SV: Synchronizing TOD between mainframe and other platforms
There's one very good reason to get file 501: it comes with ets1, a pc program that will connect with your 9037 via RS232, and act as an ETS. This will let you syncronize your mainframe time with anything the pc can be synced with.

If your IT czar is a partisan of non-mainframe systems, and those systems are now synched to a high-stratum NTP server, you must prove that the mainframe with SNTP is a more accurate reference, else why should they switch? And the README in CBT 501 says: 4) Verify your sysplex timer: - it must be set to UCT (GMT) time with your local offset - be sure it has the correct time and syncs to a good time source regularly. There's no point to having the wrong time. - warning! in case you don't know, NEVER set the 9037, always adjust it. Max adjustment is +/- 5.00 seconds per day. 5) Start the server (S SNTP) - be sure both TCPIP and SNTP have a high enough dispatching priority to provide a consistent response There are obvious hazards here. And the argument that the mainframe must be the reference is self-defeating: If the mainframe won't sync to anything else, what keeps it accurate? -- gil -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: Synchronizing TOD between mainframe and other platforms
It is not possible to have the Sysplex Timer (9037) attach to non-S/390 or zSeries servers. However, there is a way that customers can get the same time across both zSeries and non-zSeries servers in their data center. The 9037 can attach to an External Time Source (ETS), the options are described in the 9037 Model 2 planning manual as well as the Redbook SG24-2070. The 9037 attachment to an ETS supports 3 possible RS-232 protocols. To get the same time across zSeries and non-zSeries, a potential solution is: The customer uses an NTP server that also has the RS-232 protocols supported by the 9037. These NTP servers are available from multiple vendors - one example is the Symmetricom SyncServ S250. http://www.symmetricom.com/products/ntp-servers/ntp-network-appliances/SyncServer-S250/ Input options for these devices includes GPS, IRIG-B and the USA NIST ACTS telephone service. Outputs for this device includes an Ethernet NTP (Network Time Protocol) Time Server as well as the necessary EIA-232 serial time code for the 9037, the former could connect to their non-S390 or non-zSeries servers and the latter to the 9037. This would allow a customer to have the same external time source for both a S/390 or zSeries server and a non-System z server. Note that this does not provide the kind of synchronization that is required in a zSeries or S/390 Parallel Sysplex. However, it will allow the customer to have the enterprise running on the same time standard and therefore coordinate time stamps, etc. The above product is not necessarily the only one that provides this capability. Other Symmetricom models also provide this function, and if you want a second source for your External Time Source that provides similar function please do your own research to find another vendor. Other vendors I am aware of that provide this capability are Meinberg, Spectracom.

Synchronizing TOD between mainframe and other platforms
We currently have 2 z900 that is running in a Sysplex. We do have 2 9037-002 connected. We need to synchronise the TOD of our Z900 with the other platforms. All the other platforms currently obtain their time from a SUN Server that receives it's time from a ETS on the WWW. We are investigating using the Z900 as the time source, but it will still have to be connected to a ETS. The other option will be to obtain the time from the SUN Server. I have been reading on the forums and through the 9037 Redbooks, but it appears to me that I can't connect my 9037 in any way to the SUN server, even using a PC as a intermediatry source. Am I correct ? Is anyone connecting their 9037 to a AIX or Sun Server to obtain the TOD? We can't exploit STP because of the limitations of our hardware. We are currently running z/OS 1.9 Any feedback will be much appreciated Regards Jaco -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Am I correct ? I believe in one of mode its modes of operation, the 9037 will dial out to a time server such as NIST. If the 9037 is connected via a null modem to the intermediary PC, the PC should be able to intercept the dial out command and simulate the responses of time server.
