Cisco Unity Services


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 service. It allows external processes to query the state of the Manager, start or stop the Manager, or request internal interfaces to Manager components (if allowed).

AvCsMgr

The Manager service is 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 server.

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 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 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 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.

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.

AvTtsSvr

The Text-to-speech service provides a text-to-audio rendering service that is used by the Call Control/Media (Miu) component.

AvUMRSyncSvr

The Unity Messaging Repository (UMR) service places the initial voice messages left by outside callers in the UnityMTA directory.

CsBridgeConnector

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