/mcpDescription Service Parameter Specifies the time during which CDR maintenance is performed on an hourly basis. For example, if this parameter is set to 12, CDR maintenance runs every hour for 12 hours, starting at the time that is specified in the Maintenance Time parameter. For example, if the Maintenance Time parameter is set to 7 and this parameter is set to 12, CDR maintenance begins at 7 a.m. and run every hour until 7 p.m. If both parameters are set to 24, CDR maintenance runs every hour all day long. During CDR maintenance, the system deletes the oldest CDRs and associated CMRs. Therefore, the maximum number of records specified in the Max CDR Records parameter is maintained. Also, during maintenance, the system issues an alarm if the CDR file count exceeds 200 and checks for replication links between servers that have been broken, and tries to reinitialize them. Default setting: 2 Minimum: 1 Maximum: 24 Unit: hours Maintenance Window When set to On, collects Database Replication Status summary every day during the Maintenance window and compares the output of three consecutive days to determine if there are tables that have been out of sync for all three days. If that is the case, it triggers an alert. This parameter, by default, is set to Off and runs at the time specified in Maintenance Time parameter. Default: Off Table Out of Sync Detection Sets the Maintenance Task trace. You must turn on this parameter to get a performance counter trace from the Maintenance Task. This is a required field. Default setting: Off MaintenanceTaskTrace Cisco DirSync Specifies the maximum number of LDAP directories (also known as agreements) that can be configured in the LDAP Directory window in Cisco Unified CM Administration (System > LDAP > LDAP Directory). Creating more than one LDAP directory helps in synchronizing users from more than one search base. You must restart the Cisco DirSync service for changes to this parameter to take effect. Note Default setting: 5 Minimum: 1 Maximum: 5 Maximum Number of Agreements Specifies the maximum number of LDAP host names that can be configured for failover purposes. You must restart the Cisco DirSync service for changes to this parameter to take effect. Note Default setting: 3 Minimum: 1 Maximum: 3 Maximum Number of Hosts System Administration Guide 217 System Settings Service Parameters
