Connecting Apex with MySQL on OCI: A Step-by-Step Guide

Are you struggling to connect your Apex application with a MySQL database on Oracle Cloud Infrastructure (OCI)? Worry no more! In this comprehensive guide, we’ll walk you through the process of setting up a seamless connection between Apex and MySQL on OCI.

Prerequisites

Before we dive into the connection process, ensure you have the following requirements met:

• A running Apex instance on OCI
• A MySQL database instance on OCI
• A basic understanding of Apex and MySQL
• A text editor or IDE of your choice
• An Oracle Cloud account with the necessary credentials

Step 1: Create an OCI MySQL Database Instance

If you haven’t already, create a new MySQL database instance on OCI:

1. Log in to your Oracle Cloud account and navigate to the OCI dashboard.
2. Click on the “Navigation Menu” icon in the top-left corner and select “Databases.”
3. Click on “Create Autonomous Database” and select “MySQL” as the database type.
4. Fill in the required information, such as database name, username, and password.
5. Click “Create Autonomous Database” to create the instance.

Step 2: Create an Apex RESTful Service

In this step, we’ll create a new Apex RESTful service to interact with our MySQL database:

1. Log in to your Apex instance and navigate to the “SQL Workshop” section.
2. Click on “RESTful Services” and then click on “Create RESTful Service.”
3. Enter a name for your service, select “MySQL” as the database type, and click “Create.”
4. In the “Service Definition” section, add a new module with the following settings:
   

   Module Name	HTTP Method	URI Template
   MySQL Connection	GET	/mysqlconn

5. Click “Apply Changes” to save the module.

Step 3: Configure the Apex RESTful Service

In this step, we’ll configure our Apex RESTful service to connect to our MySQL database:

DECLARE
  l_url                       VARCHAR2(255) := 'https://your-mysql-db-instance-oci.oraclecloud.com:1522';
  l_username                   VARCHAR2(255) := 'your-mysql-db-username';
  l_password                   VARCHAR2(255) := 'your-mysql-db-password';
  l_service_name              VARCHAR2(255) := 'MySQL Connection';
  
BEGIN
  APEX_SERVICE.GENERATE_SERVICE_DEFINITION(
    p_service_name => l_service_name,
    p_base_url => l_url,
    p_username => l_username,
    p_password => l_password
  );
END;

Replace the placeholders with your actual MySQL database instance details.

Step 4: Test the Connection

In this final step, we’ll test the connection between our Apex application and the MySQL database:

1. Run the following SQL query in your Apex instance:
   SELECT * FROM MySQL_Connection;
2. If the connection is successful, you should see a result set with data from your MySQL database.
3. Test the connection using a tool like Postman or cURL by sending a GET request to https://your-apex-instance-oci.oraclecloud.com/rest/(your-service-name)/mysqlconn

Troubleshooting Common Issues

If you encounter any issues during the connection process, refer to the following troubleshooting tips:

• Ensure that your MySQL database instance is running and accessible.
• Check the Apex service logs for any error messages.
• Verify that the database credentials are correct and that the username and password are correctly formatted.
• Check the OCI network security settings to ensure that the Apex instance can access the MySQL database instance.

Conclusion

In this article, we’ve walked you through the process of connecting your Apex application with a MySQL database on OCI. By following these steps, you should now have a seamless connection between your Apex instance and your MySQL database instance.
