Batch stuck due to metadata table value deletion

问题

My Spring batch application getting stuck when multiple batches run on same time with huge data. Getting the below exception

Blocked resource    ridlock fileid=1 pageid=69265493 dbid=6 id=lock2a36e0c00 mode=X associatedObjectId=72057594039631872 
Blocked database    *****

Blocking Host (User)    ZNAPCDP1842V (myuser) 
Blocking application    jTDS 

Blocking statement  N/A 
Blocking batch/sp   delete from BATCH_STEP_EXECUTION_SEQ where ID < 145678

I am using spring boot version - 1.2.5, Hibernate 4.3.5 I am NOT using XML based configurations

I have the approach described in below link

Multiple Spring Batch jobs executing concurrently causing deadlocks in the Spring Batch metadata tables

As I am using Java based configurations, I have done it as follows


@Configuration
@EnableBatchProcessing(modular=true)
public class AppConfig extends DefaultBatchConfigurer{

    @Autowired
    DataSource datasource; 

    @Autowired
    PlatformTransactionManager transactionManager; 

    @Autowired
    public void setDataSource(DataSource datasource) { 
        this.transactionManager = new DataSourceTransactionManager(datasource);
    }


    @Override
    public JobRepository createJobRepository() throws Exception{

        setDataSource(this.datasource);

        JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
        factory.setDataSource(datasource);
        factory.setTransactionManager(transactionManager);
        factory.setIsolationLevelForCreate("ISOLATION_REPEATABLE_READ");
        factory.setTablePrefix("BATCH_");
        factory.setDatabaseType("SQLSERVER");
        factory.setMaxVarCharLength(1000);
        return factory.getObject();

    }

//Registering my job configuration beans
    }

It works till some point and fetches data from most of the hibernate queries, but throws below exception at some point "java.lang.ClassCastException: org.hibernate.action.internal.DelayedPostInsertIdentifier cannot be cast to java.lang.Long"

This time it tries to read data from the below query

@Query("SELECT tb FROM TBodyPart tb " +                             
            "WHERE tb.tPlan=?1 and LTRIM(RTRIM(tb.iBodyPart)) = LTRIM(RTRIM(?2)) and LTRIM(RTRIM(tb.iName))=LTRIM(RTRIM(?3)) and (LTRIM(RTRIM(tb.iOrientation))=LTRIM(RTRIM(?4)) OR tb.iOrientation=?4 )")
    public TBodyPart findDetailsMethod(TPlan tPlanId,String bpName,String iName,String iOrientation);

What could be going wrong here?? Why it fetches all other queries fine but throws exception with this one only??

NB: The above query works fine if I remove what I have added in the AppConfig Class to avoid batch stuck issue. (factory.setIsolationLevelForCreate("ISOLATION_REPEATABLE_READ");). I have tried other isolation levels as well

Configuration file before edit


@Configuration
@EnableBatchProcessing(modular=true)
public class AppConfig{
@Bean
    public ApplicationContextFactory myJobContext(){
        return new GenericApplicationContextFactory(MyJobConfiguration.class);
    }
}

After edit


@Autowired
    DataSource datasource; 

    @Autowired
    PlatformTransactionManager transactionManager; 

    @Autowired
    public void setDataSource(DataSource datasource) { 
        this.transactionManager = new DataSourceTransactionManager(datasource);
    }


    @Override
    public JobRepository createJobRepository() throws Exception{

        setDataSource(this.datasource);

        JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
        factory.setDataSource(datasource);
        factory.setTransactionManager(transactionManager);
        factory.setIsolationLevelForCreate("ISOLATION_REPEATABLE_READ");
        factory.setTablePrefix("BATCH_");
        factory.setDatabaseType("SQLSERVER");
        factory.setMaxVarCharLength(10000);
        return factory.getObject();

    }
}
