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_". For example, the diagnostic log for the Reports Group will be diag_AvRepDirSvrSvc_YYYYMMDD_HHMMSS_.txt.
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.
AvCsNodeMgr
The Node Manager service provides the core services for failover. It runs on both the primary and secondary servers, and is responsible for monitoring the status of the servers. It is also responsible for file replication between the servers.
AvDirChangeWriter
The Directory Change Writer service gets messages from the change queue (posted by the AvDSEx55, AvDSAD, and AvDSGlobalCatalog services) and writes them to the Cisco Unity SQL database.
AvDSAD
(Exchange 2000 and Exchange 2003 systems only)
The Active Directory Datastore service monitors the AD for changes in Cisco Unity objects (users, locations, distribution lists, contacts) on domain controllers, 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.
AvDSEx55
(Exchange 5.5 systems only)
The Exchange 5.5 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.
AvDSGlobalCatalog
(Exchange 2000 and Exchange 2003 systems only)
The Global Catalog Datastore service monitors the AD global catalog 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.
AvGaenSvr
The Event Notification utility service polls the Event log and sends e-mail and/or voice mail notifications according to the Event Properties set in the Event Notification Utility Administrator.
Caution We recommend that you use the Event Monitoring System instead of the Event Notification utility.
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.
AvRepDirSvrSvc
The Reports service accepts report requests from the Cisco Unity Administrator, extracts data from log files, and obtains dynamic information from Cisco Unity components such as the DOH and Miu. The Reports service also handles report queuing and canceling.
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
When the message store is not functioning, The Unity Messaging Repository (UMR) service places voice messages left by unidentified callers—an outside caller or a caller from inside the organization calling from a phone that is not associated with a subscriber account (such as a conference room)—in the UnityMTA directory. UMR lets subscribers listen to these messages and gives them to the message store when it begins functioning again.
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.
Behavior of Cisco Unity Services in a Configuration with Exchange 5.5
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.
