Hologres:Manage instances

Overview

HoloWeb lets you manage both logged-off and logged-on instances through a right-click context menu on the Metadata Management tab. The available operations depend on the instance state and network type.

Prerequisites

Before you begin, ensure that you have:

• A Hologres instance (logged-off or logged-on) in your Alibaba Cloud account

• Access permissions to the target instance in the current region

Manage logged-off instances

When you activate a Hologres engine instance, the system automatically creates a logged-off instance of VPC network type. This auto-created VPC instance appears in the list with a icon. You cannot edit its details or delete it.

To manage a logged-off instance:

1. Log on to the Hologres Management Console.

2. In the navigation pane on the left of the top menu bar, select the desired region.

3. Click Go to HoloWeb to open the HoloWeb development page.

4. On the Metadata Management tab, right-click the target logged-off instance.

   

   The logged-off instances section lists all instances in the current region that your Alibaba Cloud account has access permissions to.

   Select one of the following operations:

   • Connect to Instance — Logs on to the instance and moves it to the logged-on instances list. For details, see Log on to an instance.

   • Edit Instance — Opens the instance configuration page. Editable parameters vary by network type: For a description of each parameter, see Edit instance parameter description.

     • Public network-type instances: all parameters are editable.

     • VPC-type instances: only the Description field is editable.

   • Delete Instance — Deletes the instance. After confirming the instance information, click OK

   Only public network-type instances () can be deleted. VPC-type instances () cannot be deleted.

Manage logged-on instances

To manage a logged-on instance:

1. Log on to the Hologres Management Console.

3. Click Go to HoloWeb to open the HoloWeb development page.

4. On the Metadata Management tab, right-click the target logged-on instance.

   When you activate a Hologres engine instance, the system automatically creates a logged-off instance of VPC network type, displayed with a icon. You cannot edit its details or delete it.

   Select one of the following operations:
