HoloWeb is a data processing and development tool for Hologres. This topic describes how to log on to a Hologres instance using HoloWeb. Three methods are available: using the dialog box that appears automatically when you first open HoloWeb, right-clicking an instance in the unlogged-on instances list, or connecting to an instance in another region through Metadata Management.
Prerequisites
Before you begin, ensure that you have:
-
An Alibaba Cloud account with identity verification completed
-
An active Hologres instance. For more information, see Purchase a Hologres instance
Log on to an instance
Step 1: Open HoloWeb
-
Log on to the Hologres Management Console.
-
In the navigation pane on the left of the top menu bar, select the region where your instance is deployed.
-
Click Go to HoloWeb.
Step 2: Connect to an instance
Choose one of the following methods based on your situation.
Method 1: Use the Connect to Instance dialog box
When you open HoloWeb without an active connection, the Connect to Instance dialog box appears automatically. Configure the parameters and click OK.
| Parameter | Description |
|---|---|
| Instance name | Select an unlogged-on instance from the drop-down list. The list shows all instances that your root account can access in the current region. The Hologres engine instance automatically generates a Virtual Private Cloud (VPC) network type instance; this instance appears in the list and cannot be edited or deleted. |
| Select database | Choose whether to log on to an existing database or create a new one. |
| Database name | If logging on to an existing database, select it from the drop-down list. If creating a new database, enter a name. |
| Access policy | Appears only when you select Create a new database. Choose the access control model for the new database: Simple Permission Model (SPM) for role-based access suited to most teams, Schema-level Permission Model (SLPM) for schema-level isolation, or the standard PostgreSQL authorization model for fine-grained privilege control. |
Method 2: Connect from the unlogged-on instances list
In the unlogged-on instances list, right-click the target instance and select Connect to Instance. Configure the parameters as described in Method 1 and click OK.
Method 3: Connect to an instance in another region
To connect to an instance in a different region, click Metadata Management, then click Instances. When configuring the new instance, set Log on After Connection to Yes. For parameter details, see Connect to Instance.
Step 3: Verify the connection
After connecting, the instance appears in the Logged-on Instances list.
What's next
Right-click any instance in the Logged-on Instances list to perform management operations. For more information, see Manage instances.
