• Process classes can be used as a means to implement high availability:

  • Display feature availability
    StartingFromRelease 1.8

  • A sequence of JobScheduler Agents can be specified that would be checked for availability by the initiating JobScheduler instance at run-time.
  • If a JobScheduler Agent were not avaiable then the next Agent would be selected for execution of a job. The configuration is made from the <remote_schedulers select="first|next"/> attribute.
  • The connection to an Agent makes use of the HTTP or HTTPS protocol; i.e. the remote instance is configured by http://host:port or https://host:port .
• Example

  • Agent Passive Cluster configuration

    Code Block
    language xml title Process class for Use fixed-priority scheduling with Agents collapse true
    <?xml version="1.0" encoding="ISO-8859-1"?> <process_class max_processes="10"/> <remote_schedulers select="first"> <remote_scheduler remote_scheduler="http://Andreas-MacBook-Pro.local:4445" http_heartbeat_timeout="15" http_heartbeat_period="10"/> <remote_scheduler remote_scheduler="http://localhost:4445" http_heartbeat_timeout="15" http_heartbeat_period="10"/> </remote_schedulers> </process_class>

  • Agent Active Cluster configuration

    Code Block
    language xml title Process class for round-robin scheduling with Agents collapse true
    <?xml version="1.0" encoding="ISO-8859-1"?> <process_class max_processes="10"/> <remote_schedulers select="next"> <remote_scheduler remote_scheduler="http://Andreas-MacBook-Pro.local:4445" http_heartbeat_timeout="15" http_heartbeat_period="10"/> <remote_scheduler remote_scheduler="http://localhost:4445" http_heartbeat_timeout="15" http_heartbeat_period="10"/> </remote_schedulers> </process_class>
