Перемещение Dropwizard для ORACLE 11g

Question

Я работаю над приложением DROPWIZARD MIGRATION [Dropwizard 0.7.0]. Чтобы сгенерировать структуру db с помощью migration.xml, я запускаю команду db migrate для базы данных Postgres и ORACLE. Для Postgres Я успешно способен генерировать структуры БД, но при попытке для ORACLE с следующими детали получают за исключение

database: 
    # the name of your JDBC driver 
    # driverClass: org.postgresql.Driver 
    driverClass: oracle.jdbc.driver.OracleDriver 

    # the username 
    user: system 
    # user: postgres 

    # the password 
    password: Passw0rd 

    # the JDBC URL 
    # url: "jdbc:postgresql://192.168.1.130:5432/mydb" 
    url: "jdbc:oracle:thin:@192.168.1.130:1521/mydb" 

    # Hibernate dialect 
    # dialect: "org.hibernate.dialect.PostgreSQLDialect" 
    dialect: "org.hibernate.dialect.Oracle10gDialect" 

    # hibernate.connection.provider_class 
    connectionProviderClass: org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider 

для этих оракула настройки я получаю следующее исключение

Answer 1

Причину по умолчанию validationQuery использованного по DropWizard определяется как

SELECT 1;

, который не поддерживается DB2. Возможным решением является установка параметра validationQuery в настройке DropWizard. значения конфигурации рекомендуется для DB2:

validationQuery: select 1 from sysibm.sysdummy1

Вы можете найти подробный ответ с различными определениями для других двигателей DB here.
