I have a spring boot application with postgresql and rabbitmq. I wanted to use a best-effort JTA transaction that contains both a postgres and rabbitmq transaction. I have added the spring-boot-started-jta-atomikos dependency. When I start my application I receive this warning multiple times:

atomikos connection proxy for Pooled connection wrapping physical connection org.postgresql.jdbc.PgConnection@99c4993: WARNING: transaction manager not running?

Do I need any additional configuration?

I also get this warning at startup:

AtomikosDataSoureBean 'dataSource': poolSize equals default - this may cause performance problems!

I run with the following settings, but setMinPoolSize is never called

spring.jta.atomikos.connectionfactory.max-pool-size: 10
spring.jta.atomikos.connectionfactory.min-pool-size: 5
