Error description
The problem is reproducible in WebSphere Application Server operations cascaded from parents to children and grandchildren. When you do the following a DataBase constraint violation occurs: 1) Start a transaction 2) Load a Parent instance from the database 3) Navigate to a Child and modify it 4) Cut the relationship between Child and GrandChild 5) Cut the relationship between Parent and Child 6) Commit the transaction This results in a stacktrace: Caused by: org.apache.openjpa.lib.jdbc.ReportingSQLException: ORA-02292: <detailed error message here) WHERE ID =? [params=?]} [code=2292, state=23000] at org.apache.openjpa.lib.jdbc.LoggingConnectionDecorator.wrap (LoggingConnectionDecorator.java:273)

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V8.0.0 and V8.5.0 who make * * use of the orphanRemoval=true * * property on their JPA relationships where * * the Entity contains database foreign key * * constraints. * **************************************************************** * PROBLEM DESCRIPTION: Constraint violation exception when * * removing relationship using * * (orphanRemoval = true) * **************************************************************** * RECOMMENDATION: * **************************************************************** The problem occurs with the following relationships between classes: Parent ->* Child ->* GrandChild. Class Parent has a collection of Childs. Class Child has a collection of GrandChilds. In the database a foreign key constraint is define on the necessary classes. Each one-to-many relationship is annotated like this: @OneToMany(cascade = CascadeType.ALL, orphanRemoval=true,...) That is we use orphan removal and remove operations cascade from parents to children and grandchildren. When we do the following a DB constraint violation occurs: 1) Start a transaction 2) Load a Parent instance from the database 3) Navigate to a Child and modify it 4) Cut the relationship between Child and GrandChild 5) Cut the relationship between Parent and Child 6) Commit the transaction In this scenario the following exception will occur: Caused by: org.apache.openjpa.lib.jdbc.ReportingSQLException: DELETE on table 'CHILD' caused a violation of foreign key constraint 'SQL120320110237861' for key (11). The statement has been rolled back. {prepstmnt 1074806800 DELETE FROM CHILD WHERE ID = ? [params=(int) 11]} [code=20000, state=23503]
Problem conclusion
With this fix, code has been added to OpenJPA to properly remove an orphan object when database foreign key constraints exists. The fix for this APAR is currently targeted for inclusion in Service Levels (Fix Packs) 8.0.0.5 and 8.5.0.1 of WebSphere Application Server versions 8.0.0 and 8.5.0.
