This kind of "WOW"! has been around for a lonnnnngggg time!

Remember IMS/XRF (not needed with SYSPLEX)?

The first time we had an auto XRF switch (not operator initiated; due to a 
failure), nobody but operations/SYSPROG knew.

Nor, did they when we restarted the primary and switched back.

IBM auto fail-over has been around for years.

(Actually, I remember TANDEM doing in in 1981).


When in doubt.
PANIC!!
