Error description

  • The total CPU usage as reported by db2pd and the
    ENV_GET_SYS_RESOURCES procedure is not of the correct scale on
    Linux, Sun and HP platforms. The CPU usage on these platforms
    is on a scale of 0 to 1 instead of 0 to 100. The Idle time is
    also wrongly reported as Wait instead of the correct Idle.
    Before fix :
    CPU Usage Information:
    Total   Usr     Sys       Wait Idle
    0.022500  n/a      n/a 0.977500    n/a
    After fix :
    CPU Usage Information:
    Total   Usr     Sys       Wait Idle
    2.250000  n/a      n/a n/a    97.750000
    

Local fix

  • The temporary fix is to multiplythe value reported by db2pd by 1
    00 and consider the value of "Wait" as "Idle" in this case.
