Oracle Database Multilingual Engine (MLE) Based on JavaScript module

This repository contains instructions on how to run the Oracle Database Multilingual Engine (MLE), based on the JavaScript module, with functions stored as procedures in the database.

Preparation #

Download the Docker container of the Oracle database with experimental support for the Multilingual Engine from Oracle Database MLE.

2. Load the Docker image:

docker load --input mle-docker-0.2.7.tar.gz

3. Run the container (note that you can also choose to configure non-default credentials):

docker run mle-docker-0.2.7

4. From another console window, run the docker ps command to show only running containers and find a necessary container ID.

5. Shell into the docker container:

docker exec -ti <container_id> bash -li

Wait for the database to start. It may take time for the first run. Next runs are faster.

6. To verify the database has started, run the sqlplus from a new command shell:

sqlplus scott/tiger@localhost:1521/ORCLCDB

Note: scott/tiger is the default login/password. ORCLCDB is a site identifier (SID). There can be more than one database on the same Oracle_HOME, which is why SID is required to identify them. If you have changed the default login/password, change the command respectively. If sqlplus works, the database is ready. Exit sqlplus.

7. Create a directory, initialize an empty node package, install the validator module from NPM, and install the TypeScript types for the validator module:

mkdir crazyawesome
cd crazyawesome
echo "{}" > package.json
npm install validator
npm install @types/validator

8. Deploy the validator module to the database. In the following command, validator is the module name:

dbjs deploy -u scott -p tiger -c localhost:1521/ORCLCDB validator

9. Start sqlplus again:

sqlplus scott/tiger@localhost:1521/ORCLCDB

10. Use the validator module functions as the stored procedures. Make sure to put a semicolon after the query:

select validator.isEmail('') from dual;
select validator.isEmail('oleg.selaev') from dual;
