Re: Defined minidisks RHEL 6.0 on z/VM to grow / FS, forgot to Persistently Setting DASDs Online with /etc/zipl.conf and zipl.

[Michael Harding]

A little more complicated...
I think you want 'VINPUT VMSG'
Then, if your guest has a directory console statement so it has other than
SYSC, you get: "HCPPCX6531E The operating system will not accept commands
from the service processor." Of course in that case a simple send works but
you still need to wrap it in an exec to get mixed case.

Re: Back to the future?

[Michael Harding]

In the guests' VMDBKs, in the SIEBK is stored the offset from the hardware
clock that gets loaded when the guest is run.  I don't recall the offset in
the block.  Unless that's different they should both be seeing the same CPU
clock.

Re: zVM/Linux Upgrade

[Michael Harding]

I wouldn't worry about it.  If you indeed mean MAINT and not MAINT6xx,
there's nothing there but a basic PROFILE EXEC, PROFILE XEDIT and SYN
SYNONYM.  If you'd accumulated other files there you're SOL where they're
concerned, but the shipped files are easily recreatable (or copy from one
of the other maintenance ids).

 The protection is in place because of the allocation map.  Unlike other
 files on the disk, it is in a fixed location since it is written during
 FORMAT and its size never changes, as that size is based on the size of
 the disk.  But if you add more cylinders, you add more blocks.  And as
you
 do that, the allocation map has to grow.  But it can't grow.  It's
 surrounded by other data.

 I have to say, it's kind of fun to lean back in my rocking chair and see
 my programmer id in FORMAT (DMSFOR) from back in the mid-80s.  :-)

I have to take exception.
The allocation map like the directory is at heart just another file.
Changed block(s) in the allocation map get re-written in a different
location as part of the safe updating of a minidisk's metadata.  It's size,
too, is at least partly malleable.  Pulling from another of your posts,
allocate and format a 200-cylinder minidisk.  That's big enough for the
allocation map to be larger than one disk block.  It will actually occupy
3: two data and one index block to which the directory points.  Now recomp
the disk to 150 cylinders.  The allocation map will now fit in a single
block and that's all that gets written.  If you later recomp back to 200
cylinders (as you pointed out, that's do-able) the allocation map will grow
back to its original size and its directory entry updated accordingly.

 Greetings,
 I am hoping someone out there has seen the problem below and has a
 solution.
 (PS. I am NOT the system administrator, just a user.)
 We are running RHEL 2.6.18-92.e15 Server 5.2 on zVM 6.3.0 service lvl
 1302.

 My students and I are all experiencing this problem:
 1. Set up a VPN tunnel to our VM site (if we are off-campus)
 2. Connect via MTN3270 from Windows 7
 3. Boot Linux (no mods)
 4. #cp disc (with SET RUN ON)
 5. Cannot connect to Linux via SSH, Putty, VNC-clients (the VPN
tunnel
 is still open)
 BUT, if we leave the 3270 session open (not logged in to Linux), we can
 connect and all is OK. Also, if we re-open the 3270 window after we
 disconnect and leave it open, we can then connect.

 We have been using Linux on zVM for several years w/o this problem. Does
 anyone have any tips on what to look for?

Re: RACFSMF issues

[Michael Harding]

Assuming you're running the supplied SMFPROF, take a look at the smffreq
variable setting.  This may not be the day for it actually to do anything.
Also, if you read the code, it's looking for a list of servers to be
stacked and failing that looks in its reader for files coming from your
racf server(s), that are sent when an smf disk files, to determine the
server's (or servers') id(s).

Re: RACFSMF issues

[Michael Harding]

In this case start it with #CP XAUTOLOG RACFSMF#RACFVM.  This assumes
you've renamed SMFPROF to PROFILE, or that your profile exec runs SMFPROF
without touching the stack.

 The VM FTP client requires CRLF (0x0d0a) sequences on the wire for text
 transfers.  This is not configurable, as it is a required element of the
 FTP protocol.

 Unix-based ftp servers and clients that transmit just LF instead of CRLF
 are effectively sending the file in binary rather than in the ftp
 canonical text format.  If the Linux ftp daemon is not configurable to
 operate per the standard, I'd open up a ticket with my service provider.

Re: Speed of BASH script vs. Python vs. Perl vs. compiled

Based on John's previous posts and the dataset names referenced in this,
I'd say he's playing with the output from z/OS' RACF database unload.  If
his zlinux is VM-hosted, I'd be inclined to bring the files to VM first,
mung them up with CMS pipelines then transfer the output files to his
guest.  Or even write them to CMS minidisks and pick them up using cmsfs.

I think there's also the factor that most are well into their 30's before

important in the long run than flash and sizzle.
Ron Wells' post makes a good point, but the fact is that as it settles into

Re: HCPGIR450W and HCPGIR453W after editing user direct

[Michael Harding]

Think of it this way:
The directory definition of a guest are the specs used to construct its
virtual machine when it logs on.
Re-iplling a guest without logging off/on is the same as rebooting your
windows box without making physical changes to it, changes to the specs
aren't seen.
(There are commands which can change the virtual machine configuration
dynamically, an IPL without logoff/on will pick them up and may not even be
necessary, depending on what they are and the guest's OS; but that's
independent of directory changes.)
