Spring 트랜잭션에서 교착 상태가 발생했을 때 스케줄러가 멈 춥니 다.

Question

SpringHibernateTemplate과 Spring-3.0 Hibernate-3.6.5를 DAO로 사용하는 모니터링 어플리케이션을 개발했습니다. 데이터베이스 SQL Server 2008.이 응용 프로그램은 매일 장기간 트랜잭션을 실행합니다.

@Repository("areaDaoHibernate") 
public class AreaDAO implements IArea { 
     protected HibernateTemplate template = null; 

     @Autowired @Required 
     public void setSessionFactory(SessionFactory sessionFactory) { 
       template = new HibernateTemplate(sessionFactory); 
     } 

     // basic dao method 
} 

이 응용 프로그램에는 springbeans를 통해 일정이 잡혀 있습니다 (실행 가능).

@Component("dailyTask") 
@Scope("prototype") 
public class DailyTask implements Runnable { 

@Override 
     public void run() { 
       // running task 
     } 
} 

이 응용 프로그램은 풀링에 Apache DBCP를 사용합니다.

이 앱이 교착 상태에 빠질 때 문제가 발생합니다. 예약을 중지하십시오.

내 질문 :

1. 내가 교착 상태 문제를 방지하기 위해 연결 풀을 변경해야 하는가?
2. 교착 상태가 발생한 후에 예약 빈이 실행되지 않는 이유는 무엇입니까?

Answer 1

SQL Server에서 교착 상태가 발생했습니다. 이것은 Spring, Hibernate, 연결 풀 또는 SQL Server 오류가 아닙니다. 문제는 응용 프로그램 또는 다른 응용 프로그램도 잠글려고하는 행을 잠그는 것입니다 (deadlock 방식).

가장 쉬운 해결 방법은 작업에 대한 재 시도 전략을 사용하는 것입니다 (실패 할 경우 전체 트랜잭션을 다시 시도하는 것). 또한 교착 상태에 관련되어있는 응용 프로그램/사용자를 SQL Server 로그를 통해 정확히 파악할 수도 있습니다.
