Planning for Message Brokers

Planning considerations for the Message Broker include:

  • At least one Message Broker is required for ActiveMQ MPX operation.
  • When the total number of subscribers is relatively low (less than 100 users) and the overall activity is low to moderate (up to 1,000 updates per hour), a single Message Broker can be installed on the same computer as the StarTeam Server.
  • A single Message Broker can fulfill the messaging requirements for multiple configurations (deployed on the same computer or on multiple computers) if the total update volume is low to moderate.
  • To use the same Message Broker for multiple configurations, the connection profiles in each transmitter XML file should point to the same Message Broker (see “Managing the Transmitters”).
  • Subscribers should use a network-near Message Broker if possible. The StarTeam administrator must create MPX profiles to fit the needs of each general location in a distributed group and set one of them as the default profile. Some subscribers can override the default profile and should do that to select a network-near Message Broker.
