      Hi,

      Oracle MCS provides connectors for only SOAP and REST based interfaces instead of native JDBC based connectors.

      However MCS lets you implement API using NodeJS which can be exposed through a Mobile blackened.

      Through this approach you can connect to any backend third party database like MySQL by utilizing node modules such as

      https://github.com/mysqljs/mysql

      Hope that helps.

      There is one caveat to Arun's info. MCS is usually running in an Oracle Managed environment. As a result, accessing ports other than 80 and 443 is restricted. To reach a MySQL server running on its native 3306 port, you would need to add port forwarding from port 80 to 3306. Alternatively, you could create a REST service layer that acts as an intermediary between port 80 and port 3306, essentially REST-enabling the database.

      I would bet it is possible to configure MySQL to listen to port 80, though I've never heard of it being done.

      With OMCe you absolutely can. You will need a pure javascript (i.e. no native code) library for the database you are trying to access. For MySQL you can use https://github.com/mysqljs/mysql.

      Just download and unzip your custom API scaffold from OMCe, then use npm to install and add the database library to your package.json dependencies.

      for example:

      {
        "name": "accounts",
        "version": "1.0.0",
        "description": "Accounts",
        "main": "accounts.js",
        "oracleMobile": {
          "dependencies": {
            "apis": {},
            "connectors": {}
          }
        },
        "dependencies": {
          "bluebird": "^3.5.1",
          "mysql": "^2.15.0"
        }
      }

       

      Then follow the instructions in your database library's documentation on how to make database queries from your own node.js api implementation code.

      Remember to include your node_modules directory in the zip file you deploy to OMCe. Our Custom Code Test Tools available from bit.ly/omcedownloads will help you test and deploy your custom code locally from the command line.
