We only have one timer. We only use it to keep the clocks relatively close to reality and to keep them consistent across the enterprise. Also, if you lose the timer, you can recover and run without it. It takes a few seconds for error recovery and to present the option on the console. By this time, most of our communication sessions time out, so we've got some work to do to get everything reconnected. But batch JOBs continue to run and everything else runs just fine too once you restart all your VTAM applications and such. ---------------------------------------------------------------------- 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
