>Sharing DASD was around long before sysplex... There are two falacies regarding technology: 1. This is old, therefore good. 2. This is new, therefore better.
Shared DASD has been around for a long time, but I will only share within SYSPLEX boundaries. Sharing outside a SYSPLEX (or a Single System SYSPLEX) requires, either: 1. RESERVE/RELEASE processing -- risky. 2. GRS Ring -- response degrades exponentially as you add systems. 3. CA-MIM -- added cost. - Too busy driving to stop for gas! ---------------------------------------------------------------------- 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
