Cisco Unity Services and Their Functions


Cisco Unity Services are the top level components for the diagnostic traces that are used in troubleshooting. When a diagnostic trace is viewed by using the Cisco Unity Diagnostic Tool, the file always contains the Service in the file name immediately following the "diag_".

Table A-1 Cisco Unity Services 

Service
Function

AvCsGateway

The Gateway service provides a secure interface to the Manager (AvCsMgr) service. It allows external processes to query the state of the Manager, start or stop the Manager, or request internal interfaces to the Manager components (if allowed).

AvCsMgr

The Manager service is the primary Cisco Unity service and the core voice messaging system. It runs the CommServer platform components, provides status on the components, and exposes component interfaces to other internal and external components.

AvDirChangeWriter

The Directory Change Writer service gets messages from the change queue (posted by the AvDSDomino service) and writes them to the Cisco Unity SQL database.

AvDSDomino

The Domino Datastore service monitors the Cisco Unity SQL database for changes in Cisco Unity objects (users, locations, distribution lists, contacts) and sends notification of the changes to the Change Writer service. This keeps Cisco Unity synchronized with directory changes made in the Cisco Unity Administrator.

AvLic

The Licensing service provides secure licensing information to Cisco Unity and authenticated clients. In addition, it monitors the Cisco Unity SQL database and provides dynamic utilization information of per-seat licensing features.

AvMMProxySvr

The Media Master Proxy server provides client authentication and anonymous access to media and resource interfaces. Available to anyone, this service provides application-level authentication of clients running on any platform. After authenticating, it then exposes interfaces for streaming WAV files over the phone or to a client platform.

AvMsgStoreMonitorSvr

The Message Store Monitor service watches subscriber mailboxes on the Cisco Unity server for new or deleted messages. This service then adds an MWI request to the Notifier Queue to turn the subscriber message waiting indicator (MWI) on or off. When message notification is enabled, this service adds events for message notifications through pager or message delivery.

AvNotifierMgr

The Notifier Manager provides notification for MWIs and event notifications through the Notifier and NotifyQ components.

AvSqlChangeWriter

The SQL Change Writer service monitors the Cisco Unity SQL database and requests the applicable directory service to update the directory as needed.

AvTtsSvr

The Text to Speech service provides a text-to-audio rendering service that is used by the Call Control/Media (Miu) component to play e-mail messages over the phone.

AvUMRSyncSvr

The AvUMRSyncSvr service is one of the components of the Unity Message Repository (UMR), which is a feature that helps insulate Cisco Unity from volatility in the external network. Voice messages left by unidentified callers are temporarily stored in the UnityMTA directory on the Cisco Unity server. The AvUMRSyncSvr service picks up the messages and hands them off to the message store backend for delivery.

Cisco Unified Performance Information and Diagnostics

The CUPID service gathers performance and diagnostic information about the Cisco Unity server.

CiscoUnityTdsProxy

The CiscoUnityTdsProxy service provides Cisco Unity database access to Cisco Unity processes that are running in a security context that does not have database rights. The service allows connections to be made via ADO, ODBC, JDBC and other standard APIs that use the Microsoft TDS (Tabular Data Stream) protocol.

CsBridgeConnector

The Connector service monitors the UOmni mailbox and synchronizes directory information in both directions between Cisco Unity and an Octel Node (the Bridge).

CsEmsSvc

The Event Monitoring Service polls the Event log and sends e-mail and/or voice mail notifications according to the settings for the events and recipients in the Event Monitoring Service window.

RSKDataService

The Remote Serviceability Kit Data service collects the information for the Cisco Unity SNMP extension agent in response to SNMP requests for Cisco Unity objects.


Behavior of Cisco Unity Services in a Configuration with Domino

Services that log on with the account that owns the Cisco Unity directory and message store services are listed as logging on as UnitySvc, the suggested Active Directory user logon name.

AvCsGateway

MSSQLSERVER

Automatic

UnitySvc

Critical; must be restarted if stopped.

Starts and stops AvCsMgr.

AvCsMgr

Dialogic System Service, MSSQLSERVER, Telephony

Manual

UnitySvc

Critical; started and stopped by the system tray or the Status Monitor via AvCsGateway.

Can be started only by AvCsGateway; should be stopped by AvCsGateway. If AvCsGateway is started by the Status Monitor, AvCsMgr is also started.

AvDirChangeWriter

Message Queuing, MSSQLSERVER

Automatic

Local system (needs access to SQL)

Critical, must be restarted if stopped.

If stopped, there is no impact on AvCsMgr.

AvDSDomino

MSSQLSERVER, message queuing

Automatic

UnitySvc

Critical, must be restarted if stopped.

AvLic

MSSQLSERVER

Automatic

Local system

 

AvMMProxySvr

Remote Procedure Call (RPC)

Automatic

Local system

Critical; used by web applications and e-mail clients.

AvMsgStoreMonitorSvr

None

Manual

UnitySvc

Critical; used for message notification and MWIs.

AvNotifierMgr

None

Manual

UnitySvc

Critical; used for message notification and MWIs.

AvSqlChangeWriter

MSSQLSERVER

Automatic

Local system

Runs during the MSCW bulk synchronization of all SQL and AD data.

AvTtsSvr

None

Manual

Local system

Not critical.

AvUMRSyncSvr

MSSQLSERVER

Manual

UnitySvc

Critical; must be restarted if stopped; AvCsMgr starts AvUMRSyncSvr during startup if AvUMRSyncSvr is not already running.

If stopped, there is no impact on AvCsMgr, but messages from unidentified callers remain on the Cisco Unity server and are not handed off to Domino for delivery; must be restarted if stopped.

Cisco Unified Performance Information and Diagnostics

None (configurable)

Automatic

Local system

Not critical.

If stopped, there is no impact on AvCsMgr.

CiscoUnityTdsProxy

None

Automatic

Local system

Critical; used by the Cisco Unity Administrator and by the Cisco Personal Communications Assistant.

CsBridgeConnector

(always installed, but started only if the Bridge is licensed)

MSSQLSERVER

Manual

UnitySvc

Not critical; can be disabled if the Bridge is not used; does not start if no Bridge ports are licensed.

If stopped, there is no impact on AvCsMgr, but the Bridge does not function.

CsEmsSvc

(not registered as a service until configured)

None

Manual

UnitySvc

Not critical.

If stopped, there is no impact on AvCsMgr.

RSKDataService

(not registered as a service until configured)

None

Automatic

Local system

Not critical.
