Current working zone of the cluster.

AZ

AZ selected during cluster creation

VPC

VPC selected during cluster creation.

A VPC is a secure, isolated, and logical network environment.

After a DWS cluster is created, its VPC cannot be changed. However, you can edit and modify the current VPC. You can click the VPC name to go to the VPC details page to configure it. For details about VPC operations, see Modifying a VPC in the Virtual Private Cloud User Guide.

Subnet

Subnet selected during cluster creation.

A subnet provides dedicated network resources that are isolated from other networks, improving network security.

After a DWS cluster is created, its subnet cannot be changed. However, you can edit and modify the current subnet. You can click the subnet name to go to the subnet details page to configure it. For details about subnet operations, see Modifying a Subnet in the Virtual Private Cloud User Guide.

Security Group

Security group selected during cluster creation.

After a DWS cluster is created, you can change the security group. You can also add, delete, or modify security group rules in the current security group.

  • To change the security group, click Modify on the right of the security group name, select the security group you want to use, and click OK. Changing the security group of a cluster may cause brief service disruption. Exercise caution when performing this operation. To improve network performance, limit your selection to no more than five security groups.
  • To modify an existing security group rule, click the security group name to go to the security group details page. For details about security group operations, see Security Group in the Virtual Private Cloud User Guide.
Table 3 Billing information

Parameter

Description

Billing Mode
  • Pay-per-use: You can enable or disable an instance anytime you want. You are billed by your use duration on an hourly basis (the time is accurate to minutes) and the system generates a bill every natural hour and deducts fees from your account balance.
  • Yearly/Monthly: This mode provides a larger discount than the pay-per-use mode and is recommended for long-term users.

Created

Time when a pay-per-use or yearly/monthly cluster is created

Order (available for the yearly/monthly billing mode)

Order number of a yearly/monthly cluster

Expiration Date (for yearly/monthly billing)

Expiration time of a yearly/monthly cluster

Upon Expiration

Automatic deletion upon expiration is supported. For details about the grace period, see Grace Period and Retention Period.
Table 4 Connection

Parameter

Description

Private Network Domain Name

Domain name for accessing the cluster database through the internal network. The domain name corresponds to all CN IP addresses. The private network domain address is automatically generated when a cluster is created. The default naming rule is cluster name.dws.myhuaweicloud.com.

  • If the cluster name does not comply with the domain name standards, the prefix of the default access domain name will be adjusted accordingly.
  • Load balancing is not supported.

You can click Modify to change the private network domain name. The access domain name contains 4 to 63 characters, which consists of letters, digits, and hyphens (-), and must start with a letter.

For details, see Managing DWS Cluster Access Domain Names.

Private Network IP Address

IP address for accessing the database in the cluster over the private network.

  • A private IP address is automatically generated when you create a cluster. The IP address is fixed.
  • The number of private IP addresses equals the number of CNs. You can log in to any node to connect to the cluster.
  • If you access a fixed IP address over the internal network, all the resource pools will run on a single CN.
  • If IPv6 is enabled for a cluster, both IPv4 and IPv6 private addresses will be displayed. You can use either of them as needed.

Public Network Domain Name

Name of the domain for accessing the database in the cluster over the public network. For more information, see Managing DWS Cluster Access Domain Names. Load balancing is not supported.

Public Network IP Address

IP address for accessing the database in the cluster over the public network.

  • If no EIP is assigned during cluster creation and Public Network IP Address is empty, click Edit to bind an EIP to the cluster.
  • If an EIP is bound during cluster creation, click Edit to unbind the EIP.

Initial Administrator

Database administrator specified during cluster creation. When you connect to the cluster for the first time, you need to use the initial database administrator and password to connect to the default database.

Port

Port number for accessing the cluster database through the public network or private network. The port number is specified when the cluster is created.

Default Database

Database name specified when the cluster is created. When you connect to the cluster for the first time, connect to the default database.

ELB Address

To achieve high availability and avoid single-CN failures, a new cluster needs to be bound to ELB. You are advised to use the ELB address to connect to the cluster.
Table 5 Storage/Backup capacity

Table 6 O&M account

Parameter

Description

O&M Account

Check the created O&M account. Its name format is om_user_First eight numbers in the cluster ID. The gs_role_analyze_any, gs_role_vacuum_any, gs_role_read_all_stats, and gs_role_signal_backend roles will be assigned to the account. For details, see Preset Roles.

Account Status

Displays the status of the current cluster O&M account, which can be Normal or Expired.

Expires

Indicates the expiration time of the O&M account of the current cluster.

You can click Modify to change the KMS master key name. You can select a key name or enter a key ID. For details, see 4.

Last Key Rotation Time

Indicates the time when the last encryption key is rotated when Encrypt DataStore is enabled.

Changing a Cluster Name

You can change the name of a created DWS cluster.

After the cluster name is changed, the names of all nodes in the current cluster are changed accordingly. If the cluster name fails to be changed, the cluster functions are not affected. You can contact technical support to rectify the fault if needed.

Notes and Constraints

  • If the cluster is in the Unavailable status or is performing other tasks, the cluster name cannot be changed. You can change the cluster name only after the cluster status changes to Available or the running tasks are complete.
