• Visibility: Public
  Change Control: StableDetails:
  • PBS does not allow attributes like scheduling, scheduler_iteration to be set on PBS server object.
  • scheduling and scheduler_iteration now belong to the sched object
    • During failover when secondary server takes control it will try to connect to connect to schedulers by using their host attribute.
      
      • If secondary server is unable to connect to scheduler running on remote host then it will start that scheduler locally and update it's "host" attribute.
      • When Primary pbs server takes control from secondary it will always check if scheduler's host attribute matches it's server name, if it doesn't then it will shutdown the remote scheduler and spawn it locally on primary server.
    • If set at the server level, the changes will be applied to the default sched object
  • As backward compatibility PBS still allows attributes like scheduling, scheduler_iteration to be set on PBS server object. Any changes made to these attributes are automatically reflected in scheduler object. Similarly if any changes are made to these attributes in scheduler object, they are automatically reflected in the server object.
  • If at any point in time if Server is not able to contact or reach the corresponding scheduler one of the following messages are shown in server_logs.
           Unable to reach scheduler associated with partitionpartition [<partition id>]
           Unable to reach scheduler associated with job <job id>
