Pool Manager (PMGR)

Pool manager (PMGR) is a process that runs on the MPS common component. PMGR

provides a facility to configure MPS resources into pools. An application can request a

given type of resource from a configured pool, or a specific instance of the resource

class. Even if a specific resource instance is requested and is not available, PMGR can

allocate another instance of the resource class from a configured pool.

In order for a resource to be available for configuration, allocation, or statistics

collection by PMGR, the resource must be registered with PMGR by a resource

provider. A resource provider is any process that manages resources. For example,

CCM provides phone lines as resources. Resource providers automatically detect

what resources are available upon system startup and registers those resources with

PMGR.

Terminology

Resource Object

A reusable hardware (physical) or software (logical) entity that can be used by an

application to perform a particular task. Commonly and simply referred to as 'a

resource'. A resource object has the following attributes that define it:

Allocation/Deallocation

Allocation is the process by which PMGR makes a resource object available to an

application. Once a resource is allocated to an application, that application becomes

the owner of that resource and the resource is unavailable for allocation to other

applications. The owner application must (implicitly or explicitly) deallocate the

resource before exiting. Once a resource is deallocated, PMGR returns it to the pool

in which it is configured, making the resource available for allocation to another

application.

Resource Object Attributes

Attribute Description

rsrcClass The type of resource (e.g., line, app, dtmf, tgen, etc.).

Sometimes referred to as the resource base class.

rsrcInst The instance (number) of this resource class. Needed for

resource objects that have the same rsrcClass. The

instance must be unique for each resource object of the

same rsrcClass in the same component.

rsrcCompType The type of component providing the resource (e.g., mps,

oscar, etc.).

rsrcCompId The resource component identifier (number).
