Managing instances

You can use the console to manage virtual application instances, virtual system instances, classic virtual system instances, virtual machine instances, shared service instances, and database instances that are deployed in your cloud.

Before you begin

You can manage instances in two ways:
  • To manage individual types of instances (virtual application, virtual system, classic virtual system, virtual machine, shared service, and databases) that are deployed in your cloud, use the Instances menu and select the appropriate instance type; for example, click Patterns > Virtual Application Instances.. If you are on 2.3.3.3 or later, navigate to Patterns > Manage > Virtual Application Instances.
  • To manage all instances from the Instance Dashboard, use the following procedure.
Important: After deployment, the network is set up for the virtual machines in an instance. Do not reconfigure the network configuration for the virtual machine. Changing the network configuration might cause Cloud Pak System to not be able to reach the virtual machine by its IP address.

The maestro module is used in lifecycle Python scripts for nodeparts and parts. The maestro agent, which downloads and installs parts, and runs the part lifecycle scripts, is installed on each virtual machine in the instance. Each instance has only one master agent. This master agent is in charge of the communication to Cloud Pak System and distributes operations between the virtual machines in the same instance. The master agent virtual machine is randomly elected between all the virtual machines in this instance.

About this task

You must be assigned one of the following roles to perform this procedure:
  • Workload resources administration role with permission to Manage workload resources (Full permission)
  • Workload resources administration role with permission to View all workload resources (Read-only)

Procedure

  1. Click Patterns > VIEW ALL. If you are on 2.3.3.3 or later, navigate to Patterns > Manage > Instance Dashboard. The Instance Dashboard is displayed, organized by instance type:
    • Virtual Applications
    • Virtual Systems
    • Virtual Systems (Classic)
    • Shared Services
    • Databases
  2. Expand the section for the instance type that you want to view. When you expand an instance section, the details display in table format with an instance name, status, the user that created the instance, and the date and time when the instance was created and updated.

    You can click any entry in one of these instance tables to be redirected to another page showing detailed information about the selected instance.

What to do next

Optionally, you can deploy a new instance. You can use one of two methods to do so:
  • In the Instance Dashboard, click Deploy a new instance and select an instance type for deployment.
  • See the Related tasks section for information about deploying one of the following types of instances:
    • Virtual applications
    • Virtual systems
    • Virtual systems (classic)
    • Shared services
    • Databases
