Lars Appel replies:
You can try
the TELL and TELLOP commands. For more information see :HELP TELL or
When I run
dbutil.pub.sys, and type the command set MYDB btreemode1=on I get the
message Database root file must be at least C4 for
SET <db> BTREEMODE1=O." Why cant I set my
Rene Woc replies:
can set btreemode1, the database has to have Btrees. You
add Btrees with addindex MYDB for all (or specific master
datasets). This command will also set root level to C4. To use
addindex your system needs to be at least on TurboIMAGE
How do I find out
what version of IMAGE we have?
Use the Version
command of QUERY.
I need to take
some groups off of the mirrored drives, and add (move) other groups
onto the mirrored drives. Is it as simple to use the altgroup command
and specify the volume set?
[Editors note: mirrored drives is a straw
man that has nothing to do with the problem or answer.]
Craig Lalley and
John Clogg reply:
It is simple
but not that simple. What you need to do is create a temporary group
on the target volume set. Copy files in the group you want to move to
the temporary group. Delete the source group. Create the new group
Note that it is a
two-step command. Then rename the files from the temp group to the
newgroup. John Clogg also noted that another approach would be to
STORE the files, and restore them once the group was relocated. That
way you could preserve creation and modification dates, and creator
On one of my
clients machines which is running MPE/iX 6.5 PowerPatch 2,
LISTJOBQ shows that a queue called EDI has a limit of 2, executing
jobs 1, total jobs 0 (not a typo):
shows no jobs executing in the EDI queue. How can I correct this?
It can be
corrected by a reboot. However, a more permanent fix can be found in
patch MPELXC2B or its successors.
I have inherited a
HP 3000, and I was trying to clean off an old TurboIMAGE database. I
did a purge @.data and it purged about 100+ files. However, it did
not purge everything. They cant be purged, even when logged in
as manager.sys. The error that I get is CIERR 45, Privileged File
access. I have tried to release it with no luck either. Any
Steve Macsisak and
Denys Beauchemin reply:
You can purge
TurboIMAGE databases using the utility DBUTIL.PUB.SYS and the command
PURGE (database name). The database name is the name of the root
file, the one without numbers at the end. The command will purge all
the datasets of the database. There are a few other ways to do this,
but this is the most
I just had a
chance to CONTIGVOL on our development system (MPE/iX 6.5):
Volutil has processed the labels on the four drives, it states:
Contigvol - Inverse Extent Tbl Full, Internal resource limit.
However, it appears to continue and finish normally. What
does this mean?
Goetz Neumann replies:
It is a
warning that an internal table has filled up. It appears it only
handles looking at 40,000 extents at a time. There was an enhancement
request (back in 1997) to increase the internal tables, which HP
decided not to work on. You can run CONTIGVOL multiple times if the
first run does not condense the free space enough because of this
I moved our HP
3000 9x7 from one room to another to do some configuration changes.
After setting everything up exactly the same, I attempted to boot the
machine. After waiting several minutes I got the Boot from
primary boot path (Y or N) question and answered yes. The
machine then asked Interact with IPL (Y or N) and I
answered yes. Then after 20 seconds I got this on the console:
status = 0
status = -4
(then a hex dump)
checked all of the connections, reseated the boards, twice and still
get this response. What does this error mean?

November 2002 issue of the 3000 NewsWire, Gavin Scott and Rich Trapp
replied to the same question: Do you have a SCSI terminator in place?
[Editors note: this was in fact the problem, a missing SCSI

or a disk drive (LDEV1 most probably) is not spinning up.
I have two device
numbers I dont want to be in use and assigned to users on the
network. LDEVs 5 and 6 are available for use and we dont want
them to be. Is there some place to configure these out of use?
Gilles Schipper replies:
these devices as network printer devices (id=hptcpjd path=none) in
sysgen. This will prevent them from being used by any logon
