This page lists the compatible database versions for Rasa X and provides instructions on how to set up Rasa X to use Oracle as the database.
Rasa X is officially compatible with the following databases:
Oracle >= 11.0
By default, Rasa X comes with a PostgreSQL container that is used as the database, however this can be configured to use an on-premise database or your own cloud provided database etc. Please check out the Environment Variables for how to configure Rasa X to use a non-default PostgreSQL database.
Using Oracle as your Rasa X database instead of PostgreSQL requires some additional setup, which we’ll go over here.
In your Oracle database, create an empty database called
rasa and configure a user/password
that has access to it. You can also use a database with a different name, as long as it
is empty and you specify this in the
DB_DATABASE environment variable (read more
To use Oracle for the tracker store, please see the Rasa Open Source docs.
Next you have to extend the Rasa X image to include the necessary drivers and clients. First download
the Oracle Instant Client from here,
rename it to
oracle.rpm and store it in the directory from where you’ll be building the Docker image.
Copy the following into a file called
# if using community edition, please replace with rasa-x-ce FROM gcr.io/rasa-platform/rasa-x-ee:0.26.4 # Switch to root user to install packages USER root RUN apt-get update -qq && apt-get install -y --no-install-recommends alien libaio1 && apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* # Copy in oracle instaclient # https://www.oracle.com/database/technologies/instant-client/linux-x86-64-downloads.html COPY oracle.rpm oracle.rpm # Install the Python wrapper library for the Oracle drivers RUN pip install cx-Oracle # Install Oracle client libraries RUN alien -i oracle.rpm USER 1001
Then build the Docker image:
docker build . -t rasa/rasa-x:0.26.4-oracle
You can now use this image instead of the standard one, by replacing it in your
You will also have to configure the following environment variables for Rasa X
in order to connect to the database:
DB_USER="<user>" # username used for authentication DB_PASSWORD="<password>" # password used for authentication DB_DATABASE= "rasa" # path to your db DB_DRIVER="oracle+cx_oracle" DB_PORT="<port of db>" # Port of your SQL server DB_HOST="<host of db>" # host of your Oracle server DB_QUERY="<query>" # optional dictionary to be added as a query string to the connection URL
Alternatively, you can also directly pass the database connection URL to the container, by defining the
