<snip> Can you set up a sysplex so that both machines have everything running on each CPU in the plex, and when one system crashes the other will automatically take over everything? Say you have SYSA and SYSB </snip>

A CF (at least 1) is required, preferably external to the box. ---------------------------------------------------------------------- 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
