Hi Sandra,
I don't have anything with such large lines, so I cannot test, but I have recently switched to sqlcl, which I find superior to SQL*Plus in many aspects. Also, what used to be SQLPATH in releases before 12c is now called ORACLE_PATH. A little bit of additional marketing doesn't hurt, I suppose. This is what I use for my initialization script:

if [ -t 0 ]; then












cd $HOME

stty erase '^?' intr '^C' susp '^Z' quit '^Y' kill '^X' echoe



tset -r

[ -r $HOME/.aliases ] && source $HOME/.aliases

The beginning if -t 0 is a remnant from an old version of Red Hat which used to be confused by LD_LIBRARY _PATH set to $ORACLE_HOME/lib and some GUI tools did not work. As fas as I remember, there was an incompatible Python library in $ORACLE_HOME/lib, which used to mess up Red Hat GUI.

We recently upgraded from to 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.
