• Interface 1: max_sequence_idserver attribute

  • Visibility: Public
  • Change Control: Stable
  • Details: Using this attribute admin can change max sequence id in server. Once sequence id reach this value server will rollback to 0 for next sequence id (i.e next job or reservation id). Default value of this attribute will be 9999999. Max value for attribute should be <= 999999999999. Min value for this attribute should be > 0.
  • Log/Error messages:
    • When non privileged user try to set max_sequence_id then following error message will be displayed by qmgr:
      • qmgr obj= svr=default: Unauthorized Request 
        qmgr: Error (15007) returned from server
    • When admin try to set invalid value for max_sequence_id then following error message will be displayed by qmgr:

      • qmgr obj= svr=default: Illegal attribute or resource value
        qmgr: Error (15014) returned from server

    • Following log message will be added to server logs when admin sets max_sequence_id:
      • Log event: PBSEVENT_ADMIN
      • Log level: LOG_NOTICE
      • Log message:svr_max_sequence_id set to val <value>
    • Following log message will be added to server logs when admin unset max_sequence_id:
      • Log event: PBSEVENT_ADMIN
      • Log level: LOG_NOTICE
      • Log message:svr_max_sequence_id reverting back to default val <value>

• Interface 2: qstat output

  • Visibility: Public
  • Change Control: Stable
  • Details: As PBS_MAXSEQNUM changed from 7 to 12 to support 1 trillion sequence id, so qstat output's header also got changed to adjust spaces between two field (see below space between "Job id" and "Name" field and also count of '-' in next line)
    • Previous output was:

      • Job id            Name             User              Time Use S Queue
        ----------------  ---------------- ----------------  -------- - -----
        1.vision          STDIN            pbsuser1          00:00:00 R workq 

• • • New output will be:

                   Job id                 Name             User              Time Use S Queue
