    The audit record include remote hostname information that
    requires DNS lookup. It takes long time for the server to
    write audit records if DNS lookup takes long time.
    

Problem conclusion

  • Following security custom property is introduced by this APAR.
    When the value is set to false, the audit records will not
    include the remote hostname.  It still includes ip address of
    the remote host.
    
    Custom Property:
    com.ibm.websphere.security.audit.includeHostName
    Value: false (Default is true)
    
    To set security custom properties, from the administrative
    console. Click Security > Global security > Custom properties.
    Then click New and add a new custom property and its
    associated value.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 9.0.5.2 and 8.5.5.17.  Please refer to the
