RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
DBClusterId	string	Yes	The cluster ID.	pc-**********
DBNodeIds	string	No	The IDs of the nodes. By setting this parameter, you can modify the parameters of the cluster and specified nodes. Separate multiple node IDs with commas (,). Note If this parameter is not specified, only the cluster parameters are modified.	pi-********,pi-********
Parameters	string	No	The JSON string that consists of parameters and their values.	{"wait_timeout":"86","innodb_old_blocks_time":"10"}
ParameterGroupId	string	No	The ID of the parameter template.	pcpg-**********
PlannedStartTime	string	No	The earliest time to start the scheduled task. Specify the time in the `YYYY-MM-DDThh:mm:ssZ` format. The time must be in UTC. Note The start time can be any time within the next 24 hours. For example, if the current time is `2021-01-14T09:00:00Z`, you can specify a time that ranges from `2021-01-14T09:00:00Z` to `2021-01-15T09:00:00Z`. If you leave this parameter empty, the task is immediately executed.	2021-01-14T09:00:00Z
PlannedEndTime	string	No	The latest time to start the scheduled task. Specify the time in the `YYYY-MM-DDThh:mm:ssZ` format. The time must be in UTC. Note The latest start time must be 30 minutes or more later than the earliest start time. If you specify `PlannedStartTime` but not this parameter, the latest start time of the task is `the earliest start time + 30 minutes` by default. For example, if you set `PlannedStartTime` to `2021-01-14T09:00:00Z` and leave this parameter empty, the task will start no later than `2021-01-14T09:30:00Z`.	2021-01-14T09:30:00Z
FromTimeService	boolean	No	Specifies whether to immediately or scheduledly modify parameters and restart the cluster. Valid values: false (default): scheduled execution true: immediate execution	false
ClearBinlog	boolean	No	Specifies whether to clear binlog. This parameter is valid only when binlog is disabled.
StandbyClusterIdListNeedToSync	string	No	The list of GDN standby clusters to which you want to synchronize the parameter settings.	gdn-********,gdn-********
