/mcpFor more information about Cisco Unified Serviceability services, see the Cisco Unified Serviceability Administration Guide Release 10.0(1), available at http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/service/10_0_1/admin/CUCM_BK_CDDBCDEB_00_cisco-unified-serviceability-merge-100.html. Some changes to service parameters can cause system failure. You should not make any changes to service parameters unless you fully understand the feature that you are changing or unless the Cisco Technical Assistance Center (Cisco TAC) specifies the changes. Caution The Table 16-2 describes the service parameters that can be modified for Unity Connection. The fields not described in this table are managed from Cisco Unified Communications Manager. Service Parameter Descriptions Description Service Parameter Cisco AMC Service Specifies the Primary AMC (AlertMgr and Collector) server that collects clusterwide real-time information. Value must match one of the configured servers and, preferably, a server with no or minimal call processing. Primary Collector Specifies the Failover AMC (AlertMgr and Collector) server. The server specified in this parameter is used to collect real-time data when the Primary AMC is down or unreachable. No data is collected if Failover Collector is not specified when Primary Collector is not active. Failover Collector Determines whether collecting and alerting of real-time cluster information is enabled (True) or disabled (False). Default setting: True Data Collection Enabled Specifies the AMC collecting rate, in seconds. Default setting: 30 Minimum: 15 Maximum: 300 Unit: seconds Data Collection Polling Rate Specifies the amount of time, in seconds, that backup AMC (AlertMgr and Collector) waits at startup in order to determine if primary AMC is up and actively collecting. This parameter prevents backup AMC from assuming a collecting task prematurely. Restart the AMC service on the backup server for the parameter change to take effect. Note Default setting: 60 Minimum: 15 Maximum: 300 Unit: seconds Server Synchronization Period Specifies the port number to turn on RMI registry. This port is used for primary or backup AMC to locate other AMC and for the RTMT servlet to find primary/backup AMC. Restart the AMC service for the parameter change to take effect. Note Default setting: 1099 Minimum: 1024 Maximum: 65535 RMI Registry Port Number System Administration Guide 215 System Settings Service Parameters
