Error description

  • On Linux systems that have a kernel version of 2.6 or later the
    value of hrSystemUptime is incorrect.
    

Local fix

Problem summary

  • On Linux we were getting the data for hrSystemUptime from the
    times() function. As of Linux 2.6 the starting point for this
    function changed. This was causing  out calculations to be
    incorrect.
    

Problem conclusion

  • We now obtain the value for hrSystemUptime from /proc/uptime as
    this is consistent across both 2.4 and 2.6 Linux kernels.
    
    The fix for this APAR is contained in the following maintenance
    packages:
       | fix pack | 4.0.0-TIV-SSM-FP0006
       | LA interim fix | 4.0.0-TIV-SSM-LA0005
