Cisco Login Datastore
The Cisco Login Datastore is a real-time database for storing client sessions to the Cisco Client Profile Agent.
Cisco Route Datastore
The Cisco Route Datastore is a real-time database for storing a cache of route information and assigned users for the Cisco SIP Proxy and the Cisco Client Profile Agent.
Cisco Config Agent
The Cisco Configuration Agent is a change-notification service that notifies the Cisco SIP Proxy of configuration changes in the IM and Presence Service IDS database.
Cisco Sync Agent
The Cisco Sync Agent keeps IM and Presence data synchronized with Cisco Unified Communications Manager data. It sends SOAP requests to the Cisco Unified Communications Manager for data of interest to IM and Presence and subscribes to change notifications from Cisco Unified Communications Manager and updates the IM and Presence IDS database.
Cisco OAM Agent
The Cisco OAM Agent service monitors configuration parameters in the IM and Presence Service IDS database that are of interest to the Presence Engine. When a change is made in the database, the OAM Agent writes a configuration file and sends an RPC notification to the Presence Engine.
Cisco Client Profile Agent
The Cisco Client Profile Agent service provides a secure SOAP interface to or from external clients using HTTPS.
Cisco Intercluster Sync Agent
The Cisco Intercluster Sync Agent service provides the following: DND propagation to Cisco Unified Communications Manager and syncs end user information between IM and Presence Service clusters for intercluster SIP routing.
Cisco XCP Router
The XCP Router is the core communication functionality on the IM and Presence Service server. It provides XMPP-based routing functionality on IM and Presence Service; it routes XMPP data to the other active XCP services on IM and Presence Service, and it accesses SDNS to allow the system to route XMPP data to IM and Presence Service users. The XCP router manages XMPP sessions for users, and routes XMPP messages to and from these sessions.
After IM and Presence Service installation, the system turns on Cisco XCP Router by default.
 Note | If you restart the Cisco XCP Router, IM and Presence Service automatically restarts all active XCP services. Note that you must select the Restart option to restart the Cisco XCP Router; this is not the same as turning off and turning on the Cisco XCP Router. If you turn off the Cisco XCP Router, rather than restart this service, IM and Presence Service stops all other XCP services. Subsequently when you turn on the XCP router, IM and Presence Service does not automatically turn on the other XCP services; you need to manually turn on the other XCP services. |
Cisco XCP Config Manager
The Cisco XCP Config Manager service monitors the configuration and system topology changes made through the administration GUI (as well as topology changes that are synchronized from an InterCluster Peer) that affect other XCP components (for example, Router and Message Archiver), and updates these components as needed. The Cisco XCP Config Manager service creates notifications for the administrator indicating when an XCP component requires a restart (due to these changes), and it automatically clears the notifications after the restarts are complete.
Cisco Server Recovery Manager
The Cisco Server Recovery Manager (SRM) service manages the failover between nodes in a presence redundancy group. The SRM manages all state changes in a node; state changes are either automatic or initiated by the administrator (manual). Once you turn on high availability in a presence redundancy group, the SRM on each node establishes heartbeat connections with the peer node and begins to monitor the critical processes.
Cisco IM and Presence Data Monitor
The Cisco IM and Presence Data Monitor monitors IDS replication state on the IM and Presence Service. Other IM and Presence services are dependent on the Cisco IM and Presence Data Monitor. These dependent services use the Cisco service to delay startup until such time as IDS replication is in a stable state.
The Cisco IM and Presence Data Monitor also checks the status of the Cisco Sync Agent sync from Cisco Unified Communications Manager. Dependent services are only allowed to start after IDS replication has set up and the Sync Agent on the IM and Presence database publisher node has completed its sync from Cisco Unified Communications Manager. After the timeout has been reached, the Cisco IM and Presence Data Monitor on the Publisher node will allow dependent services to start even if IDS replication and the Sync Agent have not completed.
On the subscriber nodes, the Cisco IM and Presence Data Monitor delays the startup of feature services until IDS replication is successfully established. The Cisco IM and Presence Data Monitor only delays the startup of feature services on the problem subscriber node in a cluster, it will not delay the startup of feature services on all subscriber nodes due to one problem node. For example, if IDS replication is successfully established on node1 and node2, but not on node3, the Cisco IM and Presence Data Monitor allows feature services to start on node1 and node2, but delays feature service startup on node3.
Cisco Presence Datastore
The Cisco Presence Datastore is a real-time database for storing transient presence data and subscriptions.
