Oracle Database 12.2 contains a SQLcl version and a JDK 8 as well. Therefore there is no need to make other versions of these component a part of this image. Removing them will reduce dependencies and the size of the image.

I'm login at the docker image as root. I would like to access as 'oracle' user since the 'oracle; user is defined and configured on this image.

sh-4.2# cd /home
sh-4.2# ls
oracle
sh-4.2# cat oracle/.bash_profile

.bash_profile

Get the aliases and functions

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH
export JAVA_HOME=/u01/app/oracle/product/12.2.0.1/dbhome/jdk
export ORACLE_HOME=/u01/app/oracle/product/12.2.0.1/dbhome
export ORACLE_BASE=/u01/app/oracle
export PATH=/usr/sbin:$PATH:/opt/sqlcl/bin
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export TMP=/tmp
export TMPDIR=$TMP
export TERM=linux

but I receive following error:

sh-4.2# su - oracle
Last login: Tue May 2 12:25:43 UTC 2017
su: cannot open session: Permission denied

Any idea to login as oracle user ?

Best Regards, Silvio

if you add -v ***:/u01/app/oracle , then it can not run !
if not add -v *: , it has no database instance !

so it is a trash!
