Spring Batch ORA-08177: can't serialize access for this transaction when running single job, SERIALIZED isolation level

Question

I am getting this exception with SERIALIZED isolation level on JobRepository in Spring Batch:

org.springframework.dao.CannotSerializeTransactionException: Pr         


        

Answer 1

From official doc - 4.3.1

The default isolation level for that method is SERIALIZABLE, which is quite aggressive: READ_COMMITTED would work just as well; READ_UNCOMMITTED would be fine if two processes are not likely to collide in this way. However, since a call to the create* method is quite short, it is unlikely that the SERIALIZED will cause problems, as long as the database platform supports it.

Answer 2

Increasing the database.maximumPoolSize size from 3 to 5 solved the error.

Answer 3

Had the same issue in a Spring Batch application (Spring Boot 2.3.3). The solution was:

1. Remove @EnableTransactionManagement from a @Configuration class where datasources are configured. (@Transactional should also be removed.)

2. Add the following to application.yaml

    batch:
      repository:
        isolationlevelforcreate: ISOLATION_READ_COMMITTED

Answer 4

I had the same problem, and effectively isolation in jobRepository level is the key, here is an example of code that works for me:

<batch:job-repository id="jobRepository"
    data-source="dataSource" transaction-manager="transactionManager"
    isolation-level-for-create="READ_COMMITTED" table-prefix="SB_" />   

Answer 5

I have got a workaround for this issue.

Follow below step.

1. Manually create table in your database (Link).
2. insert some dummy records in BATCH_JOB_INSTANCE, BATCH_JOB_EXECUTION and BATCH_JOB_EXECUTION_PARAMS table. (don't forget to commit)
3. Error solved. enjoy.

Answer 6

I was able to resolve this error by adding isolationLevelForCreate like below:

<bean id="jobRepository" class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean">
        <property name="databaseType" value="ORACLE"/>
        <property name="dataSource" ref="dataSource" />
        <property name="transactionManager" ref="transactionManager" />
        <property name="isolationLevelForCreate" value="ISOLATION_READ_UNCOMMITTED"/>
    </bean>
