Typical.  You can bet they've hidden something in there where you
least expect it.  :-)

This is interesting.  Just for the sake of "how bout this" to those who
have not experienced SP R6... Maintenance of certain components relies on
the SFS -- TSAF, GCS, VTAM just to name 3 off the top of my head.
This is what prompted my original question of "is SFS on XA's CMS" -- the
use of SFS for MAINT's purposes seemed to forshadow a trend, here.
We all know that IBM is very trendy about this stuff.  ;-)

By the way, Thanks to all of you who have commented on this question.
Your remarks are invaluable.

You're kidding, aren't you???  They are really using SFS for maintenance???!!!
UGH!  We were planning to avoid it as long as we could.  We run MUSIC/SP
which gives us all we need in terms of file sharing and didn't want to have
to deal with the headaches at this point.  At the risk of sounding negative,
I have a bad feeling that could become the sequel we were all dreading,
"Son of SES".

The most serious complaint about SES is how slow it is.  As a result,
people hate to have to restart long SES sessions.  Time after time I've
heard speakers say "So, if you have to restart SES because, say, a
minidisk has filled up...."  It's probably the most common culprit.

So, indirectly, the old problem of having to overallocate minidisks --
wasting a lot of space in little segments instead of pooling your
unused disk as a single common resource -- becomes important for SES.
For that reason, use of SFS for Maint's purposes could be a big step
forward.

Martha,  I believe that in CMS6 the assembler actually uses workfiles
in SFS.  Yes, I know that's hard to believe.

Wonderful. How do I re-assemble a piece of CMS after installing a fix for
a bug in SFS?  Ooops, sorry, how can I have been  so stupid and forgotten
about OCO? Anyway, what I've read recently on this list strongly suggests
that SFS really stands for 'a Sequel For SES'...

You know what? I'm *badly* glad I've moved to a SESless machine :-) :-)

Must be a nasty rumor.  I haven't looked at the code, but I can assemble
things under CMS6 with no SFS server machines logged on without any
problems.  Perhaps if you actually have a SFS directory accessed, ASSEMBLE
will make use of it for work files, but that seems like a perfectly
reasonable thing to try to do.  Except for having to use it to apply
service to GCS/VTAM/et al (and there may be ways around that), an SP6
system can be run without SFS with no ill side effects...we've been doing
it for going on 6 months now.

Martha, would I kid about a thing like this?

I haven't had much to do with the SP6 system -- I just installed it and
have not made any extensive trials of the pros & cons of SFS.  (I've got
SP5 on my "real" system over here.)

Without judging bugs factor or performance index, I am happy with the
*idea* of a SFS available; I could certainly use one over here on SP5
for certain special archives, etc.

We're XA, not SP6, but I suspect that the above is due to the fact that,
if you have an SFS directory accessed, QUERY DISK MAX will ALWAYS return
the filemode of the SFS directory, even if you've got an empty full-pack
A-disk.

Sigh.
