Polycom CMA System Operations Guide

•Upgrading the system when upgrades/patches are made available. See “Update the Polycom CMA System Software” on page 445.

Administrative Best Practices

The following are some of our recommendations for administrative best practices:

•Perform the recommended regular maintenance.

•Except in emergencies or when instructed to by Polycom Global Services personnel, don’t reconfigure, install an upgrade, or restore a backup when there are active conferences on the system. Many of these operations will require a system restart to complete, which will result in conferences being dropped.

•Before you reconfigure, install an upgrade, or restore a backup, manually create a new backup of the system settings. Then download and archive this backup in the event that something unforeseen occurs and it becomes necessary to restore the system to a known good state.

•For proper name resolution and smooth network operations, configure at least one DNS server in your network configuration, and preferably two or more. This allows the CMA system to function properly in the event of a single external DNS failure.

•Configure at least one NTP server in your time configuration and preferably two or more. Proper time management helps ensure that your cluster operates efficiently and helps in diagnosing any issues that may arise in the future. Proper system time is also essential for accurate audit and CDR data.

Auditor Responsibilities

As a CMA system auditor, you’re responsible for managing the system’s logging and history retention. You should be familiar with the following configurations and operations:

•Configuring logging for the system. These settings affect the number and the contents of the log archives available for download from the system. Polycom Global Services personnel may ask you to adjust the logging configuration and/or download and send them logs.

•Configuring history retention levels for the system. These settings affect how much system activity history is retained on the system and available for download as CDRs.
