Considerations for a high-availability deployment of Infrastructure Management

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.

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.

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.

    Tip

    If you choose to use NGINX as the load balancer, you can use the attached file as a server configuration example.

  • To detect the active and standby nodes, configure the load balancer to check the HTTP response codes for the following URLs:

    https://<primary hostname>/jsp/ShowError.jsp

    https://<secondary hostname>/jsp/ShowError.jsp

    HTTP response 200 - active node
    HTTP response 503 - standby node

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.
