Kill Rollback

Ok, I've got a rollback that's been running for 36 hours or so
(non-production machine luckily) after a QZDASOINIT job was ended
*IMMED...

Apparently IBM as added a 20=Kill Rollback to the WRKCMTDFN, according
to this article...
http://systeminetwork.com/article/journal-insights-getting-out-big-hammer

But it must have been added in 6.1 or 7.1 as my v5r4 system doesn't show it...

The above article has a blurb..
"It was at that point when it dawned on us, as Journal developers,
that folks shouldn’t have to make a phone call to the lab in order to
accomplish this outcome. Instead, there ought to be a tool in their
tool belt which they could use to kill the long running roll-back
phase of a commit transaction. That’s why we introduced the Kill
Rollback option on the Work Commit Definition (WRKCMTDFN) screen. "

So before I start jumping through the hoops required to make that
early morning call myself...does anybody know how kill the rollback at
v5r4?


Thanks!
