Error description

  • 'cleartool space -update' hangs on the Daylight Savings Time
    transition day
    
    
    ClearCase 7.1.2.x
    
    
    Solaris 10 x86
    
    
    
    Problem as Investigated:
    
    On November 7th, 2010 at 2:00 A.M., Daylight Savings Time was
    over and the system clock was automatically turned back an hour.
     Thus, what was once 2:00 A.M. was now 1:00 A.M.   As well,
    there had been a scheduled job within the ClearCase scheduler
    that prior day which was run at approximately 3:31 A.M. in the
    morning and finally completed at 3:31 P.M. on the very same day:
     The Daylight Savings Time was some twelve and one half hours
    later, the following day.
    
    On the Daylight Savings Time end and the time was adjusted:  As
    observerd, the last 4 jobs that had been successfully completed
    from the Job that finished at 3:31 P.M. the prior day reran from
    that specific job from the ClearCase scheduler.  On checking the
    scheduled jobs, the jobs indicate that they have completed
    running:  However, the process list shows that the jobs were
    running.
    
    
    Workaround:  None.
