External Time Source - 9037 RISC UNIX
Hello List, I am looking to connect the z900 to an external time source. I will re-activate the 9037-2 Sysplex Timers, (once used when we had multiple processors), to use modem dialup to ACTS in Boulder, CO. The UNIX Group is getting Time off the Internet using NTP. They indicate I can connect to their RISC/UNIX Server to get the time, instead of dialing out. I have read, and re-read every item I could find in the Archives, but could not positively assert it is possible to connect the 9037-2 to the RISC box. Ken Clapp's CBT and Website option to make the Mainframe the primary time source looks interesting, but for the short-time, synchronizing to Boulder or the RISC is the target. Has anybody on the List connected to RISC/UNIX for their ETS ? Any insight on doing this ??

Not I, but I understand the recommended technique is to connect the EIA-232 port on the ETR to the RISC/UNIX system, perhaps by a null modem cable, and let RISC/UNIX spoof the behavior of ACTS, including the responses to dialing commands, etc. -- Cut-Paste from 9037 Planning Manual on available External Time Source options. _ __ _ | 9037 | EIA-232 | |External | Telephone Line | Console | Port |_| Modem |___¨to ACTS |_|__| |_| becomes: _ __ _ | 9037 | EIA-232 | | Null | RISC/UNIX | Console | Port |_| Modem |___¨ emulating ACTS |_|__| |_| -- gil -- StorageTek INFORMATION made POWERFUL -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: External Time Source - 9037 RISC UNIX
Gabe, I read Paul's suggestion. Unless you can find the code to emulate the Boulder time signal that sounds like a lot of work. You don't say what version of z/OS you're running. We used Ken Clapp's NTP server but on z/OS 1.6 there is a SNTP component of TCPIP. I'd recommend you dial out from the z box with the sysplex timer and then point everything else to the NTP server on the z Box. That's what we do here. Unix/Wintel world were reluctant to do that initially but eventually saw the light. Much simpler solution - and it works. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: External Time Source - 9037 RISC UNIX
The recommended solution works anywhere from 1.4 (where SNTP was introduced) on up. Below 1.4, Ken Clapp is your man. . . .

We are on zOS1.4, with zOS1.6 coming later this year.
