    With TrueSight Infrastructure Management high-availability (HA), you can minimize the downtime of your monitoring infrastructure. HA is a redundancy operation that eliminates a single point of failure by automatically switching to a standby node if the active node fails or is temporarily shut down. The TrueSight Presentation Server communicates to the HA-enabled Infrastructure Management server through a load balancer.

    Installing and configuring the Infrastructure Management server for application high-availability

    Consider the following requirements before you configure HA for Infrastructure Management.

    ComponentPrerequisites


    Database

    • Application-level HA is supported only with an Oracle database. You cannot configure application-level HA with the embedded SAP SQL Anywhere database. If you are using the embedded SAP SQL Anywhere database, consider the HA cluster mode.
    • BMC recommends that you use Oracle RAC.
    • The Infrastructure Management servers and the Oracle server must reside on the same network.

    TrueSight Operations Management components
    • TrueSight Presentation Server version 10.7 and later.
    • Two TrueSight Infrastructure Management servers version 10.7 and later, designated as the primary and secondary Infrastructure Management servers.
    • The primary and secondary Infrastructure Management servers must have identical hardware and operating system configuration.
      See the hardware and operating system requirements.

    Third-party load balancer

    • A third-party load balancer with reverse proxy configuration support.
    • If using a software-based load balancer, you must install it on a separate server.

    • Configure the load balancer such that the active node is determined based on the HTTP response of 200 and all data is routed to it.

    Network

    Ensure that:

    • Latency between the nodes is consistently not more than 20 ms
    • A minimum bandwidth of 20 Mbps is available at all times

    Ensure that the following ports are available.
