PMGR

PMGR provides pooled resource management of all resources from Resource

Provider (RP) processes running on the local node. An example of an RP is the CCM

process, which provides lines as resources. An RP registers its resources with PMGR

upon initialization. A registered resource can also be pooled applications (used for call

handoff, for instance). As applications request resources, PMGR allocates the

resources, keeps track of applications and their resources, maintains statistics, and

deallocates resources as necessary.

If PMGR cannot allocate a resource locally, it forwards the request to a remote

instance of PMGR; the specific instance is determined through round-robin

availability. If there are no remote PMGRs available, the request fails. If PMGR dies,

it releases all resources that have been allocated; if an RP dies, it must reconnect to

PMGR to reregister its resources; if an application dies, allocated resources remain

with it: after the application restarts, it queries PMGR for a list of resources currently

allocated to the application; it may then use these resources or free them if no longer

needed.

PMGR associations:

• Connections: Any process that provides resources (RP), applications

• Location: $MPSHOME/bin or %MPSHOME%\bin

• Configuration File: $MPSHOME/common/etc/pmgr.cfg

• SRP Startup File: $MPSHOME/common/etc/gen.cfg

The VSH interface also provides the ability to send commands to PMGR. For a list of

these commands, see the PMGR Commands section in the Avaya Media Processing

Server Series Command Reference Manual.

rpc.riod

The rpc.riod file provides information and access to MPS files for remote

PeriView processes in the SPARC/Solaris environment. rpc.riod is a system

daemon and, as such, only one instance of this process is required for each node.

This file is maintained for backward compatibility for systems running pre-5.4

software. nriod on page 45 is now included with the system to provide Solaris and

Windows functionality.

rpc.riod associations:

• Connections: Any process communicating with the PeriView Task Scheduler

• Location: $MPSHOME/bin

• Configuration File: Not applicable

• SRP Startup File: $MPSHOME/common/etc/gen.cfg

TCAD

TCAD resides in the VOS subcomponent of the MPS component. It provides both
