Other than hardware
related issues (check the disk...) (I see Jerry spotted this one
:-)
The &COMO& file
is really an O/S level directory - when you run ED you are running a BASIC
program which does a READ on a record (file) in the file
(directory).
If the file is massive -
as is quite possible ...... then this will churn the system
terribly.
Check the file size at
the O/S before you use the ED command - or after if it seems to
hang...
You can play around with
increasing various limits - but the bottom line is don't do it - if your
&COMO& files are that big I would lay odds their
main use is occasional diagnostics or an audit trail (if needed)
(no-one reads a 1000 page report)....
You can use the sed
command at Unix if you need to manipulate something really big - otherwise you
could use vi (sed is less friendly - but I think it can handle bigger
files..........
If you are using a
program then take a look at OPENSEQ/READSEQ/WRITESEQ/CLOSESEQ (don't forget
CLOSESEQ ! ) rather than OPEN/READ/WRITE.
One other possibility is
a no-no character in the file - but this usually results in truncation rather
than any other symptom.

From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Robert Porter Sent: 27 January 2004 22:05 To: [EMAIL PROTECTED] Subject: Periodic COMO file problem This has happened a couple of times now. The &COMO& file
somehow becomes "corrupt" - for the lack of a better explaination. Any
attempt to edit a record in it results in a severely hung process. You won't be
able to break out of it. MASTER OFF (usernumber) doesn't work. A
standard kill at the Unix level won't touch it either. It will take a kill -9 to
get rid of the user.
This is on a UniVerse 9.5.1.1 box running under HP-UX 11.0. It's run
fine for a couple of years now, and has recently (past few months) begun strange
occurances like this. It's also periodically corrupted a few dynamic type
files as well. On those, it simple would fail with a Fault Type X (11/13
IIRC). Anyone experienced anything like this before?
TIA,
Robert
