[Hibernate-JIRA] Created: (HHH-5436) different lock deepness for joined subclass

by kakusi kakusi (JIRA)

different lock deepness for joined subclass ------------------------------------------- Key: HHH-5436 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5436 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.3.2, 3.2.5 Environment: Oracle 10g Reporter: kakusi kakusi Hi, we use hibernate, oracle and pessimstic locking, to avoid concurrent modification through different threads. This worked fine for a while. But now we sometimes get deadlocks. We analyzied and found the cause: we produced locks with different deepnesses for objects of type joined subclass. An example for our kind of mapping: {noformat} <class name="TraceObject" table="TraceObjects"> <cache usage="read-write" /> <id name="objectId" column="objectId" type="long"> <generator class="native"> <param name="sequence">TraceObjectsSeq</param> </generator> </id> <timestamp name="dbVersionControl" /> ... </class> <joined-subclass name="VehicleObject" table="VehicleObjects" extends="TraceObject"> <key column="id" /> ... </joined-subclass>{noformat} Method: {{session.get(Class clazz, Serializable id, LockMode lockMode);}} Created Select-Statement: {{SELECT traceobjec0_.objectId ... FROM TraceObjects traceobjec0_ LEFT OUTER JOIN VehicleObjects traceobjec0_3_ ON traceobjec0_.objectId=traceobjec0_3_.id WHERE traceobjec0_.objectId=? FOR UPDATE;}} Effect: This locks the relevant data in table TraceObjects and joined table VehicleObjects. Method: {{session.get(Class clazz, Serializable id);}} {{session.lock(Object object, LockMode lockMode);}} Created Select-Statement: {{select traceobjec0_.objectId ... from TraceObjects traceobjec0_ left outer join VehicleObjects traceobjec0_3_ on traceobjec0_.objectId=traceobjec0_3_.id where traceobjec0_.objectId=?;}} {{select objectId from TraceObjects where objectId =? for update;}} Effect: This only locks the relevant data in table TraceObjects. We think this is a bug, because all techniques to lock should create the same lock type (only locking the parent table). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
