this one helps. This error could be a hint that your application is unable to establish a database connection.
If you are not explicitly setting the hibernate.dialect property, Hibernate is trying to determine the dialect via a database connection. If connecting to the database is not possible, the DialectResolutionInfoSource parameter will be null when calling DialectFactoryImpl#determineDialect.
code :
WARN  org.hibernate.engine.jdbc.internal.JdbcServicesImpl [thread1] - HHH000342: Could not obtain connection to query metadata : An attempt by a client to checkout a Connection has timed out.

may help you . As a developer I would like to develop a Spring JPA to access Oracle 9i database to fetch records via stored procedures I want to connect to the database via application.yml but I initiate the project with the configuration file application.properties
code :
    Properties jpaProperties = new Properties();
    jpaProperties.put("hibernate.proc.param_null_passing", new Boolean(true));
    jpaProperties.put("hibernate.implicit_naming_strategy", SpringImplicitNamingStrategy.class.getName());
    jpaProperties.put("hibernate.physical_naming_strategy", SpringPhysicalNamingStrategy.class.getName());
    jpaProperties.put("hibernate.dialect", "org.hibernate.dialect.Oracle9iDialect");

I hope this helps you . You didn't initialize configuration, serviceRegistry, and sessionFactory correctly. From Hibernate 4.3.2.Final, StandardServiceRegistryBuilder is introduced. Please follow this order to initialize, e.g.
