     Policy	Description
     AliyunHologresFullAccess	Grants full access permissions on Hologres. If you attach this policy to the RAM user, the RAM user can view the information about all instances and purchase instances in the Hologres console. Note To view user information on the Users tab of an instance details page in the Hologres console, you must attach the AliyunRAMReadOnlyAccess policy to the RAM user.
     AliyunBSSOrderAccess	Grants permissions to view, pay for, and cancel orders in the Billing Management console. If you attach this policy to the RAM user, the RAM user can upgrade or downgrade instance specifications and renew instances in the Hologres console.
     AliyunRAMReadOnlyAccess	Grants read-only permissions on RAM. If you attach this policy to the RAM user, the RAM user can view the information about the current users, groups, and permissions on the Users tab of an instance details page in the Hologres console.
     AliyunHologresReadOnlyAccess	Grants read-only permissions on Hologres. If you attach this policy to the RAM user, the RAM user can view the information about all instances but cannot manage the instances in the Hologres console. For example, the RAM user cannot modify the network configurations of instances.

     Note

     • If you use a RAM user to purchase an instance, the RAM user and the Alibaba Cloud account are superusers by default.

     On the Create Custom Policy page, you can set the configuration mode to Script. Then, edit the script of the policy.
