We've been running NTP for every with no ill effects. Our authentication product requires it be there (to active directory so presumably Kerberos is the reason).
Now.. Funny this topic should come up. I was about to ask about this which came out the SLES 10 SP2 Release notes: http://www.novell.com/documentation/sles10/pdfdoc/release-notes_sp2/rele ase-notes_sp2.pdf * zSeries: ETR (external time reference) Support: Enables Linux images to synchronize with parallel Sysplex or GDPS by providing z/OS compatible external timer reference and maintaining data consistency groups for XRC data mover. More info: The ETR support introduces a new kernel parameter "etr" that is used to set the initial state for the online attribute of the two ports. The syntax of the parameter is "etr=[on | off | port0 | port1]". The default is "off". The ETR support introduces a number of sysfs attributes. There are two time synchronization ports etr0 and etr1, which can be accessed via sysfs under: /sys/devices/system/etr Is this for under z/VM as well ? (we are going to be doing XRC r.s.n.).
