Commit/rollback transactions manually with multiple datasources in Micronaut - jdbc

Question

I need to commit/rollback transactions manually with multiple datasources in micronaut-data. But when commits second transaction(db2TransactionManager.commit(db2Transaction)) it throws below exception. How can I solve this problem or is there any other way, also I tried with defining #Repository and #Transactional etc., but there is other problem that commits transactions separately?
