Question (per Mike Henderson's post on this thread):
If a file has been setup for transaction logging,
and you make a copy of a file using OS-level tools (cp, rcp, ftp, tar,
etc.),
how do you remove the TxLg info buried in the file header of the cloned
file?
Answer:
1. Use filepeek to edit
Did you try a sequence like :
cd `cat .uvhome` ; uvsh SUSPEND.FILES ON
sync
cp . .
cd `cat .uvhome` ; uvsh SUSPEND.FILES OFF
Why not ?

Thanks for responding Bruce. The last time that I did it, I was sure that
all users had logged off.

Beware of the big problem
Alternate key index subfiles are located via a pathname stored in the file
header. If you copy a file and then update it, you may be updating the
indices of the original file. See the SET.INDEX command for a solution to
this.

Good point. My routine takes care of that as well as distributed files.
Thanks for the heads up.
I did make that mistake when I first started at this company some years ago. I
had never worked with secondary indices prior to coming here. After copying
all of our production files into a test
of those things that if you do it once, you probably
won't do it a second time.

Excellent answer Manu. I will give it a look.

Just to pick nits, if you use Transaction Logging, the txlg number is in
the file header, too. Subsequent updates of the cloned file can goof
up your logs.
Is there a similar concern with data replication?
Distributed files also have pathnames buried in them.
