Installing oracle xe on centos ci environment

Question

Hi,
I have a CI environment that run automated tests on my application every time a commit is pushed to github, the tests are run on a matrix of environments to check if the application is able to run with different databases.
I currently have tests running with sqlite, mysql and postgres and would like to add oracle to the matrix.
The application is in python, (for those curious it is here: https://github.com/treeio/treeio) so on top of the oracle xe database itself I need to install the appropriate driver (cx_oracle)
The current CI I'm using is travis (https://travis-ci.org/), the tests run in a debian (or maybe ubuntu, I'm not sure) environment, they already have mysql and postgres installed
Installing oracle xe on debian proved to be a headache, I've found https://oss.oracle.com/debian/ unstable main non-free which contains only and old 32 bits version, while this wouldn't be a problem for me it generate conflicts when I tried to install cx_oracle dependencies
In any case I've found another CI (snap-ci.com) which uses centos, I've managed to install oracle-xe from the rpm and pip install cx_oracle finally works, but when I try to run anything that uses sqlplus it fails:
echo "CREATE USER treeio IDENTIFIED BY treeio;" | sqlplus -S -L sys/admin AS SYSDBA
sqlplus: command not found
it seems it was not added to the path or maybe I should have installed yet another rpm.
Ideally I would like to run the tests with oracle DB on both services (so I can test my application runs fine on debian and centos the same) but I can settle on running it on just one of them if you tell me it is not possible
by the way, does anyone runs oracle or any of its tools on debian? they seems to provide only RPMs. do everyone that works with oracle uses read hat only?
thanks

Hi,
The CI service have a interactive shell, I was able to further debug. I fixed the command not found problem and then it complained about permissions, but running with root gives me yet another exception.
currently my script is as below:
#set paths:
export ORACLE_VERSION="11.2"
export ORACLE_HOME="/usr/lib/oracle/$ORACLE_VERSION/client64"
export PATH=$PATH:"$ORACLE_HOME/bin"
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"$ORACLE_HOME/lib"
. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh
# create user
echo "CREATE USER treeio IDENTIFIED BY treeio;" | sudo sqlplus -S -L sys/admin AS SYSDBA
It gives me
Error 6 initializing SQL*Plus
SP2-0667: Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
I also noticed that I was insalling oracle xe 11.2 and client libraries 12.1, I'm not sure if that would cause problems but I'm installing libraries and clients with the same version (11.2.x)
