IBM Streams 4.2

Adding externally managed resources to an IBM Streams enterprise domain

To add externally managed resources to an enterprise domain, configure the resource manager to allocate resources to the domain.

Before you begin

Set up the external resource manager for IBM® Streams.
If you are using IBM Platform Symphony or a user-defined resource manager, deploy the resource installation package on all of the externally managed resources that you want to add to the enterprise domain.
Note: If you installed the main installation package on a shared file system that is accessible by all resources in the domain, you can skip this step.

Procedure

Configure the external resource manager to allocate resources to the enterprise domain. The way that resources are allocated depends on the resource manager. For more information, see your resource manager documentation.
Optional: Update the domain.managementResourceAllocationTags domain property. The tags that you specify on this property determine which domain management services run on the same externally managed resources.
Both IBM Streams resources and externally managed resources can be used together in a domain. IBM Streams resources that have tags which match resource requests are used first. If additional resources are needed, IBM Streams uses the externally managed resources.

Example: The default value of the domain.managementResourceAllocationTags property is authentication,audit,jmx,sws. For an IBM Streams resource to be selected as a management resource, it must have all of these tags. If the domain.managementResourceAllocationTags property is updated with a value of authentication,audit, an IBM Streams resource must have both the authentication and audit tags to be selected. Additional resources will be requested for the jmx and sws tags that were removed from the property. For an additional IBM Streams resource to be selected, it must have one or both of these tags.

For more information about domain properties, enter streamtool man domainproperties. To update domain properties, you can use the Streams Console or the streamtool setdomainproperty command. For information about the command, enter streamtool man setdomainproperty.

Note: You must restart the domain for the changes to take effect.

What to do next

Create instances and allocate resources to the instances.
