2. Create two The above sample configuration uses two data sources and database instances to point to the sample databases created according to the synapse configuration defined above. . You have to manually create these in your environment for the sample to work.
- For information on creating database instances, refer to Database Instances. Refer the Sample Setup Guide to see how you can set up the derby database server.
...
- For information on creating the two sample XA data sources
...
- , refer to section Data Sources.
4. Start the ESB with the synapse configuration numbered 657 (synapse_sample_657.xml), by running the following command.
