My system crashed.
Now when I bring it back up it starts to behave strangely, indicating
several system files cannot be accessed. I can sign on, as
MANAGER.SYS, but most of the accounts that used to be on the system
cannot be found. When I do a listf of PUB.SYS, most of the files have
a message associated with them that reads:
*BAD UFID FOR
THE FOLLOWING FILE : /SYS/PUB/COMMAND
05650002 1B8D7A30 000042D2 18020864 0266B8F5
Bad UFID for
the file /SYS/PUB/COMMAND (CIWARN 9165)
I believe the
system disk experienced some difficulties at some point,
and Im not sure what happened or if its repairable. Of
course I have a SYSGEN tape, but never having had to use one, I need
to know if it contains the SYS account files necessary for me to
begin reconstruction and reloading of accounts.
Paul Courry replies:
Bad UFID is a
bad Universal File IDentifier. In other words, your file system is
corrupted. You can try running FSCHECK.MPEXL.TELESUP (run with
EXTREME care, reading the manual first) but considering the extent of
the damage you probably will not be able to recover everything.
Larry Barnes notes:
tape may or may not have the SYS account on it. It depends on how the
tape was created. You can generate a SYSGEN tape and have it include
certain accounts. I usually included sys and TELESUP on the tape.
have missing accounts as well as the UFID problem, it seems your
system directory is damaged. I think its a safe bet that your
system volume set is clobbered. You need to do an INSTALL from your
SLT. This will re-install your operating system and give you a brand
Files, groups, and
accounts on private volume sets are still there, but you will need to
recreate the system directory entries for those accounts and groups.
If you have BULDACCT output, that will make the job easier. Its
always a good idea to run BULDACCT periodically and store the result
to tape for just this eventuality. [Editors note: I use
BULDACCT as backup in case my primary method to recover directory
entries fails for some reason: the DIRECTORY option of STORE.]
You will also need to
restore the contents of your system volume set. Make sure you use the
KEEP option so you wont lose any files created by the INSTALL.
You might want to purge or rename COMMAND.PUB.SYS before the restore,
so you get your SETCATALOG definitions restored along with the
What are the PIN
configurations to go from a DTC RJ45 distribution panel to a
Mark Halstead replies:
this recently. What I got from HP was that the RJ45 ports
dont generate modem signals. If you have a DTC16 or
DTC72 you can get a MDP Modem Distribution Panel to provide
I have an older HP
3000. I want to add a standalone single ended HP DLT drive. What HP
DLT4000 external drives are supported on MPE/iX?
A DLT4000 is
a DLT4000. Any one will work. HP no longer sells DLT4000 devices.
They only sell DLT8000 and probably SDLT, but the latter is not
currently supported on MPE. You should be able to find a used DLT4000
most anywhere for a very low price. It will be easy to attach
directly to a SCSI port on the system, just make sure it is not a
differential (FWD) SCSI port. In SYSGEN, the device ID will be
DLT4000. Use the shortest cable you can get away with.
We experienced a
power outage Sunday. After bringing everything up I have a couple of
serial connected printers (Zebra) that do not want to work properly.
How can I get them online?
Jeff Kell replies:
to see if the DTCs are healthy. If they power failed as well, they
may not have been downloaded correctly (by the host or by DTC
Manager, whichever flavor you use for configuration).
We have been
successfully using and recommending DDX for years. We tried MDX way
back when it was first introduced and got corrupt databases. We have
a real need for it now, however. Is MDX as stable as DDX now? Our
3000s run MPE/iX 6.5. Is this adequate? Are special patches
Guy Paul replies:
you refer to about corruption was a serious one from the 5.5 days. It
has been patched and no serious ones like it have popped up that I am
aware of. There are some corner cases when corruption can occur but
the latest TI patch TIXMX73 should fix them. Without MX73 the
possibility exists that if more than one dataset expansion (DDX or
MDX) happens within one dbxbegin/dbxend and then rollback (dbxundo)
the transaction you will get corruption. Fortunately the corruption
is in the user label and not in the data. The scenario for this would
be very complex transactions and very small increments on your
expansions so it was a corner case. So, to answer your question - MDX
is stable, as is DDX.
What should be
done to move a Series 959 about 15 feet across the office? Is it
possible to just power it down (removing all connections of course)
and roll it across? Or do we need to get HP involved with it?
John Burke replies:
there, done that. However, my understanding of HPs official
policy is that if the system does not come back up okay, the repair
is not covered under your support contract since you moved it.
John Clogg adds:
case, you roll it back to its original location before you call HP.
But seriously, rolling machines around in the room is no big deal,
and people do it all the time. I would definitely involve HP if
moving the machine to a different site, but not for the move you
While waiting for
a backup to finish, I began to ponder anew about a recommendation
from HP. Ever since STM was foisted upon us, and HP Predictive
Support was changed since it needs STM, HP has recommended that the
JPSMON job should run all of the time. I have wondered why JPSMON
couldnt be started, say 10 minutes before Predictive was
scheduled to run, and then aborted sometime later when we are sure
that Predictive ran successfully. Any thoughts on this topic?
HPs ITRC replies:
suggestion is good food for thought this morning. I see no reason why
your plan would not work. I believe the reason we recommend JPSMON be
ran at all times is to guarantee it is running when Predictive runs.
Besides, the job takes little if any resources.
Im doing a
report in Query. I can get line breaks after a total, but want a page
break. How can I do this?
Mark Wonsil and
Roy Brown reply:
breaks will be SPACE A [number] or SPACE B [number] I imagine. Use
SKIP A or SKIP B (no numbers) in place of these, to page break. See
docs.hp.com/mpeix/all/index.html#QUERY/iX for the appropriate
