The broker uses ODBC to connect to databases. You must, therefore, define ODBC data source names (DSNs) for the broker database on each system that hosts a broker. You must also define ODBC DSNs for any user databases that are accessed by message flows that are deployed to the broker. At any one time there can be multiple connections using the same DSN definition.
On z/OS systems, see Data sources on z/OS for information about enabling connections to
databases.
For more information about the 32-bit and 64-bit considerations, see Broker database connections and User database connections.
When you have defined the appropriate DSNs, you must also configure the environment so that the broker can access the correct database libraries (see Setting your environment to access databases).
