  • Cluster Information: Table 1 lists the related parameters.
  • Database Attribute: Table 2 lists the related parameters.
  • Node Configuration: Table 3 lists the related parameters.
  • Network: Table 4 lists the related parameters.
Table 1 Cluster information

Parameter

Description

Cluster Name

Cluster name specified when the cluster is created

Cluster Status

Cluster running status. For details, see Table 2.

Parameter Group

Parameter group associated with the cluster and its configuration status. You can click the parameter group name to view and edit it on the parameter group page.

Task Information

Cluster task status. For details, see Table 3.

Cluster ID

ID of the cluster

Nodes

Number of nodes in the cluster

Cluster Version

Cluster version information

Used Storage Capacity

Used storage capacity of the cluster

Created

Time when the cluster was created

Last Snapshot Created

Time when the last snapshot was created

Maintenance window of the cluster

You can click Configure on the right of Maintenance Window to configure the maintenance window. For more information, see section Configuring the Maintenance Window.

Table 2 Database attribute parameters

Parameter

Description

Default Database

Database that is automatically created during cluster creation. When you connect to the cluster for the first time, you need to connect to the default database.

Initial Administrator

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

Port

Port for accessing the cluster database over the public network or private network. Database port specified during cluster creation. It is used to listen to client connections.

JDBC URL (Private Network)

In the private network environment, you can use the JDBC URL (private network) to connect to the cluster when developing applications.

JDBC URL (Public Network)

In the public network environment, you can use the JDBC URL (public network) to connect to the cluster when developing applications.

Private Network Domain Name

Name of the domain for accessing the database in the cluster through the private network. The private network domain address is automatically generated when you create a cluster. The default naming rule is as follows: cluster name.dws.otc-tsi.de

NOTE:

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

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

For more information, see section Managing Access Domain Names.

Private Network IP Address

IP address for accessing the database in the cluster through the private network. The private network address is automatically generated when you create a cluster.

Public Network Domain Name

Name of the domain for accessing the database in the cluster through the public network.

NOTE:
  • If you have not bound an EIP to the cluster, Public Network IP Address, Public Network Port, and Public Network Domain Name are left blank.
  • If you bind an EIP during cluster creation, the public network domain name is automatically generated. The default naming rule is as follows: cluster name.dws.t-systems.com
  • Bind an EIP to the cluster before binding the public network domain name to the cluster. Click Create to bind the public network domain name to the cluster.
  • You can click Modify to modify the public network domain name bound to the cluster. The domain name contains 4 to 63 characters, which consist of letters, digits, and hyphens (-), and must start with a letter.
  • You can click Release to release the public network domain name bound to the cluster.

For more information, see section Managing Access Domain Names.

Public Network IP Address

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

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

ODBC URL

In DWS, you can use an ODBC driver to connect to the database. The drivers can connect to the database through the ECS in the public cloud or over the Internet.
