Cluster Service Activation Recommendations for Cisco Unified Communications Manager

Before you activate services in a cluster, review the following table, which provides service recommendations for multiserver Cisco Unified Communications Manager configurations.

Cisco Unified Communications Manager Service Activation Recommendations

Service/Servlet

Activation Recommendations

CM Services

Cisco CallManager

This service supports Cisco Unified Communications Manager.

In the Control Center - Network Services, ensure that the Cisco RIS Data Collector service and Database Layer Monitor service are running on the node.

Tip    Before you activate this service, verify that the Cisco Unified Communications Manager server displays in the Cisco Unified Communications Manager Find/List window in Cisco Unified Communications Manager Administration. If the server does not display, add the Cisco Unified Communications Manager server before you activate this service. For information on how to add the Cisco Unified Communications Manager server, see the Cisco Unified Communications Manager Administration Guide.

Cisco Messaging Interface

Activate only if using an SMDI integration to a third-party Voicemail system using a server-attached USB-to-serial adapter.

Cisco Unified Mobile Voice Access Service

For mobile voice access to work, you must activate this service on the first node in the cluster after you configure the H.323 gateway to point to the first VXML page. In addition, make sure that the Cisco CallManager and the Cisco TFTP services run on one server in the cluster, not necessarily the same server where the Cisco Unified Mobile Voice Access Service runs.

Cisco IP Voice Media Streaming App

If you have more than one node in the cluster, activate on one or two servers per cluster. You may activate on a node that is dedicated specifically for music on hold. This service requires that you activate Cisco TFTP on one node in the cluster. Do not activate this service on the first node or on any nodes that run the Cisco CallManager service.

Cisco CTIManager

Activate on each node to which JTAPI/TAPI applications will connect. CTIManager activation requires the Cisco CallManager service also to be activated on the node. See topics related to CM services for more information on CTIManager and Cisco CallManager services interaction.

Cisco Extension Mobility

Activate on all nodes in the cluster.

Cisco Extended Functions

Activate this service, which supports the Quality Report Tool (QRT), on one or more servers that run the Cisco RIS Data Collector. Make sure that you activate the Cisco CTIManager service on a node in the cluster.

Cisco DHCP Monitor Service

When the DHCP Monitor service is enabled, it detects changes in the database that affect IP addresses for the IP phones, modifies the /etc/dhcpd.conf file, and stops and restarts the DHCPD daemon with the updated configuration file. Activate this service on the node that has DHCP enabled.

Cisco Location Bandwidth Manager

If you plan to use Cisco Location Call Admission Control functionality to manage bandwidth allocation for audio and video calls, you must activate this service. This service works in conjunction with the Cisco CallManager service. It is recommended to run the Cisco Location Bandwidth Manager on the same server that runs the Cisco CallManager service. If the Location Bandwidth Manager is not running on the same server as the CallManager service, ensure that you configure the Location Bandwidth Manager Group correctly.

Cisco Intercluster Lookup Service

If you plan to propagate the URI and numeric routing information between multiple Cisco Unified Communications Manager clusters, you must activate this service on the publisher of the cluster that participates in this exchange.

Cisco Dialed Number Analyzer Server

If you have more than one node in the cluster, activate this service on one node that is dedicated specifically for the Cisco Dialed Number Analyzer service.

Cisco Dialed Number Analyzer

If you are planning to use Cisco Unified Communications Manager Dialed Number Analyzer, activate this service. This service may consume a lot of resources, so only activate this service on the node with the least amount of call-processing activity or during off-peak hours.

Cisco TFTP

If you have more than one node in the cluster, activate this service on one node that is dedicated specifically for the Cisco TFTP service. Configure Option 150 if you activate this service on more than one node in the cluster.

CTI Services

Cisco IP Manager Assistant

If you are planning to use Cisco Unified Communications Manager Assistant, activate this service on any two servers (Primary and Backup) in the cluster. Ensure that Cisco CTI Manager service is activated in the cluster. See the Cisco Unified Communications Manager Features and Services Guide for other recommendations.

Cisco WebDialer Web Service

Activate on one node per cluster.

Self-Provisioning IVR

To enable the Self-Provisioning IVR service, you must also enable the Cisco CTI Manager service.

You can configure self-provisioning even if the service is deactivated, but the administrator cannot assign IP phones to users using the IVR service. By default, this service is deactivated.

CDR Services

Cisco SOAP-CDRonDemand Service

You can activate the Cisco SOAP-CDROnDemand Service only on the first server, and it requires that the Cisco CDR Repository Manager and Cisco CDR Agent services are running on the same server.

Cisco CAR Web Service

You can activate the Cisco CAR Web Service only on the first server, and it requires that the Cisco CAR Scheduler service is activated and running on the same server and that the CDR Repository Manager service also is running on the same server.

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 publisher node. This ensures that you are able to configure products that are dependent on AXL, such as Unified Provisioning Manager.

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

Cisco Bulk Provisioning Service

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

Cisco UXL Web Service

This service performs authentication and user authorization checks. The TabSync client in Cisco IP Phone Address Book Synchronizer uses the Cisco UXL Web Service for queries to the Cisco Unified Communications Manager database.

If you plan to use the Cisco IP Phone Address Book Synchronizer, you must activate this service on one node, preferably publisher. If you are not using Cisco IP Phone Address Book Synchronizer, then Cisco recommends that you deactivate this service . By default, this service is deactivated.

Cisco Platform Administrative Web Service

You must activate this service if you plan to use a Cisco Prime Collaboration Deployment (PCD) server to manage upgrades, switch version, restart or readdress operations. Platform Administrative Web Service (PAWS) allows SOAP communication between the Call Manager and Prime Collaboration Deployment (PCD). If you have more than one node in the cluster, you must activate this service on each server in the cluster.

Cisco TAPS Service

Before you can use the Cisco Unified Communications Manager Auto-Register Phone Tool, you must activate this service on the first node. When you create dummy MAC addresses for the Cisco Unified Communications Manager Auto-Register Phone Tool, ensure that the Cisco Bulk Provisioning Service is activated on the same node.

Performance and Monitoring Services

Cisco Serviceability Reporter

Activate on only the first node.

Note   

The service only generates reports on the first node even if you activate the service on other nodes.

Cisco CallManager SNMP Service

If you use SNMP, activate this service on all servers in the cluster.

Security Services

Cisco CTL Provider

Activate on all servers in the cluster.

Cisco Certificate Authority Proxy Function (CAPF)

Activate on only the first node.

Directory Services

Cisco DirSync

Activate only on the first node.
