Given the stability of the z System clock, good practice is to run 'ntpdate' shortly after Linux boots and then perhaps at (long) intervals. Performance opinions vary. I found that 'ntpd' is one of the better behaved daemons in terms of load. Originally I told customers "kill it". But I no longer insist on this. (Always a good idea to minimize the number of tasks running on a guest.) My teammate Rob van der Heij may have additional details to share. Alan Altmark explained some of the STP behavior over on the IBMVM list just last week. Perhaps he can chime in on this too. -- Rick Troth Senior Software Developer Velocity Software Inc.
