Spring Batch Framework - Auto create Batch Table

Question

I just created a batch job using Spring Batch framework, but I don't have Database privileges to run CREATE SQL. When I try to run the batch job I hit the error while the framework tried to create TABLE_BATCH_INSTANCE. I try to disable the

<jdbc:initialize-database data-source="dataSource" enabled="false">      ... </jdbc:initialize-database> 

But after I tried I still hit the error

org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [SELECT JOB_INSTANCE_ID, JOB_NAME from BATCH_JOB_INSTANCE where JOB_NAME = ? and JOB_KEY = ?]; nested exception is java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist 

Anyway can disable the SQL, I just want to test my reader writer and processor work properly.

Answer 1

With Spring Boot 2.0 you probably need this: https://docs.spring.io/spring-boot/docs/2.0.0.M7/reference/htmlsingle/#howto-initialize-a-spring-batch-database

spring.batch.initialize-schema=always 

By default it will only create the tables if you are using an embedded database.

Or

 spring.batch.initialize-schema=never 

To permanently disable it.

Answer 2

Spring Batch uses the database to save metadata for its recover/retry functionality.

If you can't create tables in the database then you have to disable this behaviour

If you can create the batch metadata tables but not in runtime then you might create them manually
