Cluster Service Activation Recommendations for IM and Presence Service


Caution

Before you turn on any services for a feature, you must complete all the required configuration on IM and Presence for that feature. See the relevant documentation for each IM and Presence feature.

Before you turn on services in a cluster, review the following table, which provides service recommendations for multinode IM and Presence configurations.

IM and Presence Service Activation Recommendations

Service/Servlet

Recommendations

Database and Admin Services

Cisco AXL Web Service

Following installation, Cisco AXL Web Service is enabled by default on all cluster nodes. Cisco recommends that you always leave the service activated on the IM and Presence Service database publisher node. This ensures that you are able to configure products that are dependent on AXL. If intercluster communication is configured, this service must be enabled on both nodes in the sub-cluster where remote peers are configured to sync from. If this service is not enabled on both nodes presence and IM capabilities will be lost in failover scenarios.

Based on your needs, you can activate or deactivate the service on specific IM and Presence subscriber nodes in Cisco Unified Serviceability under Feature Services.

Cisco Bulk Provisioning Service

  • You turn on the Cisco Bulk Provisioning Service only on the first node.
  • If you use the Bulk Administration Tool (BAT) to administer users, you must turn on this service.

Performance and Monitoring Services

Cisco Serviceability Reporter

 Turn on this service on the publisher node only.
Note   

The service only generates reports on the publisher node even if you turn on the service on other nodes.

IM and Presence Services

Cisco SIP Proxy

Turn on this service on all nodes in the cluster.

Cisco Presence Engine

Turn on this service on all nodes in the cluster.

Cisco Sync Agent

Turn on this service on all nodes in the cluster.

Cisco XCP Text Conference Manager
  • Turn on this service if you deploy the chat feature on IM and Presence.
  • Turn on this service on each node that runs the chat feature.
Note   

The permanent chat feature requires an external database. If you enable the permanent chat feature, you must also configure an external database before starting the Text Conference Manager service. The Text Conference Manager service will not start if the permanent chat feature is enabled and an external database is not configured. See the Database Setup Guide for IM and Presence on Cisco Cisco Unified Communications Manager.

Cisco XCP Web Connection Manager
  • Turn on this service if you integrate web clients with IM and Presence.
  • Turn on this service on all nodes in the cluster.

Cisco XCP Connection Manager
  • Turn on this service if you integrate XMPP clients with IM and Presence.
  • Turn on this service on all nodes in the cluster.

Cisco XCP SIP Federation Connection Manager

 Turn on this service if you deploy any of the following configurations:

  • Interdomain federation over the SIP protocol on IM and Presence. Turn on this service on each node that runs SIP federation.

  • Intercluster deployment between a IM and Presence Release 9.x cluster and a Cisco Unified Presence Release 8.6(x) cluster. Turn on this service on all nodes in the Release 9.x cluster.

Cisco XCP XMPP Federation Connection Manager
  • Turn on this service only if you deploy interdomain federation over the XMPP protocol on IM and Presence.
  • Turn on this service on each node that runs XMPP federation.
Note   

Before you turn on the XMPP Federation Connection Manager service on a node, you must turn on XMPP Federation in Cisco Cisco Unified Communications Manager IM and Presence Administration on that node. See Interdomain Federation for IM and Presence on Cisco Cisco Unified Communications Manager.

Cisco XCP Message Archiver
  • Turn on this service if you deploy the Compliance feature on IM and Presence.
  • Turn on this service on any node that runs the IM Compliance feature.
Note   

If you turn on the Message Archiver before you configure an external database, the service will not start. Also, if the external database is not reachable, the service will not start. See the Database Setup Guide for IM and Presence on Cisco Cisco Unified Communications Manager.

Cisco XCP Directory Service
  • Turn on this service if you integrate XMPP clients on IM and Presence with an LDAP directory.
  • Turn on this service on all nodes in the cluster.
Note   

If you turn on the Directory Service before you configure the LDAP contact search settings for third-party XMPP clients, the service will start, and then stop again. See Configuration and Administration of IM and Presence Service on Cisco Unified Communications Manager.

Cisco XCP Authentication Service
  • Turn on this service if you integrate XMPP clients with IM and Presence.
  • Turn on this service on all nodes in the cluster.
