Rick,
I believe the order of the datafiles in the BACKUP CONTROLFILE TO
TRACE comes from the file# in V$DBFILE. If you select from v$dbfile
there is no guarantee the list will be in order of the file# and the
file# is not the order in which the datafiles were created.

Order of files in alter system backup... does not matter. Wow using
Perl
to do this when then procedure is documented a 1000 times over. I am
sure
you have some very good reason. Automating something that I would
think is
not very frequent may be overkill. Oh well enjoy.

Please respond
to ORACLE-L
I'm writing a Perl script to automate the procedure to create a copy of
an
8.1.7 production DB to a development server. Both production and dev
are
HP/UX 11.0.
In doing this, I've created a file that cross-references where the
production datafiles are and where they are to be placed in dev. This
works
fine, but I also wanted to dynamically create the CREATE CONTROLFILE
statement for the "new" dev DB.
I've noticed that the DATAFILE clause does not have the SYSTEM
tablespace's
datafile first, nor are any of the other datafiles in the same order
that
they are in production (e.g. from the output of an ALTER SYSTEM BACKUP
CONTROLFILE TO TRACE). Does this matter? Does the order need to be
preserved?
I suppose I'll end up dynamically creating the cross-reference file,
which
would preserve the order, but now I'm curious.
TIA!
