I am getting this exception with SERIALIZED isolation level on JobRepository in Spring Batch:
org.springframework.dao.CannotSerializeTransactionException: PreparedStatementCallback; SQL [INSERT into DATAFEED_APP.BATCH_JOB_INSTANCE(JOB_INSTANCE_ID, JOB_NAME, JOB_KEY, VERSION) values (?, ?, ?, ?)]; ORA-08177: can't serialize access for this transaction

when runing only one job, nothing else in parallel. When I change isolation level for JobRepository to ISOLATION_READ_COMMITTED the exception is gone.
What is the reason of this exception?
回答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.
回答2:
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_" />
回答3:
When using serialized transactions you need to increase the initrans parameter on the table per the Oracle Docs. To handle serialized transactions this needs to be 3 or more.
alter table BATCH_.... INITRANS 3
回答4:
We have tried jacking up INI_TRANS to 100 and we were still running into issues
I found this article that suggests adding ROWDEPENDENCIES to the creation of tables.
http://www.devx.com/dbzone/Article/41591?pf=true
For me with INI_TRANS & now ROWDEPENDENCIES the exceptions for Serialized have gone away.
Update: Turns out not to be a perfect solution. We did have one event of this SERIALIZED exception happen over night. Now that's much better as we had 100s of runs before a single failure but it appears that using ROWDEPENDENCIES isn't a yet a complete solution.
回答5:
I have got a workaround for this issue.
Follow below step.
- Manually create table in your database (Link).
- insert some dummy records in
BATCH_JOB_INSTANCE,BATCH_JOB_EXECUTIONandBATCH_JOB_EXECUTION_PARAMStable. (don't forget to commit) - Error solved. enjoy.
回答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>

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