Years ago I was able to save many an IPL when QMF users would run these huge outer joins of two databases. If I could hit the right TCB, I would cancel the task and 90% of the time it would save an IPL (which was my next option).

It used to be a physical button on a real console's keyboard. Since consoles are mostly plain PCs with 3270 emulators nowadays, that key is no longer available from the console. Its an HMC action. Yes, once the restart interrupt is generated, you'll see a bunch of messages at the master console (or is it the system console). Similar appearance to the messages you see after "V XCF,...,OFFLINE" when the system is in the wait state. The restart messages tell you a bit about the job/task running on the interrupted processor and then give you the choice of (relying on my failing memory here): - ABEND the interrupted task - Giving control back to the interrupted task (is it RETRY?) - Having the system scan and repair, if neccessary, its vital control blocks, then continue. It doesn't use nor depend on CONSOLE communication. The restart interrupt handler communicates directly with the operator via disabled console communication. You need to alway reply with R 00, It's always worth a try before you decide to IPL a "dead" system. Could save you an IPL and doesn't waste a lot of time if it doesn't help. -- Peter Hunkeler Credit Suisse ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- 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
