Answer 1

Try adding

logging.level.org.springframework.web=INFO
logging.level.org.hibernate=INFO
logging.file=c:/temp/my-log/app.log

logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE

in your application.properties , this will show you some trace queries.

I had this problem before becouse the JPA is formating your query for example if you are calling Repository.count(); the query will be formated as select count(u) From table u which is in invalid format for the DB2, to overcome this i had to define my own @Query to be select count(*) From table u .
