• Set the priv directory for the scheduler.
  • The directory must be owned by the sched_user specified while creating scheduler object. It should have permissions set as "750". By default a sched object has 
    it's priv directory set as $PBS_HOME/sched_priv_<sched-name>. If the directory is already used by some other scheduler then error code is set "15216" with error message 
    "Another Sched object also has same value for its sched_log directory"
  • qmgr -c "s sched multi_sched_1 sched_priv=/var/spool/pbs/sched_priv_1"
  • If the priv directory is not accessible by scheduler process, or the scheduler files are not found in the directory, then comment is updated with following error message
    "scheduler can not access it's priv directory"
  Set the log directory for the scheduler. 
  • The directory must be owned by the sched_user specified while creating scheduler object. It should have permissions as "755". By default a sched object has 
    it's logs directory set as $PBS_HOME/sched_logs_<sched_name>. . If the directory is already used by some other scheduler then error code is set "15215"  with error message
    "Another Sched object also has same value for its sched_priv directory"
  • qmgr -c "s sched multi_sched_1 sched_log=/var/spool/pbs/sched_logs"
  • If the log directory is not accessible by scheduler process, or the scheduler files are not found in the directory, then comment is updated with following error message
    "scheduler can not access it's log directory"
  • By default a multi-sched object has scheduling set as False.
    qmgr -c " s sched <scheduler name> scheduling = 1"
• The following attributes will be set on the main default scheduler if the the user sets them on the server
  • scheduling
  • scheduling_iteration
• Max length of scheduler name is 15
• By default PBS server will configure a default scheduler which will run out of the box.
  
  • • The name of this default scheduler will be "default"
    • The sched_priv directory of this default scheduler will be set to the $PBS_HOME/sched_priv
    • Default scheduler will log in $PBS_HOME/sched_logs directory.
    • Default scheduler will be provided with default set of policies as mentioned in sched_config.
    • One can set a scheduler attribute through qmgr either in the usual way as shown below or they can use the new syntax. Old syntax is supported for backward compatibility which will be deprecated soon.
      Ex:  qmgr -c "set sched job_sort_formula_threshold = <value>
             qmgr -c "set sched default job_sort_formula_threshold = <value>"
