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.

Problem summary

Problem conclusion

  • First fixed in DB2 UDB Version 9.5, FixPak 1
