неразрешенный - org.hibernate.id.enhanced.SequenceStyleGenerator.generate

Question

Я использую Spring boot version 1.5.4.RELEASE

У меня есть объект, определенный как ниже

@Setter
@Getter
@ToString
@NoArgsConstructor
@Entity
@Table(name = "EVT")
public class EventData {

  @GenericGenerator(
      name = "eventSequenceGenerator",
      strategy = "org.hibernate.id.enhanced.SequenceStyleGenerator",
      parameters = {@Parameter(name = "sequence_name", value = "SEQ1_EVT")})
  @Id
  @GeneratedValue(generator = "eventSequenceGenerator")
  @Column(name = "EVT_ID")
  private BigInteger evtId;

}

Я использую DB2 в качестве базы данных. Мой конфиг источника данных из application.yml

  datasource:
    url: <my_url>
    ## Connection pool 
    tomcat:
      db-properties:
        clientProgramName: event
      initial-size: 0
      max-active: 150
      max-idle: 10
      min-idle: 0
      max-wait: 10000
      test-on-borrow: true
      test-on-return: false
      validation-query: SELECT 1 FROM SYSIBM.SYSDUMMY1
      validation-query-timeout: 300
      remove-abandoned: true
      remove-abandoned-timeout: 360
      default-transaction-isolation: 1
      min-evictable-idle-time-millis: 30000
      time-between-eviction-runs-millis: 1200000

Время от времени я получаю сообщение об ошибке ниже. В день примерно 5 раз.

• Я пропустил какую-либо конфигурацию в application.yml?
• Нужно ли мне увеличивать размер пула?

Как узнать, какой диалект установить снизу в application.yml. Моя версия DB2: DB2 v10.5.0.9

1. DB2Dialect
2. DB2390Dialect
3. DB2400Dialect
