/mcpDescription Service Parameter Specifies the delay in starting the directory synchronization process after the Cisco DirSync service starts. Directory synchronization ensures that the users in the LDAP server are copied to the Cisco Unified Communications Manager database. Note You must restart the Cisco Tomcat service for changes to this parameter to take effect. Default setting: 5 Minimum: 5 Maximum: 60 Delayed Sync Start Time (mins) Cisco RIS Data Collector Parameters Specifies the static TCP port that the Cisco RIS Data Collector services in the cluster use to communicate with each other. This is a required field. Note Restart the Cisco RIS Data Collector service on each server in the cluster for the parameter change to take effect. Default setting: 2555 Minimum: 1024 Maximum: 65535 RIS Cluster TCP Port Specifies the static TCP port that the RIS clients use to communicate with the Cisco RIS Data Collector services in the cluster. Note: You must restart Cisco Database Layer Monitor service and the Cisco RIS Data Collector service on each server in the cluster for the parameter change to take effect. Note Restart Cisco Database Layer Monitor service and the Cisco RIS Data Collector services on each server in the cluster for the parameter change to take effect. Default setting: 2556 Minimum: 1024 Maximum: 65535 RIS Client TCP Port Specifies the time (in seconds) that a RIS client waits for a reply from the Cisco RIS Data Collector service. The RIS Data Collector service running on each server internally distributes 90 percent of the value specified in this parameter. To set this parameter correctly for a cluster with multiple servers, specify a value that is 4 times (or more) the number of servers that are running the RIS Data Collector service in your cluster. Choosing a higher value helps ensure that the RIS Data Collector service on one server has enough time to receive a reply from the RIS Data Collector service on another server. The time needed for a reply can vary based on factors such as the processor speed of the server, number of devices registered to the server, amount of server memory, the volume of calls, and other performance-affecting factors.
