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.

Read the impact section in the feature documentation carefully before configuring this parameter. We recommend that you perform the change during off-peak hours. Immediate (default): The change takes effect immediately. MaintainTime: The change takes effect during the maintenance window. ScheduleTime: The change takes effect at a specified time. The time must be at least 12 hours later than the current time, and the actual switchover time follows the rule: EffectiveTime = ScheduleTime + SwitchTime. Valid values: ScheduleTime : The time must be at least 12 hours later than the current time, and the actual switchover time follows the rule: EffectiveTime = ScheduleTime + SwitchTime	MaintainTime

To perform the upgrade, you must specify both DBInstanceClass and DBInstanceStorage, and the values must be the same as the current values. * For PostgreSQL instances, you can upgrade SSD cloud disks to any PL level of ESSD cloud disks, but you cannot downgrade ESSD cloud disks to SSD cloud disks.	local_ssd

Note The specified time must be later than the current time (the time when the call is initiated). Otherwise, the configuration change task will fail. After the task fails, you must wait for the order to be automatically voided before initiating the call again. If you only increase the storage capacity or change the ESSD storage type, the configuration change will be executed immediately after submission because it has no impact on the business. You do not need to configure this parameter.	2019-07-10T13:15:12Z
