Hello Follks,

I have an application with a Spring Process Engine configuration that fails to start. The database is comopletely empty, i am creating the Database with : <property name="databaseSchemaUpdate" value="true" /> but it fails with the following error

Caused by: org.camunda.bpm.engine.OptimisticLockingException: ENGINE-03005 Execution of 'UPDATE PropertyEntity[next.dbid]' failed. Entity was updated by another transaction concurrently.

It all works fine with a H2 database, with the file based database the application starts and i can complete my workflow.

there are no other servers or camunda engines in play.

Configuration

<bean id="processEngineConfiguration" class="org.camunda.bpm.engine.spring.SpringProcessEngineConfiguration">
    <property name="processEngineName" value="default" />
    <property name="dataSource" ref="camundaDataSource" />
    <property name="transactionManager" ref="transactionManager" />
    <property name="history" value="audit" />
    <property name="databaseSchemaUpdate" value="true" />
    
    <!-- get jobs by "ascending due date" so timers are fired earlier -->
    <property name="jobExecutorActivate" value="true" />
    <property name="jobExecutorAcquireByPriority" value="false" />
    <property name="jobExecutorPreferTimerJobs" value="true" />
    <property name="jobExecutorAcquireByDueDate" value="true" />
    
    <property name="deploymentResources" value="classpath*:*.bpmn" />
</bean>

Any Ideas what is wrong here

More specifically this is the oracle banner seen as a result of SELECT * FROM V$VERSION
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production

Camunda version is 7.8.0

Oh and i just reverted the project to version is 7.7.0 and it is working correctly, something in the newer 7.8 version seems not to be working correctly with oracle

Hi,

a subtle difference could be the SQL batching. Perhaps disable this in the latest version with;

property name=“jdbcBatchProcessing” value=“false”

See if that makes a difference?

regards

Rob

Hi @Webcyberrob, thanks for your input, indeed it is now working with the jdbcBatchProcessing="false"setting.

this should be working for Oracle 12 but potentially my database has some compabilty mode that i cannot see with my Oracle user. Found more info relating to this here :Error Delete Deployment - #9 by sdorokhova

Make sure to use the Oracle 12 JDBC driver as well.
