A couple of things to note on this. If you have scripts that explicitly
set such formatting, then maintaining them is a part of the cost of
upgrade.
The second thing, is that I see Stephan has an Oracle Cloud signature which
presumably implies 12.2. If the scripts you are referring to are login.sql
then there is a behaviour change in 12.2 which means they won't run. See
Franck Pachot at
https://blog.dbi-services.com/oracle-12cr2-changes-for-login-sql/ for the
details.

One thing to bear in mind when using a glogin.sql - any settings set
therein can be superseded in the individual scripts, if set there.
Lookout for a FREE video by Oracle's Chris Saxon, who discusses changes to
column name lengths etc in 12c.
The video is titled "*12 Things Developers Will Love About Oracle
Database 12c Release 2". *

Hey Sandra,
A lot of columns got bumped up significantly in size in 12c. desc
dba_objects in a 12c and 11g database to see. Owner, subobject_name, and
edition_name have all been bumped from 30 to 128.
I’m almost certain that’s what you’re running into. I don’t know an easy
workaround other than, as you described, formatting the columns.
We’ve been playing with changing them in glogin.sql that we can then push
out to all our servers, rather than updating each and every script.
Hope that helps,

*Subject:* SQL result formatting on TO_CHAR different in 12c
Oracle EE 12.1.0.2, 2-node RAC
RHEL 5
We recently upgraded from 11.2.0.4 to 12.1.0.2. We have several scripts
running out of crontab to monitor various aspects of our applications. The
analysts are seeing different formatting of the results of these scripts in
12c than they did in 11g.
11g - all output was on one line - linesize set to 1000, only 10 columns,
date, timestamp, and number formats. In the script, they use TO_CHAR to
get the desired format.
12c - no changes to the script; now each column is on a separate line. If
I set linesize to 10000, I see the expect behavior with a whole lot of
whitespace between columns.
I still had copy of this production database that I used to practice the
upgrade. I went in and changed the parameter permit_92_wrap_format to
false. Behavior reverted back to what we saw in 11g. However, I'm not
convinced this is the right workaround.
Has anyone else see this behavior? We have a lot of scripts and changing
all of them to use a column alias and column formatting (which should have
been done in the first place) would be a major undertaking. I haven't
found any bugs on MOS related to this yet or any useful information in the
Oracle docs. My co-worker is opening an SR, but no response yet.
Thank you in advance for any guidance.
