Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request syntax

PUT /pop/v1/sam/app/restartApplication HTTP/1.1

Request parameters

Parameter	Type	Required	Description	Example
AppId	string	Yes	The ID of the application.	0099b7be-5f5b-4512-a7fc-56049ef1****
MinReadyInstances	integer	No	The minimum number of available instances. Special values: If you set the value to 0, business interruptions occur when the application is updated. If you set the value to -1, the minimum number of available instances is automatically set to a system-recommended value. The value is the nearest integer to which the calculated result of the following formula is rounded up: Current number of instances × 25%. For example, if five instances are available, the minimum number of available instances is calculated by using the following formula: 5 × 25% = 1.25. In this case, the minimum number of available instances is 2. Note Make sure that at least one instance is available during application deployment and rollback to prevent business interruptions.	1
MinReadyInstanceRatio	integer	No	The percentage of the minimum number of available instances. Take note of the following rules: If you set the value to -1, the minimum number of available instances is not determined based on this parameter. Default value: -1. If you set the value to a number from 0 to 100, the minimum number of available instances is calculated by using the following formula: Current number of instances × (Value of MinReadyInstanceRatio × 100%). The value is the nearest integer rounded up from the calculated result. For example, if the percentage is set to 50% and five instances are available, the minimum number of available instances is 3. Note When MinReadyInstance and MinReadyInstanceRatio are specified and MinReadyInstanceRatio is set to a number from 0 to 100, the value of MinReadyInstanceRatio takes precedence.** For example, if MinReadyInstances is set to 5, and MinReadyInstanceRatio is set to 50, the minimum number of available instances is set to the nearest integer rounded up from the calculated result of the following formula: Current number of instances × 50%**.	-1
