Configuring server groups

A server group consists of one or more servers that share the same database and are designated as part of a server group. Server groups are designed to provide failover operations for crucial operations. They can also provide scalability and load balancing.

To ensure high availability of BMC Remedy AR System operations, you can set up a server group to provide failover protection by assigning rankings to servers in the group for specific BMC Remedy AR System operations. Servers in a server group can provide failover protection for the following functions:

  • Administrative operations
  • Archiving
  • Assignment Engine
  • BMC Atrium CMDB
  • Atrium Integration 
  • BMC Remedy Approval Server
  • BMC Remedy Distributed Server Option (DSO)
  • BMC Remedy Email Engine
  • BMC Remedy Flashboards
  • BMC SLM Collector (a component of BMC Service Level Management)
  • Business Rules Engine (a component of BMC Service Level Management)
  • Escalations
  • Full Text Indexing
  • Reconciliation Engine

A server group can also provide ease of administration because it has only one database to manage and back up. In addition, AR System servers that belong to a server group share all licenses except BMC Remedy AR System server licenses. One server in the group is designated as the administrative server. When you change workflow and applications on this server, the changes are automatically propagated to other servers in the group. In a server group environment, when the Admin server is down and the secondary server has not picked up the Admin server operations, requests pending from Hierarchical Group might accumulate.

You can also configure specific servers in the group to handle reporting, reconciliation, and other tasks that can impact performance, freeing up the remaining servers in the group to handle user traffic.

A server group can provide load balancing for heavy user traffic. You can use a hardware load balancer with a server group to direct user traffic to some or all servers in the group. See Configuring a hardware load balancer with BMC Remedy AR System.

Server group functionality is not supported for multiple servers on one computer, and servers earlier than release 6.0 are not compatible with server groups.

The following topics provide detailed information about how to configure server groups:

    Where is the "Sharing a database without using a server group" paragraph for 9.1 version?

      Hello Rodolfo,

      Sharing a database without using a server group was never supported to a certified scenario, therefore BMC has decided to remove the documentation. This scenario may or may not work and may have issues.

      Regards,

    Hi, those steps (https://docs.bmc.com/docs/ars91/en/understanding-server-group-naming-609071753.html?src=search) do not appear here... maybe they should be added? it is quite confusing. thanks
