringNo

The JSON string for the parameter and its value.

{"wait_timeout":"86","innodb_old_blocks_time":"10"}
ParameterGroupIdstringNo

The ID of the parameter template that is used for the instance.

pcpg-**************
PlannedStartTimestringNo

The earliest time to upgrade the specifications within the scheduled time period. Specify the time in the YYYY-MM-DDThh:mm:ssZ format. The time must be in UTC.

Note
  • The earliest start time of the task can be a point in time within the next 24 hours. For example, if the current time is 2021-01-14T09:00:00Z, you can specify a point in the time range from 2021-01-14T09:00:00Z to 2021-01-15T09:00:00Z.

  • If this parameter is empty, the upgrade task is immediately performed.

2021-01-14T09:00:00Z
PlannedEndTimestringNo

The latest start time to run the task. Specify the time in the YYYY-MM-DDThh:mm:ssZ format. The time must be in UTC.

Note
  • The value of this parameter must be at least 30 minutes later than the value of the PlannedStartTime parameter.

  • By default, if you specify the PlannedStartTime parameter but do not specify the PlannedEndTime parameter, the latest start time of the task is set to a value that is calculated by using the following formula: Value of the PlannedEndTime parameter + 30 minutes. For example, if you set the PlannedStartTime parameter to 2021-01-14T09:00:00Z and you do not specify the PlannedEndTime parameter, the latest start time of the task is set to 2021-01-14T09:30:00Z.

2021-01-14T09:30:00Z
FromTimeServicebooleanNo

Specifies an immediate or scheduled task to modify parameters and restart the cluster. Default value: false. Valid values:

  • false: runs the kernel upgrade task in a scheduled manner.
  • true: immediately runs the kernel upgrade task.
false
