Welcome to the HCL Domino 11.0.1 documentation
Welcome to the HCL Domino® 11.0.1 documentation. Here administrators can find information about planning, installing, configuring, and administering Domino 11.0.1.
Administering
This documentation provides information about the administration tools for managing and monitoring servers and databases.
Monitoring
This section describes how to use the tools and features that help you monitor a Domino® system.
Monitoring quality of service
Quality of Service, or QoS, is designed to react to the general operation of a Domino® server in order to keep that server functioning reliably and always available. If QoS detects that a server is not responding or hung, QoS probing can be configured to email an administrator about the problem and/or automatically terminate the server and restart it. QoS log information can also be useful for analysis by Support.
Limiting QoS restarts
QoS provides the option to limit the QoS restart times during one interval. When the restart times reach the time limitation, the QoS service is deactivated.

  Learn about all of the new features for administrators in HCL Domino® 11.
- Overview
  Welcome to HCL Domino® Administrator Help.
- Domino trial
  A trial version of HCL Domino® 11.0.1 is available free of charge.
- Installing
  Use this documentation to install the HCL Domino® server and subsequently deploy the HCL Notes®client.
- Planning
  Use this topic as an overview of planning task.
- Configuring
  Use this information to configure your network, users, servers (including Web servers), directory services, security, messaging, widgets and live text, and server clusters.
- Securing
  This section describes security features, including execution control lists, IDs, and SSL.
- Administering
  This documentation provides information about the administration tools for managing and monitoring servers and databases.
  - Administration tools
    Topics in this section describe the tools you can use to administer a Domino® server.
  - Monitoring
    This section describes how to use the tools and features that help you monitor a Domino® system.
    - Monitoring the Domino® system
      You can monitor system activity and platform use using one of three tools -- the Domino® Administrator, the Web Administrator, or the server console.
    - Server Health Monitor
      You can monitor and troubleshoot performance issues using a number of different tools.
    - Domino® domain monitoring (DDM)
      Domino® domain monitoring (DDM) provides one location in the Domino Administrator client that you can use to view the overall status of multiple servers across one or more domains, and then use the information provided by DDM to quickly resolve problems.
    - The Domino® SNMP Agent
      The Domino® SNMP Agent enhances the monitoring and control features of Domino by enabling third-party management stations, which use industry standard SNMP, to manage aspects of the Domino server.
    - Overview of server maintenance
      As a Domino® administrator, a major part of your job is maintaining each server that you administer.
    - Tools for mail monitoring
      Domino® provides three tools that you can use to monitor mail. Message tracking allows you to track specific mail messages to determine if the intended recipients received them. Mail usage reports provide the information you need to resolve mail problems and improve the efficiency of your mail network. Mail probes test and gather statistics on mail routes.
    - Monitoring directory assistance
      You can monitor directory assistance by using Show Xdir command to display information about all the directories a server uses for directory services. You can also view directory assistance statistics.
    - Monitoring databases
      You can monitor database activity, replication, and document deletions.
    - Monitoring a cluster
      Domino® provides several ways to find out what is happening in a cluster and make adjustments to keep the cluster running smoothly and efficiently, so that no server is overloaded. You can monitor failover, workload balancing, and cluster replication to see how efficiently the cluster is running.
    - Monitoring slow or unresponsive servers with the Domino® Diagnostic Probe
      Use the Domino® Diagnostic Probe (DDP), a Java™ utility provided by Support, to monitor servers that have been intermittently slow or unresponsive. The probe is a Java process (dbopen.jar) that runs in the background. The utility probes a specific Domino server over time by invoking database open transactions. If the probe detects a slow response, it will invoke Notes® System Diagnostic (NSD) to gather diagnostic data. This data is used by Support to troubleshoot and determine the cause or causes of the performance degradation.
    - Monitoring quality of service
      Quality of Service, or QoS, is designed to react to the general operation of a Domino® server in order to keep that server functioning reliably and always available. If QoS detects that a server is not responding or hung, QoS probing can be configured to email an administrator about the problem and/or automatically terminate the server and restart it. QoS log information can also be useful for analysis by Support.
      - Enabling QoS when starting Domino®
        You enable QoS at a command prompt.
      - Limiting QoS restarts
        QoS provides the option to limit the QoS restart times during one interval. When the restart times reach the time limitation, the QoS service is deactivated.
      - Pausing and resuming QoS
        QoS provides a mechanism to pause or resume the QoS service at a specific time. Pausing QoS avoids allowing the server to be killed during an option that is expected to take a long time or that is critical to server operation; examples are backups or other maintenance operations. Temporarily disabling QoS allows these operations to complete without being misinterpreted by QoS as a server problem.
      - Running QoS with a no kill option
        You can run QoS with a no kill option. When QoS detects server exceptions, it sends a single email to a specified administrator with notification of the exception instead of killing and restarting the server directly. (You can also set QoS to send mail to an administrator whether or not you enable the no kill option.)
      - Running QoS with other configuration options
        You can run QoS with several additional options to disable probing and manage timeouts.
      - Verifying that QoS is running
        If you are the not the administrator who enabled QoS, you can verify the correct setup.
    - Understanding Quality of Service (QoS) behavior and logging
      This topic covers details of QoS including server and server controller behavior during kill events, failover trigger, and log file content.
  - Managing servers
    Manage Domino® servers by performing any of these tasks.
  - Managing databases
    Topics in this section describe how to set up and manage Domino® databases.
- Tuning
  Use this information to improve HCL Domino® server, Domino Web server, and messaging performance through the use of resource balancing and activity trends, Server.Load commands, advanced database properties, cluster statistics, and the Server Health Monitor.
- Troubleshooting
  This section describes how to find and solve problems with HCL Domino® server and Administrator client.

Limiting QoS restarts

QoS provides the option to limit the QoS restart times during one interval. When the restart times reach the time limitation, the QoS service is deactivated.

Procedure

Set the following parameters in the dcontroller.ini file.

QOS_RESTART_LIMIT_ENABLE=n
Determines whether to enable the restart limitation. The default is 0.
QOS_RESTART_LIMIT_MAXIMUM=n
Sets the maximum restart times during specific interval (set by QOS_RESTART_LIMIT_PERIOD). The default is 3.
QOS_RESTART_LIMIT_PERIOD=n minutes
Restart time limitation interval; QoS allows only the restart times during this period. The default is 30 minutes.
