IBM Streams 4.3.0
Administering resources
After you add resources to domains and instances, you can administer them by using the Streams Console or the streamtool command-line interface.
- Resource allocation for application services
A resource for application services can be static (added explicitly to an instance) or dynamic (added to or removed from an instance dynamically based upon the job or processing element requirements). A static resource is specified manually by name or automatically by a resource specification and remains allocated to the instance until it is explicitly removed. A dynamic resource is released from the instance when the instance is stopped or when the resource is no longer needed. - Resource allocation for management services
Management services are placed on static resources if available. If the instance does not have any static resources and dynamic resource allocation is enabled, management resources are dynamically requested at the time the instance is started. - Resource identifiers
A resource identifier uniquely identifies a resource in a domain or instance. - Tags
Tags are a mechanism for differentiating and identifying resources that have different physical characteristics or logical uses. - Monitoring resources
Use the Streams Console to view the status of resources. - Stopping and quiescing resources
You can stop or quiesce resources when you want to perform maintenance activities. - Removing resources
You might choose to remove a resource if the host is no longer available or you want to replace it with a different resource.
