Redundant (HA) SNMP Master Agents

The Management Layer supports configuration with a redundant pair of SNMP master agents. Redundant configuration assumes the presence of two SNMP master agent applications, one primary and one backup. When Solution Control Server loses a connection with the primary SNMP master agent, SCS switches all NMS communications to the backup SNMP master agent.

If your SNMP master agent application can operate in a redundant mode (as does, for example, Genesys SNMP Master Agent), and you would like to deploy this configuration, follow the instructions in this section.

Redundancy

Redundant SNMP Master Agents support only the warm standby redundancy type.

Deploying Redundant SNMP Master Agents

This section describes how to install and set up redundant SNMP Master Agents.

Installation Recommendations

If you are installing the primary and backup SNMP Master Agents on the same host computer:

  • Install them in different directories.
  • Specify a different port number for each server.

Prerequisites

Installation and Configuration

Tip
(Optional) If the backup SNMP Master Agent is to reside on a remote Host, you can deploy it to that Host using Genesys Administrator Extension. Refer to ''Framework 8.1 Genesys Administrator Extension Help'' for instructions.
1. Configure an Application object for the backup SNMP Master Agent. [+] Show steps
2. If you did not deploy the backup SNMP Master Agent to a remote site using Genesys Administrator Extension, install it now.
3. Modify the primary SNMP Master Agent Application object to work with the backup SNMP Master Agent. [+] Show steps
4. If you installed the backup SNMP Master Agent on UNIX, check the run.sh file and modify it, if necessary, so the application can be started properly. [+] Show steps

Starting the Backup SNMP Master Agent

Important
Once installed, the two SNMP Master Agents must be started from the same account.

When starting a backup SNMP Master Agent, be sure to use the following command-line options:

-host The name of the host on which Configuration Server is running.
-port The communication port that client applications must use to connect to Configuration Server.
-app The exact name of the backup SNMP Master Agent Application object as configured in the Configuration Database.

For a description of the command-line parameters specific to SNMP Master Agent, refer to SNMP Master Agent.

Starting a Backup SNMP Master Agent on UNIX

Prerequisites

  • The run.sh file has been modified accordingly. See Step 4, above.

Procedure

Do one of the following:

  • To start from Genesys Administrator, refer to Starting and Stopping with the Management Layer.
  • To start manually, go to the directory in which the backup SNMP Master Agent is installed, and do one of the following:
    • To use only the required command-line parameters, type the following command line:
      sh run.sh
    • To specify the command line yourself, or to use additional command-line parameters, type the following command line:
      gsnmpmasteragent -host <Configuration Server host> -port <Configuration Server port> -app <backup SNMP Master Agent Application> [<additional parameters and arguments as required>]

Starting the Backup SNMP Master Agent on Windows

Do one of the following:

  • To start as a Windows Service, refer to Starting and Stopping with Windows Services Manager.
  • To start from Genesys Administrator, refer to Starting and Stopping with the Management Layer.
  • To start manually, do one of the following:
    • Use the Start > Programs menu.
    • To use only the required command-line parameters, go to the directory in which the backup SNMP Master Agent is installed, and double-click the file startServer.bat.
    • To specify the command line yourself, or to use additional command-line parameters, open the MS-DOS window, go to the directory in which the backup SNMP Master Agent is installed, and type the following command line:
      gsnmpmasteragent.exe -host <Configuration Server host> -port <Configuration Server port> -app <SNMP Master Agent Application> [<additional parameters and arguments as required>]
