MySQL

Martini Server Runtime is optimized for seamless integration with MySQL databases, offering robust JDBC connectivity. This integration enables applications to efficiently query, update, and manage MySQL data. With its scalable and efficient database connectivity, Martini ensures reliable data management and smooth operation for applications dependent on MySQL. It is ideal for scenarios requiring high-performance database interactions and strong backend support.

Configuring MySQL

This involves specifying database connection details, including host, port, user credentials, and database name in the Martini configuration files. Proper configuration ensures reliable data access, optimized performance, and seamless integration with applications. Here's a straightforward guide to adding a new database connection:

Configuration Guide

Via API Explorer: Database connections can be configured using the Martini API Explorer, a user-friendly interface designed for efficient interaction with the system's APIs. Follow these steps to configure the database connections through the API Explorer:

  1. Access the API Explorer: Open a web browser and go to [HOST]:8080/api-explorer/ to access the API Explorer.

  2. Navigate to the Database Tag: Locate and click on the database tag within the API Explorer to view various database configuration and operation endpoints.

  3. Configure Connection Pool: Use the esbapi/databases endpoint found under the database tag to save a database connection pool.

  4. Use POST to Save a Connection Pool: Save the connection pool by using the POST method at the /esbapi/databases endpoint. Here is a minimum requirement for a JSON payload:

     {
     "name": "[name]",
     "type": "jdbc",
     "url": "jdbc:mysql://[HOST]:[PORT]/[dbName]",
     "driverClassName": "com.mysql.cj.jdbc.Driver", // This is the driver for MySQL
     "username": "[username]"
     // Ensure to provide a password field if authentication requires it
 }

Via File System: Alternatively, database connections can be modified directly in the file system by editing the <name>.dbxml file located in the /<martini-home>/conf/db-pool/ directory. The <name>.dbxml file refers to the specific file for your database configuration. This method is particularly useful in environments with restricted API access or during initial setup stages.

To modify database connections directly through the file system, follow these steps:

  1. Locate the Configuration File: Navigate to the /<martini-home>/conf/db-pool/ directory on your server and locate the <name>.dbxml file.

  2. Edit the Database Connections: Open the <name>.dbxml file in a text editor and modify the database connection properties.

  3. Save and Restart: After making the desired changes, save the file. It is essential to restart the Martini Runtime instance to apply the new settings. This ensures that all components of the application use the updated JDBC configuration. Here is a minimum requirement for a dbXML:

     <driverClassName>com.mysql.cj.jdbc.Driver</driverClassName> <!-- This is the driver for MySQL -->
     <username>[username]</username>
     <!-- Ensure to provide a password field if authentication requires it -->
 </database>

Configuring MySQL in Martini Designer

  1. Navigate to the Navigator view and right-click on the Databases node of the instance where you intend to add the database connection.
  2. Choose New > Database Connection.
  3. Specify a name for the connection and select the database type JDBC.
  4. Fill in the database connection details in the provided form.
  5. Save the changes.

Database Properties

These properties include various settings that control the operation of the database. For detailed information on configuring these settings, refer to the JDBC database properties documentation.
