I really liked the idea of keeping the backups mirro
Why do you think this?
"The failure I see of this system is that even though the db is
paused, it
is not in a "safe" state for backup."
Once you broke the mirror would it not be safe to backup that array??
The db is basically in "mid sentence". The commits are not atomic.
If you restore
One quick point is that this is one of the differences between Pick
heritage & Prime heritage.
See "Guide for Pick Users" in the UV doc set. If you were a Pickie, it
helps UV make sense in a hurry. UV republished that guide after a long
lapse, thanks to U2UG's pressure, iirc.

This I-descriptor or EVAL should help you:
LIST VOC _
WITH EVAL "CONVERT( @AM:@VM:@SM:@TM, 'avst', @id )" # @ID _
ID.SUP EVAL "CONVERT( @AM:@VM:@SM:@TM, 'avst', @id )"
(To be rigorous, char(247 thru 250) are also treated as system
delimiters. You might test for them, too.)

2. Use resize if you can get exclusive use of the file. (I don't
think "CONCURRENT" works with dynamic files. but I'm wary with
static too.)
RESIZE will allow you to set the minimum modulus, but maybe not using
the syntax as documented. And syntax differs according to acct
flavour and OS (and

While CREATE.FILE . . . MINIMUM.MODULUS does indeed reserver room in the

I've seen records at least an order of magnitude larger than that. Unix

verify that and when numbers get that big, my brain can't get around
them. ( e.g., $1,000,000,000,000: www.pagetutor.com/trillion/index.html )

Back in 2002, when I wrote that, I couldn't set it to 0 and disable it.
Didn't know 0 now works. Good. I usually peruse the release notes and
don't recall that change. I agree, setting it to 0 to turn it off makes
sense.

What happens if a UV process shells out & executes a shell script that, in
turn, invokes uv?
I don't think it increments the user count, but I'm not sure. I do know it
stomps all over the parent uv's "printer segment", so it's generally not a
good idea.
And, yes, look up uvlictool. there are "re
In a prior release 10.0 or earlier, I encountered a problem that could
corrupt an index if a write was issued without an explicit readu preceding
it. I don't think IBM ever corrected that because writing without
explicitly locking is Bad Form.
If I remember, when process A holds a lock on a record
Yes, WHEN can be frustrating.
1st, make sure the multi-valued associated fields are properly defned with
M's in field 6, association name in field 7 and, for good measure, create a
phrase with said association name as the id of the phrase, and all the
associated fields listed in <2>.
