6.1 About MicroTx Library for XA

To use Transaction Manager for Microservices (MicroTx) to manage the transactions of your microservices, you need to make a few changes to your existing application code to integrate the functionality provided by the MicroTx libraries.

1. Include the MicroTx client libraries in your microservice implementation.
2. Use CDI annotations or MicroTx client libraries APIs to register the required interceptors and callbacks.
3. Use CDI annotations or MicroTx client library APIs in participant microservices to obtain the connection to their XA compliant resource manager.
4. Use MicroTx client libraries API to delineate transaction boundaries indicating an XA transaction has started, and then commit or roll back the transaction.

The MicroTx library is available for Java, Node.js, ORDS, Tuxedo, and WebLogic Server apps. See Supported Languages and Frameworks.
