Configure the definition of your ODBC databases to the transaction manager (the queue manager).
Before you start:
You must create and configure the databases by following the instructions in Working with databases.
You, or your message flow developer, must also ensure that the message flows deployed to the broker are set up to support coordination. The tasks that are involved in configuring the message flows correctly are described in Configuring transactionality for message flows.
When you have completed these steps, your message flows are processed by using global coordination, which is managed by the queue manager.
You must complete all the steps correctly; if you do not, global coordination will not work.
