System Management and Maintenance

The Polycom RealPresence DMA system requires relatively little ongoing maintenance beyond monitoring the status of the system and downloading backups and other data you want to archive. All system management and maintenance tasks can be performed in the management interface. See the appropriate topic for your user role:

Administrator Responsibilities

As a Polycom RealPresence DMA system administrator, you are responsible for the installation and ongoing maintenance of the system. You should be familiar with the following configurations, tasks, and operations:

Installing licenses when the system is first installed and when additional call capacity is added.

Monitoring system health and performing the recommended regular maintenance. See Recommended Regular Maintenance.

Using the system tools provided to aid with system and network diagnostics, monitoring, and troubleshooting. See Troubleshooting Utilities. Should the need arise, Polycom Global Services personnel may ask you to run these tools.

Upgrading the system when upgrades/patches are made available. See Upgrading the Software.

Administrator 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 calls and conferences on the system. Many of these operations will require a system restart to complete, which will result in these calls and conferences being dropped. Before performing these operations, busy out all MCUs and wait for all conferencing activity to cease.

Before you reconfigure, install an upgrade, or restore a backup, manually create a new backup. 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 two or more DNS servers in your network configuration. This allows the Polycom RealPresence DMA 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 three. 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 Polycom RealPresence DMA 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. See Configure Logging Settings. These settings affect the number and the contents of the log archives available for download from the system. See System Log Files. 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. See History Retention Settings. These settings affect how much system activity history is retained on the system and available for download as CDRs. See Call History, Conference History, and Call Detail Records.

Auditor Best Practices

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

Unless otherwise instructed by Polycom Global Services, configure logging at the debug level with a rolling frequency of every day and a retention period of 60 days. If hard drive space becomes an issue, decrease the retention period incrementally until the disk space issue is resolved.

Download log archives regularly and back them up securely (preferably offsite as well as onsite). Delete downloaded log archives to free up disk space.

Export CDRs regularly and back them up securely (preferably offsite as well as onsite).

Provisioner Responsibilities

As a Polycom RealPresence DMA system provisioner, you have access to many of the same features and functions as the system administrator (see User Roles and Access Privileges). Your responsibilities depend on your organization’s policies and the tasks delegated to you by the system administrator. For instance, you may be delegated responsibility for some of the following:

Managing and monitoring users’ conference rooms. See Users.

Managing and monitoring registered endpoints. See Endpoints.

Monitoring active calls. See Active Calls.

Monitoring system health and network usage. See Check General System Health and Capacity.

Monitoring call, conference, and registration history. See Call History, Conference History, and Registration History.

Downloading network usage data at the appropriate intervals. See Check Network Usage Data Export and Export Network Usage Data.

Downloading detailed call and conference history data at the appropriate intervals. See CDR Export and Call Detail Records.
