The below diagram illustrates how WSO2 MB and two RDBMSs are set up as resource managers for a distributed transaction. In this example, a client (ESB profile of WSO2 EI) is sending an XA transaction. Each of the messages included in the XA transaction should be delivered to the relevant resource manager. However, if at least one of the resource managers fail to receive the message successfully, the XA transaction should be canceled.
