Re: save while active v7r1 - *IBM and also SAV

Jim,

I think you are a somewhat regular attendee of COMMON. That might be a
good place to really bone up.

Some search terms are: ragged save while active.
I think that might be the title of a redbook by Larry Youngren

With little to no journalling you may catch some grief.

Stream files are very picky and snicker at save while active.

Until we did the Mimix thing and started backing up from that we were
doing a crappy save while active. No checkpoint processing. No
journalling. Didn't care if order header was in sync with order line, etc
SAVACT(*SYSDFN). The goal being: You can back up, just don't disrupt the
users from getting into the data. I argued against it but had to bide my
time until Mimix. Only took a few years...
