APAR status

  • Closed as program error.

Error description

  • High CPU utilization in KGE component during startup on
    unix/linux/AIX. This is due to the use of the getpwnam function.
    This can be experienced in both TEMS and TEMA.
    

Local fix

  • Use the mkpasswd -f command anytime a password file is copied.
    

Problem summary

  • The monitoring server or agent can consume large amounts of CPU
    in KGE component during startup. The KGE component uses the
    getpwnam() function provided by the operating system to acquire
    a list of all root users during startup.  The function is
    inefficient and uses a large amount of CPU to accomplish its
    function.
    

Problem conclusion

  • Code in the KGE component has been changed to use an alternate
    method to acquire the list of root users.
    
    The fix for this APAR is contained in the following maintenance
    packages:
    
      | fix pack | 6.3.0-TIV-ITM-FP0006
    

Temporary fix

  • Use the "mkpasswd -f" command anytime a password file is copied.
